Product Features:

  • Sealed-back construction offers mild isolation and excellent listening privacy
  • 53mm drivers are amongst the largest in the industry for maximum clarity and musical impact
  • Excellent detail resolution and musical definition
  • Uber-comfortable for a full-size closed-back audiophile headphone


Finally available in North America from Japan, the Audio-Technica ATH-A900 is a closed-back, full-size headphone delivering signature AT spaciousness of sound and a comfortable fit that's made them world-famous in audiophile headphone circles. Encasing extremely large 53mm dynamic drivers and CCAW voice coils, the A900's circumaural earcups fully encircle the ears and offer mild isolation that is not total, so intent listeners can remain somewhat aware of their surroundings if need be. The sound of the A900 has a robust low bass delivery that segues into present if slightly laid-back mids and nasally highs; in other words, a good candidate for classical and symphonic recordings full of lively instrumental passages and acoustic 'room sound' depth. The soundstage is acceptably wide and deeply layered, again a great characteristic for chorale and orchestral music genres most especially. Rock and rap fans may perhaps want a bit faster, more crunchy sound and bigger mid-bass texture but listeners into varied genres will definitely find something to seriously enjoy about the ATH-A900.

The Audio-Technica ATH-A900 has true "around-the-ear' (circumaural) earcup dimensions, meaning its a fairly big headphone designed for home and office listening. AT's proprietary "3-D wing" construction has some of the best wearing ergonomics found in full-size headphones. Although the A900 are efficient enough to be used without any amplification, a dedicated headphone amp audibly improves detail resolution and timbral accuracy / transparency in our subjective listening tests. Please allow about 200-300hrs of play-time (aka 'burn-in") for these headphones to fully break-in and sound their very best as they can be slightly "brittle" sounding right out of the box. The ATH-A900 cord extends about 10ft in length and terminates to a high-quality stereo plug. Manufactured and engineered exclusively in Japan.

Great for beginner audiophiles!
Posted by bluescribe from Evanston, IL on 2011-06-07

Recommend Product: Yes
Pros: Detail, broad soundstage, comfortable
Cons: Slightly sibilant w/o amp, slightly subdued mids, cheap materials

Directly out of the box, I have to admit I wasn't too impressed with these cans. The highs were very hissy and the bass was barely pronounced, let alone visceral (I usually like to "feel" my bass a bit). However, after I let them burn in for a couple nights, they started sounding better and better.

Eventually (after about three days of consistent listening and three nights of burning), the sound I got from them was INCREDIBLY detailed and pretty balanced. For golden ears who like to hear "the wind between the strings" of instruments, these cans have you covered. While their slight sibilance in highs can get a bit taxing on the ears, it's so pleasant to hear the detail that sibilance adds. As soon as I amped them (keep in mind I have a relatively cheap, portable amp) the bass and mids were brought up to speed and the sibilant edges of the highs were significantly smoothed out. I still wish I could have more mids, but I think I'm going to have to wait until I can afford more accurate cans.

A note on the materials: they're pretty cheap. The earpads are covered in a crinkly, trash bag-like material that I know is bound to tear at some point. The rest of the phones are all plastic. The little pads that secure the phones on your head have a nice silky material, but the pads themselves aren't secured to the rest of the headphone, so they fall off quite frequently and could get lost.

Due to the lack of durability and the size of these babies (they're HUGE; they cover almost the whole side of my head, granted I have a pretty small head), these definitely aren't the kind of headphones you want to be carting around. However, if you keep them on hand as a go-to pair for home listening and take good care of them, they're actually quite comfortable.

Overall, your money is pretty well spent on these. Their sound really grew on me, especially the broad soundstage and the nice detail. If you can shell out for a higher end, more durable headphone, then I'd say go ahead. However, I'm a college student on a tight budget, and these satisfy my audiophile cravings quite well for the time being.
