It didn't work out of the box. Was able to pair with headphones but no sound. Connected per instructions. There is also no way to delete previously paired headphones.

The unit connects fine and initially sounds good with almost no delay. But during use the audio becomes choppy for a while then clears up. Minutes later it happens again. This audio problem continually repeats.
