The sound of the headphones is not too shabby either, giving the songs unadulterated again; telephoning is hassle-free.
A point deduction, there was of me because the Bluetooth did not keep the reach of the promises (given 10 m). When I phone (a Huawei Y530 or one amsung S3 mini) have lying in the living room and my go to the kitchen (which are 3 meters) you get noise or interference on the telephone.
This is a bit annoying because my cheap headphones AEG only 8 m have indicated range and the loose hammer out this route without interference.
When one of these small defect does not bother these are the perfect headphones
