## Description

Avantree Relay is a Bluetooth audio transmitter for airplane entertainment systems, gym equipment, and other 3.5 mm audio sources. Connect one or two pairs of Bluetooth headphones or earbuds, control volume on the device, and listen for up to 25 hours. Qualcomm aptX Adaptive and aptX HD are supported with compatible headphones. Relay transmits audio only; it has no microphone and is not designed for phone calls, TVs, hearing aids, musical instruments, or Bluetooth audio receiving.

Review: Allzweckgerät - Der Adapter kam sehr gut verpackt an. Die Einrichtung und die Verbindung mit den Kopfhörern ging sehr fix. Zudem ist die Anleitung auch verständlich. Im Flugzeug konnten wir den Adapter testen. Ergebnis einfach sehr gut. Akku hält lange, Übertragung ohne Verzögerung und in guter Qualität. Das verbinden weiterer Kopfhörer auch einfach. Zudem kann man zwei Kopfhörer sogar gleichzeitig nutzen. Für den Preis super. Vor allem kann man es ja auch außerhalb vom Flugzeug nutzen. Definitiv klare Kaufempfehlung
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.

## Features

- SHARE IN-FLIGHT AUDIO — Connect two pairs of Bluetooth headphones or earbuds to one airplane entertainment screen, so you and a travel partner can listen together without wires.
- CLEAR, RELIABLE WIRELESS SOUND — Qualcomm audio technology with aptX Adaptive and aptX HD support delivers stable, detailed audio with compatible headphones.
- 25-HOUR BATTERY FOR LONG TRIPS — Built for long-haul flights with up to 25 hours of playtime, onboard volume controls, and a clear battery indicator.
- SIMPLE 3-STEP PAIRING — Plug Relay into the 3.5 mm audio jack, put your headphones in pairing mode, and connect. Includes a dual-prong airplane adapter.
- TRANSMITTER ONLY—CHECK BEFORE BUYING — Designed to send audio from 3.5 mm sources to Bluetooth headphones. It has no microphone and is not intended for phone calls, TVs, hearing aids, musical instruments, or receiving audio.

## Questions & Answers

**Q: Will this work with a regular TV?**
A: As long as your TV has an AUX audio output jack, the Relay will work with it.

**Q: Will I get audio lag or lip-sync delays with my headphones?**
A: Your headphones must support either aptX Low Latency or aptX Adaptive in order to eliminate audio latency. 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.
