Hands on review Master & Dynamic MW07
True Wireless Earphones


Master & Dynamic is a company from New York who targets itself on the creative community. But a community who is willing to pay some extra for beauty next to sound quality. What were my expectations from this obvious premium product? I am used to some nice (but wired) Chifi in ear products from KZ and Tinaudio, and some over ear candy from Sennheiser. Recently I got a little disappointed after testing the brand new wireless Momentum. I was hoping for an improvement in wireless performance, and sound- and build quality next to Chifi. And I was willing to pay the price for beauty...

Well, the price is certainly premium. They did go as high as $300 but prices dropped to $199. Why would you wonder? Well, Master & Dynamic introduced a successor (MW07+) which has active noise cancellation (ANC) and a better battery life. There is also a cheaper knock-off (MW07 Go) which has cheaper build quality and no ANC. Amazon had a great deal for the ‘steel blue matte acetate’ for $99. I threw my money at them and a few days later the mailman came.

Unboxing and build quality *****

I’ll keep this brief as I don’t care too much for the packaging. It’s definitely better than cheaper products. A very neat white package contains a black cardboard box. Inside the box you will find:
  • A silver shining charger containing your new gems
  • A soft pouch
  • QuickStart guide
  • A good quality charger cable USB-C (with USB adapter)
  • Ear tips in 5 different sizes
  • 2 sizes of silicone fit-wings
The charger case steals the show here. It’s colored in high glossy silver with 3 led lights indicating status. The build quality is really premium as it’s made of stainless steel. It’s sturdy and classy and could go for some sort of ZIPPO lighter. Your fingers will leave prints on them, so use the pouch or a cloth to wipe it clean every few days. The cans themselves look stunning. The used materials provide the premium experience. I could not say it any better than M&D on their website:
“Beautifully eye-catching and durable finish, with a lightweight, slim design. Each pair of earphones may vary in its exact pattern and color due to the material and hand finish.”

Comfort ****
This is always very subjective. My ear canals are very small although my ears are not. So I benefit from a very slim earphone. This ones are not. They are rather bulky but they have some tricks up their sleeves... Master & Dynamic supplied additional ‘silicone fit wings’. This are some sort of additional supportive wings so the ear tip rests better inside your ear shelf. And I took some time to discover the best eartips for me. After some testing I found Spinfit CP100 in 2 different sizes to be adequate.

After this little ‘hack’ comfort is great! Although the earphones are rather big, they stick really well. They slide in my ears easily and I can wear them for longer times without pain or discomfort. For me a slimmer design would work even better. But of your ear canals are medium, or big, they will fit easily.

Sound quality *****
Now for the most important part: how do they sound? I am no outspoken audiophile so I will try to use terms which everyone should be able to understand :).In general these are v-shaped earphones, so the bass and treble are somewhat boosted. No EQ is necessary to make them sound good. The soundstage is wide but not to the extremes. For example: my cheaper MPOW M5 sounds little wider, almost outside my head. But the presentation of the stereo field is far better on the MW07. Note: please let them run for like 10-20 hours before testing them. You will find that after burning in, the sound quality will be much more pleasing than at first start.

I really love the bass! It goes so low you can feel it in your chest, although this is of course impossible. It’s got ‘meat’ and it never bores me. The level of detail is far better than many wired earphones. Because the bass does not seem to be boosted, the mids can really shine. So vocals sound direct and intimate also with lots of detail. I am a treble lover and these cans perform. Treble is not boosted but there is plenty of airiness and detail in the high frequencies. Again the level of detail confirms you are listening to a premium product. Call quality is nothing special, it’s perfectly possible to have conversation as long as you don’t walk in to strong wind or ride a bike.

Controls ****
Controls are different from other brands. On the left earbud, two physical knobs provide volume control. On the right earbud, one physical knob is multifunctional (pause, play, next etc.). I found out physical knobs are great compared to just a touch sensitive area.

