It was difficult to pair it with my computer at first. Email to technical support went unanswered (still haven't received a reply.)
After I got it set up, it is awesome! The sound is great! I watch a lot of movies on my computer (and sometimes disturb my family) and I hate being attached to a cord, so this is perfect! I had another wireless headphone set and it was absolute junk.
I can't comment yet about the battery. I have had some issues related to my computer (not this device) that kept it from charging properly or charging at all. From what I have seen, it's going to have a long battery life, it has been staying charged all day.
