When weight training I have always been annoyed that the cable strap headphones. The previous BT headphones were in either test or bad for my purposes (sports) too expensive. When unpacking the P614 BT has to keep the feeling something valent in hand. Then quickly coupled to the mobile phone (no problem) and a bearish sound on the ears had (Metal - loud :-)). Sure, the thing is new and not yet been in long-term test - but the first impression and the first hearing were really good. If everything stays so I would buy the part again.
