Audiosense DT300

who is audiosense?

there are legendary models such as the t800, a chinese company that usually puts products on the market above certain standards but has been silent for a while, and usually the brand uses its own well-known tune. They have also given more than 50% discount for the dt 300, so I thank them. I have no affiliation or affiliation with the brand other than the discount for the dt 300, as always I will try to write an honest review.




box contents;

If I compare it with the whizzer boxes that are reference for me, I can say that I encounter an average box for the price band. If the storage box, which I love so much, did not come out of the box, I would probably criticize the brand seriously. The box contents are as follows;

- a pair of iems
- a cable of average quality for the price range
- 12 pairs of eartips, 3 pairs of foam and 9 pairs of silicone (in 4 separate plastic bags, I wish they had been put in something different)
- a cleaning brush with two functions
- A tool for removing and attaching mmcx cables
- user manual of the brand
- a very high quality and waterproof storage box (probably one of my favorite earphone storage boxes)







iems and cable quality;

iems made of resin and decorated with various visual decorations welcomes us. I can say that it is one of my few favorite designs. they are not very small but they are quite light, they are transparent so you can see the drivers inside. they look pretty cool, the cable is mediocre for the price band. I think a better cable could be accommodated, but I'm not complaining because it's a cable that doesn't tangle and has no memory, so there's no problem. although I don't like average quality cables, I don't think I will order a new cable for my dt 300 because the dt 300's own cable is quite light and comfortable.












sound quality;

Those who use audiosense know, there is a sound signature that the brand uses in general. The dt 300 is also a headphone, well known for its audiosense overall sound signature, v-shaped and bright. You feel an overall intense listening experience. I can not say that the sound is warm, the general character of the sound may change depending on the headphone amp you use. I generally like the sound character of this iems more with warm sources.

bass; It's as good as an average dynamic driver, I'd argue it has as good a bass as most dynamic drivers under $100. If I was a novice listener I would probably have thought this was a hybrid iem. You can tell that the iem do not contain a dynamic driver, only because the bass is not too sharp and energetic. For a iems with a balanced driver, it has even better results than I expected, and in terms of bass speed, I can say that it is average.

medium frequencies; It is quite detailed but indented, I would recommend those who prefer vocals to evaluate different options. Except for vocals, most instruments in the midrange sound lagging and some instruments are a bit more unnatural, at least for the price band. If you are listening to medium frequency music, you can find an average iems, perhaps this is the weakest part of this iems.

highs; yes, that's where this iems bright. The trebles are bright, detailed and energetic. They play in such detail that they amaze me. If you have treble sensitivity, I recommend trying foam tips. by the way, one of the reasons why this iems offers an intense listening experience is the bright and detailed highs, and if you have treble sensitivity, this fatigue can increase a bit more.


resolution;

when I say dt 300, the first thing that comes to my mind is high resolution. The difference of the 3 balanced drivers in the earphones is evident here, very high quality drivers are used. The mid frequencies are already detailed, but the details I heard in the upper frequencies surprised me a lot. everything is very clear and you can hear all instruments clearly, I tried a lot of things in the 0-150 band and I have never come across a headphone with such good detail separation. (I haven't tried hexa)


sound stage;

I can say that the first thing that caught my attention was the scene that was quite successful in depth. I've tried different headphones with in-depth scenes before, but they weren't for everyone, they either sounded cavernous or muffled and lacked detail. There's a very well-adjusted depth here, and it's above average in width. instruments do not interfere with each other. One of the things I can criticize about the sound stage is the positioning of the artist and some string instruments a click away.




comfort;

Since it is a resin earphone, it is quite light, which means this earphone is very comfortable in terms of material. Since the cable is also quite light, you can keep it in your ears for a long time, it is not as comfortable as a waner sg, but it can be said that it is good in general. As for listening comfort, things change a little there, bright trebles and intense details are a bit tiring, I don't think I can listen for a long time with standard silicone tips. In terms of insulation, it is more successful than most of the models I have. Since there is no ventilation, the insulation can be increased even more with foam fly. by the way, you may experience a feeling of clogging in the small ear canals because there is no ventilation, although it is a general balanced driver issue, I adapted after a while. Although it is comfortable as a material, it is not that comfortable as a listening experience.


