Takstar is a relatively unfamiliar manufacturer to me. Pro 82 was their first headphones that brought my attention because they seemed to be the headphone on Head-Fi at the time when i discovered them. I managed to find them for a good price from Aliexpress (50€ including shipping) and decided to give them a try.

After listening them for a few months i think im ready to give my honest, non-hyped review about them.

(Keep in mind that english is not my main language and there are probably few typos here and there, i try to correct them later)


Pro 82 comes in a very official looking case. To be honest i dont think is this level of luxury even necessary with 70-80€/$ headphone, heh. You might get robbed by carrying this thing around.

Box doesnt really include anything special besides headphones, manual, cable, warranty card, authenticity certification, carrying pouc, 3,5mm adapter and so on.

Design and build quality

Build quality is above average for the price in my opinion. They are mostly made of plastic but its not the cheapest plastic possible. Earcups are made of some sort of metal/aluminum just like headband adjustments which have also some plastic underneath. Headband feels very flexible. They have also removable cable like most headphones nowadays. They use the same connector that Sennheiser HD 500- and Audio Technica ATH-series uses. Build is probably slightly flimsier than M40X or something similar but they feel pretty durable overall. Pro 82 is also fairly portable, i would like them to have folding design but they are easy to carry around because of their light weight and compact size.

Design is pretty much ripped off from Sony MDR-1A and Audio Technica ATH-MSR7 but i have to say that i dig it more than their predecessors which was more Beyerdynamic-inspired. I like that they kept design plain and simple.

Comfort and isolation

I highly doubt that anyone would call these headphones uncomfortable. They are very light in weight and pads feel so soft against my ears that its sometimes hard to take them off. Zeos from Z Reviews said something like ”these are the first headphones that are so comfortable that taking them off makes my face feel less comfortable” and i can sort of agree with that, you can certainly wear these for hours without feeling any discomfort. Pads can start to feel a bit hot in warmer conditions and you may have to take them off from time to time just to let your ears cool off a bit but otherwise no complaints.

Isolation is also very good. They cancel ambient noise quite effectively just by wearing them and when you start to play music even at moderate volume its hard to hear much anything happening around you. People have been ringing my doorbell while im wearing these and i had no clue about that until they called me and asked me to open the door, lol.


Does Pro 82 live up to its hype in terms of sound?

(Some people claim that there are two(?) different versions available of these headphones, ”old” version and ”new” version. Only thing that seems to separate them from each other is the cable lenght, ”old” has 2.2m cable vs ”new” has 1.4m. Although there have been discussion about that they seem to have also a slight difference in sound quality. I cant say anything about that, my pair seems to be from the older batch.)

Pro 82 is quite balanced and neutral-ish sounding headphone with a slightly U-shaped signature meaning that low- and high-end is boosted a little bit. Ive found the overall sound signature pretty interesting because its kind of analytical and fun at the same time. These are being marketed as ”studio monitors” and while they probably manage that job better than many other headphones i think that they suit better for pure musical enjoyment, and i will tell you later why. There is certain type of mellow and lushy feeling to keep things interesting, its definitely not your typical ”flat monitor sound” but a bit more exciting. More casual listeners might find them sounding dull and too analytical but people who prefer detail and clarity over coloration will probably like these.

Talking about details, Pro 82 reveals surprising amounts of detail considering their price range. They are detail cannons. In certain songs i can hear things like guitar picks scratching against strings, fingers sliding across the fretboard, singer taking a breath before starting to sing, quiet hissing on the mix and other hidden tiny details in the background.

Clarity is also on a good level. Instruments that tend to sound sometimes a bit muddy with some headphones like guitars are clean and accurate. But at the same time clarity feels little artificial, like the headphone is trying to force as much clarity as possible. I dont always really get a feeling that im listening to real instruments. Overall sound coloration leans towards darker and warmer signature.

Ive also noticed that Pro 82 can be kind of picky about recordings, sometimes they sound almost perfect whereas some albums or tracks make my hand to reach for other headphones. Someone might call this transparency but i dont honestly think that its the case. Pro 82 sounds good to me overall but there is also some... issues.

