I've used these headphones for 2 years now, they are comfortable, good-looking and, more important than all, they DO sound really good. They helped me make better home studio mixes through revealing some frequencies that usually remained hidden with "usual" (non-professionnal) headphones or speakers. The impedance is very high (600 ohms) compared with most other headphones, so with the same settings the general volume will be lower on these ones than on most other headphones. They also tend to saturate early in the lower part of the sound spectrum (DeeJays, stay away!
), which may help if you have a tendency to overload your mixes with low frequencies. Listening to (and rediscovering) some old records with them can be a real pleasure too...
It is a pity this model is no longer available (it was replaced by the K 240 Studio
which has a lower impedance seems to favor low frequencies and thus shall be less trustworthy for mixing purpose).
