Because I make international flights on a regular basis. For travel, noise canceling headphones are a must-have, but most are now bluetooth. Unfortunately, most cattle class seats have infotainment systems that only provide mini-jack outputs. Enter this device as the perfect solution! At least in my opinion. This device allows me to plug-in to the output jack on an aircraft without the inconvenience of wires. It has several domestic uses, specifically provided a bluetooth interface to older audio equipment, PC's that don't have bluetooth, and (some) tablets. Does it work? Yes, no reservations. Fully charged, the battery was only 50% drained at the end of a 10 hour flight to London from Phoenix, AZ. I used this device in conjunction with my iPad mini, the aircraft infotainment system and even my PC at home. Binding was fast and effortless. Recommend you read the instructions because although binding and unbinding is easy (and works) the unit itself has a minimum of controls and you need to know what you're doing! I really can't speak to quality or range, but at least up to around ten to fifteen feet it was working fine, and sound quality was excellent without drop-out or interference. Can I listen to music while the unit is attached to a charger? Yes you can. This was a worry for me, especially since I forgot to recharge before the return trip. So I attached to a USB-C power bank and absolutely no problem, throughout charging, the unit worked fine. BTW, many airlines seem to be banning the use of power banks on or onto their aircraft - just another nuisance to check on before you fly! Do I know how much power is left? Yes, there are 4 white LED's which tell you how much charge you've got on the device. The top-most illuminated LED flashes until the next level is reached or the unit is fully charged. Finally, can two people listen to the same audio? Yes, my wife and I watched a video on the plane, with both of us wearing Bose NC headphones in bluetooth mode. The unit provides two, simultaneous links so for me that was the final box ticked. Some widgets are hard to use, but this one is well thought out and easy. Review: Good value, works well - Worked well, connected easily to my headphones and a second pair of ear pods so my wife and I could both listen to a movie on a flight. The battery life seems as advertised. I was a good value for the cost and the sound was very clear. ## Features - 【Enjoy Wireless Audio on Airplanes】Plug Relay directly into a standard 3.5 mm seatback audio jack or use the included dual-prong airline adapter on compatible aircraft.

Please note that most true wireless earbuds (such as AirPods) do not currently support these audio codecs. **Q: How are the volume levels?** A: You should be able to reach sufficient volume levels by adjusting the volume on both the Relay, your headphones, and / or the audio source. **Q: How long does it take to fully charge the adapter?** A: It only takes 1.5 hours to fully charge the adapter. **Q: Can I connect my phone to the Relay via Bluetooth?** A: No, as a transmitter, the Relay is designed to only connect to audio devices (such as your headphones or AirPods) via Bluetooth. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ideal for flying with bluetooth headphones; a well thought out product *by A***L on November 12, 2025* Why did I buy this product?

The battery life seems as advertised. I was a good value for the cost and the sound was very clear. ### ⭐⭐⭐⭐⭐ Works perfectly for downloaded movies on laptops for long flights *by B***M on January 22, 2026* This relay works great with our laptops! The instructions were concise, clear, and both sets of our ear buds were very easy to pair and use with it. We can now watch our downloaded movies on our flights with each of us having our own set of earbuds instead of having to share one set, lol. We especially appreciated how the instructions boldly point out to turn off our phone Bluetooth during pairing because that causes 90% of problems...sure enough, that instantly worked. We also like the included charging cable, plane adaptor and sturdy zippered carrying case. ## Frequently Bought Together - Avantree Relay - Premium Airplane Bluetooth 5.3 Adapter, Supports 2 AirPods or Headphones with aptX Adaptive, 3.5mm AUX Jack Wireless Audio Transmitter for Planes, Airline, Travel, TV - SARISUN Travel Pillows for Airplanes, Airplane Pillow for Long Flight, Airplane Head Strap with Eye Mask for Sleep, Travel Neck Pillow for Car Road Trip, 360° Support Headrest, Stop Bobblehead, Black - Airplane Pockets Airplane Tray Table Cover with Pocket Organizer | Seat Back Organizer & Storage for Personal Items | Travel Accessories | Clean and Convenient Airplane Travel Essentials for Flying --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/582838981-avantree-relay-airplane-bluetooth-adapter-for-2-airpods-or-headphones](https://www.desertcart.sn/products/582838981-avantree-relay-airplane-bluetooth-adapter-for-2-airpods-or-headphones) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-07-26*