a strange experience I had;

I especially recommend placing the audiosense iems in your ears well, because audiosense iems that do not reach a certain depth can make you feel an awkward soundstage. Even positioning the iems a few mm behind can cause serious sound character changes, I'm not saying push it too deep, but you still need to place the dt300s in your ears at a certain depth. I experienced this for the first time with audiosense.


last word;

If you are looking for a headphone that plays in detail, the dt 300 is a really must-try headphone. It's a nice looking, lightweight and very good sounding headphone. Although it is generally in the $190 band, it is not difficult to find figures like $110 during discount periods, probably even the best $110 you can spend for a iems. I have more than 20 iems and the dt 300 is the one I listen to the most at the moment, although I like mid-frequency headphones, the dt 300 is always pleasant to listen to. When I paired it with a source like es 9038q2m, they started playing even more detailed, they're already on my top 5 list for me.

Forgive me, I can't write a lot about this model, not because it is bad, it's just very balanced, and reading some positive epithets is not interesting to anyone, because people from the beginning of time love bread and circuses (blood). There will be no blood here lol

Build quality and material quality are of the highest standard, like all Audiosense brand products

Sound. This is a neutral and warm 3BA supply, due to the warmth, the DT300 can be listened to for a long time without any signs of fatigue. Good separation of plans, average quality of detail and scene, good and elastic bass. BA are tuned very coherently, no joints and domination of a certain frequency are heard

The design is one of the most beautiful (there are many similar ones on the market) that I have seen. It is impossible to start listening to the DT300, I want to constantly hold them in my hands and admire them, although maybe this is just my problem lol

I really regret that before shooting the DT300 the photography light (photo equipment) broke and I did not get the perfect photo quality. When the new lighting equipment arrives, I plan to take new photos of this audio art masterpiece

The IEMs is definitely not for bassheads and fans of ultra-saturated high frequency

I recommend Audiosense DT300

Hello mates, welcome to my another review here in Head-fi and right now, I'm introducing to you a new product from Audiosense.



We are all aware that Audiosense has cemented its status among audiophiles and audio enthusiasts alike as reputable audio company for they deliver some of the matured, well-tuned IEMs and a product of high quality value with decent pricing. Their most recognised and well-received product was the Audiosense T800 and we know the accolades and some praises that it received which were mostly positive feedbacks from the audio community. This year we will expect another good product from them that they will surely suprised us.



To be honest this is my first own Audiosense set in my collection as I was recommended by a resident Head-fier to them and gladly that Audiosense give me an opportunity to do a review on their product. I can assure that I could give an honest feedback and opinion on what I perceive on it (Well, headgear reviewing is indeed a subjective one as it should to be taken as a grain of salt.)



And now I'm introducing one of their latest product from their current DT series line-up, The Audiosense DT300. The Audiosense DT300 is an all Balanced Armature drivers set-up IEM encapsulated in a 3D printed resin in an UIEM mold. This set is cost around US$179/£129 and currently available in all e-commerce platform.




Before we deep dive on the sound quality and its characteristics on tonality and technicalities. We will look on how its retail packaging box is presented and its content inside. The box itself has a black sleeve with an Audiosense logo at the top left with a simple illustration of the DT300 at front and specifications at the back. Then the inner cardboard black box to the inside consist of the pair of IEMs, a white 16-core SPC cable (Mine has some minor issue on the stock cable included out of the box but Audiosense act instantly and manage to send a new replacement cable within a week with better one, a 16-core SPC OCC litz cable.), a three (3) different types of eartips in three (3) pairs and different sizes (a typical medium bores stock ones, a Sony-like stock eartips and memory foam), a pretty damn good tough Pelican/Otterbox-like IEM case, a cleaning tool, a velcro cable winder and some paperworks like instruction manuals and warranty cards.



