With a robust 25-hour battery life and firmware upgradeability, it’s the ultimate travel companion for professionals who demand premium wireless audio on the go. ## Description Stream audio from in-flight or gym to your Bluetooth headphones with this stable, high-quality adapter. Compatible with AirPods, Sony, Bose, and more. Review: Excellent Bluetooth adapter for flights and travel - I picked up the Avantree Relay mainly for use on flights, and it’s been very reliable so far. Setup is simple and quick, pairing easily with my Bluetooth headphones. Once connected, the audio has been stable with no noticeable dropouts or lag, even during long flights. Sound quality is very good for a Bluetooth adapter, and it works well for movies, TV shows, and general audio without sync issues. The adapter itself is compact and lightweight, making it easy to carry in hand luggage or a pocket. Battery life has been more than sufficient for long journeys, and I’ve been able to use it across multiple flights without needing to recharge in between. Build quality feels solid, and the physical controls are easy to use without needing to look at the device. It also works well beyond flights — I’ve used it with gym equipment and other non‑Bluetooth audio sources with consistent results. Overall, this is a well‑designed, dependable Bluetooth adapter that does exactly what it’s meant to do. A great option if you want wireless headphones to work properly with airplane entertainment systems or other wired audio sources. Review: Worked Flawlessly on Two Virgin Atlantic Flights - I bought the Avantree Relay for a return flight with Virgin Atlantic and used it with my Sony WH CH520 wireless Bluetooth headphones. It worked brilliantly on both flights. On the outbound flight, the aircraft had Bluetooth connectivity, but it kept disconnecting, which became really frustrating. As soon as I plugged in the Avantree Relay, my headphones stayed connected for the entire 11 hour flight without a single issue. On the return flight, I was on an older aircraft that did not have Bluetooth at all, so the Relay was essential. The airline does provide wired headphones, but the sound quality is not great, and I much prefer using my own headphones as they block out more background noise and are far more comfortable. I only charged the Relay before each flight, and the battery easily lasted the entire journey with plenty of power to spare. It was simple to set up, reliable throughout both flights, and made a huge difference to my in flight entertainment. I would definitely recommend it to anyone who wants to use their own wireless headphones when flying. ## 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. This Bluetooth transmitter for airplane entertainment streams in-flight movies and music wirelessly to AirPods, Bose, Sony, and other Bluetooth headphones. - 【Clear, Stable Qualcomm Audio】 Powered by a Qualcomm chipset with aptX Adaptive and aptX HD support for clear, stable wireless sound while flying, working out, or traveling. aptX features require compatible headphones; AirPods use their standard Bluetooth codec. - 【25-Hour Battery with Easy Controls】 Enjoy up to 25 hours of playtime with built-in volume buttons and a clear battery indicator—ideal for long flights, workouts, and frequent travel. - 【Not For TVs, Phones, Or Assistive Listening Devices】 Not compatible with TVs, assistive listening devices, musical instruments, or real-time monitoring.

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 ### ⭐⭐⭐⭐⭐ Excellent Bluetooth adapter for flights and travel *by B***D on 15 April 2026* I picked up the Avantree Relay mainly for use on flights, and it’s been very reliable so far.

I guess I now have a new device that I will take a lot of care to avoid stressing the metal of the audio jack on! The tech was working great on a couple of flights until yesterday when I was using it an air steward lightly knocked the device while putting down my in flight meal tray. The audio jack shattered leaving small pieces of metal in the jack socket, my meal and scattered across the cabin floor. So no in flight films and no inflight meal for the last 10 hours of my flight as a result... ## 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.tn/products/585534170-avantree-relay-airplane-bluetooth-adapter-for-2-airpods-or-headphones](https://www.desertcart.tn/products/585534170-avantree-relay-airplane-bluetooth-adapter-for-2-airpods-or-headphones) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-06*
