I researched this bluetooth headset and found that it worked extraordinarily well with my Motorola V557 cell phone and it had good volume, call clarity and was comfortable to wear. Unfortunately, it was sent by Amazon in a small ziplock bag that was inside a larger ziplock bag containing the charger. The bluetooth headset, which was completely unprotected, must have continually "banged" against the charger during shipping. By the time I got it, the headset was scratched and looked used...like something I had found on the sidewalk. Also, when I shook the headset, something inside rattled. I returned the headset to Amazon for a refund and then bought the same model from a local discount store for 20% more.This was the first time that I have had to return anything to Amazon...too bad that Amazon did not "bubble wrap" the headset itself to protect it during shipping.
