Avantree SoundJet R1 Airplane Bluetooth Transmitter — aptX Adaptive, 25H Battery, USB-C (Works with AirPods & Bose)

Avantree SoundJet R1 is a compact airplane Bluetooth transmitter that converts a 3.5mm or dual-prong in-flight audio jack into a wireless aptX Adaptive stream for your AirPods, AirPods Pro, AirPods Max, Bose, and other Bluetooth headphones.

Whether you fly frequently or take the occasional long-haul trip, the SoundJet R1 is engineered to replace tangled cables and incompatible airline jacks with clean wireless listening. It pairs with most Bluetooth headsets and uses a Qualcomm chipset to prioritize stability and improved audio quality, while its long battery life and USB-C charging keep it running through extended flights.

How do I use the SoundJet R1 on an airplane?

Plug the SoundJet R1 into the plane’s single 3.5mm socket or attach the included dual-prong adapter for older seats. Put your Bluetooth headphones into pairing mode and the transmitter will connect, sending audio from the in-flight entertainment system to your headset.

• Includes a dual-prong airplane adapter for legacy airline seats
• 3.5mm plug for modern jacks — simple plug-and-play setup
• Requires headphones to be in pairing mode to establish connection

What audio quality and codecs does the device support?

The R1 uses a Qualcomm Bluetooth chipset with aptX Adaptive and aptX HD support to provide better bitrate handling and lower latency than standard SBC, improving clarity for movies and music on flights. It’s optimized for stable wireless audio transfer in noisy, interference-prone environments like aircraft cabins.

• Qualcomm chipset for consistent wireless performance
• aptX Adaptive and aptX HD support for higher-resolution streaming
• Engineered to reduce dropouts in crowded RF settings such as airplanes

How long will the battery last and how do I keep it charged?

The SoundJet R1 delivers up to 25 hours of continuous playback on a full charge, making it suitable for multi-leg or ultra-long-haul trips. If you need to recharge mid-flight, the unit supports in-use USB-C charging so audio can continue while the battery replenishes.

• Up to 25 hours of runtime on a single charge
• USB-C charging port supports charging during use
• Compact battery design keeps the transmitter small and travel-friendly

Will it work with my AirPods, AirPods Pro, AirPods Max, or Bose headphones?

Yes — the SoundJet R1 is designed particularly to complement AirPods and similar premium headsets, but it is also compatible with most Bluetooth headphones from other brands such as Bose. Note that the transmitter only sends audio to Bluetooth headsets and does not act as a receiver for TVs, phones, or instruments.

• Compatible with AirPods, AirPods Pro, AirPods Max, Bose, and other Bluetooth headsets
• Not intended as a receiver for TVs, phones, or musical instruments
• Headphones must enter pairing mode to connect successfully

Who is this for? Frequent fliers, business travelers, and anyone who prefers wireless over wired in-flight audio will find the Avantree SoundJet R1 useful. It’s tailored for owners of AirPods and other premium Bluetooth headphones who want higher-quality, low-latency audio during travel, plus travelers who need long battery life and the convenience of USB-C charging. If you need a simple, portable way to ditch airline headphone cables and stream airplane audio to modern headsets, the SoundJet R1 is a practical travel accessory.