Connection **
The earbuds can connect to 2 devices simultaneously. So you can listen to music on your tablet while it’s possible to answer your phone. Great! But my connection drops when I walk away from 1 device without disconnecting the other properly. Also I have experienced random connection drops while walking. After putting the cans into the charger, connection is reset. That could be better.

I am in love with these earphones. They outperform all my former Chifi earphones and I even wear my Sennheiser HD-600 less. Music sounds vivid, fun, and a critical listener will also be pleased with the sheer audio quality. On the office, they block enough noise and put music all around me. At home, I watch Netflix without any audio latency and call my friends. I love the way they look. True, if you travel a lot, maybe their successors (MW07+/MW07 Go) will be a better choice as battery life is considerably better. For me however, 3.5 hours on 1 charge is enough. Are they worth the price? Well for a premium product I would say that between $100 and $200 this is a fitting price. If you in it for the money, try to find an Amazon deal as I did. If money is less a subject, do not hesitate and buy the MW07 or the MW07+ in the color of your likings.

Master & Dynamic MW07 TWS And MW65 Headphones Review - Bluetooth Engaged

Master & Dynamic is a friendly company from USA, known for their excellent headphones, all of them having awesome features like ANC, APT-X Bluetooth and other bells and whistles that tell them apart from the competition. MW65 is priced at 500 USD, and will be compared to Ultrasone Signature Studio, and Sennheiser HD660S while MW07 is priced at 150 USD, down from 250 USD, and the closest direct competitor to it is HIFIMAN TWS 600, which is also priced at 200 USD at launch.


Master & Dynamic is one of those companies really nice to deal with, with a strong USA-based mentality and with a strong support for their customers and fans. They designed and created a large plateau of audio delicacies, including the MW60 headphones which I reviewed in the past. Most of their headphones are centered around a bassy, warm, fun and usually punchy signature, so we could say that Master & Dynamic has a house sound to them. If you ever purchase a product from them, you can expect prompt support, and if you explore the internet, you'll hear that everyone who had an issue with their products has had their issues solved. Furthermore, they run sales often, and you can find special offers for their excellent headsets, so if you're interested in any of their offerings, don't forget to check the latest price.

It should be noted that I have absolutely no affiliation with Master & Dynamic, I am not receiving any incentive for this review or to sweeten things out. I'd like to thank Master & Dynamic for providing the sample for this review. Every opinion expressed is mine and I stand by it, the purpose of this review is to help those interested in Master & Dynamic MW65 and MW07 find their next music companion.

About me


First things first, let's get the packaging out of the way!

The fun thing here is that we're dealing with a company that really knows how much the unboxing experience matters to the final customer. The thing is, most people will probably think at first, that once you open a package and take the product out, you won't care about the unboxing experience, but the truth is, unboxing experience matters. I decided to not include the word Unboxing anymore in my Youtube videos, because it seems to make some people think that there is less content in each video than it actually is, but having owned products outside of the audiophile hobby, I can tell you, I do care how those are presented. For example, all DSLR cameras are presented in a nice, fancy way. The same goes for high-quality drawing tables, even the cheapest Wacom tables are presented nicely, and some of those cost a mere 50 USD or 100 USD, yet they are presented, like they are the tables you will be using for a long time to make your art. The same goes for any product I have enjoyed, it is part of owning the product, to have a nice presentation to it, to have it presented personally, in the same way that you'd see it presented online.


The presentation for MW 07 is much simpler than that of MW65, which is a large headphone, but even for the headset which is now selling for 150 USD, Master & Dynamic did not skip the presentation part.

The IEMs come in a fancy carrying / charging case, and along with them, you have a rich selection of accessories, which include a good selection of tips, 5 pairs, in different sizes. There are also two pairs of spacers, which are designed to make the earbuds more comfortable for longer wearing sessions.

There's also a charging USB cable, which is made as a Type-C to Type-C cable, and it comes with a USB Type-A to Type-C adapter. Then, you also get a pouch, made from fabric, making MW07 one of the most rich and best presented TWS Earbuds at the moment of making this review. They make good competition for the RHA TrueConnect which I just reviewed on Youtube, and which are priced at pretty much the same price.