The shell of Audiosense DT300 is made of high-quality 3D injected moulded resin that has tinge of between an aquamarine and turquoise, And a quite a little bit hefty on it which is comparable to some IEMs with metal alloy shells.The handcrafted painted faceplate is such a gorgeous as it was inspired by colour pattern of an abalone shell. It's 3(three) balanced armature drivers are all premium ones as they are sources from a reputable audio driver manufacturer, Knowles. And these are the following series of drivers that was implemented in DT300: CI-22955, ED-29689 and WBFK-30095 which are have its own tubing channels to lay out better reverberation and less distortion of each respective frequency range. The shell design fits snugly into my lug holes perfectly as I can wear them for a long listening session without in any stress and soreness in concha and tragus part in my ears. Isolation does really work well as it really blocks some external noises from the surroundings in a manner that you will hear clearly the sound quality output from the IEM. It has an MMCX connector for better flexibility and stability on its socketed connection but I really prefer 2-pin connector due to its proven design on longevity, more stable and easy to connect and better resistant on wear and tear on doing cable swapping (I myself isn't a fan of cable swapping.) I don't see any ventholes in this particular set that might give some uncomfortable forming of air pressure produce by the BA drivers to some individuals.



Audiosense DT300 is an easy to drive IEM as it has a low impedance value at 11 ohms and a good sensitivity rating of 106 dB which are loud enough at 40- 50% volume and can be power by decent sources from decent sources, But it really scales well on better high-quality DAC/amps from audio-centric smartphones like the LGs and Meizus and DAPs that really shows its fullest potential and capabilities as a competent sounding IEM.



When its comes to sound signature, This set reminds of that neutrality tuning of ATH-M40x and Shure SRH 440 but with perhaps better technicalities. This IEM is tuned to be an almost uncoloured neutral one, indeed leaning to be flat sounding due to its negligible and paltry elevations and scoops to coupled its values along its frequency range. There is slight emphasis in the midbass then more linear and neutral mids and quite a noticable scooped on the lower treble then a smoother and a meager peak on the presence part of treble (around 7.5k to 8K range) based on my hearing perception.
It is also noted that some audio reviewers put up an impedance adapter on this set to improved its tuning to add colouration across its audio frequency range. But it's their own methodology and I have my own preferences and testing values so the matter of doing an assessment on this set is subjective.




Here are the description of sound characteristics and values on each respective audio frequency ranges.


LOWS/BASS:

The bass quality is actually impressive, while this set has only a woofer-type balanced armature specifically for low ends spectrum, It really does mimic that dynamic driver's thumping nature. It has the punchiness, precision and ample impact if some certain bassy track demands for its presence in the mix. The transients respond on this set is quite fast as it handles well some of the tracks with rapid bass kicks and how does it handle its swift decaying rate . The subbass has decent subtlety across bass frequency range as I hear some presence of rumbling and grumbling sound on its lowest part of spectrum. Midbass has a fair amount of textured body as it gives some bass kicks an impactful and penetrating sound and bass guitar still shows it grittiness and respectable growl. I can verify that there is no showing signs of bass bleeds across it frequency range.This might not be the basshead's preferences on a quantity bass but its qualitative aspect shouldn't be ignored.

MIDS:

The mids here are remarkable in my opinion as it is a transparent, smooth and linear as it sounds well-balanced with consistent coherency. The presentation of vocals on both genders, No matter what type of vocal range and singing style they have, They do really sound crisp and natural. Male vocals has the texture that belt out from the midbass as they across along through mids sounds has resonant and deep feature sounds really organic and accurate. Female vocals have that crisp and decent resolution but in some vocal centric tracks, There are instances that the female vocal's reach is somewhat smoothen as its does limited its extent definition, not that it sounds veiled but they have limited and polished out some edginess on it but it is still carry out those quality aspects of a well tuned vocal-centric tuning. The class of percussives, rhythm and wind instruments are sounds well-detailed and intuitive for they show an exact timbre of each instruments as acoustic guitar sounds crunchy and shimmer, the articulate plucking and twanging of both rhythm and lead guitars, the rich tone and mellowness of a piano and that distinct penetrating and precise strikes on snare drums. As a audio enthusiast that also likes a midcentric tuning, constantly checking on a quality of mids in the audio frequency in every time I do some reviews, I gave it a moderately high mark rating.