Here is a graph from DIY-Audioheaven and it shows pretty much perfectly how Pro 82 sounds to me:

(I want to point out that my claims are not based on the graph only and that ive had long listening sessions during last few months and compared Pro 82 to many other headphones)


Bass is probably the starlight of the sound signature, its clean, accurate, and fast, maybe slightly above neutral in quantity. Very smooth and mellow sounding. Its not the most hard hitting bass though and people who are used to more bass-heavy headphones might find it lacking but i dont find myself carving more. Its just doing what its supposed to do, its not in-your-face but still very present in the sound signature. Mid- and upper bass have a pleasant punch and kick but bass does roll-off meaning that they cant reach the lowest lows. Sound signature is still very suitable for bass-oriented genres like EDM or hip hop, just dont expect anything crazy. Im actually a huge fan of the bass on these.

But it doesnt end there, Takstar were thinking people who want more and added bassports to the back of the headphones. As far as i know they are supposed to increase airflow to the aircups and give that way stronger bass response and it does work but not perfectly.

It has 3 levels that can be described as plenty of bass (closed) slightly more bass (opens a little hole) and way too much bass (opens a second bigger hole below that).

Second position gives a slight boost to the mid-bass (maybe little to the sub-bass as well) and slightly changes the sound signature. I like it in certain situations, it makes bass punch harder and adds more body and fullness to the overall sound and makes the overall listening experience more enjoyable and funnier to listen to. it can also help to solve some minor issues with these headphones (but more about that later). Third position is just... horrible. Bass starts to cover up everything and making the sound muddy and rumbling which makes them completely unlistenable to me. Sounds like some 12-year old decided to play with the EQ-settings. They probably should have added two little holes instead of one little and one big hole but its fortunately optional feature so im not going to complain about it. On the other hand even the second position is a bit too much for me in certain tracks.


Being U-shaped headphone mids dont necessarily stand out. I would actually almost call these borderline V-shaped headphones. Many reviewers have said that mids are a bit recessed and they can indeed sound little pushed down in certain spots making the whole midrange a bit non-present and unnatural sounding.

Lower midrange is only slightly recessed making mids lack body but not by much. This is where ive found the bassports to be very useful. I quickly noticed that with bassports closed guitars sounded a bit too grainy and tinny and didnt really stand out in certain rock- or metal tracks, opening the first bassport masks that quite well and adds more body to them. This helps also with male vocals which can sound sometimes a bit thin and distant/non-present because their voices dont have as much lower ”oomph” on them. Some people might argue that bassport ruin all the clarity and detail, maybe slightly so but mainly it just makes midrange sound just a tad more fuller and warmer (and off course pumps up the bass a bit). At least it makes certain songs much more enjoyable to listen to which is sometimes more important to me but im not saying that opening the ports will always sound good or that they are needed all the time.

Vocal clarity is also one stars of the show here, especially female vocals sound very pleasing and lively but they seem to lack upper vocal range a bit making their voices sound kind of lower or "thicker" than they really are. There can be some sibilance in the vocals but its usually very mild. Upper midrange seems to be more forward and can sound a bit piercing, i noticed that especially during my first listening sessions with Pro 82 but i dont really pay much attention to it anymore unless im listening on slightly higher volumes or longer periods of time, maybe im just getting used to it. There can be some noticeable graininess in certain tracks, that is most likely due to dip/fall at 2khz which gets covered by lower treble which gives upper midrange a bit muddy or distorted sound at times. This however is very track dependant. I think that this dip gives the midrange that sort of non-present feeling on it.

I would not call midrange as the strongest point of these headphones but energetic and detailed delivery of instruments (and bassports) still almost makes me forget it and for me its one of the main features that makes Pro 82 such a fun headphone to listen to. You might wont notice any of this on a daily listening without comparing them to other headphones with more even midrange.


Pro 82 has a powerful, very energitic and sparkly treble. Im not sure have i heard as much extending treble on any other headphone at this price range. I think that M40X is pretty comparable to it but because i dont have a pair on hand at the moment its hard to say.

But treble is kind of their curse and blessing. Treble is responsible of the energy and liveliness on the sound signature but at the same time it feels a little bit too aggressive and forced, almost overemphasized and sometimes it clearly effects even on the midrange in a negative way by covering parts of it. In top of that treble can sound metallic just like the upper midrange to the point that switching the song (or headphones) feels like a good idea. I like the energy and sparkliness on it but sometimes its just a bit too much. Its not always there but when it pops up its annoying enough. Bassports are sometimes the best way to calm down the treble a little bit.