Build Quality/Aesthetics/Fit/Comfort


Starting with the magical one, those two little TWS IEMs come packed with features and reasons for you to purchase them. From the magical Be driver employed (just like the Be IEMs from Periodic Audio), to the fact that they have a dazzling battery life of 3.5 hours, with three additional charges, for a total of 14 hours of listening time, and given the fact that they have full charge and the case will have 40% ready to go in 15 minutes, and should last for an entire day of work with just a few minutes of charge, they almost sound like the perfect TWS IEM.

They also have IPX 4 Splash Proof rating, which means that you can easily wear them to the gym and do some light jogging / exercise while wearing MW07, without having to worry about breaking them. There's also a microphone inside, and you can take phone calls, and actually judging the phone call quality has been fun, because despite their small footprint, the person on the other side could hear me clearly, without my voice coming through as muffled, and without a lot of background noise.

The bluetooth is 4.2 APT-X, but as I've noted in my review of RHA TrueConnect, having Bluetooth 5.0 doesn't necessarily mean something will sound better, and having APT-X with your bluetooth will always mean that it sounds better than having just SBC codecs. Here, I'm really happy Master & Dynamic went the good (sonic) way, and included APT-X with MW07, you can hear that they sound quite amazing, and are actually quite easy to recommend for their sonic performance alone.

The connectivity distance is 20+ Meters from the source, and I measured about 18 actual meters from the smartphone, even with a wall in between, without losing connection. Furthermore, in all my tests, the two earbuds remained connected to each other once paired, and I haven't lost the connection between them even once, making them one of the most reliable TWS Earbuds I've tested to date in terms of connection stability.

The IEMs have a beautiful granite aesthetic, that will surely catch your eye, and they feel comfortable while being worn. There is no ANC employed, like with MW65, but MW07 still offers about 18 dB of passive noise isolation, wearing them in full traffic, while commuting, and wearing them while doing noisy activities won't be an issue. This brings us to the latest part of this review, the comfort. This is actually one of the two or three TWS Earbuds that actually had good comfort for me. There is some light driver flex and some void, but they sit really well in your ears, and you never lose them, even while doing heavy exercise. Furthermore, you can rely on MW07 to be there even if you're working from an office, as they leak very little, and you can blast them pretty loud before anyone notices anything is going on.

The case is also beautiful, but is also a fingerprint and a scratch magnet, and I recommend keeping it in the pouch while not using it, to give it the longest life you can.

Master & Dynamic MW07:

Sound Quality

Master & Dynamic MW07

This one is actually rather easy, MW07 has a pretty easy to describe signature, and there's not much else to it. The word is boom! There's bass, there's punchiness, there is a good kick, especially for those who love a warmer, more smooth up top signature, and there is a modest stage that paired with a fairly good separation, gives a natural presentation, especially for pop and commercial music.

Stating with the bass, it is a heavy, high-slam, high-impact, natural towards slow speed, and with a satisfying overall delivery if you're listening to hip-hop, EDM, Dubstep, Rock, Pop, and music which in general should have a high amount of bass. The speed is good enough for them to keep up with aggressive metal, without feeling bloated or slow, even grindcore sounds listenable and fun, but the bass is not made for technical music, like, for example for technical death metal.

The midrange is warm, and the emphasis in the bass is at around 100 Hz, which makes the midrange pretty thick and slightly veiled as well. This is what I would call a bass bleeding in the midrange, and it happens to a good extent, making the MW07 pretty warm and thick. I could even say their thickness is quite extreme, but this gives a fair advantage to male voices, or, to female voices, if you're very sensitive to a more aggressive treble.

The treble, indeed, is very rolled off, with little extension up top, a very buttery and smooth presentation, with zero fatigue and zero stress presentation. If you tend to be sensitive to treble, MW07 has been made for you, their signature works really well with all types of music, from EDM to Pop, to Dubstep, to Hip-Hop, but only works for rock and metal, if you're sensitive to cymbal crashes, or if you want that smooth, creamy presentation.

