This helpful little device will allow you to turn any of your older speaker systems or wired headphones into Bluetooth streamers. It can receive audio wirelessly from any of your Bluetooth-enabled devices and send it over typical 3.5mm or RCA jacks. The TT-BR02 has Blueooth 4.0 with a 32 foot range, gets 10 hours on a single charge (can charge while in use) and can pair two devices simultaneously.
It is the best selling headphone adapter on Amazon and has received a 4.3/5 star rating from over 50 customers. If you would rather just get wireless speakers instead, be sure to check out the new limited edition solid color PLAY:1s.