Fortunately i havent noticed any serious sibilance, Pro 82 does pretty good job on avoiding it which is surprising considering how hyped the treble can sometimes be compared to other frequencies. But treble/midrange-ratio is not balanced enough for my liking, be aware that these headphones might annoy you at first in this area, at least they did it for me.


Soundstage is not obviously super wide (which is expected from a closed headphone) but what it lacks in width it fills with accuracy. Pro 82 has a very good sound separation/imaging which is so good at times that it makes the soundstage sound larger than it actually is giving you a ”out of head”-experience. I found myself constantly looking around me while listening because i heard something that sounded coming outside the headphones, lol. I think that their slightly angled drivers have something to do with this. They definitely deserve five stars in this area.

But there is a one strange thing ive noticed on it, sometimes the stereo imaging of Pro 82 can sound a bit imbalanced and give you an impression that the sound is leaning very slightly towards the left channel for example like the center image is missing. This seems to be very track dependant thing though, sometimes i can listen to whole album without noticing anything concrete but when it strikes its a bit confusing. Its even more noticeable when i started to compare Pro 82 to my other headphones. Someone would say that ”they are just true to the original mix” and maybe that is true, who knows. But i still find it somewhat strange that some tracks would be supposed to sound like that. Faulty pair came to my mind as well but ive found few other owners experiencing the same ”issue” so i dont really think that its the case. Not a dealbreaker for me but its sometimes a bit annoying. Maybe a manufacturing error? Extremely transparent stereo imaging? Just my imagination? I dont know.


Do they need any? In my opinion, no, not really. They go quite loud and have sounded good on pretty much any device ive connected them with and i didnt really notice any major differences between them including my phone, pc-motherboard and Creative AE-5. Off course they sounded better through Creative than a phone but not in a mind blowing way. This off course depends heavily on your equipment, if youre phone, pc or amp device is older or cheaper than mine you might find different results. I know that some people claim that Pro 82 benefits from a high quality dac/amp but i would recommend to take this claim with a grain of salt.

Genre pairing (coming soon)

Comparisons to other headphones (coming soon)


As much as i like the way Pro 82 sounds i still have to say that they are not perfect headphone to me even at this price range... but at the same time pretty close to it. I do think that their sound has some (minor) issues and i dont find them sounding phenomenal in every single track and they make me to reach for other headphones from time to time.

But i have still really enjoyed them enough that i would be lying by calling them a bad headphone, i think that they are a pretty unique sounding headphones and definitely one of the best sub-100€ closed backs ive tried and they are very comparable to many headphones costing about twice as much making them an excellent budget buy. Sure they have their own flaws but i can partially forgive them considering their price range

Are they ”pro monitors”? Im not an audio professional but i dont think so, they sound more like a toy than a tool to me. They are just too playful by their nature, yes, they are analytical and precise but more in a fun way. They sound kind of an combination of a monitor- and casual headphones. But if youre looking for a middle ground between the two i would not hesitate to give these a try. In top of that they are easy to drive, have amazing comfort and portability. These are my ”on the go”-headphones and im not afraid to wear them in public beacause they actually look quite nice as well. Im interested to see what Takstar is planning for their next flagship model, if they try a bit harder their next headphone might be 5/5 but Pro 82 deserves a very fair 4/5 from me.


500+ Head-Fier
Pros: Reference/monitor-sound for a very affordable price, Pleasant comfort, Carrying case + two sets of earpads and cables, Flexible build
Cons: Thin/recessed lower mids, A bit sharp and sibilant highs, Thicker pads start to feel hot during long listening sessions
NOTE: English is not my main language so i hope that you dont mind little typos here and there but i try to do my best to avoid them.

I havent heard of iSk until someone mentioned them and their HD9999-fheadphones on one tech forum. They are a relatively small and unknown brand originally from North America and as far as i know they are an OEM-manufacturer (meaning that they dont just rebrand products from other manufacturers). They are not really an headphone company and their main focus is on other studio equipments like microphones.

I were told that HD9999 are a pretty capable headphones for 60-70€/$ and owner compared them to this Beyerdynamic DT990s, a very reputable and famous headphones that cost double the price and said that in his opinion their sound is pretty close to them.

Off course i were pretty skeptic at first, how a company ive never heard of would make such a headphones especially at this price point. I checked Google and Youtube for reviews but i did find only 3 reviews in english including Head-Fi. I found that iSK-headphones are also pretty hard to find anywhere near where i live (Finland) but finally i found a store/seller from Aliexpress selling these for 60€ and decided to try them.

