I was skeptical, I could not see no use ... I finally bought a to easily communicate between two vehicles during a trip and .... well I can do without it !!! The phone connected to the charger, or pocket and you can chat while strolling with 2 hands really free and without semmĂȘler in son !!! So in the end, I use it everywhere and all the time, as long as my appeal must exceed 5 minutes !!! The sound is excellent, provided that the caller speaks well into the phone of course ...
Only problem! there would apparently a sizzling when I put the headset during a call. It should hang up and call for a return to normal ... a shame
