## Description

Product Description

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: No problem with connection. Works as advertised - Bought it for a recent long airplane ride from Dubai to Canada. Was Flying on ITA Airways. Didn't need to use because ITA allows direct bluetooth connection, but I tested it on my laptop and it worked as stated. Only problem is trying to remember the directions to connect/pair since I don't use it very often.

## 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.
