This is the best Bluetooth earphone I've found for the price. It rests nicely on the ear and it pairs easily to my Nokia phone. All controls are user logical and the audibilty is great not only to me but also to person on the other end. Battery stays charged fairly well and it takes a lot of activity.Only negative features I would note is that the charger is a special stubby configuration and is expensive to replace.I am on my second one as I suspect that persperation did my first one in.I have given one as a gift to a family member who practices medicine and he reports it as being constantly attached to his ear. I would recommend this device to anyone looking for the convenience and SAFETY of having a wireless earphone. If you must use your car as a phonebooth then this the only way to go!
