Pros: Detailed and natural sound, flat frequency response, glorious mids, nice-looking, somewhat comfortable
Cons: Need time to soften up
These are one of the best headphones I have ever heard, and I have heard a couple. I undoubtedly prefer them to Senn HD650, like them slightly more than Senn HD600 and Beyer DT880. Why? Because they have more natural sounding midrange and airier soundstage, characteristics that fit the music genres I prefer (classical and jazz). In terms of neutrality these are as good as Senn HD800. The bass is nicely extended and precise. Mind you, they need proper amplification. Don't expect them to sound great right out of an iPod. I have heard mine with MF x-can v3 and there is no synergy between the two. A better match is the cheap Pro-ject headphone amp. They sound even better if you drive them with a more powerful amp (ie Burson). I have mine coupled with a Matrix M-Stage V2 and the combination sounds really magnificent. All in all these are one of the best sounding headphones around, and one of the absolutely best values out there today.
