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 - 【Designed for Airplane Seat Screens】This Bluetooth adapter connects directly to airplane entertainment systems via the standard 3.5mm AUX jack. Say goodbye to company cables and poor quality wired headphones for a cleaner in-flight wireless experience. - 【Connect 2 in-flight headphones】Pair two Bluetooth headphones or AirPods simultaneously and enjoy on-board entertainment together. A smarter wireless upgrade for couples or fellow travelers who want to look side-by-side on the plane. - 【Not suitable for TVs, phones or listening assistance devices】Not compatible with TVs, listening assistance devices or musical instruments. Bluetooth transmitter only - does not match with phones or tablets. - 【Clear and Reliable Travel Audio】Powered by Qualcomm aptX Adaptive technology to deliver balanced sound and reliable wireless performance for the duration of your flight. - 【25 Hours Reliable Playtime】 Up to 25 hours of wireless listening time on a single charge — ideal for long international flights and frequent travelers. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CL9C95T9 | | Additional Features | aptX Low Latency, Supports 2 Headphones | | Audio Input | 3.5mm AUX | | Audio Output Mode | a2dp | | Audio Output Type | Headphone | | Battery Charge Time | 2 Hours | | Battery Type | Lithium-Polymer | | Battery Weight | 4.4 Grams | | Best Sellers Rank | #7,125 in Electronics ( See Top 100 in Electronics ) #200 in Car Audio & Video Accessories | | Bluetooth support? | Yes | | Brand | Avantree | | Built-In Media | Dual 3.5mm Male to 3.5mm Female, Relay, Travel bag., USB Type C Charging Cable (0.5m), travel bag | | Color | White | | Compatibility Options | Headphones, Tablet, Airplane Entertainment System | | Compatible Devices | Headphone, Airline Entertainment System, Gym Equipment | | Connectivity Technology | Bluetooth | | Connectivity technology | Bluetooth | | Connector Type Used on Cable | Auxiliary | | Control Method | Push Button | | Controller Type | Hand control | | Customer Reviews | 4.4 out of 5 stars 1,890 Reviews | | Data Link Protocol | Bluetooth | | Enclosure Material | Acrylonitrile Butadiene Styrene (ABS) | | Hardware Interface | Bluetooth, Bluetooth 5 | | Includes Remote | No | | Installation Type | wireless | | Item Dimensions L x W x H | 16.4L x 1.9W x 14.5H centimeters | | Lithium Battery Weight | 4 Grams | | Lithium-Battery Energy Content | 0.8 Watt Hours | | Manufacturer | Avantree | | Material | Acrylonitrile Butadiene Styrene (ABS) | | Model Name | Relay | | Mounting Type | airplane | | Number of Batteries | 1 Lithium Polymer batteries required. | | Number of Channels | 2 | | Number of Lithium-ion Cells | 1 | | Number of Ports | 2 | | Outer Material | Acrylonitrile butadiene styrene (ABS) | | Power Source | Battery Powered | | Power source | Battery Powered | | Product dimensions | 16.4L x 1.9W x 14.5H centimeters | | Rechargeable Battery Included | Yes | | Special features | aptX Low Latency, Supports 2 Headphones | | Supported Application | Any audio application or format supported by the connected airplane entertainment system | | Supported Media Type | bluetooth | | Supported Standards | Bluetooth, aptX Adaptive | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** Avantree - **Connectivity technology:** Bluetooth - **Material:** Acrylonitrile Butadiene Styrene (ABS) - **Power source:** Battery Powered - **Special features:** aptX Low Latency, Supports 2 Headphones ## Images ![Avantree Relay - Premium Airplane Bluetooth Adapter with Advanced Qualcomm Chipset, 2 Headphones Support, 25hrs Play Time, aptX Adaptive & HD Audio Transmitter for Airpods, Bose & Travel Flight - Image 1](https://m.media-amazon.com/images/I/41+EuzcVwBL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Allzweckgerät *by T***U on 7 December 2025* Der Adapter kam sehr gut verpackt an.
