Hello everyone! I noticed this particular pair of headphones 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 frankly rather strange to me, since Audio-Technica isn't exactly a small or unpopular brand, and their sound signature, to me, shouldn't have trouble acquiring a market in the mainstream.
So, I am getting the good words out - the ATH-A900X, in my opinion, is a very solid choice for both music lovers and movie-watchers/gamers alike in the sub-$300 category. It is a very well-rounded package and has great genre versatility:
The Audio-Technica ATH-A900X and its Frequency Response Measurements (measured by DigitalVersus)
- Beautiful, detailed, and sparkly treble with very good extension, but not sharp or sibilant! Treble on the A900X is perfectly presented in my opinion.
- Warm, detailed, full-bodied, and engaging mids. Vocals and instruments sound clear, intimate, rich, and lively, but the mids are not so colored as to sound unnatural or artificial. Very well-balanced.
- Bass has good extension and volume. There is a peak between 60-200Hz, which makes it very good for bass-heavy genres and movies/games.
- Sound stage is extremely wide (especially for closed cans), with superb sound positioning and depth depiction. Instrument separation is likewise excellent (thanks to crystal-clear treble and mids).
- Very comfortable (assuming you don't have prior issues with Audio-Technica's wings system).
- The mid-bass peak can be annoying to those who don't like bass emphasis or feel uncomfortable from high bass volumes (like me). Easily remedied with equalizers, though.
- 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 downforce.
Feel free to share your own experiences with ATH-A900X, ask questions, or do your own comparisons with other cans you own.
Also, we should gather together and request some professional review sites to review the ATH-A900X! I already sent in a request to Headfonia, though I am not sure how to get through to InnerFidelity. I think these headphones are excellent and deserve more exposure.
