The Ring Collar Headset is rated for 10 hours of use which it often times lasted longer in my testing. The headset gets plenty loud and I had no problems when talking to people with the headset. As far as sound quality the headset favors the lower range but is otherwise fairly flat. My only real complaint with the headset is that the magnets and/or location of them does not work very well. When the ear buds were on the ends of the collar I constantly found myself knocking them off or them simply falling off. This is a shame because it is otherwise a great headset.
