Moving up a tier
Pros: Great build quality, good noise cancelling, versatile W-shaped tuning, wide soundstage, good battery life
Cons: Sound imaging/bass impact can sound a tad distant, can't use LDAC and multipoint simultaneously, pressure/movement affects bass, hiss with ANC on.
The Soundcore Space Q45 is Anker’s latest over-ear flagship. As with its predecessors it provides a respectable feature set, but has moved up a tier in terms of pricing. Is it still able to hold up?

Over the past 2 years I have been using the Soundcore Life Q30 as my main daily driver. For below 100$ it served well but had a few shortcomings that reiterate the fact you get what you pay for.

Design 8.5/10​

I wasn't a big fan of the previous Q30/Q35 design aesthetic which felt like it was a clash between modern and retro design. Although the basic design is not that different on the Q45, it overall looks more aesthetically pleasing and fits its "Space" name. The build quality is very good even though most parts are plastic. There is little to no creaking of the headband or hinges which was one issue I have had with some other headphones at or beyond this price point. The main issue with the design is that the earcups protrude out a fair bit which makes them a tad unwieldy. These do fold flat and come with a hard carrying case. The case exterior is fine but the inner plastic frame is loose and cheap, leaving no good place to put your cables. I’d rather take it out and fold it in or better yet use a carrying pouch instead.

Comfort 7/10​

The earpads are memory foam and quite comfortable, but a tad lacking in breathability which contributes to the air pressure issue I will detail later. The headband under certain conditions does exert some pressure leading to a fatiguing “hot spot” on the forehead.

Controls/Connectivity 8.5/10​

In terms of headset controls you get the usual in the form of button controls. This feels old-school but at least the buttons are responsive and reliable. One feature sadly removed from the Q30/Q35 is quick attention mode which used a touch sensor to quickly open the transparency mode.

The Q45 has a robust set of customizability options using the Soundcore app. This includes changing the EQ settings and ANC settings. Personally, I set it to only cycle between transparency mode and ANC. Having previously used the Soundcore app for my Liberty 3 Pro, these work just as well.

These support multipoint and their implementation is improved over the Q30 in that they remember the 2 devices you have connected to. There is LDAC support but sadly not with multipoint. The Bluetooth connectivity is good but I would put it slightly behind the Q30. I have experienced occasional dropouts and audio pops/crackles especially when using multipoint. For my home usage, I have found that connectivity is actually more stable with LDAC turned on, probably because multipoint is disabled.

Active Noise Cancelling 8/10​

The ANC of these headphones is a substantial improvement from the Q30 which I was rather underwhelmed by. The Q45 does a good job removing mid to low frequencies, and the ANC level is adjustable from a scale of 1 to 5. It doesn’t do too much for higher frequencies though, and increasing the ANC to higher levels will increase the hiss at higher frequencies.

However, there is a major problem I have experienced using ANC or transparency of this headphone. When moving my head at a certain angle, the volume especially of the bass oscillates abruptly in response to the change in air pressure. Many ANC headphones I have tried have this similar issue, but it seems far more pronounced on the Q45 than other headphones I have tried. For comparison this issue exists in the Q30 but only happens when I shake my head vigorously. Soundcore support sent me a replacement unit and it still has the same problem, albeit slightly less severe. I usually don’t notice this phenomenon unless I am actively moving my head or during a bumpy commute, but on some bassier tracks and with the ANC setting at higher levels it becomes more noticeable.

Another issue I have noticed is an intermittent subtle popping sound coming form the left earcup when music isn't playing. I do wonder if this could be a defect with the internal amplifier but when wearing the opposite earcup I do not notice the issue so I suspect it has something to do with my hair and mic feedback.

Battery Life 9/10​

The battery life is a respectable 50 hours with ANC turned on. However, it does drain faster when using LDAC. I do find I have to charge these every week or so for relatively heavy usage using LDAC or multipoint, which translates to roughly 25-30 hours of battery.

Sound Quality 8.5/10​

The overall audio presentation of the Q45 is a W-shaped signature, with peaks in the bass, mids and treble. The frequency response measurements show several dramatic peaks, but although this looks unnatural the Q45 is quite versatile and respectable. The bass reaches fairly low but is a tad lacking in terms of thump, but overall well-controlled and not bloated. The midrange is mostly focused at the centre with a slight slant to the upper mids - vocals and drums both present nicely. The treble takes a slight backseat but has good sparkle and extension nonetheless. Overall, the default tuning works well for a wide variety of genres, and you have some flexibility adjusting it to your liking with the EQ.

In terms of imaging, the presentation is a tad distant, as if I am in the middle row of a concert rather than the front row. The bass takes a hit especially as while it is rather deep and punchy, I feel like the impact could be more visceral. That is not necessarily a bad thing as consequently the soundstage is quite wide with excellent detail retrieval and instrument separation.

With the default sound signature there is the option to boost the bass with a “bassup slider”. With the initial firmware this increased the midbass causing it to bleed into the mids, but since firmware 2.17 both the sub-bass and midbass are heavily boosted to be too overpowering and unnatural for my ears, so I currently do not recommend using this setting for most situations.

Conclusion​

Overall these are a great midrange ANC headphone with excellent sound quality, build quality and robust app support, but going up one budget tier leads to some reservations with the various issues I have mentioned. My main issue with these is the ear pressure issue which makes these a poor choice for bumpy commutes or usage with heavy movement, but I do not know if this issue affects all units the same way. Otherwise, these are well worth being a step above Soundcore's previous ANC headphones.

Overall Score - 8.5/10​

Comparisons​

vs Soundcore Life Q30
The Q30 is certainly still respectable if you can get it for a discounted price, but the Q45 is clearly a step-up addressing many of the issues I have had with the Q30, especially build quality, sound quality and ANC. Q30 does feel a tad more comfortable as although its earcups are shallower, its earpads seem a bit more breathable and the pressure issue I have experienced is almost absent on the Q30 (unless you shake your head vigorously or are on a very bumpy commute).

vs 1More Sonoflow
The Q45 has superior build quality with almost no creaking on the headband and hinges, two gripes I had with the SonoFlow. It also offers better ANC and transparency mode. The Q45 also has a more refined treble, but if you are after bass impact and a more intimate presentation, the SonoFlows have a tighter, harder-hitting bass. The SonoFlows also allow you to use LDAC with a multipoint connection, but the implementation of multipoint is cumbersome in that it only remembers and connects the most recently paired device, so you must always manually add the second device for multipoint.

vs Soundcore Liberty 3 Pro (sound comparison)
Both of these have a W-shape but are quite different. The Liberty 3 Pro puts much more emphasis on the treble and bass, with much more visceral impact and low end extension. The mids are more slanted towards the upper-mid/lower-treble which can sound a tad thin.

vs Soundcore Space A40
As the concurrently-released true wireless earbuds, the two complement each other nicely although their tunings are rather different. The A40 is relatively flat missing much bass impact and treble extension, but has an odd 7.5 kHz treble peak which adds a nice airiness in some tracks but other times sounds unnatural.

Decent budget option but misses the mark beyond
Pros: Simultaneous LDAC and multipoint support, flat response, crisp upper mids,
Cons: Uninspiring design, clunky headband, mids sound thin, lacks treble extension, limited EQ options, dodgy multipoint implementation
Please read elsewhere if you want reviews that cover all the bells & whistles . I focus on the critical points for the purposes of this review.

The 1More SonoFlow aims to bring ANC and LDAC to the masses for a reasonable price, but how well does it deliver? Stay tuned to find out.

My first Bluetooth headphone was made by 1More - the MK802. This stylish headphone had great headband build quality and good sound for the price, but my main issue with it was the comfort as its small earcups rendered it more like an on-ear design for larger ears. Since then, my experience with 1More has been somewhat mixed. I enjoyed the Triple Driver IEMs but found them a tad difficult to stay in my ears, while the 1More Dual Driver ANC True Wireless had a similar issue and poor battery life which prompted me to return them.

Design + Build quality 5/10​

1More usually excels in the design, but this headphone is a major letdown. The overall appearance of the headphone is fine, though when you are wearing these nothing really stands out as the bright red accents inside the earcups would be concealed.

The earcups are exactly the same design as the 2-year old Tranya H10, right down to the button layout and microphone ports. It is possible 1MORE was involved in the development of the Tranya but I could not find any information to confirm this. The earcups are a bit on the small side for an over-ear and therefore not very breathable, though comfort is fairly decent. The headband is completely redesigned, but not for the better. The material is a cheap plastic, which constantly makes a clunking sound somewhere at my slightest head movements. The problem seems to be coming from the headband itself rather than the hinges, and the lack of screws on these headband parts means this problem cannot be easily addressed.

Controls and Connectivity 7.5/10​

The SonoFlows offer a lot in terms of connectivity, supporting SBC, AAC and LDAC. The connectivity tends to be great if you are using it on one device, though I have experienced intermittent dropouts in busy areas.

I commend 1More for giving these the ability to use LDAC AND multipoint at the same time. Generally the connectivity is consistent, but sometimes it will inexplicably disconnect from my phone altogether when I also have it connected to my laptop (both on Bluetooth 5.0). There’s also a catch with the multipoint - similar to the Soundcore Life Q30, they only remember the last-paired Bluetooth device the next time you turn it on.

There is app support but I find the options rather limited. There's currently no custom EQ and the app overall feels rather like a beta version.

The control scheme is similar to other similarly-priced headphones. Everything is on the right earcup which makes things far more convenient. The physical buttons are nice and responsive. However, I do find it a bit awkward the power button which is also used for play/pause is on the front side while the other buttons are on the back. Additionally, the volume down button is used to switch to the next track which is the opposite of many other headphones.

Sound quality 7.3/10​

These are decent/respectable for a sub-100$ headphone but nothing more. The overall tuning is warm with a relatively flat low end. The mids have some emphasis so vocals sound clear and crisp, but the lower mids lack body so snare drums sound hollow and thin. The treble has a little bit of sparkle but rolls off relatively quickly with the lower treble sometimes sounding splashy.

The wired connection uses a 2.5mm port, so you will need to use this type of cable with the SonoFlows. Sadly, you can’t use ANC or transparency as the headphones are entirely passive when wired, and the sound quality takes a hit. The tuning changes considerably with the overall sound becoming even warmer.

Noise Cancelling 7/10​

The ANC is decent but not much to write home about. It does a decent job removing mid to low frequencies, but falls apart when used in busy settings like commuting and doesn’t remove much of the higher frequencies.

The transparency mode leaves something to be desired. First you have to cycle between ANC-Transparency-Off which can be rather tedious. There is a noticeable amount of hiss but it does a decent job picking up your surroundings clearly, and I can carry conversations just fine most of the time. However, my own voice sounds muffled and thin relative to background noise. In some situations I wish it was louder. In comparison, the SoundCore Q30 and Q45 have a warmer transparency mode that sounds more natural, but this makes it harder to carry conversations without turning down the volume (and to make matters worse, there is an EQ shift in ANC-off and transparency mode where the bass becomes stronger).

Conclusion​

With the initial marketing hype, the Sonoflows seemed like a promising option aiming well above its price point. In the end, you get what you pay for. Although a decent budget option, I can’t help but feel they have missed the mark and do not present anything new to the table. For an 80$ headphone it is certainly a decent choice and I hope other brands follow suit with similarly-priced options under the same feature set.

Comparisons:
Soundcore Life Q30
In terms of sound the 1More has a tighter presentation with crisp upper mids and a tight bass response, whereas the Life Q30 sounds a tad boomy and warm. Neither headphones excels in the treble with a similar roll-off. The Q30 has a “Piano” EQ preset which is similar to the Sonoflow but more boomy in the bass. The soundstage is considerably wider and deeper. In terms of ANC, the Sonoflow does a better job overall, but the Q30 has rather mediocre ANC to begin with. Note that newer versions of the Q30 come with firmware 2.3 which have ANC/amplification disabled when using a wired connection, possibly using a similar chipset to the Sonoflow.

Soundcore Space Q45
The Q45 definitely shows as higher-tier headphone with a more premium build quality. The sound is more refined with a crisp treble and better extension. The ANC is also considerably better. The multipoint connection is simultaneous between two devices but is disabled when using LDAC.

Dyplay Urban Traveller 2
This 3-year-old headphone still has one of the best ANC I have tried at this price point. It is still slightly more effective at blocking out mid-low frequencies than the SonoFlows and either soundcore product. Where it does fall short is the upper frequencies where it hisses a lot and lets in some sounds like the keyboard clicking.

Great ANC for the price but a number of serious issues
Pros: Excellent ANC for the price, organic sound and deep soundstage, great battery life on the earbuds
Cons: Defaults to ANC off, highs lack extension, lower treble a tad peaky, touch controls can fail and other potentially serious QC issues including audio hiss. Mediocre case battery life. Some features need a third-party app to be enabled.
The SoundPeats T2 is the company’s first foray into Active Noise Cancellation. For a reasonable price point they have a lot up their sleeve, but how well do these fare in real life?

NOTICE: I purchased these in April 2021 when it was first released in Canada. SoundPeats has stated the unit I received is the second batch which addresses clipping distortion at louder volumes reported in the first batch.

Design 8/10
Overall the design is a bit uninspiring but decent enough for me. The charging case stands tall and is slim with a soft-touch plastic, but after some time it can get scuffed up easily. It charges with USB Type-C which is a no-brainer at this day and age but unfortunately does not have Qi wireless charging.

Comfort and fit 9/10
The earbuds themselves are quite large but surprisingly comfortable and stay put in my ears very well. They have an ergonomic negative profile - the issue is more into how much they protrude out of your ears than the fit. Therefore they are not ideal for sleeping with or wearing a hat over.


Isolation 6/10, ANC 8/10
Passive isolation
is mediocre, it is fine for most general background noise but does poorly for commuting. For a negative fit design that fits quite nicely and stays in my ears, this is a tad disappointing.

ANC is very good for this price point. It is quite aggressive at removing mid to low frequencies, and takes a slight edge off higher frequencies. It does however, hiss noticeably in complete silence and doesn’t do much for removing the sounds of people talking (especially loudly).

Most concerning is that I notice a slight buzzing artifact after prolonged listening on the left earbud - I hear it regardless of whether ANC is turned on or off. There have been several conflicting reports of this defect, with some users saying it doesn't occur to them or only when ANC is turned on. While it is not too bothersome, it is unfortunate that the second batch has not addressed this issues. [See more about ANC settings with the AirReps156X app]

Another gripe is that the ANC setting is not remembered - these will always default to ANC off each time you power on the earbuds. You also must cycle through passthrough mode in order to activate ANC mode, which is rather tedious.

Controls 5.5/10
These earbuds have touch controls for play/pause, controlling the volume, next track, smart assistant and toggling the ANC mode. Unfortunately there is no previous track button though I just need to say “previous” on the smart assistant on Android.

Holding the touchpad for 6 seconds puts the earbuds into pairing mode. Not as convenient as having multipoint (which is still few and far in TWS), but it does save the step of disconnecting to my current device. Holding the touchpad for about 10 seconds turns off both earbuds. This proves important, because the earbuds don’t power off in the case if it is depleted. The earbuds power off together but need to be powered on again individually.

However, the touch controls have many issues. There is some overlap between the durations, such that sometimes I inadvertently power them off when I meant to go into pairing mode if I just hold it slightly too long. There are also occasions where the touch controls for play/pause and hold (ANC or next track) fail to work. Usually it fails on the right earbud, so next track and play/pause fail to work on that bud. While it can sometimes resolve eventually, the only reliable way to get around this is to re-connect the earbuds. For this reason I have to deduct points for reliability.

