Well, there's been nothing to complain about ;-) Although no apt-X codec is present, the sound quality is very good, in blind comparison almost no difference to the wired transmission in pop and rock music, with strings is a little difference listen to, but the MP3 codec can do even more to ruin ... The transmission is stable and the range by walls still amazingly good. The pairing WITH THE easy Handyist. Who the NFC feature is missing, it may indeed be retrofitted by a small sticker ;-) In short, am very satisfied!
