AD900x vs AD900
The AD900x rectified all my past issues with the AD900. The new pads on these are significantly more plush and thicker. The drivers no longer sit or touch my ears. Also the felt material also improved. They are softer and not as rough as the past. Also the pads have more strength, they keep their puffiness. The AD900 pads would squish easily and the drivers would rest on my ears. Also the AD900x drivers are much more angled than before, which may help with the drivers not touching the ears. The AD900x also retain the AD900 treble and mids and that sweet sweet vocals. But there is immense improvement on the bass. The bass was always lively and tight on the AD900, but the AD900x just provides more of it. But it's still much softer compared to Monster bass headphones. I am very happy I purchased these AD900x. If you have never heard the Audio Technica signature sound or heard open air, I strongly suggest you hear for yourself before purchasing these. The amount of air, detail, fun and crisp sound is night and day compared to any closed headphones. If your experience with headphones are gaming headsets or Monster Beats or Bose, and you like that sound, you may not like the AD900x. But then your mind may also be blown away and fall in love with the magical sound of open air headphones.
AD900x remain a remarkably excellent sounding headphone and I challenge anyone to find a more comfortable pair of headphones. The 3D Wing can barely be felt on your head, but the clamp is just enough so the headphones don't move. The plush pads keep the pressure off your ears and the drivers touching your ears. These are simply the best headphones I've heard in my life so far.