Usability + Connectivity 7.5/10
The T2 is also the first SoundPeats product to feature ambient hearthrough, and it is quite a good implementation. The volume stays constant without any fluctuations, so these are great for playing instruments while listening to music. Even though the ambient feed is reasonably loud, it is more emphasized in the higher frequencies, and I have to turn my music way down in order to hear conversations clearly.

These support AAC and SBC codecs. They still sound good even if you’re using SBC on Windows 10. However, with SBC they often start up music with slightly delay on one earbud - not an uncommon issue with true wireless earbuds but it can be annoying in that first second or so. Connectivity is quite solid with very infrequent dropouts (I notice some on my phone when I have its bluetooth modem oriented a certain way, but I’m not sure I can blame the earbuds for this issue which occurs on other devices as well).

On Android, latency in gaming is slightly below average at this day and age. While not as bad as some BT 4.2 or early 5.0 devices, it is quite underwhelming for a new product. On Windows 10 latency is slightly improved but trails behind other contemporary products.

App Support [unofficial AirReps156X]
There is no official app support, but the Android AirReps156X app (designed for Airpods clones and other devices using Airoha chipsets) is partly compatible with the T2. The app requires you to select and connect your device each time you open it but after that you are able to quickly adjust ANC modes and even low-latency mode. Note that the settings made in this app are only temporary and will be forgotten the next time you power on the earbuds.

Among the ANC modes, aside from the default hybrid ANC, you are able to adjust feed-forward and feed-back ANC modes. Feedforward ANC is not as powerful as hybrid mode but emits less overall hiss, and may be better suited for indoor settings. Feedback ANC is terrible - it does not block out much background noise and almost sounds almost like a half-baked ambient mode. You are also able to force transparency mode on using the app, but once you take both earbuds out it will go into default ANC off. I've also had one occasion where after doing this the two earbuds no longer recognized each other as a stereo pair, until I re-paired them.

The AirReps156X also allows you to enable Low Latency mode, but I can see why SoundPeats didn’t include it. On Android, the connectivity suffers quite a bit such that holding my phone around its Bluetooth modem causes several dropouts.

Unfortunately, the equalizer function appears to be disabled by SoundPeats. The app also does not appear to be available for Windows 10 or iOS (understandably so as it pertains to Apple clones). As long as your earbuds are powered on they preserve the settings made on the app and so you can just disconnect then connect them to a second device (eg. Windows 10 laptop). This is the only way on Windows 10 you can use low latency mode, for example. (the connection is much better, probably because SBC is being used instead of AAC).

Sound Quality 8/10
Overall, the tuning is organic and warm, with an emphasis on the bass and lower mids. The low end is punchy without being bloated, while vocals sound full but a tad lacking in upper registers. They don't sound veiled or muffled, just like something is missing up top. The treble rolls off but is a tad peaky/hot at higher volumes. While these can get loud, I have mixed feelings about changing the volume. I generally listen around 70% but sometimes find it a tad lacking in detail, but turning it up brings out the hot lower treble.

The soundstage is intimate but not congested and have a good sense of depth such that layering/instrument separation is excellent, often bringing out elements I don’t really notice before, particularly in the lower mid frequencies without sounding muddy.

My unit is supposedly from the second batch, which SoundPeats claims to address clipping distortion at higher volumes. Unfortunately, the noise floor is rather high such that hissing is quite noticeable, and intermittently I hear a buzzing static from the left earbud. While these are serious reliability issues, I will not be factoring this into the sound quality score as various users have reported not having this issue or being present on the opposite earbud instead.

Battery Life 7/10
The earbuds themselves claim to have up to 10 hours of battery life, though this only pertains to having ANC off. With ANC on, the earbuds last about 6 hours or so. The battery indicator for the earbuds themselves still shows about 90% left after 1-2 hours of use, but drops more abruptly within the last 2 hours or so. Overall, I am still impressed with the battery life but the percentage indicators could be more accurately scaled.

The case seems inefficient in constantly topping up the earbuds to 100%, which leads them to become depleted within 2 days (~12 hours of use), even though the earbuds themselves could last for another full cycle. You also can’t power off the earbuds by closing the case when it is “depleted” (even though one LED is still blinking). If ambient mode is turned on in this situation, putting them in the case will cause a high-pitched feedback sound until you manually turn of the earbuds. Fortunately you are able to power the earbuds off, but having to power them on individually in this situation is cumbersome. Although this is not uncommon among budget true wireless earbuds, the fact that something like Earfun Free Pro is able to still do this has me a bit disappointed.

Overall
In terms of ANC and sound quality, the SoundPeats T2 are a solid presentation for the their ANC earbuds. However, they have a number of serious shortcomings, much of which seem to be down to QC issues (intermittent audio hiss) and software glitches (touch controls failing). For the most part, I can live through these issues which only occurs intermittently, but the uncertainty you may receive a faulty unit prevents me from giving these my highest recommendation.

Small buds that pack a punch!
Pros: Powerful bass response, crisp and clean highs, stays in my ears fairly well, good ANC indoors, good battery life
Cons: Ambient mode is lackluster and doesn't work in single-bud mode, poor ANC outdoors/commuting, no previous track control, occasional dropouts
I first heard of Earfun when they launched an Indiegogo campaign for their first True Wireless earbuds, the Earfun Free. I purchased the special edition which was tuned by Oluv's Gadgets. Though my first impressions were good, my experience quickly went downhill within the first week after one of the earbuds failed to produce sound, and Earfun could only offer a full refund for my special edition product. So with the Earfun Free Pro I was hoping to turn over a new leaf. I bought these during Black Friday/Cyber Week for approximately 50$ US or 65$ CAD. Shipping took approximately 10 days to reach Canada.

Design - 8.5/10

The design is very similar to the FIIL products, essentially being a rebrand of the FIIL T1 Pro. The overall look is rather simplistic and uninspiring, and if I were to nitpick, the placement of one Earfun Logo upside down relative to the other is an odd decision. Unlike the FIIL T1XS, the USB Type-C port supports a true Type C-to-C charging as well as Qi wireless charging. The plastic case is fairly slim and compact, and the earbuds are touted as one of the smallest in the market.

Comfort and Fit - 8/10

The Earfun Free Pro highlights the t difference between seal and fit. These are some of the best fitting earbuds I have tried, staying in my ears when running or dancing. However, their seal can be difficult to nail down and does not lead to tight passive isolation. Shoving them into your ears can sometimes cause one ear to seal with less bass, and other times the flange will flip backwards when you yank them out. You can't really sleep with these without the sound becoming subdued due to the seal dislodging. Third-party tips may work better but I currently don't have any that pair well with the Earfun Free Pro. The 1More ANC eartips worked great as they were basically the same design with a rigid core (think Sony hybrids) but I had to return these.

The earhooks/fins are meant to ensure the earbuds stay in, but after a fairly short span of usage, they will start to expand and become loose. Thus I opted to use the sleeve that lacks earhooks, which still stays in my ears quite nicely.

Isolation - 7/10

Passive isolation is average at best, due to the insufficient seal. The active noise cancelling is a mixed bag. It works quite well for an indoor setting, such as a fan or space heater, but does very poorly outdoors. While commuting, the ANC was actually amplifying higher frequency sounds made by the train at rest.

Sound Quality - 8/10

If you're looking for anything close to an analytical/lean "audiophile" sound, these aren't for you. They have a wide V-shape signature, where the bass is heavily emphasized, as is the treble to some degree. The sub-bass has a satisfying deep, resonating thump, but on some occasions may sound sloppy and loose. Otherwise the bass is well-controlled and doesn't much bleed into the mids, but the midrange is mostly recessed to begin with. The highs have a sweet sparkly tone and have decent treble extension. Instrument separation and soundstage are fairly decent. These have a fairly wide soundstage but it is a tad lacking in height/depth. The overall sound quality you get from these reminds me of some of those budget-level IEMs back in the day that aimed higher than their price point.

Removing the nozzle filters causes the treble to become sharper and more raw, stripping the "sweet" tone from them. I had to do this because even though there was no visible ear wax, I was noticing a dip in volume from the right earbud even after cleaning. While they are usable for me, you might want to put the filters back or add some dense foam into the nozzle if you're sensitive to highs.

As for codec support, these only support AAC and SBC (with a bitpool value of 53). You can’t go wrong with either, though AAC does have slightly more clarity in the highs, and SBC distorts in technical frequency sweeps.

Connectivity 8/10

These use an Airoha chip that supports Bluetooth 5.2. However, the connectivity isn't completely perfect as I experience dropouts occasionally with my phone, especially when putting it in my pocket with its Bluetooth modem facing away from the earbuds (eg. these occasionally suffer from a "death grip" of my phone). This could be down to my phone above all else, but I do see some similar complaints about dropouts.

The Airoha chip also supports McSync, means that you can use the earbuds individually and hot-swap them quite seamlessly. However, I have noticed that if you use an individual bud for too long, you cannot take out the second bud to initiate a stereo connection. Another gripe is that these don't allow for the use of ambient mode when only one earbud is used, unless you have the second bud out of the case or keep the case open with it inside.

The ambient mode is only barely usable. The mic feed is barely loud enough to hear conversations close to you. Music must be turned way down to even hear your surroundings. There's many occasions where I even forget I have ambient mode turned on. Though ambient mode lacks much hiss, it does amplify a very high-pitched EMI sound also noticed with ANC on. When exposed to sudden sounds like thumps or knocks, the mic feed will also distort and negatively affect your music experience. For something such as playing the piano while listening to music, these are not recommended.

These have touch controls you have control over just about everything including volume, but what has been sacrificed a previous track function. I sure like their "forward thinking"! Jokes aside, you are still able to use previous track via voice command on Android, but I was unable to do this on Windows 10. The controls are quite responsive, though occasionally it will register the wrong function if your tap is finicky.

Battery Life 8.5/10

I am very impressed with the battery life of both the earbuds and the case. Being a heavy user with about 6 hours of usage per day, I could use these for about 4-5 days before I have to charge the case. The case actually seems to retain battery just to warn you it is low, but refuses to charge the earbuds at this state. I can understand why they do this (unlike the Galaxy Buds+ which is driven by optics/covering of the case), but it can be confusing to see the lights on the case only to realize later that your earbuds are no longer charging.

One odd quirk is the battery indicator in my Bluetooth settings. It appears to give you an exact number for battery percentage, but it tends to fluctuate unreliably whenever I put them back in the case. Perhaps this is optimized for Bluetooth 5.2 usage, but I cannot test this at the moment as all my devices are BT5.0.

Conclusion

For the price, the Earfun Free Pro has a lot to offer and currently sits at the top of MY list of True Wireless Earbuds. With its deep thumping bass, the sound works well for a wide variety of genres, but may be undesirable for those looking for a more analytical sound. At the same time, however, I can't help but think these don't excel in any particular feature. While the ANC is decent for indoor situations, it performs poorly outdoors, and the ambient mode is lackluster. If you’re willing to look over these compromises, the Earfun Free Pro is a solid option for its price point.

Overall: 8.5/10


Comparisons​

vs. TaoTronics SoundLiberty 94
Both of these feature ANC and an ambient mode. The TaoTronics' ANC does a better job attenuating the lower frequencies and has a more ergonomic fit and seal, though it actually doesn't stay in my ears as well as the Earfun Free Pro. The Earfun do a better job with medium frequencies such as a space heater. The ambient mode and call quality is also superior on the TaoTronics than the Earfun. The TaoTronics have inferior battery life (no more than 2 days/12 hours of heavy use before the case depletes and the earbuds can't be powered off). Their tuning is less bassy but warmer than the Earfun, lacking definition in the mids and highs, with a bloated mid-bass whether you have ANC turned on or off (turning ANC off has the most bass). Personally, I prefer the detailed sound of the Earfuns over the TaoTronics.

vs 1More ANC
In terms of sound, the 1More has astonishing clarity and soundstage which the Earfun can't quite keep up. Though bass heavy and dark overall, the 1More has a more balanced bass, and the treble has crisp metallic texture, which can occasionally sound sibilant, and is also extremely unforgiving of poorly mastered tracks. However, their biggest pitfall for me is the seal and fit, as well as the relatively poor battery life (case lasts barely two days, just like the TaoTronics 94). The ANC is superior to the Earfun while commuting but not by much, and the Earfun has the upper hand in indoor settings. The value of the Earfun, and a number of other issues with the 1Mores made it hard to justify keeping them.

Imo you shouldnt take price in consideration, as with that logic if we compare to say andromedas, kz zst would have all 10 marks considering the price difference :). You compare to other at same or similar price point. If such connectivity problems you describe net 8/10 score, then what would net say a 5? Them not connecting at all? OR what would be 2-3/10? Suppose not receiving the earphones at all from manufacturer, and 1/10 would be not reciving them and being beat up on the street by the manufacturer :).
But understandeable we each have our own views that differ on things , and evolve with time.

Maybe it's just how I was graded back in school or how games are reviewed, but something rated 85% is very good for most uses but already has some reservations so a B+. I wasn't sure whether to round it to 4.5 stars or just 4 stars, but a truly outstanding product would be only above 90% in my book.

The connectivity issue is relatively infrequent, and many other earbuds have had a similar (sometimes worse) with my phone, so I cannot fully blame it on the audio device. Perhaps I should have separated it into "connectivity" and "usability". Previously I gave the Astrotec S60 a 6.5/10 for poor connectivity with the AAC codec, where it would drop out every 5-10 minutes or so. At this day and age I would have given it a lower rating like 4-5/10.

Yeah, not an easy thing rating stuff, and highly subjective unless you spend a lot of time and energy to minimize variables(like connectivity problems due to phone radio/antenna which you mentioned) and have a set detailed system of what looses/gains marks.

So much potential but falls short
Pros: Great sound (under the ideal conditions), excellent detail retrieval and soundstage, solid case build quality, decent noise cancelling
Cons: ANC and sound quality let down by poor seal, short case battery life, minimal app support, unforgiving of "poorly"-mastered tracks, Qualcomm chipset quirks
DISCLAIMER: I no longer have this product. These were my final impressions prior to returning them. It is possible that some of these issues reflect a defect or my own hearing.

Design: 7/10
The earbuds are fairly large and bulky, comparable to similar options from Anker and Sony. They don't have "stems" but the added bulk presumably acts similarly putting the microphones further out.

Build quality: 7/10
The metal charging case is nicely built with an anti-slip rubber bottom. However, the bottom does collect dust and lint quite easily. The earbuds themselves are another story - after repeated usage and removing the eartips/sleeves, the right earbud's housing started making a crackling sound (especially when squeezed) suggesting the plastic seams have become loose. As a result I had to take down some points for this issue.

Comfort and Fit: 5/10
Though the comfort was decent, I struggled to get a seal with the larger earhooks which often pushed out my right ear such that I was hearing less treble than the right, and I was also getting unintentional auto-pauses on the left bud. None of the earhooks fit my ears well, and it was only later I realized these come with an earsleeve with no hooks! With these I was getting a more consistent seal with both ears and therefore a more balanced sound, but they would still slip out after prolonged use, not to mention when wearing a mask with tight ear loops. Wearing detection/auto-pause can't be turned off (only an option whether to resume playback or not) which is disappointing as I had cases of unintentional auto-pauses when I was using ear-hooks.

Isolation 7/10 (ANC 7.6/10)
For my ears these don't fit deep, more like "half in-ears" so passive isolation is medicore. ANC is decent mainly tames down/smooths background noises rather than reducing it. There's also some faint EMI static whether ANC is turned on or off. My commute is still very noisy thanks to the old-generation skytrains. There are two ANC modes - Mode 2 is designed for indoor settings and just sounds less aggressive than Mode 1 - to me it was almost useless. One irritating issue is that ANC setting is not remembered and it automatically starts with ANC OFF when you power them on.

