Have very long to wireless headphones, mainly on the Internet, researched. In the hearing preselection devices from Sennheiser, Sony, AKG and Phillips went around the 150-200 euro. Only the Sennheiser RS180 could sonically satisfy reasonably. But all these devices seemed very sticky for the price. Then I got the MDR HW700DS in the hands and on the ears (and got the feeling no longer bought): lonely peak. Forget all the aforementioned kid stuff when her music course, want very well resolved and listen for hours. Similar sounds good still (similarly high price) of the AKG K 840 KL but the Sony is more steam, due to its larger Abmessungern. Fair to be added that the RS220 Sennheiser did not participate in this competition, which should therefore still be wisely (but again, cheap-looking haptics). Haptics, processing, handling and excellent comfort to luxury hotels MDR HW700 DS. He Eigent itself. For pure stereo sound from the (high quality) CD player just as fabulous as other digital and analog sources HiFi quality: yes certainly. High-end: no, but also not far away from it. Yes, the price is high, but in the long run to make the paid in long joy of fantastic sound. Nevertheless, my tip: make extensive listening tests own.
