    Superb!

    Excellent headphone. Attenuate a couple of treble bumps and boost subbass a pinch and it is an HD600 killer and superb monitoring/mixing/mastering headphone. Superb entry-level high-end can for casual listening, too, with that warm, thick, finely nuanced, and organic Sennheiser house sound. If you want more resolution than HD600 but none of HD650's character, this baby should do it for you. Aside from that, comfort is supreme. The build quality doesn't seem up to par with HD650, though, but still better than most cheaper headphones. Placement of sounds is sharper and clearer than HD650 and HD600, though not by much. This is no K702 and HD800 killer, however. It's high impedance demands you have at least a Schiit stack for best results, or you are better off with cheaper, low-impedance ...

    One of the best options on the market for entry level audiophile headphones.

    My setup consists of these HD600s run to a fiio K3 then to my MacBook Pro streaming from tidal. This setup has served me very well, and the clarity achieved by these headphones is incredible. I’m relatively new to audiophile equipment, but I can truly say these are the best I’ve used so far. If you’re looking for entry level equipment at a reasonable price, these are your best bet.

    My new favorite pair of headphones.

    Impressive and impactful natural bass. Excellent clarity and detailed sound. Broad soundstage. Light weight and comfortable for extended use. I use a small battery operated headphone amp to insure adequate power. It seems to work fine with this setup. Very impressed.

    it is a great headphone. I have Sennheis...

    it is a great headphone. I have Sennheiser HD 600. But this one exceeds 600 in many aspects. the Quality of the sound, of course, is the first and main. You feel as if you can hear every, even the shortest and slightest, of the sound. Absolute satisfaction. But do not forget to amplify these effects with good sound's application

    Amazing headphones

    Amazing headphones, bought a decent dac with it for the mean time and man, I was talking about them for days, and still am they have changed the way I have heard audio in such a long time, also hearing things you never hear is also crazy. Thanks for the amazing headphones.
