Summary: sound quality is reasonable. I always find an issue with the ear clips as they break after a few months. They are not easily available outside. once it is broken, it keeps falling off my ear as ear gels don't fit me perfectly. So I am not able to use them comfortably after six months.
Summary: I've been using this product for about a year. It works really well, but I must say it has absolutely the sorriest ear hook I have ever run across. They always break where the ear hook fastens to the Bluetooth devise. I have had to replace the ear hook five times in the time I have had it.
Summary: I am using it for last 5 months. I'm very much satisfied with the long battery life. Generally I use to talk continuosly. The battery lasts for 10hrs. Really it is very efficient product from Samsung.
