Finally a headset, with which I can hear both the stereo and the phone in very good quality music and my surroundings unnecessarily Sonicate. I find the AKG K550 sound very clear and neutral. A large drum may also already the eardrum tickle (eg by Ben Howard "Depth Over Distance"), but without neglecting the heights (eg, the chimes of Emeli Sandé's "Mountains" Live at the Royal Albert Hall). In addition, it should be mentioned that it is very comfortable to wear - even for eyeglass wearers. I want him simply do not want to miss!
