When processing the headphones I'm a little torn. On the one hand he can see quite cheap from in kind, on the other hand it makes the touch less the impression. Nothing has more game than it should have, the thrusters of size regulation are beautiful cumbersome, so he once set properly not adjusted again.
As for the sound they sound balanced nice for the price. For me personally missing a little the depths, but this is again felt very comfortable from others.
What I personally found very awesome was the range. I could move easily in my 60qqm apartment where my more expensive Bluetooth boxes often have problems.
for 70 really nice headphones with decent range and a balanced sound.
Personally, I too little bass so they go back but the larger REVO Wireless are already ordered.
