The Bluetooth Transmitter Receiver is a pocket-sized 2-in-1 wireless audio adapter that works in two directions — send audio out or bring audio in — making it one of the most versatile Bluetooth adapters available for everyday use.

AS A TRANSMITTER (TX MODE): Plug into any 3.5mm AUX jack and stream audio wirelessly to your Bluetooth headphones or earbuds. Use it on airplane seat-back screens to watch movies with your own headphones, on your TV for late-night streaming without disturbing others, on gym treadmills and ellipticals, on your PC, or on a record player to stream vinyl to a wireless speaker. Pair two Bluetooth headphones simultaneously for shared listening.

AS A RECEIVER (RX MODE): Plug into your car stereo AUX port and stream music from your phone wirelessly — the built-in microphone lets you take hands-free calls safely through your car speakers. Also works with old hi-fi systems, bookshelf speakers, and active speakers to give them instant Bluetooth capability. Pair two source devices and switch between them with one button press.

UNIVERSAL COMPATIBILITY: Uses SBC codec — the universal Bluetooth audio standard supported by virtually every headphone, earbud, and speaker, including AirPods, Sony WH/WF series, Bose QuietComfort, Samsung Galaxy Buds, and Jabra. Bluetooth 5.4 for fast, stable pairing. Range up to 10 m (33 ft). 300 mAh battery delivers up to 18 hours of playback and works while charging via USB-C.

PLEASE NOTE: SBC Bluetooth latency (~100-200 ms) makes this adapter ideal for music, TV, video, and casual use — but not suitable for live instrument monitoring or real-time stage performance.
TX/RX Dual-Mode 2-in-1 Bluetooth Adapter: Switch between Transmitter mode to send audio from any 3.5mm source (TV, airplane screen, gym equipment, PC, turntable) to your Bluetooth headphones, or Receiver mode to stream from your phone to a car stereo, speaker, or old hi-fi system. No app. No complicated setup
Connect Two Bluetooth Headphones Simultaneously: In TX mode, pair two headsets or earbuds at once and share audio in real time for couples on a flight, late-night TV, or sharing music. Compatible with AirPods, Sony WH/WF series, Bose QuietComfort, Samsung Galaxy Buds, Jabra, Beats, and any Bluetooth 4.0+ device
Universal Compatibility with Smooth Audio Playback: Uses SBC codec, the universally supported Bluetooth audio standard, compatible with virtually every headphone, earbud, and speaker on the market. Audio quality is excellent for music, TV, and video. Note: SBC latency means this is not suitable for live instrument monitoring or competitive gaming
Built-in Mic for Hands-Free Calls in Car and RX Mode: In RX mode, plug into your car AUX port, pair your phone, and take calls safely through your car speakers without touching your phone. Doubles as a Bluetooth music receiver. Range up to 10 m (33 ft). Bluetooth 5.4 for fast, stable pairing
18-Hour Battery with Charging Capability and Dual Source Switching: 300 mAh rechargeable battery lasts up to 18 hours. Charges via USB-C and keeps running while plugged in, never interrupted mid-flight. In RX mode, pair two Bluetooth devices (e.g. two phones) and toggle between them with one button press
