iSunnao Bluetooth Receiver - Bluetooth 4.2 Car Kit

I’m still using mine with a pair of Skullcandies for over a year now and the battery life is around 5ish hours of constant music around 80% volume. You really can’t go wrong with these at this price.

The screws that hold the penclip on wiggled loose once, so I took them out and dabbed a little clear nail polish on them before screwing them back in.
