Pros: Excellent build quality, comfortable, airy soundstage, mid colouration beautiful for female vocals
Cons: Bass still not linear, may lack transparency for some
The below review is a summary of a full comparison of the AD1000X to the AD900X and Sony MA900 found here:
I also made a Youtube review of the AD1000X. If you like the video check out my channel for more reviews! :)
The AD1000X has fantastic build quality with a magensium alloy frame. The 3D wing design is comfortable, though it does not work for everyone's head. The AD1000X features angled velour earpads that are quite comfortable. The angle helps the headphones conform to the shape of the skull. The AD1000X has a double entry cable unlike the AD900X. I actually prefer single entry cables but from a balanced channel design standpoint I suppose this is a good thing.
The AD1000X is actually quite different in signature from the AD900X, and in many ways reminds me of a less extreme version of the AD2000 (which was beautiful but could sound honky and grainy at times). First off, the AD1000X does not have the same sense of transparency that the AD900X has. It sounds immediately like a headphone that has been tweaked for a particular signature, with particular emphasis on two sections: an upper bass peak that gives everything a sense of solidity and punch, as well as a lower treble peak that emphasises the breathiness of female vocals and gives everything an emotive and exciting tone. To me the AD1000X has a beautiful and engaging tuning, and actually sounds a little less clinical and dry than the AD900X. It’s liquid and extended (but never harsh). What is also very immediately obvious is that the AD1000X does not have the same incoherency that the AD900X could have at times. The AD1000X sounds laser beam clean, and things just pop and burst on the soundstage.
I think the AD1000X is a pretty fantastic package, though it is definitely classic Audio Technica with a tuning that may not appeal to everyone. It sounds clean without sounding boring, and has great build quality to boot. For the current Amazon Japan pricing I would strongly recommend it to anyone after an airy, atmospheric and exciting headphone!
