I noticed the ATH-A900X is very under-reviewed on the English-speaking side of the world. Not just by users but by professionals as well (there is only one professional review of the ATH-A900X written in English, and that is by an European website - there are no American reviewers who's looked at these cans). This is rather strange to me, since Audio Technica isn't exactly a small or unpopular brand.
My guess is that most people go directly for the ATH-M50 when it comes buying sub-$200 AT cans. But they really could be going for the A900X instead!
So, I am getting the good words out - the ATH-A900X, in my opinion, is a very solid performer with great comfort, build quality, and usage versatility:
The Audio-Technica ATH-A900X and its Frequency Response Measurements (measured by GoldenEars)
- Excellent treble clarity and extension.
- Warm and full-bodied mid-range.
- Boosted mid-bass great for games and movies.
- Great soundstage and imaging due to the good treble resolution.
- Very comfortable (assuming you don't have issues with Audio Technica's headband wings).
- Bass extension isn't great, and the mid-bass boost can be a bit much depending on content (can be solved by installing different earpads).
- Comfort can be an issue if you have a narrow/small head, or if you just never liked Audio-Technica's wings in general. The clamping force on the A900X is fairly strong for my head size, and it doesn't slide around at all - but many users reported it sliding down onto their ears due to the wings not having sufficient down force.
ATH-A1000 Earpads Mod
The A1000 earpads are fully compatible with the A900X, and alters its sound signature by reducing the bass (the opening is oval on the A1000 versus the round one on the A900X stock pads. Smaller opening = less air = less bass).

Feel free to share your own experiences with ATH-A900X, ask questions, or do your own comparisons with other cans you own.
