Advanced carpel tunnel syndrome makes holding a phone for more than 5 minutes painful.  I've tried various earphones but never liked them.  This headset is perfect!  People I'm talking to can't tell I'm using it, the sound is quiet and clear.  Very lightweight and comfortable, phone can go in my pocket and I can do anything I need to do while talking. Still can't believe the price. 

Question: How was the sound quality?
Answer: the sound is quiet and clear
