Attempting to unpack, charged via USB on PC, Smartphone Bluetooth enabled and schwupps- the device has detected immediately. Because I feel in ear headphones with my little ears uncomfortable, I like this device exceptionally well. It sits well on the ears and the music is transferred 1a. I also think that I can directly regulate the volume and choice of music on the headphones without having to run to the smartphone. This is very pleasant especially in the gym. And the price-performance ratio also agrees.
