    Best Closed-Back Headphones I have ever owned!


    These Headphones are absolutely amazing! Honestly the best I have even owned! Great sound quality and sound stage! Bass is really good as well. I was a bit of a bass head but since I have had these, I can hear more sound which has made me respect the mids and highs more. The only downside to these is due to my big ears. The cushions sit on my ears and since there is a fair amount of clamping force, they hurt my ears after about 3 hours of continuous use.

    Nice Cans!!


    I've owned these 'phones since 2012 and have used them in a variety of ways (television via A/V receiver, music via A/V receiver, music via iPod - plugged into a headphone amp, and most recently directly into a Pono player - best vehicle yet!). The sound is balanced...not too much bass/mid/treble. The are quite comfortable; however after a few hours of use they wear a bit 'warm/hot' on the ears/head...not a big deal, but no device is perfect. Given the initial cost and quality of these 'phones, I can only give my highest recommendation for the ATH-A900x.

    It is a good headphone but the quality varies


    The sound quality of this headphone is amazingly good when I listened to most of music with it. But when I listen to an audiophile test music of drum, I found that one side of headphone was good , but the other one had a resonance vibrational noise at a deep bass. Because the other side was still very good, I have asked for a replacement in stead of returning. I wish that Audio -technica had tested each of their headphones carefully in the whole frequency range as most of customers may not have the test music as I do to find out this problem. I think the technology behind this headphone is good, but if a screw were not tightened enough during the assembling, the sound quality will get worse.

    Great sound quality


    I recently picked up a pair of ATH A900X headphones and I have to say that I am very impressed. The sound quality is phenomenal on these cans right out of the box. I'll break it down a bit for those interested in getting these great headphones. Comfort 3/5 These headphones are insanely comfortable for me personally. The 3D wing system is great, I can wear the headphones for hours without taking them off. Initially the pads are slightly stiff, but after some time with them they have softened up a bit and feel great. I give them a 3/5 because the comfort is not across the board, these headphones are not for everyone in terms of comfort. My girlfriend for example cannot wear them because they are simply to big and slide down her ears. Having a bigger head is definitely a plus with them. Build quality 4/5 The build quality feels nice on these headphones. The aluminum housing is nice and although most of the frame is plastic, it feels built to last. The nylon wrapped chord is especially nice is very pliable and the metal plug is very sturdy, great quality here. Highs 4/5 The highs on these cans are great, almost no sibilance, they aren't piercing at all and also not fatiguing. I don't listen to classical much, but for testing purposes it sounds great to my ears. Mids 5/5 Audio Technica has the mids down pat on most if not all of their audiophile headphones, these are no exception. Vocals sound fantastic, you can't find many headphones in this range with mids this good. Lows/Bass 4/5 Most of the previous line of headphones in the audiophile section for AT have been a bit lacking on the low end, I can't say the same for these cans. These aren't "bass head" headphones, so you won't hear crazy pounding bass from them. What you do get is a nice smooth presence in the low end. The bass is tight, and it comes with a nice punch. A definite increase in the low end of the spectrum compared with some other AT offerings. I should mention that the headphones definitely are not portable. While they sit snug on my head, I would not to want to go for a run with them or take them with me on a bus. Definitely an "in your house" style listening experience. They are also an easy to drive 42 Ohm headphone, so they sound great straight out of a mobile device, laptop, desktop, etc. Amp's and dac's can always add to them, but aren't required.

