Versatile 2-in-1 Bluetooth 5.3 Adapter

The KAIY C28 adds wireless audio to any device with a 3.5 mm jack. It operates as a transmitter sending TV or airplane sound to headphones, or as a receiver streaming phone music to a car or home stereo. The compact unit weighs 30 g and measures 0.78 in by 0.39 in by 2.34 in.

Ideal for Travelers and Legacy Audio

This suits anyone who wants Bluetooth on older stereos, in-flight entertainment or car aux ports without cables. It is not for users who need aptX HD or LDAC codecs, multi-point pairing, or a digital optical connection. Buyers requiring aptX Adaptive should look at something else.

Built-In Battery and Hands-Free Mic

A rechargeable cell provides up to 4 hours of continuous transmit or receive time. The integrated microphone enables one-touch call answering and relays navigation voice prompts while driving. No extra cables or software are included beyond the 3.5 mm aux interface.
