2-in-1 Bluetooth Adapter for Car and TV

The Scosche JS13 adds wireless audio to any device with a 3.5mm jack. It works as a transmitter for TV or airplane screens and as a receiver for older car stereos or wired speakers. A built-in microphone enables hands-free calls while driving. The compact dongle suits travellers and commuters who want cable-free listening.

3.5mm Aux Limits TX to 12h RX to 16h

Audio passes through a standard 3.5mm auxiliary connection, so sound quality depends on the source device and headphone circuitry. The adapter charges in about 2 hours via USB-C and delivers up to 16 hours in receiver mode or 12 hours in transmitter mode. Battery life varies with volume level and signal conditions.

Slide Switch Pairing Screen Shows Status

Slide the mode switch to TX or RX, then put the target device into pairing mode. The integrated display shows the active mode, volume level and exact battery percentage. If the wrong device connects, double-click the multi-function button to restart the search. No app or driver installation is required.

Questions about this item

Should I pick the 16 hour RX mode or the 12 hour TX mode for my use?

Choose RX mode for up to 16 hours when adding Bluetooth to a car stereo or wired speaker. Choose TX mode for up to 12 hours when sending TV or airplane audio to Bluetooth headphones.

What does the 3.5mm jack actually do once the JS13 is plugged in?

The 3.5mm auxiliary cable carries stereo audio. In RX mode it receives music from a phone. In TX mode it transmits audio from a TV or airplane seat to paired headphones.

Does the USB-C port limit charging speed or data transfer in any way?

The USB-C cable recharges the internal battery in about 2 hours at 5 volts. The port is for power only and does not carry audio or data.