HIGHS/TREBLE:

The quality of the treble is smooth, neutral and suprisingly has that satifisfactory extension reach. Definitely this is not bright tuned set as its sizzle and sparkle nature was a little bit tone down but it still does have an acceptable detail retrieval. I'm aware some scoop down on either uppermids or part of presence treble as its has only have an ample enough of energy and scintillating definition.The possible decision that I surmised on why Audiosense decided in this kind of tuning on the treble is to avoid grainyness, harshness and sibilance that might ruin the neutral and pleasant tonality within its frequency spectrum. The cymbals strikes still has that shimmer as it really sounds intrinsically with sense of natural decayness. As I said before that it has satisfactory treble extension. It does really have sense of adequate airiness that trebleheads will pay attention and probably might forgive the DT300's treble quality as they might perceive it as darkly tuned one but on my humble opinion, I classify this kind of treble as safe and moderately leaning towards being a dark sounding.


SOUNDSTAGE AND IMAGING:

The soundstage of this set is quite wide and spacious based on how I perceived and imagine its dimensional size but it has only have an average depth but it was compensated with good reach on height. Separation and layering are one of impressive and exceptional aspect of this particular set as instruments do really have that sense of distance and spacing on one another as their placement on each row are distinctive and was located accurately. Defining spatial cues capability on this set is indeed commendable as it really show its good imaging prowess of the DT300.

To sum up my assessment of this unit, I would say that this is indeed the most neutral and almost flawless uncoloured IEM that I've encountered on this price range. This kind of tuning is also good for monitoring and mixing for audio professionals and for also critical listening audiophiles who really want an accurate reproduction and a flatter frequency response. I really love a neutrally tuning head/eargears as they are my preference for my listening leisure on my multi collection of tracks from different genre.

While this is not the most energetic, resolving detailed and best resolution retrieval IEM around its price range, Audiosense DT300 do really offer an alternative option; they propose to us a different path which is a neutral, good tonal balanced and coherent sounding one.

Overall Rating: S- (S+ to D-)

Category: B (100-300 USD), MSRP 180 USD, Acquired at: 80 USD (Reviewer’s Discount)



Overview:

The Audiosense DT300 is the brand’s latest offering in the 100-200 USD price range. It comes with a very-high quality waterproof case, 4 pairs of eartips and an 8 core SPC braided cable. It features an all-BA setup with 3 knowles drivers in a solid resin housing.



Inclusions: S+

The unboxing experience is incredibly premium. It comes in a minimalist slide-out box the opens to reveal a very high-quality waterproof “pressure venting” case. Inside are the IEMs nestled in some cut foam and the accessories. 4 sets of eartips (with SML sizes) are included, two sets are non-descript, 1 is a set of the common “Sony Hybrid” tips, and 1 single sized set of foam tips which are what I used. The included cable is an 8 core braided cable that I consider to be very mediocre. It’s quite thin, it has a little bit of memory and the earhooks are a little stiff but is otherwise very serviceable. Only the splitter and chin-slider are metal, with both the MMCX and 3.5mm terminations being made from plastic.



Build: A+

This IEM is built out of a solid chunk of 3d printed resin which surprisingly is very smooth, with the drivers being fed to the nozzle via tubes. It uses an MMCX connector which is somewhat wobbly in your hands (would’ve preferred to see a recessed 2-pin or NX7 connector personally, it also adds to the tangly-dangly of the cable). The shell is a safe shape with very rounded protrusions, slightly wide but quite flat which is great for those who listen in bed. The shell has no venting holes whatsoever which I found to be an issue when using silicone tips, as pushing them in at all would cause a pressure vacuum to form causing discomfort and affecting the sound. I found that using the included foam tips managed to circumvent this issue, as it doesn’t seal off air in the same way the silicone tips did, although the comfort still won’t be as good. Isolation on these is above average, the solid 3D printed shells are really good at absorbing noise, particularly with the foam tips.



Sound Review Conditions:

• Listening was done mostly with an impedance adapter (JCALLY 75ohms) but also without. Differences will be noted.
• The included foam tips were used because with the unvented design, silicon tips caused an uncomfortable pressure build-up.
• Stock MMCX Cable was used
• Sources used: Deezer and Tidal HiFI, Foobar 2000 HR-FLACs and PCM, Spotify, and YT Prem
• DAC/AMPs: Zishan Z1, KGUSS BH-3, and AVANI, JM20, CX-PRO Dongles

Sound:



Bass: A+

This is not typical BA bass. The bass is present, textured and dynamic with good extension and clarity. The full-range of low-end is all present and distinct despite bass being recessed in the mix. There is no bloat with the sub-bass into the mid-bass. Speed is good with even the quickest of drum fills reproduced properly, and in a properly recorded track different drums can be positionally identified, although with some concentration required. Detail reproduction and decay are also both very well done with loads of texture and microdetail present. Overall, bass presentation is good, if a bit on the lean side.



