Travel Audio Companion

The KAIY BT13 is a pocket-sized Bluetooth 5.3 transmitter and receiver built for travellers and home listeners who want wireless freedom. It plugs into any 3.5 mm or RCA audio output on an airplane seat, television or game console and streams audio to your own Bluetooth headphones. In receiver mode it upgrades a wired car stereo or speaker system so you can play music or take calls from a phone.

Dual-Mode Connectivity

A single switch toggles between transmitter and receiver roles, while a 3.5 mm jack and included RCA adapter cover the most common audio ports. The unit weighs roughly one ounce and measures 1.1 by 0.55 by 3.9 inches, so it slips into a pocket or bag without adding bulk. A built-in microphone with noise reduction handles hands-free calls in the car or at a desk.

Battery and Range

The lithium-ion cell delivers up to 11 hours in transmitter mode and 14 hours in receiver mode, then recharges fully in two hours via USB-C. Bluetooth 5.3 provides a stable link up to 33 feet with low latency for lip-sync accuracy. The adapter draws minimal power during use, staying cool during long flights or movie sessions.
