Summary: This is the best blue tooth I have ever used. Most of the blue tooth I have used in the past hurt my ears after about an hour of wear but this one is very comfortable after hours of wear. It is very clear with no static. I highly recommend the Sound ID 510. I don't have any con to tell you about.
Summary: I have had 5 different headsets for 3 different phones and this is, without a doubt the best headset. I have used it with 3 different phones and have had no problems. Great sound quality, easy pairing, easy use and a very compact design. What else could you want?
