## Overview

It supports simultaneous connection of two Bluetooth headphones or AirPods, delivering high-quality, low-latency sound via Qualcomm aptX Adaptive and aptX HD codecs.

Compact and durable, it’s the ultimate travel companion for professionals who demand premium sound and effortless sharing.

## 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: 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: buena - muy buena compra, justo lo que necesitaba.

### ⭐⭐⭐⭐⭐ Bestes Gadget für Langstreckenflüge!
*by B***. on 17 January 2026*

Ich habe mir den Adapter primär für die Nutzung auf Langstreckenflügen zugelegt. Mein Fazit nach 2 Mittel- (> 3 Std.) und 3 Langstreckenflügen (> 8 Std.): Top! Für mich ist es ein Gamechanger, endlich meine Bluetooth-Kopfhörer (JBL Live Pro 2) mit dem Bordentertainment verbinden zu können - um einerseits Filme in besserer Tonqualität genießen zu können, aber auch eventuelle Störgeräusche ausblenden zu können. Folgende Kriterien waren entscheidend dafür, dass ich mich für den Avantree Relay entschieden habe: - lange Akkulaufzeit: wird mit ca. 20 Stunden angegeben. Kombi aus Mittel- und Langstrecke mit in der Summe je 14-18 Stunden hat das Gerät anstandslos mitgemacht! - schnelles Wiederaufladen: wird mit ca. 20 Minuten angegeben. Ich habe keine Stoppuhr gestellt, aber es geht wirklich verdammt schnell, bis das Gerät wieder einsatzberei ist, nachdem der Akku leer war. - Low Latency-Unterstützung: Ich war im Vorfeld etwas skeptisch, da ich immer wieder von Verzögerungen bei der Ton- im Vergleich zur Bildübertragung gelesen habe. Um diese zu vermeiden, müssen sowohl Bluetooth-Adapter als auch Kopfhörer diese Funktion unterstützen. Bei mir hat das mit dem Avantree in der Kombi mit dem JBL Live Pro absolut einwandfrei funktioniert! - Design und Funktionen: ich empfinde es als praktisch, dass man auch am Adapter eine Möglichkeit zur Lautstärkeregulierung hat. Allgemein ist der Adapter nicht nur klein und leicht, sondern wirkt auch wertig verarbeitet und ist intuitiv bedienbar. In blau passt er sogar farblich zu meinen Kopfhörern! Das war zwar kein Kriterium, ist aber trotzdem nett ;-) Der Artikel war gut verpackt und der Lieferumfang umfasst neben dem Adapter selbst auch noch ein Ladekabel und einen Dual-Aux-Adapter, dazu noch ein kleines Täschchen, in dem sich alles für die Reise perfekt verstauen lässt. Von mir eine klare Kaufempfehlung - ich bin wirklich sehr zufrieden.
