I purchased the Motorola Headset after receiving numrous complaint regarding the sound quality frmo the Jabra BT500 headset I had been using. The noise cancellation is excellent. No longer do I have people complaining that I sound like I am on an airport runway. Everyone speaks highly of the clarity of our conversation. The Motorola H700 is small, lightweight, and paired easily with my telephone. I highly recommend this headset for any user who depends on a mobile telphone. The only minus is the battery life seems to be short. 3 to 4 hours before requiring a recharge. This is probably good for most but I have to "feed" the headset at least once a day. Great headset - you should seriously consider buying one!
