I HAVE TRIED SEVERAL BLUE TOOTH HEADSETS, AND THIS HAS BEEN BY FAR THE BEST AND MOST COMFORTABLE AND MOST TROUBLE FREE.

• Please tell us about the quality of the product. EXCELLENT
• Was the product free of any manufacturer defects? YES

I bought this headset a week ago to use while I was driving, works great. My wife says that it sounds better than when I'm just using the cell phone so I wear the headset all the time now. I haven't tried it out for distance yet as the phone stays in my shirt pocket. No echo, no tunnel effect, very light and comfortable, couldn't be more pleased!!