Sound: 8.5/10
Overall, I am very impressed with the sound, which is tuned with a broad V-shape but generally sounds warm and dark. Punchy bass but slight mid-bass bloat. There's a hot spot in the upper mids/treble that sounds borderline sibilant, but the detail retrieval is excellent similar to the 1More Triple Driver IEM. Soundstage and instrument separation is quite spacious with deep layering

NOTICE: This may be down to my own hearing in combination with the poor fit, but I did notice some channel volume imbalance with the left bud often being noticeably louder. Using the earsleeves with no ear hooks/fins, this issue was greatly reduced, though I still noticed a slight slant towards the left channel when listening to mono tracks. For whatever reason the volume fluctuates left and right when changing the volume, and sometimes re-inserting the left bud causes the sound to become more centered for my ears.

Connectivity 8.5/10
Devices tested: Samsung Galaxy Note 9 (Exynos) and ASUS Zenbook Pro 15 - Both support Bluetooth 5.0 + AptX but not Qualcomm TWS Plus

These use an older-generation Qualcomm chip which supports TrueWireless Stereo Plus (unfortunately, I can't test this out), but also has a clunky single-ear implementation where the buds are listed individually will temporarily pause when hot-swapping them. Playing/resuming tracks or changing the volume causes the audio to pan around before it settles. Connection is relatively solid overall at home, but when I was using the left bud independently outdoors in a busy environment, it was very prone to cutting. These have a combination of button and touch controls, but the buttons are ONLY used for toggling between ANC/passive/ambient modes. Most annoying is that these don't remember your set mode, and always power on with ANC OFF, so you must cycle through the touch controls to turn it on through the two modes (high and low) or use ambient mode. Ambient mode is quite clean with a constant level (I can play piano without it cutting or distorting in loud notes), but a bit low in volume. Annoyingly, these default to no ANC or ambient when only one bud is used, and the touch controls are completely disabled so you must use the app to enable ambient mode.

These have a supporting app which is quite slow to connect. Playing music while initiating this app may cause a connection failure until you pause your music. The app does not offer any EQ settings or features aside from toggling auto-resume, ANC/ambient modes.

Battery life 6.5/10
As these require the volume to be near the top (I generally listen between 85-100%), the battery life falls short, especially for the case. I was only getting between 4.5-5 hours at high volumes with ANC. When placed on the desk, these will automatically power off, which may or may not be desireable - you must manually power them on again afterwards. Case battery is quite short lasting between 8-10 hours or spanning1.5 days of general usage. The case battery LED indicator is very inconsistent - sometimes it shows as yellow (medium) but then flash red (low) when I shut the lid and vice versa. I always preferred those step-LEDs as being more reliable than changing colours. When the case is near depleted (still showing a flashing red light), the buds must be manually turned on.

I've also had many occasions where the buds fail to turn on automatically, especially if I take them out of the case too fast. In these cases I have to either re-open the case after a few seconds or manually power them on with their buttons.

Towards the end of my time with these, I started encountering more issues with the case. The left bud would sometimes power on and connect while inside the case, and the case battery started deteriorating, presumably because the charge was "leaking" from this issue.

Conclusion 6/10
The 1More Dual Driver ANC TWS offered a lot to promise but ultimately fall short considering their asking price. The sound quality has the potential to be excellent, but just when they were growing on me, then I ran into more issues and returned them. It is very possible that my unit had some defects, but some of these issues seem widespread and not necessarily absent in other units.

Great value!
Pros: Great feature set for the price, good comfort, solid connectivity and app support, strong bass response, still sounds good with SBC codec
Cons: Uninspired design, creaky plastic hinges, warm/bassy default tuning, treble lacks extension, passable ANC which alters the tuning, must manually connect second device for multipoint
The Soundcore Life Q30 packs a greater punch for its price. Anker's newest ANC headphone has a very strong feature set competing with the big guns.

LAST UPDATED 5/02/2021 after firmware update 2.1.
DISCLAIMER: Newer units ship with firmware 2.3, which unfortunately no longer allows for wired usage with active noise cancelling. It is possible there is a hardware difference as Anker has claimed nothing can be done to revert firmware version and that the chipset manufacturer disabled the function. Older units never received this update.


Design 7/10
The aesthetics of the Life Q30 is somewhat of a mixed bag. It looks to me like a clash between retro and modern. While not terrible, it does feel somewhat uninspired, especially when some lesser-known brands have styles I prefer.

Build Quality - 6/10
The pads and headband are quite well built but it remains to be seen how well they last over time. The headband adjustment hinge and swivels feel a tad cheap and are prone to making clunking sounds while you move your head around. This is one of my pet peeves with over-ear headphones, worse than any microphonic cable or background disruptions so I'll have to dock some points for this.

Comfort 7.5/10
These have good comfort, but the cost of the hinges creaking. If I want to minimize this issue, I have to push down the headband against my head or fully retract the adjustment, neither of which are particularly comfortable.

Sound Quality - 8.6/10
With their default settings and ANC on, these have a very respectable sound that is slightly above its price point. The bass is strong, with a deep sub-to-midbass thump. The lower mids are recessed, while there is some upper-mid emphasis such that vocals have a shimmer without sounding sibilant. Although the treble isn’t veiled or muffled, I do wish it had better extension - the EQ in the Soundcore app is versatile but doesn't bring up enough upper treble energy. Aside from the standard Soundcore Signature preset, I also find the Piano EQ preset great at bringing out some upper-mid and lower-treble energy, though it does also bring up some bass so I recommend adjusting presets accordingly.

Turning off the ANC or using Transparency Mode changes the sonic characteristics considerably. The volume is increased and there is a stronger bass emphasis. While nice for “fun” listening, ANC-On sounds more balanced.

With a cable and no power, these sound rather mediocre, though this is to be expected from most headphones with active electronics. The midbass is overly emphasized and bleeds into the mids. Using an external amp (I only have the Dragonfly Black 1.5 at the moment), the bass is a little tighter but the mid-bass bleed is still present. With the internal amplifier turned on, these sound similar to their respective settings with Bluetooth. One odd quirk is that I am able to power on the headphones but not power them off when I have a cable plugged in. Unplugging the cable will power them off automatically.

UPDATE: I have tried multiple cables with the Life Q30 and the sounds seems to vary quite a bit. The TRRS cable (single button only) from my Sony MDR-1AM2 works very well with the Q30, but the sound seems distorted at higher volumes, especially with the headphones powered onn. Unfortunately, the three-button in-line remote of the1MORE MK802 does not work with the Q30. With the latter cable, the audio quality is also altered considerably - there's a higher perception of reverb and midrange sounds like drums become even more muddled.

The Q30 supports SBC and AAC codecs. The lack of AptX is not a huge issue for me, as both codecs sound very good, with SBC being just a slightly behind AAC in treble extension/detail. On Windows 10, which only uses SBC with these, they are still very good for music listening. They have an SBC bitpool of 52. The default for Windows 10 is 53, so while it means a slightly lower bitrate than default, it should still sound pretty good and comparable to AAC.

Connectivity 9/10
I have experienced next to zero dropouts with this headphone on both my phone and laptop, which support Bluetooth 5.0. Latency is decent but still noticeable for gaming.

These feature multipoint connectivity, but there’s a catch. It only remembers the most recently connected device, so you must initiate multipoint manually each time you turn them on. Another quirk is that they connect to the second device with a medium volume, but adjusting it will cause it to initially spike up to 100%.

These also have app integration which enables you to adjust the equalizer, ANC and update your firmware. One neat feature is that EQ adjustments on the mobile app works across two devices - you can adjust the EQ on your phone while listening to music on your laptop!

UPDATE 5/02/2021 - Firmware 2.1 has somewhat fixed the issue of volume spiking up on PC when connected to two devices. Unfortunately, you still need to pair to the second device manually. Also, after prolonged usage it seems that it will sometimes connect to my PC at 100% volume. I have also noticed the multipoint connection fail for my phone when I am opening/using the SoundCore app on my phone.

Active Noise Cancelling - 7/10
NOTICE:
It has occurred to me there is an issue with the default ANC setting not being remembered, and this issue has not been addressed as of the latest firmware update. I believe this may affect the mixed reactions about the ANC.

The ANC on these is usable but not its strongest suit. The reduction is mainly in the lower and mid frequencies, leaving out the higher registers. Sound with ANC turned on is a tad quieter than ANC off, with less emphasis on the bass. They struggle to cut out the sound of my rotating space heater. Using the Indoor setting on the Soundcore app improves this a bit. However, as of firmware 2.1, the headphones don't remember your ANC settings properly. When powering them on, they always default to an intermediate ANC mode, which is slightly better than Outdoor but not as good as Indoor or Transport, so you must always manually re-select the ANC mode in the app. I wish Soundcore can address this in a future firmware update.


Other features
These have an ambient hearthrough or transparency mode, which sounds very good. You can turn this on and off quickly by placing your hand on the right earcup though unlike Sony's implementation, this is not a quick hearthrough so you must repeat the gesture to turn it on again. The tuning changes to the same as that with ANC off with a stronger bass, so you might need to turn down the volume as well.

Call quality had been a concern among early reviewers, but it appears the problem lies with aggressive noise suppression rather than a poor microphone. The latest firmware update (1.8) improves call quality greatly, albeit at the cost of less noise suppression. Note that not all units have received this update yet. In my experience, calls start out with a bassy "puff" or fuzz in the first second or so, after which the audio clears up.

Conclusion 8.5/10
These are a great package overall with respectable audio quality, decent active noise cancelling and solid connection as well as battery life. For a budget alternative to some of the bigger names the Q30s are a compelling option, but keep an eye out for other emerging options at this price point.

Comparisons
vs. Dyplay Urban Traveler 2

The Dyplay Urban Traveler 2 was my daily driver ANC for the past year or so, and offers good value for its features at the time. They remain at a higher price than the Q30 and at this point I have a hard time recommending the Dyplays over the Q30. The Dyplays remain a step ahead in build quality and styling, with a durable soft-touch plastic and almost no creaking on the hinges. Where they really excel is in active noise cancelling, which is considerably stronger than the Q30s in the low and mid frequencies. They do, however, have a louder ANC hiss/noise floor than the Q30s, and also let in more higher frequencies, amplifying my PC fan noise for example. With ANC on, their sonic characteristics are the polar opposite of the Q30, with a very strong upper-mid and treble emphasis. Although this brings clarity to vocals and treble, it may be too fatiguing in some situations. Personally, I think the Q30s are overall superior in sound quality.

The Dyplays have a more seamless multipoint connection that will pair to both devices almost simultaneously. They do support AptX and AptX LL, unlike the Q30s, but the AptX implemenation introduces crackling or distortion artifacts in certain types of music (not sure what's causing this, but it also occurs with my 1More MK802). Battery life is also poor, at only 12 hours with ANC. Another irritating quirk is that the Dyplays will power off after a minute of inactivity, but as the ANC switch is independent you must turn them off manually to spare the battery. Lastly, the Dyplays lack an ambient hearthrough mode.

Yeah, unfortunately on Windows 10 we're stuck with SBC up to bitpool 53 or AptX. SBC 52 or 53 is quite good for general music listening but does sound a tad behind AAC, and also distorts in more technical tests such as frequency sweeps though this rarely occurs with actual music. Samsung devices distort badly in the highs as their bitpool is 37.

Good reviews, thanks for sharing.
Just picked up a pair after seeing Oluv praise them repeatedly.
For €59 there is nothing to complain about really. I do find the press a bit on the top of my head, more so than my old QC25 that must be lighter (will check that).
Also multipoint doesn't work between my Android and Windows 10, Windows 10 just hijacks the connection it seems.

Didn't have any issues with multipoint connectivity between Android and Windows 10, but I recall reading similar issues and it might be that you need Bluetooth 5.0 on both devices. Either way, it only remembers the last-connected device so you must manually connect the second device.

Complete feature set, decent across the board
Pros: - Complete controls
- Case has USB Type-C
- Good comfort and passive isolation
- Large soundstage with punchy bass and decent treble despite warm tuning
Cons: - Uninspired design, cumbersome controls
- Recessed lower mids, mid-bass bleed with ANC off
- ANC is mediocre and has relatively short battery life
- Static hiss on left bud with ambient mode
- Thumping noise when running, touch control configuration is quirky
- Does not power off when case is low in battery
The TaoTronics SoundLiberty 94 is one of several recently released budget true wireless earbuds with active noise cancelling. With a complete feature set, is it a giant-killer ANC true-wireless earbud?

Last updated 12/19/2020



Design - 7/10
The charging case is a little on the large size, but is fairly rounded so that it should still be quite portable.The charging port is USB Type-C and supports a C2C connection, so you can charge this off a PD charger or with your laptop. The only thing missing is Qi Wireless charging, which I consider a "nice to have feature" but not an absolute must. The earbuds themselves have a nice housing that fits ergonomically into my ears. The housing design looks rather uninspired, unlike the SoundLiberty 79, but fortunately the TaoTronics branding doesn't stick out much in person as it does in the promo renders.-

Comfort and fit 8.5/10
These have a nice negative profile flush in my ears. My only gripe is that the eartips are the shallow, large-flange type rather than typical IEM eartips, so it may be harder to find replacement eartips. They don't fall out easily unlike some other TWS I've used.

UPDATE: Galaxy Buds eartips do fit these such that they can still charge in the case. They offer a deeper fit and slightly better midrange clarity. HOWEVER, the deeper fit also leads to odd sealing issues with my ears.

Isolation and ANC - 7.5/10
Passive isolation is fairly good on these due to the flush fit, similar to wired IEMs back in the day. It doesn't block out high frequency that well though, and the noise cancelling doesn't do much about this either. ANC mainly blocks out noise in the mid and lower frequencies. If you are planning to use ANC while running or working out, I don't recommend these because they suffer from "runner's thud", where loud footsteps will cause the ANC hiss to abruptly thump. While commuting, I noticed less rumble except for the deepest frequencies, but high-pitched sounds like the trains screeching actually sounded more jarring. They also hiss with the ANC, but it is not particularly distracting. However, on my first unit I noticed a high pitched hiss or EMI static on the left bud, only when the ANC was turned off or ambient mode was used. Almost sounded like a cricket chirping. TaoTronics was kind enough to send me a replacement quickly - now the hiss is still present but far less apparent when ANC is turned off, but I still hear a fair amount when I turn on ambient sound. It is likely this varies between units which gives me doubts about the QC.

EDIT: I have decided to split up ANC and passive isolation. The combined score is 7.5/10 but the ANC itself is 6/10 on top of 7.5/10 for passive isolation.

Sound Quality - 7.5/10
Whether you have ANC turned on or off, these have a dark/warm tuning. The bass is rather punchy although it mostly emphasized in the midbass.
ANC ON: The sub-bass is rolled off and the midrange is cleaner but somewhat hollow - the midbass is still quite punchy. The lower mids sound recessed when ANC is turned on, causing snare drums to sound thin. Vocals are clear but a tad thin and lacking in richness. There is some emphasis on the treble so detail retrieval is still quite good and they're by no means muddy. Volume is a tad lower and I find myself often listening above 90%.

ANC OFF: The bass sounds deeper and more punchy, with some mid-bass bleed into the lower mids. Snare drums and kicks sound very impactful but vocals take a slight hit.

Using both AAC and SBC, the sound quality is quite similar, with only a slight degradation when using SBC. The highs are a tad more splashy and the bass more boomy.

