Bluetooth headsets, what multitude of sorts! We have only spoiled for choice: small, large, one ear, two (no more), closed helmet, open and so on :) Here a brilliant concept: a flexible cord and flat that can become tangled, held around the neck and: will not get lost or hinder. Pure happiness! Ultra easy pairing, the smartphone recognizes immediately and very quickly, very simple manipulations make that one takes advantage on. And what a sound! Stereo of rare quality for listening to music is superb, active basses, sharp magnified. The tips may choose from the provided kit, of course charger also. One evening, it was pouring rain and I was afraid to drown the device: Well no, watertight (I can not not say the same for my shoes ...) The sound of conversations is just beautiful, it's like being in the same room with his companion! Turn on or off gets along very well. Simplissime call acceptance, rejection also easy hook. A super talented in the jungle which denotes beautifully. I do not go out without it! A small investment for many effects. I recommend it without hesitation,