Mids: S-

My favorite part of this IEM. Good timbre for a BA IEM. Not a whisper of sibilance, even with tracks like Torn – Natalie Imbruglia, it’s still somewhat harsh but listenable. Crisp with plentiful texture and detail but also lush and smooth especially with the impedance adapter. Vocals are quite forward in the mix but coherency is handled very well with the full range reproduced properly. Guitars have their appropriate grunge and crunch with the harshness reproduced in a way that makes it feel like a musical element rather than a flaw. Forward elements are made more musical but without sacrificing their inherent bite in the initial tones of the note. Strings sound very organic and the resolution that this has allows them to really show off their individual characteristics.



Treble: S-

Neutral and inoffensive, with again, good details. Texture is good, it reproduces both the crisp and airy hits of cymbals well, and the differentiation between the hi-hats, crash and ride are easy to distinguish when you listen for them on properly recorded track. It’s not as pronounced as the mids or even the bass, however it is still present in the mix and does a good job of not getting drowned out, even in buisier tracks. On tracks where the cymbals are wider out, it does a good job of layering with distinct space but without separating from the rest of the mix and with the relatively wide stage that this has the distance is usually track dependent rather than being bottlenecked by the IEM. Overall, the treble is good, no harsh peaks or overt forwardness but without fading into obscurity.



Technicalities: S

This IEM is, for the price, very detailed. From the tiny rattles of a loose cymbal to the rattle of drum heads this IEM will reproduce quite a lot of the tiny details hidden within a track if you listen for them, it’s something it does better than what I’ve heard in this price range before. The stage is quite wide for what it is and is definitely wider than my BQEYZ Summer (130$). The instrument placement is distinct and natural, but imaging could be a bit better, as it can sometimes require some effort to pick out instruments instead of being effortless. Transient harshness is pretty much non-existent.



Impedance Adaptor:

Most of this review is done with an impedance adapter (IA) but here are some of the differences I noticed. The IA presentation is more natural, with the vocal presentation in particular sounding more organic and open. Removing the IA makes the sound a little more forward and harsher. The bass presentation without an IA is somewhat flat and plain, with an almost “clincal” presentation where it’s present and reproduced but sterile of any character. The IA bass is better extended and more dynamic. Treble seems mostly the same with IA and without.



Conclusion:

This IEM is a great all-rounder that offers good value for money and a superb overall experience at it’s price range. The comfort can be an issue, but foam tips or any other vented tips should fix that issue. It performs equally well for a variety of genres and is well suited to anything you throw at it whilst being tonally inoffensive and presenting naturally.

Unboxing and Accessories:
The DT300 comes in a black rectangular box that's very smooth to the touch. Removing the sleeve and the magnetic flap of the box reveals a large, clear waterproof case that contains the earphones, which is snuggled up in foams, cable, and all other accessories. Accessories include a cleaning tool, 4 sets of different eartips, velcro strap for the cable, and an instruction manual.

The eartips, from left to right in the picture, are the GT40S, S400, generic silicone tips, and the AT400/AT100 foam tips.

Build:
The shell is made of 3D printed transparent resin. The surface is glossy and very smooth. The faceplates sport the Audiosense logo decorated with abalone and gold flakes. The pattern of the flakes is unique to each shell, so no 2 shells and pairs share the same pattern. Looking at the other side you will see the 3 balanced armature driver units that they used with a tube attached to their individual nozzles going to the main nozzle of the shell.

The cable is the standard Audiosense 8 core silver plated copper which is very soft, lightweight, and tightly braided. The male MMCX connectors are made of plastic with color coded side indicators. The splitter and chin slider are made of metal, while the 3.5mm L-type gold plated plug is made of hard rubber.

Now let's get to the sound.

Lows:
The lows are big sounding, full of impact, and has great texture. Subbass surprisingly reaches very deep, along with a just enough length of decay. It also has a great level of rumble. Midbass is neutrally placed and noticeably solid, with a thickness that is slightly elevated. There is no audible bleed of the lows to the mids.