Connectivity - 7/10
These are listed to have Bluetooth 5.1 but my current devices are only Bluetooth 5.0. From what I can find, BT5.1 mainly only improves power consumption and connectivity. In my experience, connectivity is only average with my Galaxy Note 9 and ASUS Zenbook Pro 15. They seem to suffer a little from a "death grip", as there is a tendency to cut when I put my hand near the device's Bluetooth modem, though not as severe as some other Bluetooth chips. The chipset is said to be Airoha but it is not as solid as the Jabees Firefly Pro when used with my phone. You can use the earbuds individually and the transition is typically quite seamless, but on some occasions switching buds causes the buds to re-connect. Also, in single bud mode, ambient mode is on by default and can't be turned off with the touch controls.

The control set is quite complete compared to similarly-designed TWS but misses out in execution. To play and pause, you have to double-tap the left earbud. A double tap on the right earbud activates ambient sound, while a hold turns off ANC. Volume control is a single tap left or right, while skipping tracks is a triple tap. Note that activating ambient mode will cause the music to pause, and activating ANC will cause the music to play. You have to be careful of how fast you tap or you might just change the volume instead of pausing the track, not too slow or fast (tap....tap)

As these share some of the same components with the 20Decebel, as of this writing it is compatible with the 20Decebel app. You can use it to turn on and off ANC without pausing the music. The EQ function of this app is not recommended as it dips the volume significantly and doesn't sound very good.

Ambient sound is decent - it is prone to hissing (cricket-chirping) on the left earbud but otherwise the audio feed is quite good and remains at a constant level. It does, however, temporarily shut down when exposed to a loud sound, such as a finger snap or clapping your hands.

Latency is quite good, even for some casual/basic gaming on the PC. Call quality is also pretty decent. Voices sound clear and not muffled. In busy areas, background noise can still be heard but on the plus side these don't apply aggressive noise reduction.

Overall, the connectivity and controls, while complete and decent, leave something to be desired for.

Battery Life - 5/10
*Update - after some more testing, unfortunately the replacement unit has the same if not only slightly better battery life on the case. Within a two days and less than 10 hours of total usage of the earbuds themselves, the charging case becomes depleted. I understand I could probably get another 4 hours in this situation, but the fact that the earbuds cannot power themselves off means they will continue to drain in the case until I charge it. In my opinion, 360 mAh is way too small for an ANC earbud.
With ANC turned on these are rated at 5 hours of battery life and 20 hours with the case, but this only seems to hold up with lower volumes. With my laptop they are only getting about 4.5 hours at about 90% volume. However, I found the case to be very inefficient. Within the first day, I've had the case become depleted after using the earbuds for less than 5 hours. It seems the case starts out strong but ends up dropping rapidly when the LED indicator only shows 2/4. From the percentages in the 20Decebel app, it seems like the battery charges quite fast after only a few minutes, hence the drain.

One annoyance is that these do not power off once the case is depleted, forcing you to have to manually disconnect from your phone otherwise they will constantly drain battery. You won't have any way to power them on again until you get your case charged. On the first unit, the battery started to drain rapidly after the first few charges. On the replacement, the battery seems improved but still rapidly drops when reaching below 2/4. By the time it gets to last LED indicator which blinks rapidly, the earbuds no longer charge or power off.

Overall - 7/10
At this point with few budget ANC true wireless earbuds, the TaoTronics 94 feels like it is trying to be the jack of all trades. As my first foray into ANC true wireless, these are respectable/decent across the board but suffer from battery life and potential quality control issues. Unfortunately, I have to take off points for battery life and the fact that the earbuds don't power off when the case is low on battery. While this is not an uncommon quirk among true wireless earbuds, I believe the 360 mAh case is way too small for ANC earbuds and is not giving me any more than an additional charge of usage.

vs Samsung Galaxy Buds+
The TaoTronics are more comfortable and offer better passive isolation with ANC on top of that. They also do much better on Windows 10 because the bitrate is at its default value. In terms of tuning the two are polar opposites, the lean and bright Galaxy Buds wins out in clarity but is missing the bass.

vs Sabbat E12 Ultra
The Sabbat is a step ahead sub-bass extension, while maintaining midrange clarity. Taotronics can achieve a similarly punchy bass with ANC turned off, but also has some midrange bleed. The Sabbat doesn't seem to resolve details as much but doesn't sound as "splashy". In terms of fit and isolation, the Sabbat E12 Ultra are obviously inferior and I sometime struggle to keep them in my ears.

Great review, thanks!
As today, 09/18/202 are they in the same situation regarding battery life?

Unfortunately it's still the same, I can't get more than 10 hours out of the case and have to charge halfway through the second day.

Great for mobile but not for PC
Pros: - Lean, detailed tuning close to Harman target
- Great connectivity and integration with Samsung devices
- Decent passive noise isolation
- Good touch controls (under ideal conditions)
Cons: - Average to small soundstage
- Low bitpool using SBC codec - distorts with Windows 10
- Edge-tap volume controls can be easily accidentally triggered
- Case battery drains fast, earbuds leak charge after periods of inactive use
- Itchy eartips
The Galaxy Buds+ represented the best that Samsung had to offer in 2020. After using these since March, here are my final impressions.

Design 8/10
These look ok but are nothing to write home about considering the original Galaxy Buds already set a standard for design. The buds seem durable but the charging case feels a tad cheap, creaking a bit when the hinge is pushed around.

Comfort - 6/10
Decent fit but my ears sometimes get rather itchy which is something I don't notice often with other TWS or IEMs. Large tips have the most reliable seal while medium tips are more comfortable, but my right ear seems more loose with them. Standard-type IEM tips don't fit in the charging case, while wide-bore tips with a larger flange work just fine. I also find the large wings/fins to be a tad irritating and don't help too much with letting them stay in place. Nonetheless, I still use them as the fit is not very secure without them. Although these earbuds fit ok, I have deducted points for comfort due to the amount of irritation when wearing them.

Isolation - 7.5/10
I've seen many reports hyping the passive noise isolation as being very good, but I would say only when compared to most TWS. It is more or less average relative to typical wired IEMs I used back in the day. The old skytrain noise and announcements are still loud with these.

Connectivity and Controls 8/10
With my Galaxy Note 9, connectivity is very good. I rarely suffer from "death grip" issues that plague some of the cheaper Bluetooth chips out there. Where they do suffer in performance is in busy areas. While waiting for the bus one day, the audio started dropping out the moment an electronic trolley bus passed by. Dropouts are not pleasant on this earbud, not only just skipping but giving off an electronic sound.

They also support independent earbud usage and have mostly symmetrical touch controls. This means you can use both the left and right bud to switch your tracks forward and back. The compromise is this occupies the double- and triple-taps on both sides, while holds are programmable to be either volume, ambient mode or smart assistant. The Buds+ also allow for an edge-tap for volume which means I can still have volume control with the other two features. It takes some time getting used to but works surprisingly well. However, I have also noticed it can easily be triggered by mistake due to any abrupt motion around my ears. I'd turn this feature off if you plan on using the buds for dancing or running. For the most part, the basic touch controls work well, unless you have long hair. If your hair is partly covering the earbuds, it sometimes struggles to recognize double-taps and end sup pausing the music instead. Hair also causes a crackling/rustling sound in ambient mode, and it seems worse on the left bud than the right bud.

Gaming mode does decrease latency and is comparable with Bluetooth on Windows 10, but on my Note 9 in-game performance suffers. The audio will also stretch/distort to keep up with the games. Even turning it off, it still happens occasionally, which may be reflecting how the Buds+ scalable codec is handling latency by altering bitrates. Newer devices might fare better.

Call quality is pretty good but when using Zoom on my PC, the other end thought my voice was a tad faint. For whatever reason, I also found connectivity to be slightly worse on my laptop than my phone.

Ambient Mode 7/10
Ambient sound started out decent but in my opinion it has changed for the worse in subsequent updates. I can generally converse people alright, but I do wish the sound was a bit more full in the mids and clearer in lower ambient sound settings. One gripe I've always had is that the audio feed is not constant - the more exposed to loud sounds, the more the ambient feed drops. For example, when playing the piano the volume can become so faint after a few minutes I must re-insert the buds/restart ambient mode to get the original volume back. In response to wind noise complaints, Samsung also added a wind reduction algorithm to the audio feed, but now it missing more of the lower frequencies and the high frequencies are boosted. It also pans left and right when exposed to louder sounds, making them unusable for some purposes - I feel especially unsafe walking outdoors with cars passing by because of this unpredictable panning.

Audio quality
Audio quality is great through my Note 9. The tuning is definitely on the brighter side and is quite detailed. Since the software update in April, the treble is less fatiguing and the bass a bit punchier. Soundstage is a tad small/intimate though instrument separation is excellent so they don't sound congested by any means. Overall, these closely follow Harman Target and sound rather bright, if you want something with deeper bass and warmer midrange I'd suggest looking elsewhere. Overall I don't find them sibilant and fatiguing, but I can definitely see people will consider it as such.

I've also noticed a slight but noticeable channel imbalance with more sub-bass and treble to the left. I've encountered this issue on several TWS and may reflect poor QC. That said, it's not as severe as some other products and RTINGS.COM had measurements seem to show a slight deviation in these areas as I have noticed, it might just be that my ears are more sensitive in these areas.

However, the sound quality suffers on my Windows 10 laptop with Bluetooth 5.0. Although it is still usable for general purposes, the audio has a tendency to show compression artifacts in certain situations. It seems like the Buds+ defaults to a low bitrate with SBC codec (bitpool is 37 instead of the Windows default 53), causing the highs to distort on some tracks. It is especially noticeable for orchestral music with strings/violins. Although some users have reported no issues with Windows 10 (which could be related to drivers and maybe some devices that do support AAC)., the fact that it occurs on my phone with SBC as well as my laptop prevents me from fully recommending this product all across the board.

Audio quality (Mobile) - 8.7/10
Audio quality (PC) - 5/10



Battery Life 6.5/10
The battery of the buds themselves have great battery life as promised, getting around 8-10 hours with higher volumes, but the charging case drains fairly quickly under heavy use. Sometimes within the first day using the buds intermittently for a total of 6-7 hours, the case gets depleted. I have also noticed one earbud sometimes drains much faster than the other, especially after the case becomes depleted. On the positive side, these are one of only a few TWS I've tried which properly power off even after the case is depleted. I suspect they depend on something covering the touch or proximity sensors rather than the charging contact pins.

The case supports USB Type-C charging as well as Qi wireless charging. One quirk I noticed is that in hot conditions, the earbuds sometimes don't charge wirelessly. This appears to be a safety precaution, along with some user reports of the buds powering off in direct sunlight, but is irritating nonetheless. For comparison, Sabbat E12 Ultra is able to charge wirelessly in the same conditions, but the earbuds get extremely warm.

Conclusion
Overall, these are a great TWS for mobile due to their lean and detailed sound and good connectivity. As long as your device supports either Samsung Scalable or AAC codec and can access the Galaxy Gear app, you should be good to go. Unfortunately, I cannot recommend these for devices that only support SBC (such as many Windows 10 and older Android devices), due to the lower than average default bitrate.

Mobile rating: 8.5/10
PC rating [Windows 10 or older on SBC]: 6/10

Update 2021 - Long-term impressions/issues

The battery holds up poorly over periods of inactive use. When I left these for about 2 weeks, the right earbud would be completely depleted as would the case. The LED indicator will display green as if both buds are fully charged, but repositioning it will cause it to turn red, and the buds will start to charge VERY slowly. This does not occur when I use them regularly, but I do suspect the charge to be leaky on the right earbud.

With Windows 11 (currently on Beta) and possibly the final build of Windows 10 (I cannot confirm this), Windows has implemented AAC codec support. Finally the Buds+ are usable on PC for music listening! AAC sounds similar in quality to Scalable, but perhaps slightly less refined in the treble. Connection is fairly stable, but they drop out more easily than my other Bluetooth devices (if I walk from my computer room to the kitchen for example).

Hi, thanks for the review!
I thought the Harman Target has a warmer, bassier tuning than the Diffuse Field. Am I in error?

Sorry for the late reply, but I recall the in-ear target has a focus on the upper mids and treble.

Review will be updated to reflect usage with AAC on Windows 11 Beta.

Pros: Good feature set for the price - USB Type-C charging, decent ANC, excellent Bluetooth connectivity, good treble detail and soundstage with ANC + wireless
Cons: Mediocre battery life with ANC, bright treble with ANC on, distortion with AptX, auto-power-off and volume limiting.
Last year, many Bluetooth budget headphones offered active noise cancelling as well as aptX codec, but most were missing one seemingly minor feature - the lack of USB Type-C charging. With a stylish design and some improvements over the previous model, the Dyplay Urban Traveller 2.0 is one of the few available but emerging options to have this particular feature. Early reviews suggested it had very good noise cancelling and sound quality for the price, but does excel beyond its price point?
20200120_131746.jpg
I bought these off Aliexpress on Black Friday. Shipping via UBI to Canada took approximately 2 weeks.

Design 8.5/10
For a budget product, these have very nice build quality and aesthetics. I really dig the orange accents on the grey soft-touch plastic finish - a nice departure from the typical glossy plastic found in headphones at this price point. Although there is some slight clicking noises, the hinges don't creak or squeak as much as some other plastic headphones. They fold flat (with earcups facing out when around your neck) as well as inward so they can be compacted into the carrying pouch. It would have been nice to see a hard carrying case though, as the original Urban Travellers had this.
20200121_164723.jpg
The headband is padded with rubber while the earpads are made of gel. They appear to be not readily removable. The ANC switch is on the left earcup while the three multi-function buttons are on the right earcup. ANC operates independently of the Bluetooth power.

These have a USB Type-C charging port and supports a Type-C to Type-C connection. This means I can charge it directly off my Type-C laptop, unlike some other products out there which only support Type-C to A connections. Charging speed is quite fast - it took about 45 minutes to go from the "low battery" warning to a complete charge. They also have a 3.5mm port for wired audio.

Comfort 7.5/10
These headphones have gel-cushion earpads which are quite plush and comfortable. They are similar to memory foam but a tad more firm. They also trap a bit of heat meaning your ears will stay warm, but it may be hot on summer days (in the cold Canadian winter I have yet to test this out!). The headband does not have much adequate padding, with the inner section being made of rubber. Clamping force is ok, but they do press slightly against the top of my head. I've noticed that after a long listening session, they do exert some strain on my forehead, and the fit is a tad loose around my ears. Shaking my head vigourously will cause the headphones to slip off fairly easily. Indeed I found that laying back slightly on a reclining chair was enough for the headphones to gradually start slipping off from my ears.

Isolation - 8.5/10
The Urban Traveller 2 touts dual-mic noise cancelling. In my testing, I found it does very well for low frequencies, effectively removing the droning sound of my ceramic heater or the low-frequency rumble while commuting. However, it does not do much to remove high frequency noises. I can still hear my laptop's cooling fan or the higher frequencies of vehicle noise and people talking, although it is slightly attenuated by the passive isolation. ANC also adds a fair bit of hiss and is sensitive to sudden vibrations which cause it to distort. I do not recommend these for running. For everyday non-active usage, I find that these headphones do a very respectable job with ANC at this price point, but the way it handles higher frequencies and sudden noises sees something to be desired.

