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

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.

Best Connectivity
I had its rival products and was disappointed with intermittent drop in connectivity. Avantree Relay is better. Setting up is very easy. I used it to pair with my Sonos headphones for my 13 hours flight without a single disconnect. Very impressive. I got one each for my family members.
