Disappointment! As usual staunch devil customer headphones were sent back after 2 days. At the sound could not be faulted, however, the headphones expressed both me and my wife just 5 minutes on top of the head. No wonder, because the strap is made of rubber (without pads) and at weaning, it may happen that it tweaks uncomfortable in your hair. The buttons on the ear feel in my opinion not enough quality. For the price expected a lot more. Positive noticed are me only the packaging (padding) and the coupling via NFC. Property me now the Jabra Revo Wireless bought. These meet all of the above clearly better. After the disappointment with the Heimlich, and now with the headphones it was quite clear the last order of a product of the devil for me.