Sound quality - 7/10
Overall, the sound quality is a mixed bag and varies greatly on how you are listening to these, in particular whether ANC is turned on or off. Thus I have separated the impressions accordingly:

ANC off and wireless - They sound relatively balanced with some emphasis in the bass. The sub-bass is punchy without drowning out the mids. The treble has some decent sparkle but there is also somewhat of a muffled tone. That said, if I didn't know how these sounded with ANC turned on, I probably wouldn't mind this tuning as it is still quite decent. 7/10

ANC on + wireless - The muffled tone of the mid-bass/lower-mids is gone and the treble is greatly emphasized, giving a sense of more detail and a larger soundstage. The bass is very well-controlled in this mode, lacking any sense of bloat or boominess while still having a good amount of punch. There are occasions where it does lack a bit in impact though. The lower mids sound recessed while the upper-mids have some emphasis towards the lower treble, although vocals tend to sound crisp. Although I personally prefer this lean, detailed tuning, I can see how those who are sensitive to sibilance may be put off by it. 7.5/10

Wired playback is rather muffled in the lower mid-bass and the highs sound rolled-off, even more so than ANC-off + Wireless. I would only use it as a last-resort when the battery is drained. Turning on ANC brightens the treble significantly and reduces the bass, even more so than ANC-on +wireless. The treble is borderline sibilant in this configuration and I need to turn the volume down considerably - avoid if you have treble-sensitive ears. 5/10

The Urban Traveller 2 supports the AptX codec which should offer better quality than SBC or AAC, but I have noticed a few situations where it actually sounds worse. In certain tracks, usually when a snare drum hits hard, using AptX seems to introduce a crackling or plosive sound that occurs intermittently left and right. An example of where this occurs is in the intro of Luv(sic) Part 3 by Nujabes (Modal Soul version), when the DJ-scratches come in. Upon further testing my older 1More MK802 also exhibits the same behaviour. AAC or SBC playback doesn't have these issues, and the volume is slightly lower with the treble a tad more rolled-off. However, the device still re-connects the next time to AptX by default. On Windows 10, I am pretty much stuck using AptX.

UPDATE: I have found somewhat of a solution to this AptX crackling issue on Windows - lowering the volume of your music player (preferably below 80%) will stop the distortion from happening. Unfortunately this does not work with Android.

I have noticed my unit seems to have slightly more treble and mids on the left channel than the right one. Pressing the earcups against my ear sometimes evens out the sound suggesting it could be an issue with driver pressure, but I have run across quite a few audio products recently with poor driver matching.

In all modes, I find the loudness to be acceptable for most situations, but it is still on the low side compared to some other over-ear headphones. There is also a fair bit of audio hiss when using Bluetooth and audio is playing. One annoying quirk is that there is a volume limit in place and the loudness does not change above 60% on my devices. Dyplay has confirmed to me that they have set a volume limit, but it would have been far more practical if these scaled properly to 100%. If I want to lower the volume I have to bring my volume all the way below 60%. Note that this issue only occurs if your device has its volume synced to the headphone; activating "disabling absolute volume" or disabling "media volume sync" on Samsung devices allows you to scale the volume levels independently.

Connectivity - 9/10
As long as you are using this with one device, the Bluetooth connection is very solid. I've had next to no disconnects as long as I am near my source device. They also support multipoint connection with 2 devices at once. This is convenient if I wish to use it with both my laptop and phone without having to re-pair it each time. However, I have noticed interference if I am playing music on my laptop, while scrolling certain videos on my phone. To minimize this issue, turn the audio output device to the phone or another device when you are not using it. Also, they will constantly make a faint beep and attempt to reconnect, if I happens to be too far from my laptop while it is still awake. I had not turned off my laptop before going outside to shovel snow, only for the audio to constantly beep and reconnect.

Usability - 6.5/10
These use button controls which respond quite well. On the right side, the power button doubles as play/pause while the other two buttons can be used to change tracks or increase/decrease volume. At maximum and minimum volume, there is a voice prompt telling you of such.

Another irritating quirk is an auto-power-off feature which cannot be disabled. While this is meant to save battery life, Even when you have the headphones connected to a device, they will automatically power off after about a minute of inactivity, with the voice alert saying "power off". A small workaround for this on PC is to open a video/audio editor like FL Studio or Sony Vegas, which causes the audio to be constantly "active" and thus prevents the headphones from turning off. ANC can still be left running as it is independent of the Bluetooth switch, but I often forget to turn it off because it is on the opposing earcup. Dyplay has told me that the power-off feature is built into the chipset (QCC3005), but I could not find any further information on this. This does not happen with true wireless earbuds that use QCC chips and a number of competing ANC headphones reportedly don't have this issue.

Battery life with ANC is rather mediocre at 12 hours. For me, this translates to about 2 days of regular usage. Note that the last portion of battery will have a repeated warning and is therefore unusable (a common issue with many Bluetooth headphones). Without ANC, wireless playback is a respectable 22 hours. Although the charging speed is reasonably fast, I would have preferred if there was more battery capacity even if it meant a longer charging time. You cannot use Bluetooth while it is charging, which is a bit of a disappointment and inconvenience.

Conclusion 7.5/10
Overall, Dyplay Urban Traveller 2 has to offer for the price - decent ANC, a detailed sound and reliable Bluetooth connection, they are let down by a number of unnecessary compromises. With more budget Bluetooth headphones closing the gap with similar features (AptX, ANC and USB-C charging), it will be harder to recommend these.

Can't confirm your "results". No distortion with APTX on my headphones. ANC is very good. Sound is balanced ( no basscanons)
FYLegend

@Prutser Somehow the distortion got fixed after a few months, so it might have been a Bluetooth driver issue with both my phone and PC. I agree the ANC is great and well ahead of its price point, better than the Soundcore Q30 and 1More SonoFlow, and I prefer the sound signature to those two though I wish they were a bit less fatiguing. Unfortunately I no longer have them.

Pros: Deep bass response, good treble detail, solid Bluetooth connection, ambient sound + USB-C + wireless charging
Cons: Poor call quality, average isolation, ambient sound has many issues, boomy midbass, does not charge Type C to C
With features such as wireless charging and ambient awareness, this true wireless earbud from Jabees looks like it does it all for a very reasonable price, but does it live up to expectations?

1/19/2020 - Jabees has released a firmware update for the Firefly Pro via a mobile app. The update process is a bit confusing, the instructions say to take out the buds individually and put them back in which led them to stop playing audio. I performed the update again with the earbuds still in the case which properly updated the firmware. The review has been updated to reflect on any improvements. Unfortunately shortly thereafter I lost the buds themselves, so I can no longer give any more additional impressions.


20190807_150306.jpg
The past two years have represented a push towards budget level true wireless stereo (TWS) earbuds that have features rivaling those by mainstream brands. The Jabees Firefly Pro is an improved version of the Jabees Firefly released last year, which offered features such as USB Type C charging and ambient awareness mode. It retails for 80$ USD but with a 20% coupon it can be purchased for 64 USD from Jabees’ online store. I had previously tried the original Firefly briefly at a store while travelling and was not particularly impressed, but to be fair it was a brief session. Although I have been told by Jabees that the Firefly Pro sounds mostly the same as the original, it offers improvements in battery life and has a different charging case design that supports Qi wireless charging.

Charging Case
20190806_233109.jpg
The Jabees come in a plastic rectangular charging case that is a tad bulky, with a similar girth to the Earfun Free – battery life is rated at an additional 18 hours on top of 6 hours of the earbuds. The earbuds snap on magnetically and remain securely in place. The plastic lid is a tad flimsy, but overall the case seems quite durable. There is a large power button in the case only for doing a factory reset for the earbuds. Some odd quirks are the fact that it has 2 charging LEDs only light up turquoise and red when they are charging, and you have no telling what the charging progress (green-yellow-red) is until the turquoise left light turns off or you stop charging. I am thus perplexed by why there is a red light on the right in the first place. This is not a huge issue on its own, but it would have been nice if the lights accurately reflected battery life while they were charging, both for the earbuds and the case. Additionally, the yellow light that denotes medium battery life from 25-75% still has a green tint, which can be confusing under certain conditions.

The Firefly Pro supports Qi wireless charging and has a USB Type-C port, so it seems to be quite future-proof. Unfortunately the Type-C port only charges with a Type C to A connection, not with USB power delivery via a Type-C to Type-C cable. This seems to be a common cost-cutting measurewith many budget Type-C TWS (essentially using a USB 2.0 IC with a Type-C connector on one end), but many original Firefly users had already complained about this issue on the original Firefly, so it is unfortunate it has not been improved. As most of my mobile accessories are currently Type C to A, this is not a huge issue for me, but is not as future-proof as it could be.

20190829_005945.jpg

Wireless charging is a nice addition to the case. Like other budget TWS with this feature, there is also an issue with compatibility, with 5W wireless chargers being the most ideal. While it readily charges with my 10W ADATA charger, my 10W wireless power bank sometimes has problems initiating the charge. It is tall enough that it can be charged with my Samsung Fast Charging stand, but only if it's plugged into either a Samsung Fast Adaptive or Qualcomm QC2.0 power brick.

Battery Life
Battery life is excellent these are rated at 24 hours total playback (6 hour single use + 18 hours from the case) and last me 4-5 days with heavy usage, roughly equating these numbers in total play time. However, I have noticed what seems to be a calibration issue with the case, as it sometimes stops charging the earbuds when the LED indicator is still yellow (which designates anywhere from 25-75%). Sometimes repeatedly opening and closing the case will show red or yellow. I had one occasion where the earbuds kept showing inconsistent capacity between 40% and 70% until they were charged with the case plugged in.

Connectivity
Unlike some other TWS, these power on and attempt to connect the moment the case is opened. Pairing is reasonably quick, but isn’t much faster than TWS where they power on when taken out of the case. The music actually plays pretty early upon opening the case, but you still hear the sound to say it’s “connected” for a few seconds. The case must be snapped shut to turn off the buds. Although this is fine in practice, if the lid was to break you’d probably have trouble shutting down the earbuds, as they do not have a power-off function via the buttons. They will, however, turn off after 5 minutes of being unpaired.

Connectivity with AAC codec is rock solid – among the best I’ve experienced so far. I very rarely ever get hiccups/skips/cut-outs, although there is occasionally a faint crackle at higher volumes. Latency is not an issue for video players, but is noticeable with games as with many other TWS. SBC sounds nearly as good with the bass being slightly more boomy, b̶u̶t̶ ̶i̶s̶ ̶p̶r̶o̶n̶e̶ ̶t̶o̶ ̶c̶r̶a̶c̶k̶l̶i̶n̶g̶ ̶a̶n̶d̶ ̶d̶i̶s̶t̶o̶r̶t̶i̶o̶n̶ ̶u̶n̶l̶e̶s̶s̶ ̶a̶b̶s̶o̶l̶u̶t̶e̶ ̶v̶o̶l̶u̶m̶e̶ ̶o̶r̶ ̶m̶e̶d̶i̶a̶ ̶v̶o̶l̶u̶m̶e̶ ̶s̶y̶n̶c̶ ̶i̶s̶ ̶d̶i̶s̶a̶b̶l̶e̶d̶.̶ ̶S̶e̶e̶ ̶t̶h̶i̶s̶ ̶l̶i̶n̶k̶ ̶f̶o̶r̶ ̶h̶o̶w̶ ̶t̶o̶ ̶d̶o̶ ̶t̶h̶i̶s̶ ̶o̶n̶ ̶W̶i̶n̶d̶o̶w̶s̶ ̶1̶0̶.̶ ̶U̶n̶f̶o̶r̶t̶u̶n̶a̶t̶e̶l̶y̶ ̶i̶t̶s̶ ̶S̶B̶C̶ ̶i̶m̶p̶l̶e̶m̶e̶n̶t̶a̶t̶i̶o̶n̶ ̶i̶s̶ ̶a̶l̶s̶o̶ ̶p̶r̶o̶n̶e̶ ̶t̶o̶ ̶l̶a̶t̶e̶n̶c̶y̶ ̶w̶i̶t̶h̶ ̶Y̶o̶u̶T̶u̶b̶e̶ ̶v̶i̶d̶e̶o̶s̶ ̶a̶n̶d̶ ̶g̶a̶m̶e̶s̶ ̶o̶n̶ ̶W̶i̶n̶d̶o̶w̶s̶ ̶1̶0̶,̶ ̶a̶s̶ ̶w̶e̶l̶l̶ ̶a̶s̶ ̶o̶c̶c̶a̶s̶i̶o̶n̶a̶l̶ ̶d̶i̶s̶c̶o̶n̶n̶e̶c̶t̶s̶ ̶w̶h̶e̶n̶ ̶t̶h̶e̶ ̶s̶y̶s̶t̶e̶m̶ ̶i̶s̶ ̶u̶n̶d̶e̶r̶ ̶a̶ ̶h̶e̶a̶v̶y̶ ̶l̶o̶a̶d̶ ̶(̶t̶h̶o̶u̶g̶h̶,̶ ̶t̶h̶i̶s̶ ̶m̶a̶y̶ ̶b̶e̶ ̶t̶h̶e̶ ̶f̶a̶u̶l̶t̶ ̶o̶f̶ ̶m̶y̶ ̶P̶C̶)̶.̶ ̶D̶i̶s̶a̶b̶l̶i̶n̶g̶ ̶a̶b̶s̶o̶l̶u̶t̶e̶ ̶v̶o̶l̶u̶m̶e̶ ̶a̶l̶s̶o̶ ̶c̶a̶u̶s̶e̶s̶ ̶s̶o̶m̶e̶ ̶o̶t̶h̶e̶r̶ ̶a̶u̶d̶i̶o̶ ̶d̶e̶v̶i̶c̶e̶s̶ ̶d̶i̶p̶ ̶i̶n̶ ̶v̶o̶l̶u̶m̶e̶ ̶u̶n̶l̶e̶s̶s̶ ̶t̶h̶e̶ ̶o̶p̶t̶i̶o̶n̶ ̶i̶s̶ ̶r̶e̶-̶e̶n̶a̶b̶l̶e̶d̶,̶ ̶w̶h̶i̶c̶h̶ ̶m̶a̶k̶e̶s̶ ̶i̶t̶ ̶a̶ ̶l̶e̶s̶s̶ ̶d̶e̶s̶i̶r̶a̶b̶l̶e̶ ̶s̶o̶l̶u̶t̶i̶o̶n̶.̶

The latest firmware fixes the SBC distortion issue such that I no longer need to disable absolute volume.

Call Quality
Unfortunately, call quality is rather poor. It sounds as if the noise reduction is too excessive, with some distortion and static. When I’m commuting on a bus or train, or when a vehicle passes by, recipients have trouble hearing me.

Controls
The Jabees use physical buttons which are rather small, and overall I found the controls rather finicky. On my unit at least the right MFB button being far less clicky than the left one. After a few days, this becomes less cumbersome, but I wish the buttons were more consistent. Changing volume, which requires a button hold for several seconds, is particularly cumbersome as if you hold it too briefly (>5 seconds) it also pauses your music, but if you hold it too long, the volume will continuously increase or decrease too much. Playing and pausing can be done on both sides with a single tap, while a double tap will switch tracks. Triple-pressing the right earbud quickly will activate your device’s voice assistant. Ambient sound awareness/hear-through is activated with a fast triple-press on the left. Sometimes if you press too slowly these features will not be activated. Also note that triple-pressing when the earbuds aren't paired will change the language to Chinese.

Ambient Sound Mode
Budget TWS with this feature are few and far, so it is a nice addition to have, but you’re really getting what you pay for in terms of quality and reliability. The mic feed has some hissing and a very slight delay, and overall I find its audio quality worse than the Jabra Elite 65t, especially for wind noise. On a vehicle, there is a tendency to abruptly increase hiss or buzzing.There is a slight “sucking” sound heard when vehicles pass by or certain static noise, perhaps due to the slight delay in the mic feed and added/removed phase inversion artifacts. On a positive note it offers a more constant audio stream without affecting audio playback. Nonetheless, the ambient sound is still fairly usable for most purposes.