Portable Usage

The portable usage of both headphones is excellent. Most of the things I described before are my actual experiments and test results. More precisely, they did actually survive to the lengths Master & Dynamic promises, and I'm happy they weren't overconfident on the specs when describing their headphones.

MW65 is really easy to drive actually, and a source like iBasso DX120 should do a fairly good job at it. Compared to other bluetooth / wired headphones, like the M0 Headphones from MOOH, they are considerably harder to drive though. There are bluetooth headphones that are similar in general compared to MW65, like ARC-1 from AIWA. This being said, ARC-1 has way less battery life, and the considerably lower price comes, at a cost. The materials are much better on MW65, and so is the comfort and bluetooth stability.

There are many other headphones that are TWS and do a great job, like Lypertek Tevi, for example, which has been raved about, even by me, but I feel that MW07 will either be your thing, when it comes to their aesthetic, or not. They really are defined by the particular aspect that Master & Dynamic gave to them.

Master & Dynamic are known for premium materials, portability and for overall quality to their products. There are many alternatives, but you either fall for Master & Dynamic and their premium approach, or you're looking for something else, so don't I don't want this review to make it sound like those two are the only two models in the world that are good. There are lots of amazing Bluetooth products out there, MW07, MW65 are also two of those really good ones.


The main contenders here are the Signature Studio and Sennheiser HD660S, for MW65, and TWS600 from HIFIMAN, for MW07. Those are all at similar price ranges, but they are different products, the whole point of the comparisons segment of this video is to compare them sonically, and to explain what purpose each of those achieves, and help you decide what kind of product you need.

I will also skip over the pairings part of this review because both MW65 and MW07 are bluetooth products, and they sound similar with all sources. For the wired tests, I have been using either FiiO M11, iBasso DX229, or Opus #3, usually relying on quick switching and volume matches tests for determining the differences between MW65 and its competitors. For MW07, and TWS600, all tests were done on Bluetooth. I thought it would be really fair to include a comparison between MW65 and MW60, which I reviewed in the past.

Master & Dynamic MW65 vs Sennheiser HD660S - All is good and well, but when Master & Dynamic decided that MW65 will sell for 500 USD, they knew they had to beat HD660S, and they knew they couldn't just add bells and whistles like Bluetooth and Active Noise Cancelling, or ANC and stop there. So, they also gave their Mw65 a sound that would make them stand their ground in the market, and man, did they deliver on that. The package of the two is actually better for MW65, with a more rich package, more accessories, and with better earpads, longer lasting earpads, and with a better overall cable included in the package. I was a big fan of HD660S, but Master & Dynamic simply made a better package there for their MW65, Sennheiser were never adepts of a strong package, although their prices are on the high side, compared to HIFIMAN, which also has a more minimalistic approach, but which at least offers a good price, being a more budget, good sound, barebone headphone. In terms of comfort, HD660S is more comfortable, has a larger earcup, but the headphone sits tighter, and the earpad is tighter, making it sit slightly less comfy than MW65, where the earpads are softer and made of sheepskin. HD660S is really hard to drive well, so you will need to make sure you have the proper source, where MW65 can be driven from a midrange DAP like iBasso DX150, FiiO M11, or even an entry-level DAP like FiiO M6 or iBasso DX120. On the other hand, you need at least iBasso DX220 with AMP7 to drive HD660S, or something just as strong, like the newly released TR-AMP from Earmen, or iFi xDSD, or Chord Mojo. HD660S is an open-back headphone and leaks a lot of sound, it does not isolate you from the outside noise, and you cannot wear them in any public location, or near your loved ones, if you don't want them to hear your music as well, where MW65 does not leak, and if you have a crying baby around, you can cut yourself from it for a few minutes with the ANC function. When it comes to the sound, you will have the biggest surprise. I always took Master & Dynamic for a premium headphone manufacturer, but now they also have proper audiophile sonic quality, with proper textures, holographic soundstage, and more quality, more punch, and better dynamics than even HD660S, making them one of the easiest to recommend headphones at the moment of writing this review, if you want a high quality closed back headphone, one that sounds neutralish. HD660S is warmer, thicker, darker, has a more creamy presentation, where MW65 has more dynamics, more punch, and a more balanced signature, with better extension both in the treble and in the bass.

