Haiaveng 2 in 1 Bluetooth Transmitter Receiver, Dual Link Zero Lag 11H

• WORKS WITH YOUR OWN HEADPHONES IN THE AIR: Say goodbye to crappy wired airline headphones for good. Plug this Bluetooth transmitter directly into any airplane seatback's 3.5mm headphone jack and stream wirelessly to your AirPods, Bose QC/700, Sony WH-1000XM, or Sennheiser - no wires, no tangled cords, no fighting the seat pocket. The 11-hour battery easily covers long-haul and cross-country flights, and it charges via USB-C while you listen, so you never run out mid-ocean.
• SHARE AUDIO WITH YOUR TRAVEL PARTNER: Both connect your own wireless headphones simultaneously via Dual Link technology - each person controls their own volume independently. Perfect for couples on long flights, parents watching kids' shows, or late-night TV binge-watching without disturbing your partner. Connects 2 Bluetooth headphones at once with fully synchronized, crystal-clear audio.
• ZERO AUDIO LAG FOR MOVIES: The most-asked question about Bluetooth transmitters: "Will the audio match the video?" With this adapter, yes. Low latency technology keeps audio perfectly synced when watching movies on airplane IFE, TV at home, PS5/Nintendo Switch, or PC - no half-second delays that drive you crazy. Bluetooth 5.4 delivers stronger anti-interference and faster pairing than older 5.0/5.2 versions, with a stable 33ft range even through cabin walls and crowded gyms.
• ONE ADAPTER FOR EVERY WIRED AUDIO SITUATION IN YOUR LIFE: TX (Transmitter) Mode: Plugs into any 3.5mm jack - airplane seats, TVs, gym treadmills, PCs, Nintendo Switch, PS5 - and streams to your Bluetooth headphones wirelessly. RX (Receiver) Mode: Plugs into your car aux-in, old home stereo, vintage amplifier, or wired speakers to receive Bluetooth audio from your phone. Stream Spotify through your car or classic home stereo system without buying new equipment. One device replaces a drawer full of adapters.
• HANDS-FREE CAR KIT: The built-in microphone with CVC 8.0 noise cancellation delivers crisp, clear calls even at highway speeds. Answer calls, skip tracks, and control volume directly from the adapter without touching your phone. Works as a plug-in wireless solution for older cars with an aux-in that don't have built-in Bluetooth.
• EXPERT TIP: 99% of pairing issues occur because your headphones aren't in pairing mode. If you run into trouble, quickly Google your headphone model + "pairing mode" for step-by-step guides.