    I don't often wear headphones but when I do, I now prefer Au


    I have only owned a few pairs of headphones over the years, I can't stand 'em. I can't stand having this "thing" clamped or sitting on my head. The muffed effect on the ears drives me crazy. I also do not like being unaware of my surroundings. My favorite before this last decade was KOSS, I just loved the sound, but I could never get used to it. I have tried other brands, different types perhaps. The last best stab I made at it was a pair of Sennheiser RF wireless headphones. Now I know they were not the higher end stuff but I figured the name should get me some quality. However the sound to me was very dry, almost starchy and very shallow. Now, I let them break - in a bit, but I think I was stuck with the sound, and I didn't like it. So, I sold them and said to myself, once again "some other day maybe I'll find the right pair for me". The occasion arose to where I was going to need headphones as there was going to be visitors in the house. I'm a night owl, but my guests are early to bed and I needed to cut the sound level at night. So I continued my ongoing research and window shopping sprees on line. I had my eye on the Sennheiser HD line such as the HD595. However the more I poked around the forums the more good things I heard about Audio Technica.. Of course the ATH-M50's were the standard issue, and if I went with Audio Technica those were the ones I would go with. So it was basically between the HD595's and the ATH-M50's. Audio Technicas' audiophile line always looked interesting to me and I was willing to try them, but did not really know what to expect. Push came to shove and of all the models ( including limited editions, ect.) and all of the prices started to spell their-selves out. One day I saw the ATH-A900x for auction on e bay. it was the last 5 minutes and I did not intend to snipe, but the price vs the model could not be resisted. I got a brand new pair of these for $85, an absolute, complete steal... I have liked these headphones from the second I ripped open the box in anticipation. I have so far loved everything about them. The fit, the feel. Very high quality build, the cans are aluminum but the joints are made of plastic, but I can tell it's all quality and built to last. the self adjusting support is awesome. I have a fairly large head and these fit me like a glove. You just put them over your head until the pads are over your ears and just never think twice about it again. I feel comfortable in these and it is mostly the sound quality that I keep putting them on for. The feel is very comfortable. I can tell I have them on but it doesn't bother me. There is a slight weight to them and slightly warm over the ears, sometimes. The sound however is what a quality pair of headphones should be. Full, rich, deep and smooth. When the volume is turned up the sound maintains it's perfection. Every sound is isolated and there is a seemingly endless reveal, yet it all speaks from one heart, the joy and love of music and sound. Yes, I feel I have a truly audiophile experience, every time I ware these. They are also excellent for movies and TV. "The Island was on TBS tonight and the sound is amazing, detailed, and very realistic. The sound stage is deep and 360 degrees of bliss. As I finished off the movie with some electronic dance stuff and had to write this review. the only weakness I have come across so far is, the the solo on Carcass' "reek of" track 7. the sound breaks up a bit during the solo, but few speakers pass that test. These phones are also excellent for Metal. The more I use these the more I like them. Both sound quality and fit are excellent. For the first time in my life I can honestly say it is a pure joy to wear these Audio - Technica ATH-A900x Art Monitor Audiophile Headphones. thanks, your costumer for life!

  • Q & A

    I need replacement wings for the headband portion of my Audio-Technica ATH-A900X headphones. These are the padded pieces that rest on your skull. Do you know where I can acquire these? OR is there a replacement headband that will work?

    Adam P

    Please contact our Parts Department at (330) 686-2600 ext 5002 or at for assistance with this.


    I have a 2 questions. 1. How can i check my headphones about if they are the original one not the fake replacement? 2. What would you suggest use to get full potencial from them? Atm i have soundcard sc808 with 3x muses02 and fiio e17 as mobility one.


    To provide you with the best possible answer/support, please contact the Audio-Technica division for your world area: Thanks!


    I see in an answer from a little over a year ago that there were no plans to discontinue the ATH-A900x in the U.S., yet it is still impossible to find through authorized retailers. Will we ever see this in stock from an authorized retailer anywhere in the U.S. again?


    Thank you for your inquiry. These have been shipping and are very popular, so they do not stay in inventory very long.


    600 ohm version vs. 38 ohm version Ad900x? Dear Sir, I want to know,if the 38ohm version of the 900x headphone,has any difference in sound quality,from,the 600ohm version? Any help/suggestions,will be greatly appreciated. I already own ,the 38 ohm version. Many Thanks, Mike


    Unfortunately, Audio-Technica United States does not offer any 600 Ohm headphones, let alone a high-impedance version of the ATH-A900x / ATH-AD900x / ATH-A900 / ATH-AD900. (ATH-A900x) (ATH-AD900X) (ATH-A900) (ATH-AD900) If you have any further questions, concerns, or comments, please email the ATUS Audio Solutions Department at Thanks!


    Ear Pad size What size are the 900x ear pads, I am looking to get a velour replacement.


