I just got a pair of Monoprice MP15276 headphones, which so far, have been well worth the $30. They pair with my iPhone and Mac just fine. They sound great, no issues, when using with my phone. But on my Mac, I get pretty consistent choppiness, and I don't know what to try next. I have reset the PRAM, SMC, and bluetooth itself, no luck. My Magic Keyboard, and Magic Trackpad 2 both work fine. Any ideas as to what I should do next?
