Review on Sennheiser HD 600 Professional Stereo Headphones - Open Dynamic Design for Hi-Fi Audio (Black) by Ognian Dimitrov ᠌

Headphones are tight 300 Ohm, so they won't work for a phone and some players (besides, the design is open) you need to buy an external amp with a DAC (I took fostex hp-a4bl to them). Its pros: Build quality, sound quality, good interchangeable cable included, interchangeable ear pads and headband foam. Some cons: On the head, the headphones are not the most comfortable, the design of the type like the dt990 sits much more comfortably.