Master & Dynamic MW65 vs Ultrasone Signature Studio - Ultrasone signature studio was a really bright headphone, with a really quick and light bass. MW65 is a much more balanced version of that sound, and is also more comfortable, where Sig Studio was tighter on the head, with smaller earpads, which felt considerably harder to the touch, and became uncomfortable a bit faster than MW65, which I can wear for a few hours without wearing fatigue. In terms of package, both have an excellent package, and Ultrasone may have the upper hand here, with a better, yet less practical carrying case. In terms of sonics, Ultrasone is considerably brighter, and has less body, less punch, but better detail, and a larger soundstage. There are more textures, with better micro-detail with Sig Studio, but there is more dynamic, and a more balanced overall sound that is still very airy and extended with MW65, but which doesn't feel nowhere near as fatiguing as Sig Studio, which although is made for studio, can be very fatiguing after a longer listening period.

Master & Dynamic MW07 vs HIFIMAN TWS600 - Now, we should compare the MW07, to the TWS600 from HIFIMAN. You can tell from the start that Master & Dynamic invested more in the build materials of the charging / carrying case, and also in the earbuds themselves. There's better comfort for MW07 actually, and they sit better in your ear. HIFIMAN has a considerably different sonic presentation, with a much lighter and more neutral sound, where MW07 has a very heavy and thick sound. The two are polar opposites, and if you like bass, you should totally go for MW07, they are all about the bass. TWS600 has much better detail, clarity, impact and treble, but they have a very thin sound out of the box, and they need to be EQ'ed to have a more natural sound. I have taken some time to EQ them, and they take the EQ'ing well, but it is a necessary step if you want to enjoy them, where MW07 can be enjoyed right out of the box, if you're a basshead, or someone who enjoys a more commercial type of sound.

Master & Dynamic MW65 vs Master Dynamic MW60 - The new vs the old, what changes, and where is MAster & Dynamic headed? To answer all of those questions, I first need to tell you that my review of MW60 has been confirmed to stand true by the test of time, so they are exactly as described, and I encourage you to read it before reading this comparison, so that it makes way more sense. Where MW60 was imposing, deep and powerful, MW65 is neutral, clean, and crisp, with much more focus on the detail, clarity and overall soundstage. There's a much larger stage with MW65, and where MW60 was really warm and thick-ish, with a smoother treble, with MW65 you get a much edgier treble sparkle, with better overall extension and more air. MW60 was lush and full, MW65 is clean and sparkly, this would be the easiest way to compare the two, and to know which one should work best for you.

Value and Conclusion

We can draw an easy conclusion about both MW65 and MW07, which is that they are both premium products. They have those high-quality materials in their build, they have the fine craftsmanship, and the sonic performance to be sold at their current price points. This being said, there are other, more budget-oriented options out there, Master & Dynamic is designed for those who really want the quality and the experience offered by Master Dynamic.

The package is always interesting and beautiful to discover, there's a rich accessory setup with both MW07 and MW65. I'm a big fan of the fact that they have both wired and wireless modes for their MW65. Furthermore, I'm in love with the fact that you can replace the pads of MW65, making them last quite longer than those headphones where the earpads are there to stay.

Both MW07 and MW65 are comfy headphones, but for MW07, it should work with every ear size and shape, due to their overall design, the inner part being really nice for a wider number of ears. This being said, when it comes to MW65, things do not work quite the same, they are on the border for me, they simply aren't quite as comfy, since they are exactly at the edge of being on-ear and over-the-ear. This may be because I have larger ears, but still, it is something to keep in mind, you will be in contact with the earpads quite a bit.

