Made for AirPods and Air Travel

The SoundJet R1 is a Bluetooth transmitter built specifically for airline seat entertainment systems. It plugs into the 3.5 mm headphone jack and includes a dual-prong adapter so it fits almost every aircraft. The compact unit pairs with any Bluetooth headphones, including AirPods, and comes in several colours that match the AirPods line.

Dual Headphone Support and aptX Audio

A single transmitter can connect two pairs of headphones at once, letting two passengers share the same movie or music stream. The Qualcomm chipset enables aptX Adaptive and aptX HD for high-resolution, low-latency audio that keeps sound in sync with the screen. The device only transmits audio; it cannot receive signals or work with TVs, phones or musical instruments.

25 Hour Battery With USB-C Pass-Through

The internal battery delivers up to 25 hours of continuous playback, enough for the longest international flights. A USB-C port allows charging while the adapter is in use so the entertainment never pauses. Physical volume buttons on the side give quick level adjustments independent of the headphone controls. The transmitter measures 5.71 in by .59 in by 6.5 in and weighs very little for carry-on convenience.