However, one very odd issue I experienced is that the right earbud’s mic feed cuts when exposed to direct sunlight, with an odd clunking sound heard each time I turn towards the sun and the mic feed turns on and off. As there is a narrow window that allows light to pass through, I suspect there is some interference going on since some of the internal components are visible. Another issue I’ve experienced is that the ambient sound is too loud after ending a call, if I had been using it before the call. The only solution is to re-activate ambient sound again. It remains to be seen if this occurs on other units or just mine – I̶ ̶h̶a̶v̶e̶ ̶s̶i̶n̶c̶e̶ ̶n̶o̶t̶i̶f̶i̶e̶d̶ ̶J̶a̶b̶e̶e̶s̶ ̶a̶b̶o̶u̶t̶ ̶t̶h̶i̶s̶ ̶i̶s̶s̶u̶e̶ ̶b̶u̶t̶ ̶h̶a̶v̶e̶ ̶n̶o̶t̶ ̶r̶e̶c̶e̶i̶v̶e̶d̶ ̶a̶n̶ ̶u̶p̶d̶a̶t̶e̶. The 1.4 firmware update has rectified this issue. It does, however, add a "call ended" voice prompt when you end your calls.

Comfort and Isolation
I found these to fit quite securely in my ears. Ergonomics are good but could be a bit better. Isolation with the wide-bore stock tips is mediocre. Small-bore tips can improve isolation, but even so the isolation is only average – I could still hear people talking or making coffee at the coffee shop. They also alter the sound quality such that it the bass becomes thicker. This leads me to suspect the drivers are vented just behind the nozzle. On the plus side, the Firefly Pro appears to be devoid of driver flex/ear pressure issues present in some other dynamic driver TWS, and the bass retains its clarity even in noisy conditions.

Sound quality
The Firefly Pro has a bass-heavy V-shaped sound. The sub-bass is quite deep with a further emphasis on the midbass. Although it is mostly well-controlled, the midbass can be overwhelming and bleed into the lower mids which sound recessed. As a result, vocals can sound distant in certain tracks. The treble has good presence and detail without sounding sibilant. However, there is a slight artificial, metallic tone to it, sometimes amplifying pre-existing distortion in a track, making them unforgiving of poorly mastered music, including LoFi tracks that intentionally add distortion effects. The soundstage is slightly above average, and the instrument separation is excellent outside of the lower mid region.

Channel imbalance appears to be a fairly common issue with TWS I have tried so far. Out of the box, I thought there was a bit more bass on the right bud out of the box. However, after a week of use I started noticing the left bud seemed to have clearer mids and treble – this seems to be in part due to the nozzle filter is wearing out and becoming misaligned. It is made of a stringy felt material, and thus difficult to realign without further damaging it. After further testing and the removal of the filter, this imbalance is still present, but is far less intrusive as some other TWS I have received recently.

For a basshead TWS, the Firefly Pro definitely hold their ground, while retaining good treble detail. However, look elsewhere if you want a balanced or mid-forward sound.

Conclusion
For only 80$, the Jabees Firefly Pro fulfills much of my criteria to be a daily driver – USB-C to A charging, wireless charging and ambient awareness. However, you get what you pay for in terms of quality/execution, and thus I can only recommend them with a number of reservations. They have a borderline boomy bass response, so look elsewhere if you want a more neutral sound and better noise isolation. The ambient sound feature is a great addition, but it is not a perfect implementation, and the call quality is poor.

Case Design 8.5/10
Comfort 7.5/10
Isolation 6/10
Connectivity 9/10
Call quality 4/10
Controls 5/10
Sound quality 7.8/10

Overall: 7.7/10

Comparisons with other TWS can be found in my blog post of the same review.

Pros: Deep bass for a BA driver, good comfort and isolation, wireless charging and USB type C
Cons: Limited utility, latency, prone to cutouts with AAC, SBC has more distortion, wireless charging has compatibility issues.
NOTE: This is the Bluetooth 4.2 version. Towards the end of February 2019 Astrotec has announced a 5.0 version but it was not yet available where I purchased this.

UPDATE: This review has been updated to reflect using the BT 4.2 version on the latest update of Samsung Galaxy Note 9 as of May 2019. Connectivity has been improved considerably so I can't fault Astrotec for some of these issues.

Gear tested:
Samsung Galaxy Note 9 (Exynos N960F) - AAC + SBC
Sony Xperia Z5 - SBC only
ASUS Zenbook 15 UX550GE (Intel AC 9560) - SBC

This is the second TWS earbud that I have used, after the Jabra Elite 65t. I found the Jabras to be great for utility, but their sound quality had a number of issues such as distortion and hissing on the left earbud.

Design 7/10
They use a rather generic TWS housing that is comfortable and isolates well. It looks great but isn't quite as creative as what Astrotec has done with their other IEMs. I've seen other OEM TWS that uses the exact same housing, such as the Soaiy T1S/T2 and Digihero T1, but these have dynamic rather than BA drivers and different charging cases. The shiny plastic coating around the charging case and the housings scuffs off within a rather short amount of time. After a few weeks of use, I noticed the right bud has a tendency to creak at the button, but this doesn't happen when I'm wearing them. The only major downside is it can be difficult distinguishing the left and right buds if you habitually put them on quickly.

The S60 comes in a durable charging case with a metal cap. The plastic and metal does scuff up over time but the case is quite well-built. The buds snap in magnetically for charging, but sometimes if you're too quick they won't align and charge. The connector is USB type C, which I think more TWS earbuds should be using. It's important to note that it only charges with Type C to Type A cables and not Type C to Type C. It also supports Qi Wireless charging at 5W. Unfortunately, compatibility is quite limited, as Astrotec recommends you to use 5W chargers. It works fine with my 10W wireless power bank, but for some other 10W charging pads I get a charging error. I also suspect the metal cap might trigger foreign object detection. Charging speed either way is reasonable (~1.5 hours to fully charge from approximately 25%) but I wish it supported fast charging.

ADATA CW0100 (10W) - Charging error regardless of power brick used
J5Create JUPW1101 Wireless Charging Pad (10W) - Fails to charge if plugged in to QC 2.0 or 3.0 charger. Fully functional when plugged into PC's USB 3.1 port.
Mycell MY-PC-035 Wireless Power Bank (10W) - Charges but gets very hot, especially if both the case and the buds are out of battery.

Utility 5/10
At this price point, TWS earbuds tend to be not as usable as pricier counterparts. Controls are limited to play/pause, next/previous tracks. I would have liked to see volume control (added to the Bluetooth 5.0 version) and ambient sound mode.

Call quality seems mediocre as the other side couldn't hear me clearly when I was on the bus or train.

Sound (updated impressions) 8/10
These have Knowles balanced armature drivers and have a rather warm and bassy sound. Highs are a tad rolled off while mids have reasonable clarity. The bass is quite powerful for a BA driver and you get a fairly wide soundstage with good detail retrieval. However, this is somewhat cut short by distortion that occurs with certain bass notes. Using SBC, the sound signature is largely retained, but the sound is more prone to distortion, particularly in the left driver. Both AAC and SBC exhibit some degree of hiss and clicking EMI on the left bud, albeit less severe than the Jabra 65t. On the Galaxy Note 9, the volume output is rather low, unless you go into Bluetooth settings and turn "Media Volume Sync" off and on again. This greatly increases the volume and still sounds great for AAC, but SBC becomes more badly distorted at the higher volumes. On my ASUS Zenbook 15, SBC seems to sound cleaner at higher volumes than the Note 9.

vs. Jabra Elite 65t - The Jabras are a brighter-sounding IEM and prone to sealing issues for my ears. Although I find the bass decent most of the time, they have a tendency to sound rolled off during transit.

vs. ATH-IM70. The sound is rather similar between the S60 and the IM70 in that both have an "organic" tuning that gives a lush yet reasonably detailed sound. Where they do differ is that the IM70 has more midrange emphasis, while the S60 has better detail retrieval.

Connectivity (Updated) 6.5/10
SBC connection is very reliable, and I very rarely get any sound skipping or cutouts. With the Galaxy Note 9, AAC connectivity is not very reliable. Before there was a tendency for the audio to skip every 4-5 minutes. but after the May update the connectivity has improved greatly but it still might stutter after about 15 minutes of playback, although I've had longer train rides where there's been next to no stutter. After it stutters there is sometimes a slight desync and volume imbalance between the left and right channels giving a fake stereo effect. It is definitely not a defective unit as I was able to try another pair at the store which exhibited the same behaviour. I briefly tried it with the seller's iPhone to which I noticed no connectivity issues using AAC. Connection is also quite stable using my laptop, with VERY occasional cut outs (seems to be related to the laptop itself). Regardless what codec you use there is also considerable latency. This is to be expected with TWS buds, but it is noticeably more than the Jabra Elite 65t.

Conclusion
The S60 has such high potential for its sub-100$ price point, but falls short in its utility and connectivity issues, especially on Android. Perhaps it's better to get the Bluetooth 5.0 version or wait for Astrotec's next upcoming TWS.

1000+ Head-Fier
Pros: More lean and transparent than the 3590, well-controlled bass, nice aesthetics
Cons: Sibilant and fatiguing, smaller soundstage than SHE3590
NOTE: This review is on the SHE3900
 
The Philips SHE3900 is a budget level IEM that represents a spiritual successor to the SHE3590, which was regarded as one of the best. The SHE3905 is a variant with an in-line remote and microphone for mobile devices. Aesthetically, it takes the 3590 to a new level, but is it an improvement in sound quality?
 

Build quality

Let’s start out with the bad news. The main disappointment I have with the 3900 is that its cable quality is nearly identical to the 3590, and therefore just as microphonic. This time they did include a cable cinch that can be detached on the left side. Philips has been doing this in their recent IEMs, claiming this can be used for preventing tangles by putting the other end of the cable in the notch. While I can’t really see the advantage of this, sometimes I prefer snapping it off because the cinch is a bit hard to move up and down.
 
The housings are the most significant change from the 3590. They are simplistic but eye-catching and highly reflective in direct sunlight. One downside with the new housings is that they are slightly triangular shaped – this makes over-ear fit a bit less comfortable than cable down (although it is no big deal).
 
Finally, Philips has decided to put a gold-plated, right-angle plug on this IEM. It feels more durable but the plug’s coating is a rubbery material that's suspect to fingernail marks.
 
7.5/10
 

Isolation and comfort

With cable down, isolation is considerably better than the 3590 thanks to a more reliable seal. I'd say the isolation is slightly above average but they still let some sound in. However, I did notice they do exert a little bit of pressure on my ears, and shoving them in further causes driver flex and a more congested sound. These are quite comfortable worn halfway inserted in your ear.
Isolation: 7.7/10
Comfort: 8/10 (cable down)
 
[size=24.57px]Sound quality[/size]
These impressions are primarily based on using the Fiio E10K. Like the 3590 they require a bit more volume to drive, despite the low impedance and high sensitivity.
 
These have a similar v-shaped sound signature to the 3590, but somewhat colder and leaner. The treble is more emphasized, and can be sibilant or grainy on poorly mastered tracks. Therefore I would not recommend the 3900 for EDM or house tracks where the highs can be fatiguing. For example Avicii’s new album Stories sounds very sibilant at high volumes (especially “Waiting for Love” and “True Believer”). On the other hand, the 3900 brings out the life in Daft Punk’s Random Access Memories, which may sound rolled-off or laid-back with other IEMs. The bass is tight and fairly deep, with little mid-bass bloat. The midrange on both is recessed, except the 3900 has a bit more forwardness at the top but sounds papery at times.
 
The soundstage is average for an IEM. It is somewhat intimate without sounding congested, but is lacking a bit in reverb or decay. I'd say the soundstage is similar to the Audio-Technica ATH-M50x but lacks depth.
 
Eartip selection: Audio-Technica CKM eartips were preferred for better isolation and comfort as well as a slightly warmer sound with the highs tamed down slightly, though they can still be sibilant.
 
7.5/10
 
Filter mod: Unlike the 3590, there is no additional foam behind the mesh filter, and this may be why the treble is so bright. For this mod, take a needle to take off the filter (note the backside has an adhesive encircling filter paper) and then put some foam behind. If you do this mod and still use the stock tips you won’t notice much of a difference but it is a decent improvement from stock if you’re using Audio-Technica eartips.
 

Vs. Philips SHE3590

the 3900 sounds like a more intimate, leaner yet aggressive version of the 3590, which is warmer and slightly more laid-back in comparison. The 3590’s highs are slightly smoother and less fatiguing, while the 3900 is more detailed but at the cost of sibilance. Overall, the 3590’s soundstage is wider and deeper, having considerably more decay. If you are sensitive to sibilance I wouldn’t recommend either IEM.
 
[size=17.03px]Vs.[/size][size=17.03px] Philips SHE8100[/size]
This is one of Philips' newer IEMs with a more compact aluminum housing and differently tuned drivers. Although its treble detail is more transparent than either the 3590 or 3900, and its soundstage is a bit deeper, its midrange is more recessed and overall this is a more extreme v-shape sound than either of those IEMs. It’s a real shame about the mids because these could have been a reasonable option otherwise.

 

Vs Xiaomi Piston 3

These are essentially a polar opposite to the Philips. They are warmer with more midbass. Overall it is more punchy but not as deep in the bass as any of these Philips. Treble and midrange is somewhat muffled, lacking much sharpness. Although the soundstage is wider and deeper, this hazy top end makes it sound rather congested at times. That said, after listening to the fatiguing highs of the 3900, these are quite pleasant and more immersive. If you are looking for a more “balanced” top end and don’t mind a slightly boomy midbass, these would be a more ideal choice.
 

Conclusion

I have somewhat mixed reactions about the 3900 and can only recommend them with reservations. They perform well for the price but aesthetics aside the 3900 is more of a sidegrade to the 3590. I would recommend you stay away from these if you are sensitive to sibilance or are looking for a warmer sound and larger soundstage.

1000+ Head-Fier
Pros: Sharp, transparent treble, powerful yet balanced bass, good comfort and isolation
Cons: Mids are quite recessed and thin, requires lots of volume for best sound.
In this review I will be taking a look at one of Philips newer IEMs, the SHE8100. The Philips SH3580/3590 has been regarded as one of the best budget in-ear monitors, so I will be comparing the 8100 to it. I bought these for around 18$ CAD at Best Buy. I was considering buying the SHE3900 instead, which was around 15$, but the 8100 seemed like a newer and slightly higher-end product. 

Build Quality

The SHE8100 is overall a level up from the 3590 in design. The housings are aluminum and quite aesthetically pleasing. The black one actually reflects a deep bronze-black. The only thing that detracts from the aesthetics is the large L/R indicators which look somewhat kiddy, though thankfully they face towards you so you easily know which side is which (in the 3590s they face away from you). 
 
The cable quality is about the same as the 3590 – thin and springy. Thankfully there is now a cable cinch, albeit an oddly designed one. The left side is notched open, so you can take out the left cable. This allows the cinch to be attached to the other end of the cable for better storage, though I don’t really think it’s helpful for preventing tangles. These have a gold-plated right-angle plug, compared to the flimsy chrome-plated straight plug of the 3590. It is well-built but I have noticed a small lump within the plug shortly after first use. 

Isolation and Comfort

Isolation is excellent, despite the air vents at the back of the housing. You can still hear train/bus noises but conversations become almost inaudible. I get some driver flex on the left ear if I insert the housing too deep, but these IEMs still seal nicely just slightly on the ear. I don’t know if the drive flex is just my unit or if it’s common. Like the 3590 these have oval nozzles, which helps with the comfort. Overall I find these quite comfortable and lightweight despite being aluminum. These also fit very nicely over the ear but then driver flex is more likely to occur.

Sound quality

I gave these about a week of burn-in, but as with the 3590, there isn't much of a change in the sound as out of the box; maybe slightly warmer but not a huge change.
 
