The first set I bought lasted about 2 weeks before the microphone went out, the replacement lasted 4 days before the microphone went out. Also they were very uncomfortable, made my ears hurt and were ill fitted for small ears.<br />Overall a huge disapointment, my first one with plantronics products. I definete \"DO NOT BUY\"
Output:
Negative Review
