I have owned several of these head sets over the years. I really like the head set. I constantly have problems with these head sets charging. When the USB port gets some wear, charging them can become very difficult. Love the head set! Hate the charging
I prefer to wear the behind head attachment for comfort but am using the standard over head because it folds up better for storage in my car. If the behind the head would rotate and fold like the other style a 5 star for sure. The sound quality is very good.
It turns out its not really what i needed. Its too bulky and bc i move alot at work, the microphone part sways loosely. It will not read caller ID, instead it insists on saying the entire phone number thats calling. Having the ear piece over my ear makes my ear ache. That probably will not happen to anyone using it though.
