Rated 2 out of 5 by X1User They are OK
Overall, they are not bad for the price. The main issues with the sound is that the bass is a little loose and can muddy things up. The highs are also rolled off and lack some clarity.
The earcups also started leaving stains if you left them on your desk atop paper.

Rated 5 out of 5 by spin Amazing headphones! Pristine sound quality.
WOW! They're THAT good. Nearly perfect performance. I wouldn't be giving a fair review if I didn't mention the lack of sound isolation, however, we all know that open-back design trades off sound isolation for more natural, unrestricted sound from nearly all audible frequencies. So they're not perfect for travel or jamming to Classic Rock in close proximity to other people. There are plenty of good isolation and/or noise canceling cans and earbuds out there that fill that roll.
What they do offer is a beautiful frequency response (10 to 40000 Hz), minimal (negligible) total harmonic distortion (<0.1%), low impedance (30 Ohm ... so you really do not need an amplifier), sweet 50mm neodymium drivers angled to send the sound directly through the external auditory canal and onward to the tympanic membranes (ear drums), and a very manageable and comfortable weight of 0.661 US Pounds == 300 grams.
The ear cups rest well over the ear with room to spare, and the pads are made from a silky soft foam covered by a black velour cloth. I have worn them with no discomfort, sweat, or complaint for over 12 hours. Simple, elegant, refined, top-shelf, brilliantly engineered, comfy -- these are some words that jump immediately to mind following ~250 hours of use thus far. That's only a small amount over the controversial "break-in" time of 200 hours that many audiophiles feel is necessary before the drivers are playing at their optimum level. These headphones have sounded perfect to me from the start, to now. I listen to non-transcoded FLAC and a little Internet radio as well. I listen to all genres: from Classical / Baroque, to Jazz, to Thrash Metal, and back again. I hear many thing in my music that I have never heard before ... like the sound of the drumstick striking the ride cymbal near the dome (again, I hear not only the cymbal, but the stick striking the cymbal). I am a drummer, and this stick-click is something I have heard ONLY while playing my drum kit. The sound is so immersive and intricate, the stage plays very large; YET, with any instrument being played, it feels like you could play that same instrument as though it were directly in-front of, or all around you (like Neil Peart playing his 360º custom drum kit. I also have heard the vocalist's lips or tongue click as they were singing, perhaps due to a bit of cottonmouth.
Lastly, I have a very large head. The breathable air-foam-mesh hammock with elastic self-adjustment help cradle the top of your head with outstanding comfort and zero excessive pressure points. In fact, once the headphones are in place, you will likely not even notice the foam-mesh hammock. They fit me perfectly. There is ample grip on/around your ears, but none of the grip pressures feel unpleasant to me.
What a wonderful amount of aural pleasure I look forward to for many years to come. I recommend these headphones without hesitation or reservation. I hope that you enjoy your set as much as I am enjoying my X1/28 Fidelio™ Headphones, by Philips®.
