KAIY Bluetooth 5.3 Transmitter Receiver LCD Screen AUXKey Features

• INSTANT WIRELESS FREEDOM: TX Mode turns any non-Bluetooth device (airplane seat jack, TV, PC, CD player) into a wireless audio source. Pair your AirPods, Sony, or Bose headphones via 3.5mm AUX and enjoy true wireless listening. RX Mode receives wireless audio from your smartphone or tablet and sends it to your car stereo, home speakers, or older sound system — instantly upgrading any wired setup to wireless.
• BLUETOOTH 5.3 LOW LATENCY: Advanced Bluetooth 5.3 with low-latency transmission keeps audio precisely synced with video — no noticeable lag whether you're watching in-flight entertainment, binge-watching TV in bed without disturbing your partner, or playing games. Stable 33ft wireless range with zero signal dropouts.
• LCD SCREEN SEE EXACTLY: Blind pairing frustration is over. The built-in visual LCDs available Bluetooth devices in real time — just select your headphones on screen and pairing completes in seconds. Works with 99% of Bluetooth audio devices, including all AirPods generations (Pro, Pro 2, 4th Gen), AirPods Max, Sony WH-1000XM series, Bose 700, and virtually any wireless headphones. No driver installation needed — plug in and play.
• 13H BATTERY + CHARGE WHILE USING: With 13 hours of continuous streaming on a single charge and USB-C pass-through charging (use it while plugged in — zero buzzing or static interference), you're covered for the longest international flights. The rechargeable battery retains charge even after months in your travel bag, so you'll never arrive at the gate with a dead device. Compact at just 0.8oz — lives permanently in your backpack.
• WORKS EVERYWHERE YOUR AUDIO ALREADY IS: Universal 3.5mm AUX compatibility means this single adapter handles every wired audio situation you have: airplane seat jacks (works with standard 3.5mm jacks; dual-prong adapter available separately for older aircraft), car stereo aux-in for wireless Spotify streaming, home stereo systems, gym treadmill jacks, bedside TVs. Seamless auto-reconnect remembers your paired headphones — no re-pairing between sessions. Compatible with AirPods, Sony, Bose, Sennheiser, and all Bluetooth headphones.