Overall, the DT300 surprised me with its lows, considering it has an all-BA setup. It doesn't suffer from the infamous "BA bass" stereotype. The lows never felt insufficient, and provides that substantial thump when the song calls for it.

Mids:
The mids sit at the center of the mix and fractionally lean to the front. Vocals are slightly forward and reproduced with great clarity. Male and female vocals sound very natural and lively. They share the same note weight that is slightly thick. The mids have no weird peaks so it never sounded harsh or aggressive.

Overall, the mids are nicely articulated. The added thickness and slight forwardness make the mids sweeter and contributes to a more fun listening experience.

Highs:
The highs are slightly smoothened and have an adequate amount of sparkle. It is well controlled but doesn't get drowned out by the other frequencies. Treble reach and its decay is average. Just like the mids, there are no peaks here that can cause uncomfortability.

Overall, the highs have a neutral presentation. It does not get aggressive, it does not get lost in the mix especially on complex tracks, but it simply stays audible in the background throughout each track.

Soundstage and Imaging:
The stage has an above average expansion, with the height having slightly more space than the width. The stage adds a very natural feel of airiness and openness to the music. Imaging is above average, instruments and their positions can be identified and pinpointed fairly easily. Layering is great as well as the separation. Congestion is very minimal especially on well recorded tracks.

Comparisons:
Audiosense DT300 (3 BA, 180 USD) vs. BGVP DM6 (5 BA, 189 USD)

The DT300 is evidently louder. DT300 has longer decay and more rumble in the subbass. The midbass sounds thicker and more forward in the DM6. The mids sounds way more natural, open, and transparent in the DT300, although they have the same thickness. In the treble region, the DM6 has more reach and decay. The DT300 doesn't fall behind much but it does not have the sibilance tendencies of the DM6.

Conclusion:
The Audiosense DT300 offers great value for money. The shells are beautifully designed, well built, it's smaller than average so comfort will not be a problem for most people, not to mention Audiosense included a lot of different eartips to help with the fit and for tweaking the sound. While the mids and highs sound pleasant and I consider them to be mature, the lows really surprised me here. It doesn't reach basshead levels, but definitely it is there when needed.

Disclaimer: I bought this with 50% off from Audiosense, thank you very much.

S/M/L fake Sony silicone tips


Cable: SPC 8-core cable. It is the standard cable for Audiosense that comes with pretty much all their iems. Measures at 0,36 ohms, pretty decent. But build quality on it is not good with plastic connectors (metal divider) and the plastic for the ear hooks are very noticeable. Has a working chin-slider.







Build: Resin build, ventless shell. Has a metal mesh in the nozzle (looks like there are 3 bores in it) and a little lip for the tips. Shell is on the average side and doesn’t weight a lot.

Fit: Good for me, it takes up my entire ear and stays still.

Comfort: Not comfortable due to the pressure build up.

Isolation: Very good isolation thanks to the shell shape but also because of the ventless shell.

Setup: Schiit Asgard 3 (low-gain, volume around 9 o´clock), Elecom EHP-CAP20 tips L, stock cable 3.5mm

EQ WILL BE USED IN THIS ENTIRE REVIEW, BECAUSE THE STOCK TUNING IS GARBAGE!

Lows: Different from the usual BA bass, as it is on the slower/looser side with decent texture. Timbre is good for a BA; sub-bass is a bit more elevated than mid-bass.

Mid-bass: Metallica – fight fire with fire (01:11-01:52), a bit bloated, needs to be tighter and cleaner. Quantity is also pretty low; texture is decent but individual bass strikes aren’t very distinct. The (02:55-03:01) section with the chopper is hearable but very muddy.

Hiroyuki Sawano – Pretenders (01:18-01:47), quantity is pretty good and it is fun and texture is good as well. It could be tighter though, speed is ok.

Sub-bass: Djuro – Drop that bass (01:15-01:30), extension is poor and doesn’t rumble very much as expected from a BA. Punch quantity is also lacking, texture is decent but could be tighter and faster.

Will Sparks – Sick like that (03:08-03:22), texture is decent but quantity could be higher and tighter.

Mids: Decent vocals, but bottlenecked by some BA timbre and is a bit unclean.