These have a lean, V-shaped sound signature.  They require a considerable amount of power to drive at a good volume, despite having an impedance of 16 ohms and sensitivity of 107 dB. The bass is deep but quite balanced. Neither the mid-bass nor the sub-bass seem to bloat out, but like the 3590 more volume is needed to really feel the bass. Unfortunately the midrange is the greatest disappointment - it is recessed, distant and thin, especially with male vocals and drums. The highs extend well and are quick and sharp, but some listeners may find it sibilant. Instrument separation is quite good but is biased towards the highs; elements in the midrange are greatly compromised. Soundstage is fairly wide and rather deep, but has a sense of intimacy (think ATH-M50x). I don't find the soundstage to be very congested.
 
I MIGHT consider removing the metal filters, but I am concerned this will only further emphasize the treble.

Conclusion

These have a lean, detailed sound and good bass for a budget level IEM, but the lack of a solid midrange is a big disappointment. If you already consider the SHE3590 to have recessed mids, you’ll hate these. The 3590 sounds bloated in the mid-bass and warmer in comparison. While the bass and treble sound better-controlled in the 8100, the 3590 is a better all-rounder. It's a real shame because the 8100 is a step up from the 3590 in terms of design and isolation. Also consider looking at the SHE3900, a successor to the 3590 released last year. Perhaps I should have got that instead...

It seems to have been released in Japan already but I haven't seen any info on a worldwide release. Not sure if it would really be a huge difference from the 8100 - from its specifications it too has 8.6mm drivers and its frequency response isn't as wide. Many of the 8XXX and 9XXX series have 8.6mm drivers (the ones for the 8100 were claimed to be "re-engineered").
 
Any cheap Philips with more forward mids?
FYLegend
FYLegend
Also, I removed the filters and instantly regretted it - became even more sibilant and no improvement in mids. Fortunately the filters have quite a sticky adhesive and can be stuck back on.

I just saw some reviews of the 9720 and the users who have reviewed it so far are disappointed. It has been described variously as thin, bass-light, and the treble either being prominent or not detailed enough.
 
Bought the 3900 last week. Mids are a lot better than the 8100 but their soundstage is smaller than the 8100 and 3590, and they don't sound as warm as the 3590.

1000+ Head-Fier
Pros: Great aesthetics and build quality, excellent instrument separation, balanced mids and highs with no sibilance
Cons: Poor isolation, soundstage a bit congested, highs and mids are hazy and distant lacking sharpness, poor stock eartips
I bought these on Geekbuying after a considerable price drop to about $16 USD. Having missed out on the hype for the Piston 2, I decided to pick up the Piston 3 instead. The other bang-for-buck IEM I own is the Phillips SHE3590.
 

Design

The Piston 3 has a very stylish design, but is more typical of an IEM and unfortunately don’t stand out as much as the bullet-like aluminum housings of the Piston 2. The cable is fairly well built, though from the Y-splitter up they are rubberized and a tad bit microphonic. It doesn’t bother me much, but the inline remote box does worsen microphonics. It is placed too high and sometimes hard to feel where the buttons are. Please note that the in-line remote only fully works on Android devices, while the middle button can be used for iOS devices. On my HTC phone, the side buttons are for next/previous track but on some other devices they are volume buttons. The Kevlar coating from the splitter down is quite durable but are tangle-prone and I think it may splinter over time. That said, I wish the entire cable was Kevlar rather than the bottom section as it seems to be less microphonic down there. With these small issues aside, the build quality is excellent.
9/10

Comfort

The eartips that came with the headphone were of rather poor quality. They have a matte finish and are prone to collecting dust. The stock tips give a bit more edge to the treble and a more intimate soundstage, but while comfortable they feel loose in my ears and I had a hard time getting a good seal. I found both Audio-Technica CK and Phillips SHE3590 tips have a more secure fit. The SHE3590 tips are a bit harder than the AT tips, don't seal as well and a bit less comfortable. Over-ear fit is possible and greatly reduces microphonics, but the fit is a bit uncomfortable and may also prevent a good seal with some eartips.
8.5/10

Isolation

The Piston 2 was not the best headphone for noise isolation, and unfortunately the Piston 3 doesn’t fare any better. It has a few air vents in the housing which give it a semi-open design. Though this is intended to expand the soundstage, it means the isolation is poor and sound leakage is quite high, even if you use different eartips. The leakage isn't noticeable on a loud bus or train but can be quite noticeable in silence. Of all the IEMs I have owned so far (many of which have such air vents), these have leaked the most sound. They aren’t as bad as earbuds in terms of isolation, but for an IEM they are rather poor.
5/10
 

Sound

NOTE: Phillips SHE3590 tips mainly used to evaluate the sound quality. A week of burn-in overnight was given before final impressions. I think the bass is a bit punchier and the mids a bit cleaner after burn-in.
Overall I would consider the Piston 3 to have a warm, laid-back and slightly v-shaped sound signature. The bass is punchy, with an emphasis on the mid-bass, which can be a tad bit bloated, and a bit “detached” from other frequencies. However, the bass is very well-controlled most of the time and you do get a decent thump from the sub-bass. The midrange is relatively clean and flat, but there is a relatively subtle and broad peak from the upper mids to the lower highs. This gives a subtle metallic texture to the mids as well as the treble. However, both the mids and treble sound distant and lack sharpness. Although I get an impression the treble extends with a peak, it just seems confusing at times.
 
With the stock eartips, the soundstage is rather intimate, while Audio-Technica and Phillips SHE3590 tips give a bit more space. The SHE3590 tips give a bit more edge to the treble, though they don't seal as well as Audio-Technica tips. As a result, the soundstage slightly above average.  It has a fair amount of width and depth. However, even though the overall sound signature is by no means aggressive, the soundstage is sometimes congested. It just feels like there’s too much going on. Instrument separation is excellent, so I sometimes pick up something I haven't with other headphones. However, the individual elements tend to lack focus or precision; as noted earlier they can be hazy and distant. They are also quite unforgiving of low bitrates where compression becomes quite obvious.
 
For an IEM designed for portable use, these are a bit harder to drive than other IEMs at the same price as they have 32 ohms of impedance and 98 dB sensitivity. On my phone (HTC Butterfly s) I find myself having to turn up one or two volume steps than my other IEMs for a good listening volume. On the positive side, they don’t hiss as much as most other IEMs.
 
I can see why people who want a more balanced signature will like the Pistons’ sound, especially those sensitive to sibilance. They are quite versatile for different genres, but I found them a bit “hazy” and lacking air. Overall, I don't think the sound is worth the compromise in isolation.
 
Filter mod:
Removing the metal filters increases the edge on the upper-most mids and some sibilance may occur. I would not recommend doing this if you are sensitive to sibilance. Treble, while a tad bit more airy, is still not well-defined. Also note that this mod is irreversible unless you find a way to glue back the filters and fold them back into their original shape.
 
7.9/10
 
vs. Phillips SHE3590
The SHE3590 is the other budget level IEM that I have which has a similar bang-for-buck reputation. Compared to the Pistons, the SHE3590 has a much sharper v-shape signature and a considerably wider, more immersive soundstage. The treble is much brighter and crisp in the highs than the Pistons. Although they are ideal if you are after a detailed sound, they may be too sibilant, and are also lacking in the mids. Their build quality is also quite cheap.
 

Conclusion

The Piston 3 is a great bang-for-buck IEM for those who want balanced mids and highs without sibilance or harshness. However, it is important to note sound signature isn't for everyone. If you are looking for something with more crisp mids and highs or an immersive sound, you will be disappointed. I would also advise looking elsewhere if you want good isolation.

Nicely written, but I can't say I agree with all your cons except for the tips and isolation.
The initial "congested sound" or "haziness" and so on clear up greatly after long burn in.
It is a long burn in but once you get there everything clears up so much it's a different iem compared to straight out of the box. You should really give them another shot.
Cheers.

Thanks for the reply. I've given these over a month of use already and they aren't as congested or hazy as they used to be, but I think in the end it still boils down to personal taste - I just think there's something lacking about the texture of the mids and treble over what I'm accustomed to. If I do see a change some time I will update this review.

True, if there are people who like the sound of T-Peos and such other IEMs, I would also say that these Pistons relatively lack a little sparkle or the texture. I thought they were fine but I don't have experience at this price range except for these so maybe I should try some more :)
Cheers.

Pros: Versatile, great mids and bass, excellent battery life and can be used as a power bank
Cons: DSP issues on some devices at low volume, can get laggy with some devices, thick treble texture, micro-USB port breaks over time
I bought this speaker at Target before it closed, getting a decent discount (it was on sale plus I got a coupon for it). I wanted something more convenient for listening to music while studying, as using headphones can be a bit distracting and tedious to put on and off.
 
Design
The Charge 2 looks a bit like a giant soda can or battery (that's what it is), the build quality of the speaker itself is quite durable. Unfortunately there is no carrying case and the bass radiators appear vulnerable. The speaker is also rather prone to rolling around. The rubber ring on one side of the speaker is vulnerable to coming off, but I could just glue it back.
 
Battery life is excellent (I get around 10-12 hours) and it can also be used as a 6000 mAh power bank. (I haven't used it often enough to give a good impression though) You can also use the speaker wired (you will need to buy an auxiliary cable yourself), but it still uses the battery and can't be charged by USB fast enough to work continuously. 
 
Sound
These have a bassy yet mid-forward sound, and can be quite loud for a small room. The sub-bass is quite powerful, though it is sometimes a bit "bouncy" and seems rolled off at the very lowest region. One problem I have noticed is sometimes the sub-bass seems to fade or mute out - this is noticeable in some tracks where it is relatively low. A good example of this is Daft Punk's Doin' It Right, when the synth comes in during the middle of the song - the sub-bass should be there but instead it fades out relatively quickly. The mids are quite forward and sound very crisp and refined- something I did not expect with a bluetooth speaker like this. Therefore, vocals sound excellent with the Charge 2. The highs are a bit splashy and thick, but not sibilant. Stereo separation is present but quite narrow, though given the size and portability of these speakers, that's to be expected. Unfortunately the Charge 2 can't be paired with a second unit for better stereo like the UE Boom.
 
Overall the Charge 2 has a fun, bassy sound signature that still works great with vocals. It is quite versatile but shines the most with more upbeat tracks.
 
The UE Boom is the closest competitor I can think of. I don't own it or have head it enough to give a good impression, but trying it out at the Apple Store and listening to some demo videos online (which compared it to the Charge 2), it seems to be lacking in bass and has a more treble-forward sound. The advantages it has over the Charge 2 are that it is louder, splashproof and can be paired with a second unit for wider stereo. The JBL Charge 2+, which was released last month, is splashproof.
 
Potential issues
Unfortunately, one issue to look out for with the Charge 2 is sound distortion at low volumes. There's a tad bit of buzzing sound and the highs sound distorted. Some reviewers have noted it is especially bad in early units of the Charge 2 and later users claimed that this was rectified to some extent. Later units have volume buttons that are synchronized to that of a connected iOS device (no difference on Android or other devices). I can confirm I have the later version. On my laptop I notice a bit of DSP distortion even at higher volumes, but it isn't as present when I use my phone or iPad (both fine at mid to high volumes), so I believe it may also depend on the device hardware and/or software. Another downside is that after a long period of silence, the Charge 2 sometimes doesn't play the first second or so of music - you need to keep it constantly "active". It also seems to lag a split-second after prolonged use on my laptop.
 
Final impressions
For a mid-100$ Bluetooth speaker, the Charge 2 is well-built speaker that has a relatively versatile sound signature. However, a few potential issues, such as the DSP distortion could be dealbreakers.
 
UPDATE: Sadly, the microUSB port broke in about a year and a half from purchase. Unless I bend the cable slightly and let it stay in that position, the device can't charge. As this problem has been reported in the original JBL Charge and Flip series it suggests they did not address the problem. For this I am taking off half a star... :frowning2:

Pros: Fun sound for the price, decent highs with lots of shimmer, good soundstage, lightweight yet durable
Cons: Recessed mids, rolled-off bass, highs may be too bright for some, earpads and headband wear out over time.
These were my first over-ear headphones, and I read a lot of good things about these headphones before buying them. I got them for 40$ (Canadian) at Future Shop as they were on clearance. I've used it for about 2 years before I upgraded to the Audio-Technica ATH-M50x.
 
Design
Despite their looks, they are quite durable and aren't prone to breaking. The retro aesthetic is also very nice.
 
The downsides in the design are to be expected in a headphone at this price. The earpads and headband do wear out over time and the headband isn't replaceable. The earpads can be replaced but as far as I know new earpads are only sold on AliExpress.
 
8/10
 
Comfort
These do get a bit hot after prolonged use, especially in the summer time, they are decent earmuffs in the winter though they do leak tiny bit of air inside (you can hear air going into the housing when you walk around, but it doesn't really get in)'. The clamping force is moderate and they have considerable space around the ears. I found these more comfortable than my ATH-M50x.
8.5/10
 
Sound quality
Note: These are based on an unmodded unit.
These have a v-shape sound signature that is "fun" and lively. The bass is decent but slightly rolled off at the very bottom, so while there is a considerable amount of sub-bass, it doesn't reach very deep and there is a bit more mid-bass. The impact is blunt and can be a bit muddy at times. The mids are recessed and there is a somewhat "hollow" reverb, but they don't sound dry but a tad bit warm.  The highs are probably the best part of the sound signature, the treble extends well and has a lot of shimmer. Some listeners might find it too bright but I really enjoyed this sound as it does bring out some details, especially with guitars. They don't sound particularly sibilant, however, as the treble peak is rather wide and not short and shrill.
 
These are fine with portable gear, though the volume is about a stop less than my IEMs. The subbass does pulse a bit more when using a device with amplification.
 
For the price, the soundstage and instrument separation are decent. While they do struggle to resolve some details, they don't sound congested.The M50x has a slightly smaller soundstage but definitely wins out in instrument separation.
7.5/10
 
Value
For under 50$, these are a very good deal if you want a portable, lightweight headphone with a fun and lively sound signature.

Pros: Deep, powerful sub-bass, warm lower mids, large and immersive soundstage
Cons: Mid-bass can be a tad bloated, slightly recessed upper mids, microphonic cable, sibilance with some eartips
I bought these last summer during a visit to Taiwan. I had hoped to buy a replacement Audio-Technica CKM500 (which broke) but they have been replaced with the CKR5 which are a bit of a let-down with its bloated bass and congested soundstage. After trying out various headphones, the salesperson suggested the AH-C560, a mid-range Denon IEM released in 2010. Although they have been considered "discontinued" in some areas, they are still commonly sold in headphone stores in Taiwan.
 
Many reviews online are on the mic'd version the AH-C560R and while praising the sound quality its mic placement has been criticized which is something to watch out for.
 
Design:
Aesthetically, these are really simple but nice-looking headphones. The black one looks more or less typical, but I have the silver version which does stand out nicely. The term "hybrid "denotes the housing material, not the driver's design (these are dynamic drivers). Denon calls them "hybrid" because they use a mix of aluminum and resin in their housings, which Denon claims will reduce vibration interference and improve clarity. I’m not sure entirely how accurate this claim is, as the cable is quite microphonic, but the housings are quite durable, save for the strain reliefs, which are made from long tubes of hard plastic. While it feels durable and they haven’t snapped (yet), it is something to watch out for.
 