Because of lack of reviews i decided to tell my honest opinion about iSk HD9999 after using them for about an month.

Aliexpress seller:

Technical parameters (copied from Aliexpress):

Speaker Diameter: Φ50mm

Impedance: 32Ω

Sensitivity: 96dB ± 3dB

Frequency Response: 8Hz-30kHz

Maximum power: 1500mW

Cable length: about 3 meters

Plug: Φ3.5mm + Φ6.3m


They offer a nice carrying case with them. Its made of hard plastic and it feels pretty high quality, very nice that they included it. The seller also offered headphones with accessories only without the case which decreases the price a little bit but i wanted some ”eyecandy” to my shelf.

Inside the case you will find good amount of accessories including basic things like a manual and 3,5mm-to-6,3mm-adapter. What really satisfies me is that they included two cables (cable is removable), straight long cable and coiled shorter one. I tend to break my cables too often so now i dont have to order new ones instantly, thank you very much for these. I use the shorter one since its easier to keep them away and my desktop is already a disaster when it comes to cables. They use the same XLR-connector as AKG-headphones so even if you manage to destroy both of them finding a new ones is not a problem.

They also include a two pairs of earpads: they come installed with pretty high quality thick pads that feels extremely soft, almost like tiny (fake)leather earpillows. I want a pillow made of this material some day. Second ones are thinner and feel a bit cheap and harder on the head compared to them and i have to say that i prefer the thicker ones. I still appreciate that they included them, not too many headphone manufacturers do that.

Build and design

First thing you probably notice is that HD9999 looks exactly like AKG-headphones. I mean, change the branding and no one couldnt notice the difference when it comes to looks.They might look a bit bulky and heavy at first but in reality they are surprisingly light in weight and they dont feel like a helmet on your head.

”Beauty is in the eye of the beholder” but i really like ”black and gold”-combo and AKG-style ”retrodesign”, they resemble me of AKG K240 which has probably inspired the design of these headphones.

They dont feel too cheap despite being mostly made of plastics with some metal finish around the earcups and on side of the bands as well. Those ”taps” on the earcups with text on them feel a bit cheap and that you can rip them off with a little effort but as long as they stay there during normal usage im not complaining about it. Not the sturdiest headphones out there, but they have a very flexible structure, you can actually bend these to a pretty awkward positions if you want to. They dont have a one adjustable band like most headphones do, instead of that they have the same kind of autoadjusting headband that is found in many AKG-headphones; earcups are connected to plastic-covered metal wires and a rubber ribbon.


Fit and comfort

While not being the most comfortable headphones ive tried with the thicker pads these definitely belong to the upper end. Thicker pads almost melt on your head like pressing your head against a pillow. Thanks to autoadjusting-mechanism wearing them is very smooth and i dont really feel need for further adjustments, sometimes i have to swivel the earcups for a little better fit.

Downside is that thicker pads can start to feel a bit hot after wearing them for a long periods of time but were talking about pretty long listening sessions, i may have to take them off once or twice in 1-2 hours to let my ears cool a bit but i dont think that its a problem in shorter sessions. Of course there is an option to change the earpads and experiment with different pads to make them more suitable for a long term usage.

Sound quality:

And finally the main thing, sound quality. As a monitor type of headphones HD9999s are fairly neutral, uncolored and analytical compared to more ”fun/relaxed” sounding headphones which can take some time to get used to if youre more familiar with ”casual-ish”sound signature. I would describe the sound to be clear, accurate and detailed with tint of warmth. Its certainly not ear-pleasantly smooth but not overly analytically harsh either but somewhere between them. Like a compromise between a strict studio session and a chilling jam on a bedroom although they lean a bit more towards the first one. To my ears they are not also very unforgiving for poorly recored/poor source materials but that can be expected from a monitor headphones.

I have used HD9999 mainly with thicker pads and i only quickly tested the thinner pads so i cant give a very accurate comparison and because of that review is based on thicker ones. Also keep in mind that the type of dac or an amplifier youre using might give you slightly different results, ive used these headphones with my Creative AE-5-soundcard.


I actually really like the bass on these. With the thicker pads bass is slightly too emphasized to be described as completely neutral but its still very neutral compared to some all-about-bass-headphones out there. Its not the most tight or punchy bass which im not a big fan anyway (too thumpy bass almost makes my head hurt after listening for a while), its more softer type of bass and pretty well controlled. Sub-bass growls low and mid bass do give you a decent midbass punch when needed but dont expect these to be crazy bass cannons. But when using thicker pads these can be classified as a slightly bass-heavy headphones.