Female-vocals: Hiroyuki Sawano – OldToday (01:25-01:52), vocal tonality and timbre are pretty good but lacking a bit clarity. Instrument tonality and timbre are very good as well, but again, lacking some clarity.

Yuki Hayashi – MightU (01:58-02:55), vocal tonality needs to be brighter but timbre is very good. Instrument tonality also lacks some brightness but timbre is good.

Evanescence – Bring me to life (01:18-01:35), not shouty or peaky at all.

Hiroyuki Sawano – Crescent (02:07-02:26), slightly peaky and chaotic.

Male-vocals: Hiroyuki Sawano – Pretenders (00:57-01:17), vocal tonality and timbre are pretty good but lacking some clarity. Instrument tonality and timbre are good but not that clean.

Hiroyuki Sawano – Scapegoat (00:57-01:17), vocal tonality and timbre are good but lacking clarity. Instrument tonality is good but timbre could be better.

Treble: Linkin Park – Shadow of the Day (03:24-03:42), electric guitars aren’t sharp but is lacking a lot of clarity, timbre is decent.

Deuce – America (03:03-03:16), not shouty but very chaotic.

Hiroyuki Sawano – Lose (string version) (01:22-01:59), Cello tonality is very good, timbre and texture are decent but clarity could be better. Violin tonality needs to be brighter; texture, treble-extension, timbre and clarity could be better.

Hiroyuki Sawano &Z (02:18-02:57), tonality is decent but could be cleaner, timbre is ok.

Soundstage: Average, nothing special.

Tonality: Timbre is good for a BA iem, Warm-neutral tonality (keep in mind, this is with EQ).

Details: Detail is below average.

Instrument Separation: Separation/imaging are below average.

Songs that highlight the IEM:

Good genres: Acoustic/vocal music, OST

Bad genres: Trance, EDM, Hip-hop



Comparisons:

IEM: Audiosense DT100, Final Audio Type E tips LL, cable A6 4.4mm

Bass: Djuro – Drop that bass (01:15-01:30), extends lower on the DT100, similar rumble. Punch quantity is similar but more textured on the DT100, similar speed/tightness. Cleaner on the DT100 as well as more accurate tonality and timbre.

Hiroyuki Sawano – Pretenders (01:18-01:47), similar quantity and texture, but cleaner on the DT100 due to the tighter bass, similar speed though. More tonally accurate and better timbre on the DT100.

Metallica – fight fire with fire (01:11-01:52), cleaner on the DT100 due to the faster bass, although separation is worse on it and treble is a bit peaky.

Mids: Hiroyuki Sawano – OldToday (01:25-01:52), instrument/vocal tonality and timbre are a lot better on the DT100. Also sounds cleaner.

Evanescence – Bring me to life (01:18-01:35), a bit peakier and more fatiguing on the DT100.

Hiroyuki Sawano – Scapegoat (00:57-01:17), Cleaner on the DT100 and better vocal/instrument tonality and timbre. But a bit more detailed on the DT300.

Treble: Linkin Park – Shadow of the Day (03:24-03:42), electric guitars are sharper and more fatiguing on the DT100 but has better timbre.

Hiroyuki Sawano &Z (02:18-02:57), better tonality, timbre and clarity on the DT200.

Technicalities: Shiro Sagisu – Hundred years war (02:24-02:57), extremely similar soundstage. Imaging, separation and detail are a bit better on the DT200. Timbre and overall coherency are a lot better on the DT200.

Overall: The DT200 is cheaper, has better timbre/coherency, more technical and is better tuned….and this is with EQ on the DT300…. (Although the bass is better on the DT300, I give it that at least) …





Conclusion: You know…when I received this and listened to it the first time, I literally thought it was defective. Yeah, it is that bad. Went and confirmed it with another guy that also has it and it was confirmed to be the intended tuning. I proceeded to try it with an impedance adapter and it did improve it a lot, and yet it still had major problems (very recessed mids, peaky treble and upper-treble that would kill me). Then the last resort, EQ. Still lost against the cheaper brothers, the DT200 and the DT100….

Suffice to say I do NOT recommend this….

Audiosense, please try harder, you have 2 working recipes’ (DT100/200), why not use them?

Thanks for reading.
