Currently the finest Headphones in my inventory. Also I just noticed your comment and my lapse to MAKE A REVIEW on SOUND QUALITY and Impressions. Oh dear heaven. Well the news in the short run is I adore the SQ, the size, shape, comfort, fit, everything about them. Except the dinky stock cord. I sent them in to an Audiotailor to have them Recabled. I listened to them recabled and they're even NICER than with the stock cables, which are small guage and puny IMHO. I'm speaking about the actual wire. The conductor on the Recable is 6N UPOCC Copper 24 AWG stuff, quite nice. There was one complaint I had about the jack I selected and one flaw in the strain relief, so they are bounced back to the Recabler's for refit ATM. No big deal. Audio Quality is just as stunning as Stock ATH-ESW9A, with a bit more clarity, resolution, and bass extension. I approve. I should be getting them back before the San Francisco Bay Area February 19th Head-Fi Meetup so I'll really get to test their salt with lots of different gear.
BTW, I've adopted some of the tricks of the Ortho Roundup folks and applied some Damping schemes to my ATH-ESW9A's, some Open Cell Foam, with a layer of Durapore Tape to damp sound reflections, and in the Earpad, some layers of Felt to enhance the Bass, and darken the sound signature a tad, as well as a layer of Sponge a la Grado Bowls to bring out the treble resolution seperation below the Earpads, in front of the Drivers.
They sound great with the additional pieces of kit stacked in.
I'll have to do a more qualitative analysis when I have more time.