I enjoy listening to bass oriented music with these like electronics, R&B, funk etc. Bass is probably one of the strongest points of these headphones but im not a basshead so i cant say is it enough for someone who wants a lots of bass.


HD9999 is clearly a V-shaped headphone (meaning that the lower and higher frequencies are slightly more pronounced than the mids) and to me mids are clearly the area where it sometimes struggles. Even if the mids are a bit recessed compared to other frequencies they are still presented accurately. Upper mids are quite good, all instruments from guitars to wind- and string instruments sound clear and detailed and female (and higher male) vocals sound clearly articulated, bright and slightly warm.

I can hear little ”ringiness” in the upper end, escpecially in high pitched vocals, kind of a resonance. Its hard to explain, but imagine that your watching a live show in the front row standing right next to speakers and you can kind of feel higher pitches go ”through your head”, i hope you get it. But these are made to give you a honest and lurid monitoring-type of sound so i cant really complain about that, thats kind of how their supposed to sound like. Besides the amount of that ringiness/resonance really depends on the track youre listening to. As i said, these are pretty unforgiving headphones. And if i really want to enjoy vocals or mids in general HD9999 wouldnt be my first choice anyway.

For me upper mids sound better than lower mids, in the lower end male vocals and heavy distorted guitars for example can sound a bit hollow and thin in comparison to upper mids and when listening to more downtuned and heavier genres like metal music guitars seem to kind of lack body and that chunky sound you need for that kind of music. Dont get me wrong, its not too serious and wont ruin overall experience with these headphones but its the reason why these headphones are not usually my first choice for listening to heavier metal music, of course it could be a lot worse too.

My feelings towards the midrange in these are pretty mixed, for me there is probably just as much things to like as to dislike. Maybe im just too used to my old trusty HD 598s always-so-smooth mids but their midrange is probably one of the best out there so i cant really compare them to HD9999. Midrange performance is a bit inconsistent but it still has its good moments as well.


HD9999 propose highs most of the time very well with great clarity and detail creating that bright and clear sound signature. But when going very high sometimes they tend to be a bit sharp and sibilant in a way what almost hurted my ears when i used them for the first time but im getting used to it so its not that bad anymore.Just like the resonance in the upper mids this is also a very track depending thing. Highs are more consistent than mids but i would prefer them to be a bit smoother.

Treble does roll-off in the very highest frequencies so youre not getting the most highest or detailed highs but still very bright sounding headphone overall. Not the best choice for treble-heavy music or treble-sensitive ears in my opinion. I still like that brightness they give for certain genres like trance and other EDMs.


Better than in most of the closed-back headphones that ive tried. Not competing with open-backs but still pretty good. Thanks to wider soundstage i found these performing surprisingly well in gaming.


Perfect headphones dont exist to me; there is (almost) always something you can improve and HD9999 is not an exception to this. Despite their small shortcomings i really do like the overall sound in them. But at the same time i think that they wont probably suit for everyone. As i mentioned before they are not the most ”fun” or ”musical” sounding headphones out there and in my opinion they are clearly made for specific type of listening. Podcasting, mixing, producing, even some gaming or basicly anything that requires you to hear everything as clear and accurate as possible.

Im not saying that music dont sound great through these headphones, thats my main purpose for them. Certain songs and genres sound better than the others, at least for me they are kind of a ”niche pick” when it comes to music, but when you really find that sweet spot its a very enjoyable experience, though sound signature still might not be right for everyone. Live recordings, instrumentals, electronic music, these are in my opinion the occasions where these headphones really start to shine. I listen my electronics mainly with these and they are probably my best headphones for that purpose but maybe not for someone else. After all ”good sound quality” is so subjective thing that i cant say for sure are these headphones for you but i hope this review helps you to make decisions.

HD9999 were a positive surprise and i have really enjoyed them so far and will certainly keep them. They are not perfect choice for everything but my other headphones are not either. For roughly 60€ (or 55€ if you minus the case) there is really nothing major to complain about and i can honestly say that these headphones offer more than enough for that money, way more than an average pair of 60€ headphones. I cant say anything about that DT990-comparison because i havent never tried them but i think that these cant be too far away. ISK is going to the right direction with these headphones and i can recommend to give these a try.