The sonic performance of both headphones is excellent, but they went in different directions this time around. MW07 is more in tone with the typical Master & Dynamic signature, which is warmer, creamier, where MW65 ended up as a really revealing, clean, crisp and detailed headphone, that's pretty much neutral, to mildly V-Shaped. This is quite intriguing, and MW65 ends up being one of my favorite headphones, and I will also be adding it to Audiophile-Heaven's Hall Of Fame for their excellent sonic delivery, detail, but also for their build quality, and design.

At the end of this review, if you're looking for solid TWS earbuds, and especially since they are on sale, if you love the design of MW07, you should totally go for them. At the same time, investing the full price of MW65 is quite complicated at first, but the final sound is totally worth it, they are a headphone that should satisfy both your needs for something that is beautiful, has practical usages, but which has good details, a wide soundstage, holographic even, and with great instrument textures.

Full Playlist used for this review

While we listened to considerably more songs than those named in this playlist, those are excellent for identifying certain aspects of the sound, like PRaT, Texturization, Detail, Resolution, Dynamics, Impact, and overall tonality. We recommend trying most of the songs from this playlist, especially if you're searching for new most, most of them being rather catchy.

Review – Master & Dynamic MW07

Website - Master & Dynamic


Price: $299 / €299

Official MW07 product page

The MW07 arrives in the usual nice box as the other Master & Dynamic products. Similar to the MW60 but of course in a much more compact size. The accessories set and quality is very good and are well arranged. There is a USB cable of Type-C to Type-C with extra adapter for standard USB (Type-A), five sets of silicone ear tips and two pairs of ‘Fit Wings’, which are basically silicone adapters to give a tighter, more secure fit to the wireless earphones. Also there is a small cloth pouch with a clasping closure, and obviously the charging metal case where the MW07 true-wireless arrive inside. The metal case is made of polished stainless steel of good quality with a mirror like finish; it is on the heavy side and can be prone to scratches easily. The charging connection is fortunately the modern Type-C USB.


For the $300 price, the MW07 design and quality are very good for a true wireless earphones’ set. A premium looking and elegant design, made of quality acetate material, handcrafted with a very unique and smooth finish. The outer plates are available in a nice variety of color themes, some more discreet and others more fancy. The inner part is rather compact, and despite the 10mm driver inside and all the wireless tech included, they have a very ergonomic, more rounded shape similar to any standard wired in-ear set. The ear tips are a bit thick but do provide a good seal.

Weighting around ~9g might sound heavy for TW sets, but nothing out of standard for in-ear models. Moreover, the MW07 actually sit well on the outer ear area and with the Fit Wings the fit is very secure if a bit tight. A smaller size of the ‘wings’ could be included as the already attached medium size can a large for smaller ears, and while can be used with no wings the fit won’t be as secure, especially if going to be worn on the go. Isolation is decent, the fit is neither too shallow nor too deep, so very similar to any common IEM pair.

There are three physical buttons on the MW07. One multifunctional single button on the right earpiece that works for play and pause, pairing, track skipping, and, if available, for voice assistance. The left side has the other two buttons which are only for volume control. The volume levels are very good, there are no strong jumps from one step to another so the sound can be well adjusted without using the source volume control.

Battery and Wireless performance

From a single charge the battery holds around 3 hours of continuous use at moderate listening volume, and the charging carry case can add three extra charges. At 2019 this numbers are the very standard for a true-wireless option, and even more for a $300 one. Charging time, however, is pretty good, both for the earphones and case.

The MW07 cannot be turned off. Instead, the earphones will enter into standby mode for lower battery consumption. It is not something optimal, considering the average battery time, especially if taking them out for a whole day, and carrying the heavy charging case every time can be a bit annoying. As an extra feature, when either side is taken off, the music will pause automatically and resume when both sides are at a corresponding short distance from each other. Moreover, only the right earpiece can be used alone.

