Audio Technica ATH-W1000X

It took me a while to warm up to this set of ATH-W1000X, because they are just so warm compared to what I'm used to, so it sounded like they lacked the clarity of my other sets (which, to be fair, are excellent and very expensive sets such as the Beyerdynamic T1 and the open ATH-AD2000X) - but it's not that the clarity is lacking, it's just that your ears are full of warmth and you don't notice that EVERY detail is there. My title, pros and cons say it all really - it is not a cheap set, but I firmly believe that they're the best closed headphones under $1000 I've heard, so given that, they're a steal at about $450 US/$550 AU. If you are really savvy, you can get them cheaper, so that's a REAL STEAL then.
Sound staging is actually better than many open sets I've heard, including ANY Sennheisers (HD650s come to mind for a closed sound from an open set), and similar staging to the ATH-AD900, which is saying something.
A great set of headphones, without a doubt.

I bought a pair of these recently, I'm one of many who took advantage of the $399 deal on these.  I think for the price I paid they are a pretty good deal, but they do have some issues.  They are certainly an attractive pair of headphones.  Cable looks and feels a bit cheap, but the 1/4" plug is quite nice.  To me these sound a lot like my D7000s, although certainly not as good, pretty close overall.  They have robust bass response, although it lacks some extension and can sound a bit muddy at times.  I found the midrange on these not quite as good as others describe, to me it sounded a bit strange.  The highs on these seemed a bit dull to me.  They do have a very "musical" (sorry) sound to them, which is what I find appealing about them.  They are very forgiving of poor recordings and sound pretty good with everything.  I did many side by side comparisons/litens with my Pro 900s.  The 900s have a reputation for having a blurry and recessed midrange, but to me they sounded just a bit more clear/crisp than the W1000s and overall I decided to sell them for that reason, since I only wanted one pair of headphones in this price range.  I must also say as many have before, the headband adjustment, or lack of, is really frustrating.  If you move around too much they move around too, not a fan of this at all.  Overall I would have to say I definitely recommend them for someone looking for a pair of headphones in this price range.

Bought my ATH-W1000X headphones used, with leather earcups and an improved cable.  Using a Linn Mimik CD Player and an older Woo WA-3 with Amperex (Holland) tubes, and getting what I consider exceptional sound for from dynamic drivers.  I also use a Stax Sigma with a Stax SRT-1W amp/preamp, and the Audio Technica 'phones come reasonablyly close to the Sigmas through the Woo amp.  I listen to classical and jazz both through speakers and headphones, and I'm quite please with both the sound and feel of the ATH-W1000X's.
