Conclusion after good 6Monaten

Hi first;)
got it as a Christmas present and was only by great design and sound überweltigt after the erstn two weeks verreckten the first batteries, with strong bass listeners then switch off and on again, very annoying ... Normal batteries will last approximately 5-9 hours but no longer necessary (depends on several factors therefore very imprecise information from me [temp, music, bass ....]) to all diedas ANC krisieren: I agree with him, it would have sold better MONSTER as an amplifier and the mics omitted at wind! EXTREME! constantly annoying noise ...
The sound is the same as still very eindurcksvoll the first bass drum, the white head band is still white but the cable entry, it has become more brown the same is a shame even to the cables ...
processing: after only 3 months, the aluminum parts during headband 0,7-1mm slipped down a gap is created very ugly: S
the ears have become loose (not only the folding mechanissmus but also the anchor with the headband)
but all in all the whole in keeping limits and I use the handset still happy at home, at school and on the go.
