Plantronics - 320 Bluetooth Headset Review

I bought 2 of this model on line about 2 years ago.  I did have to send both back for warr service but other than that they have been great.  Due my husband breaking his I have tried to replace them with the stereo 855 model.   And when he didn't like the preformance on those we tried a Jawbone.  Both were such a disapointment that he repaired his 320 for a third time and is still using it even with the ear piece missing.  I must say I was disapointed in the performance of the 855's (I'm not to happy with Amazon where I bought them as well) and the Jawbone as well.
