This is my fourth or fifth Bluetooth headset. I had one or more of the following three problems with all my previous Bluetooth headsets:1. Poor sound quality: Person on the other end said my voice was very soft or sounded like I was on a bad speakerphone with a loud echo.2. Poor volume: The speaker volume in my ear was too soft for me to hear well even with the volume cranked all the way up.3. Very slow to connect: Took 3-4 seconds to pick up a call and the person on the other end of the line was always saying "Hello, hello?"This Bluetooth headset has NONE of the above listed problems. It is very clear and loud for me and I've yet to have a single person say they couldn't year me well or that they got an echo when talking to me(been using it now for about 5 months). I speak in a normal voice without having to yell into the mic. It also picks up calls very quickly. It beeps three times and I can talk right away, no delay. It is also comfortable, I can wear it for multiple hours without discomfort. I like it so much I'll use it in my car even though my car has the Bluetooth connectivity so I can talk and hear the caller through the speakers. Also, the battery life is great. I went on a fishing trip for 4 days and it worked the whole time without a recharge.The only slight con is that the part that goes around the back of your ear is quite large. It isn't the most visually appealing headset out there. I feel it is a small price to pay for it working how I want it to.Bottom line: Works like you would expect it to and has finally made Bluetooth headsets usable for me.
