Adapsonic Stereo Bluetooth Adapter Cassette - For Phone Phone Call's and Music Streaming - Supports A2dp
I feel like this is a really good cassette  but when I first got it,  charged it  up it only lasted 40 45 seconds before popping back out of my cassette  player. I think that it might be my cassette players  fault,  I never had any problems connecting it with other devices.