The biggest downside of the design is the cable. The cable is made of a rubbery plastic material that, while durable, is prone to tangles. In fact, the cable can become iced-solid being more easily kinked when it is cold. From the Y-splitter up to the housings without a cinch or clip, the cord is rather microphonic so they’re better off worn over the ear or using the clip. There is a cable cinch but it easily gets loose when you walk around. The cable is also 1.3m long, which may or may not be a disadvantage. I prefer a slight bit of length to the cable as the cable is less likely to be strained if it’s caught somewhere. This cable is very similar to that of the Audio-Technica IM70/IM50, though these IEMs have a over-ear fit (but I still found them a bit microphonic for an over-ear IEM)

Comfort
Denon's stock eartips are very similar to Audio-Technica’s and they are fully interchangeable with them as well.  Denon's are slightly more bulbous in shape and more durable. They don’t insert deep into your ears but are quite comfortable and I find myself wearing these for a long time. They tend to sit out the ear feeling slightly loose but aren’t likely to fall out of your ears so easily. As AT’s tips are a bit thinner they can fit into your ears a bit but give a slightly more laid-back sound. Wide-bore tips are most ideal if you want the most sub-bass and the widest soundstage, but it comes at the compromise of harsher highs - Phillips SH3590 tips are a better option, balancing between the tradeoffs.
 
Also included is a pair of Comply eartips. These isolate pretty well though they do make the highs a tad veiled.
 
8.5/10
 
Isolation
These are a "semi-open" in-ear headphone, as they have some small air vents on each side and don't fit very deep. This does help with the soundstage but does mean that isolation is somewhat lacking, I would say about the same level as the CKM500, though the design of the housing means you can put them in your ear a bit more with some tips. On medium to high volumes, they are fine for commuting. Comply eartips do help a bit, but they also change the sound signature, give a smoother, veiled sound.
 
6.5/10
 
Sound
I did not burn these in specifically but rather gradually with a month’s use. The bass was rather loose at first but has become tighter since then. They have rather high sensitivity and are easy to drive, so you’ll get a lot of volume with these. I don't consider myself an expert but these are my own impressions on the sound quality:
 
The bass impact is powerful but a tad blunt, but not sloppy or loose - fluid or smooth is the best way to describe it. The sub-bass and mid-bass are both elevated considerably, but they usually don’t distract from the rest of the frequency range. Overall the mids are smooth and warm, the lower mids being more forward and the upper mids a tad bit recessed. Overall, vocals sound a bit warm and dark with these, though male vocals can be a bit thin. Doin' It Right by Daft Punk is one particular track that shines with these. There is a slight treble peak has a slightly rough but sharp texture that adds some sparkle and extension, but I overall didn’t find these sibilant using stock or Audio-Technica eartips. Wide-bore tips expand the soundstage but also make the highs sound more sibilant.
 
The soundstage is quite wide for an IEM, thanks to the air vents, although depth and height are average. The instrument separation is good overall, but though the lower mid hump occasionally causes some parts to be drowned out a bit a higher volumes.
 
To conclude, these are excellent sounding IEMs despite being released in 2010. They are far from neutral but definitely excel in a wide variety of genres.. They work well for pop or R&B but are still competent for classical and jazz.
 
Despite the slight difference I felt the Denon tips gave me a bit better treble extension while the Audio-Technica tips give a slightly more rolled-off treble (the core is harder in the Denon tips). Phillips SHE3590 tips also fit and they give a somewhat thicker sound, a bit like the CKM500. Wide-bore tips greatly increases the soundstage height (and the depth to a lesser extent) and brings out the upper mids a bit more. The treble also sounds thicker. There is a tad bit of sibilance as the treble peak becomes apparent, but despite this compromise I would still recommend using wide-bore tips if you want to get the most out of the soundstage.
 
Compared to the CKM500, I was struck by how similar the two are as they are both bass-heavy but similarly detailed. The CKM500 has a more distinct treble peak and its soundstage is not as wide; both have a mid-bass hump but the Denons have more sub-bass. The Audio-Technica IM70 has a similar soundstage to the AHC560, but has less sub-bass and a more mid-forward sound.
 
8.1/10
 
Value
Given that they aren’t widely known and have been discontinued in North America, the price unfortunately hasn’t changed much since their launch. The technology and design is from almost 5 years ago, but the sound quality still excels. Although the cable design leaves something to be desired, these are still a great basshead IEM for the sub-100$ price point.

Pros: Massive bass impact and good treble extension, soundstage and instrument separation surprisingly good
Cons: Coloured sound, bloated bass, terrible microphonics, flimsy plug, housings easily broken
These cans come free with HTC phones released in the past year. This version, known as the MAX300 in China, can be found online for under $15 (as far as I know, they're not sold on most of HTC's online stores except China or Taiwan). There are also Bluetooth and three-button in-line versions being sold officially on HTC's site.
 
Design
The design is reminiscent of Beats headphones. They look good if you put Beats Logo stickers on the side. (...)
 
Isolation is very good, better than my CKM500, but due to the design of the driver housing, inserting them into your ear gives off a "squeaky" or "sucking" sound while music is playing. I tried my CKM500 tips and they still do this, so it may be a case of driver flex or air pressure building up on the eartip being pressed back. Putting them into your ears may hurt a bit if you're sensitive to pressure but the fit is generally quite comfortable.
 
The cable is flat and does not tangle very easily, but it is VERY microphonic; even wearing over-ear (which is awkward because the button controller on the right cord is now right beside your chin). Wear with a clip if you have one. Additionally, the plug is very flimsy and with my phone it likes to be "half-plugged" thus removing the vocals.
 
Sound quality
Note that these are my impressions from a few months of use, without burn-in as these are not the headphones I regularly use.
 
At first I was somewhat turned off by the sound. The bass is way too heavy. The sound signature is very coloured and they are sometimes likened to an unbranded Beats. These are definitely bass-heavy and the bass impact is very good. However, at the same time, the bass can be bloated and muddy. They are not ideal for bass-heavy tracks but they do give more life to tracks that lack bass. The mids aren't dry or recessed, and have a slight bit of warmth, but they are slightly veiled and may sometimes be drowned out by the bass. The treble is a tad thin but seems to extend very well. Although there is some occasional sibilance it doesn't sound harsh, and separates very well. The soundstage is quite good; it is quite wide, though it is more average in depth. There's quite a bit of layering and I sometimes pick up new details that I don't notice with some of my other headphones. In fact, I find myself listening to these cans more and more. To conclude, the MAX300 is far from balanced, it serves the bassheads well, without sacrificing the highs or soundstage.
 
Overall
For under 15$ these are not a bad deal. They can't compete with Sony and LG's options. However, except for the bloated bass and the awful microphonics, I was rather impressed with these cans considering the price. The are not for audiophiles but may be good for bassheads who would like a bit of detail and soundstage.
 
Update: One of the cans broke. The build quality is a big problem unfortunately.

This one is known as HTC Max300. A newer version is Max301 but I don't know if there is any improvement in the build quality. I agree with you that the separation and sound stage are excellent.  I love the isolation and do notice the suction pop sound each time I pulled them out from my ears. It is very light and totally "disappear" in my ears. Yes, the cable microphonic is there but not as bad as Sony MH1.  I don't find the bass bloated though maybe I am a bass head.

Thanks for the reply, how does their sound compare with the MH1?

MH1 is much darker compared to Max300. I personally prefer warmer sound, so Max300 is no doubt my preferred choice over MH1.  Max300 also has the cable microphonic issue but it is not as bad as in MH1.  By the way,  MH1 also have some sibilance issue so I find MH1 very difficult to love.

Pros: Styling and comfort, tangle-free cord, detailed treble with very little sibilance, decent amount of sub-bass, great isolation (with other eartips)
Cons: Microphonic and springy cable, congested soundstage, recessed mids and mid-bass
The CK323M is a Japan-only budget IEM from Audio-Technica. There is also a version with an in-line mic and controls, the CK323i. The CK323iS appears to be a version that is compatible with Android and has a switch on the side. When my CKM500 broke during a flight to a transfer stop to Japan, I bought this IEM at the airport store for around 20$ USD. I knew it wouldn't sound as good as the CKM500 but hoped it would at least have some good sound coming from Audio-Technica.
 
Design and Comfort
These are some of the best-looking headphones by Audio-Technica.  They come in many different colours though I like the red one. The cord is semi-flat and not prone to tangles (CKM500's cord tangles quite a bit in my pocket), but at the same time it's springy and makes a lot of noise while moving around unless a clip is used. There is a cinch, but only when it's moved just below your chin will it reduce some of the microphonics.
 
They are also quite durable - I've had them survive several laundry washes in my pockets.
 
Sound Quality
Out of the box, the sound signature was a sharp V-shape with emphasis on the highs. They were a bit bright but otherwise sounded detailed, and not much sibilance at all. I actually prefer this type of sound to that of the CKM500 which has a rather thick-sounding treble. The deep low end is also noticeable but unfortunately the bass lacks definition and the mids are deeply recessed and lack warmth. Burning them in helped tone down the treble and boost the mids a bit but the overall sound quality still sounds dry, there is also a considerable amount of sub-bass now. However, the bass is still muddy and bloated, lacking the definition of the CKM500 - the midbass still sounds recessed as with the lower mids. The soundstage is rather small on these cans (similar to the CKM500 but a bit more congested) and instrument separation is passable. They are forgiving of harsh highs and not as good for vocals or bassy music. A bit of EQ can add a bit of the warmth to the sound though. Dare I say, these are one of the few headphones that I prefer with Beats Audio EQ on my HTC smartphone, as it does boost the mid-bass and sub-bass considerably.
 
FILTER MOD: Taking out the filters makes them overly bright, though this can be relieved with some foam (eg from cheapo earpads). As a result there is a bit more shimmer in the highs and more sub-bass, approaching the signature of the ATH-M50x but the mid-bass is still very muddy.
 
Isolation
The CK323M is a half-in-ear design like other CKM headphones, which provides decent isolation but is not the best for very noisy environments. It uses the same eartips as the CKM500, so the isolation with the stock tips is about the same, though it can fit in your ear just a tad deeper due to the driver design (the CKM500 has a disk-shape preventing the earpiece from going in as much). The CKM500 has air vents on the outside of the housing, while the CK323M has air vents in the nozzle. Because this region is covered by the eartip, they don't really help with pressure or the soundstage.
Phillips SHE3590's tips significantly improve the isolation, so much the cans "suck" into your ears - the best isolation out of all my IEMs so far.
 
I do not recommend these for sports because they have quite a bit of cable noise, although it does come with a clip/cord manager. They are also extremely awkward to wear over the ear. (I actually lost the clip but I didn't find them useful, they do reduce cable noise but due to the springy cord, it's hard to actually wrap the cord around it)
 
Value
You're mainly buying these for the looks and I think they are the most stylish IEM made by Audio-Technica so far. Unfortunately, the sound quality can be deal-breaker here. They aren't the worst sounding at this price but there are better options. Perhaps my expectations were too high coming from the CKM500. I do think the Phillips SHE3580 and the Xiaomi Piston 3 are better options at this price.

Have you guys tried switching to bigger tips? I find the bass is reliant upon the correct fit. With the right fit these sound great for the price.
 
Some hi-res "Fleetwood Mac-Rumours" from an Audioengine D1 putting out to an Audio Technica AT-HA22TUBE desktop amp, and these sound fantastically close (under the same setup) to other ubiquitously-lauded IEM models such as the Zero Audio Carbo Tenore, which costs approximately four times the price.

I agree they are not terrible, perhaps I was a bit too harsh in the review (needs a bit of an overhaul), as it was largely based on them in the first few months without modding or different tips; the cable is more put-off than the sound. I loved the styling (reminds me of Sennheiser's recent CX and Momentum in-ears). They have quite a bit of sub-bass after burn in and the filter-foam mod I described above. I don't usually mind slightly recessed mids (like the M50) but I thought these were a bit muddy in the mids and mid-bass. The treble is very clean and not sibilant. In the end they sound like the M50, but a bit more muddy and less extension in the highs. The IM70 has a much more "lush" sound but unfortunately mine seems a bit broken. (right housing doesn't sound as punchy as the left)
 
Phillips SHE3590 tips isolate a lot better than the stock tips, to the point they "suck" on your ears a bit (they are completely enclosed).

Pros: Good overall sound quality, nice aesthetic design, one of the better "consumer" headphones you can buy at retail
Cons: Poor fit and durability, harsh sibilance
These were the first IEMs I bought that were over 50$ after reading good reviews on it. Unfortunately I don't think they live up to the hype. They are definitely better than some of the other consumer-oriented brands such as Beats, Bose, etc. but they are not worth 70 or 80$.
 
Note: I do not have my fully functioning S4 anymore because I recently lost it. (long story) The one I mention in this review comes in the blue CNET box (no cleaning tool, straight plug).
 
Sound quality
The sound quality is a V-shape signature with an emphasis on the highs. The bass is rather boomy but it does not overpower everything else and quite detailed still. The mids are a bit recessed when you first get these but they sound better after burn-in and using the bi-flanges clears them up while reducing sibilance. At first I found the highs to be rather metallic though this settled after burn-in, but the sibilance is still there. Overall, the highs are crisp but not very detailed. The soundstage is pretty good in size for an IEM. As these only go up to 19 kHz, they are a bit forgiving of lower bitrates. For my ears it is a bit harder to tell 128kbps from 320kbps compared to some other headphones. They also seem to amplify any sort of hiss.
 
 
Fit and comfort
This is probably one of the more disappointing aspects of the S4. Although I found the regular and large tips to be quite comfortable, the medium ones fall from my ears easily and moving them slightly off will kill the bass. Both cause the harsh sibilance I noted earlier. The "small" biflanges, on the other hand, take away this sibilance but take a while getting used to.They do take off a bit of detail from the highs unless you absolutely stuff them into your ears and keep it in that position (which I do not recommend because it has got stuck in my ear once). At the same time, they also bring out the mids and bass quite a bit more. Because the biflanges are small size, the noise isolation isn't as good as the large tips, although they still do isolate sound nicely. Like the medium eartips, they are hard to fit for optimum sound. Just moving them slightly off kills the bass.
 
Durability
Another problem is durability. The strain reliefs are especially weak and mine ripped within 3 weeks of use. That said, this isn't much of a problem as the cords still hold very well from the cans, and Klipsch has improved upon it in their latest version in addition to flatter cables. The cables in my version feel flimsy and do tangle when scrunched into your pocket, though they are springy so it's a bit easier to untie them. The straight plug on the other hand is poorly built. Putting these in my bag it somehow got bent to the extent that the center channel was removed like a karaoke. Fortunately, Klipsch sent me a free replacement (though I just recently lost this pair). It seems rather normal the plug is very slightly bent and not perfectly straight out of the box.
 
Value
If they were under 40$ (which you may find on the internet) this would be a decent pair of cans. Unfortunately, durability and fit are the two main problems the S4 faces. That said, it's still one of the better consumer-level headphones you can easily buy at retail stores like Best Buy or RadioShack, stores that don't always sell the best type of headphones. if you are still interested, get the S4 II because of its better build quality (and watch out for the prices as it is often more expensive if they sell the original S4).

I have had these headphones for some time, and I don't feel that they are hard to fit in my ears. I use the standard tips and they work just fine. I was concerned about this before buying them because of some reviews, but it was no problem. I would say that they work the best if you sit still, since if the cable bumps into your jacket, or something, a bump sound resonates into your ears and that's quite annoying. For running they are useless!
I have used them on long flights (ex. Amsterdam-Singapore) and after many hours, my ears got a bit sore, so I would rather recommend them for shorter commutes.
The noise isolation I find quite good, and the sound quality is in my opinion is also really good for these small headphones.

 the tips fit fine but if they move slightly off in my ears (if I yawn or something and my ears twitch) the bass goes away, and amount of sibilance with the standard-style tips is a problem. With biflanges the sibilance is almost gone and it brings out the warmth of the mids, but they don't isolate as well and your ears REALLY get sore from them.
