I bought this set because the bluetooth remote control my headphones were only compatible with my iPhone. As I bought a Xperia Z and Galaxy S4 I had no remote (especially convenient to adjust the volume). This kit is very convenient, as it works by bluetooth but also nfc, simply place the box in the back of the phone and the connection is alone. The jack port allows you to connect any headphones. There is no loss of quality. I even enjoy to use it to connect to my computer. Whether on mac or PC, if the computer has bluetooth, it is possible to make its wireless headset. Notebook users in particular you'll enjoy this kit. Autonomy is from 6am to see a little more and it is super light. The supplied headphones are correct quality