    Thank you for your inquiry. The velour earpads featured with the ATH-A700 will also work with the ATH-A900x. If you would like to order those, you may do so through the Audio-Technica Parts Department


    A successor model in the near future? Ive been looking into buying a pair of full-sized cans and amidst my research ive decided on these. However the only thing stopping me from purchasing is whether or not these will be replaced by a newer model, seeing as how I find a lot of "discontinued by manufacturer" on retail sites like amazon. If so will it be similar to how the m50x's being the successor to the m50s but with a detachable cable? Thanks in advance.


    Great question. Unfortunately, the information about the ATH-A900x you received is incorrect. THE ATH-900X ARE NOT DISCONTINUED; they are still a current Audio-Technica United States (ATUS) product, with no current plans to discontinue them. It is important to note, when purchasing any Audio-Technica product, it is always best to purchase from an Authorized ATUS Dealer, which is both located in the United States and ships directly from the United States. This will both ensure product authenticity, and qualify you for the ATUS Warranty. Below is a list of consumer dealers that you may purchase Audio-Technica High-Fidelity headphones from, including the ATH-A900x headphones: - - Beach Camera - Walmart - Radio-Shack - Staples Subsequently, purchasing from a vendor located outside of the United States will disqualify one for the ATUS warranty, and makes it extremely difficult to verify product authenticity. Below is a link to a list of dealers to avoid: I hope you find this information helpful and informative. If you have any further questions, please contact the ATUS Audio Solutions Team at Thanks!


    Headphone Earpad Duribility So I had these headphones for a year and they are amazing. One thing though is that the ear pads started to wear away about 2 months ago, and by now the 'leather' is all worn away. I still get pieces falling off every night after use, they end up sticking to my cheek or something odd. The ear pad just keeps withering away and my headphones are kept in perfect condition. No oils from hair or anything were overly exposed to cause this effect. I put probably 1500 hours of use with these headphones though so that might be the case


    To replace the earpads, please contact the Audio-Technica United States (ATUS) Parts Department at A few comments: -The earpad material is NOT leather. Rather, it is Polyurethane based we refer to as Leatherette. - To clean Audio-Technica headphones, it is recommended that one first disconnects the headphones from any and all devices. To clean, use a dampened cloth with a small amount of soap or mild detergent and water. Do NOT soak the headphones with ANY liquid, be it water, cleaning-solution, etc. Simply use the dampened cloth to wipe down the headphones. Please make certain that you do NOT use a soap or detergent that is known to irritate your skin, and avoid using any products containing any amount Bleach, Alcohol, or Ammonia, as they could dry-out and/or damage the material. It is recommended that you try on an inconspicuous area first, before attempting to clean the rest of the headphones. After using the soap or detergent and water, please wipe down with a water-dampened cloth. Regular cleaning will help to preserve the earcups. Thanks!


    Bass questions I've been doing a lot of research on what kind of high end headphone I want, and I thought I had settled on this product right here. Unfortunately I've read an article on Head-Fi about the ATH A-900X, which presented a very stark contrast to what I had read here on the site. One of the biggest questions I have is, do these headphones have the kind of bass I want? I'm an audiophile, not a bass-head, but I definitely don't want to skimp on bass, since it's one of the most exciting parts of some of the songs I listen to. I want a very warm sound in my headphones, but I want the bass response to be very quick, as well as all the other ranges to be able to be heard over the bass.


    Thank you for your inquiry. You ask a hard question because "bass heavy" is very subjective. If I could quote one review of these headphones that I agree with: "These aren't "bass head" headphones, so you won't hear crazy pounding bass from them. What you do get is a nice smooth presence in the low end. The bass is tight, and it comes with a nice punch."


    Can I change ear pads? Hi... I'm looking for an even more comfortable fit with the a900x. I've read the ATH HP-A1000 replacement pads may be a good option. So can I use these? If so... would I need a professional help or It's something can be done by ourselves as costumers? thank you very much in advance


    The velour earpads featured with the ATH-A700 will also work with the ATH-A900x. If you would like to order those, you may do so through the Audio-Technica Parts Department Thanks!


    detachable cable I was able to have a quick audition of this headphone, and was very pleased with the sound. I noticed that the A900X is not equipped with a detachable cable, which is often one of the 1st problems encountered with headphones. I was wondering what kind of warranty is offered on the wire, or if there is a version with a detachable cable.
