The HD 600 from Sennheiser is already pretty long on the market. From this we can perhaps infer his qualities. Previously I had a HD 650, but - for whatever reason - too dull sound. The HD 600 does a lot right, and I would say the one of the neutral coordinated headphones. The comfort is excellent. Sonically, it looks like that the centers are reproduced very clean and wide and affect the heights never pointed or flashy. However, a star I pull off, because the bass is likely to have a little more pressure, because the processing is not exactly sensational (plastic), because the cable is not very long-lived (that of the HD 650 is better and also adjusts the HD 600) and the sound permanently conveys a sense of boredom. The latter, of course falls on if one the HD600 can even compare with other headphones in this price range. Ultimately, this is also a matter of their own Hörgeschmacks. Considered on their own the Sennheiser HD600 is sound pretty good.
