[DEAD] Esinkin 2 in 1 Bluetooth Transmitter and Receiver for $20

This lightning offer expired too…

This is a bit of a curiosity, it looks like they put a bluetooth transmitter and a receiver in a shell very similar to that of a …Fiio headphone amp! It is the Esinkin 2 in 1 Bluetooth Transmitter and Receiver going for $20 with free shipping until 9:05am ET as part of the Gold Box daily deals.

It can work as a bluetooth transmitter (TX) or receiver (RX), and has a 3.5mm audio port. I haven’t used one of these, but I don’t think you can use it as both at the same time since it has a switch for the two modes (RX or TX). It has a built-in rechargeable battery and is powered/charged via microUSB. Take that Chromecast 😉 It averages 4.3 out of 5 based on 35 customer reviews.

PS: take the claims of zero latency with a grain of salt as this is bluetooth 🙂
