Was looking at these ,jabra halo,and jaybird sportsband. I read all the reviews and chose these because of the comfort,fit,and sound. I must say I was extremely pleased with all the above. Works great with my iPhone4. Listen to music plus all my apps. Range is decent. Phone calls come in clear also. For the price and no cord to deal with excellent product. Only thing is you need the iPhone adapter plug to charge if not it has to charge in a computer. If you don't have one you can purchase this cheap on other web sites. Three friends at work purchased these after seeing them at work. If u purchase these u won't be disappointed!