For the wireless connectivity, the Bluetooth is of 4.2 version and limited to AptX codec. It may sound somehow outdated versus the many true wireless sets that use last BT 5.0, but the wireless quality is very good. Pairing is quick and the connection is solid with no drops or interference so far. Also, the wireless range is wide enough; not sure about the 20m distance, but still better than average. Works very well with the FiiO M6 player which has one of the best Bluetooth connection on portable players, even over more expensive full Android based ones.


The MW07 utilize a Beryllium single dynamic driver of 10mm diameter per side. This is not the first earphone that I tried with a Beryllium driver inside, and also the second M&D product I get to review. The beryllium drivers seem to share similar sonic characteristics with full bass response and overall warm signature with a rich midrange. Even more, the MW07 seem to share a typical tuning of the M&D gears, which at least, was found on the MW06 headphones. Of course, we’re talking about different dynamic drivers in both type and size, but nonetheless the MW07 offer the warm, powerful and rich sound presentation. It is a type of sound that focus more on being musical and enjoyable rather than highlighting the little details, with a smooth and a bit laid-back nature, but then, for a TW set it is not particularly missing on clarity and resolution.

With a single 10mm dynamic driver the lows are rather powerful and dominant that gives a bit of darker tonality. Not a true bass-head IEM per-se, but plenty in quantity with more enhancement at the mid-bass region over the sub-bass, which may sound limited, though probably due the true-wireless limitations than the beryllium driver type. While the whole bass is forward and thick, it is not too overpowered as to sound muddy or shadow the rest of the sound. It is indeed aggressive, fun and enjoyable with decent layering and separation, at least for what the wireless quality can go; speed is also a bit better than expected. A clear trade for more quantity over total quality and control that suits well the active use than the more technical listening.

Expectedly, the bass blends into the midrange; mainly on the lower mids and still noticeable at the upper mids. The whole midrange sits a step further at the whole presentation, not too seriously distant as to sound thin or missing. Thanks to the strong low end, the midrange tonality is warm and full, and while overall smooth, there is a bit grain at the upper region. Lower midrange can sound drier next to the upper midrange, either on instruments or vocals; even so, the voices are richer and well-presented despite the less midrange focus.

In terms of balance, the highs are just a bit more forward than the midrange, but clearly not as present as the lows can be. As such, the treble can give a tad of lively presentation, but not in a v-shaped signature. The gain is more focused at the lower treble region giving more energy and sparkle to instruments and enhancement to female voices. For true wireless set, the detail retrieval is actually very decent, and while limited in extension or not as natural as typical wired will sound, the drop in quality is less noticed thanks to the more laid-back, smoother nature of the MW07. Not meant for picking micro details, but yes to sound fun, musical and enjoyable.

MW07 VS Zolo Liberty+ ($100~150)

Next to the MW07, the Zolo Liberty+ set is a more recent true wireless model implementing Bluetooth 5.0 and extra codecs. It also has a higher IPX5 rate over the IPX4 on the MW07. The build quality is tougher on the MW07, while the Zolo is slightly lighter. Fit is tighter on the MW07 with a deeper nozzle length and angle; the Liberty fit is more shallow and the Fit Grip do not fit as natural as the Fit Wings on the MW07. Isolation is almost the same on both sets.

In terms of sound, these are 10mm beryllium vs. 6mm graphene single dynamic drivers, yet both offering a warmer overall tonality. The Liberty+ offer a more lively v-shaped signature with the extra energy on the treble area sounding brighter over the smoother MW07. There is more bass quantity on the MW07, with a stronger mid-bass lift and impact, whereas the Liberty+ low-end is more even in sub and mid-bass. If the Liberty+ is more aggressive on the highs then the MW07 is on the bass. Midrange is very similar on both sets, being more distant at the overall presentation but still not lacking fullness of notes. The stronger mid-bass emphasis on the MW07 can overshadow more the lower mids; even so, it is still richer and natural in texture, whereas mids on the Liberty+ are a tad drier. The detail level is very similar. The sound stage is a bit wider on the MW07 with more depth, too.

They have released new versions which are Go and Plus. Should address many of the disadvantages that exist previously.
