If you want an excellent bluetooth headset for calls this one is terrific. After trying one for my wife I went and bought 4 more for myself and 3 kids. What I love is that it is hard to tell that you are on a bluetooth headset. I have asked everyone I call how it sounds and usually they say "I can't believe it is a bluetooth". I also like the way the mic extends. It picks up your voice easily and it is comfortable. Comes with several sizes of ear plug attachments that makes it easy to find one that fits your ear. I use mine with an LG Versa cell. I have downloaded music and listening on my cell it sounds OK but it is not as good as a wired headset or earphones. With the terrific price on Amazon and free shipping I am extremely happy with this buy.
