Dual-Link Bluetooth Transmitter

The Scosche JS17 is a compact Bluetooth transmitter and receiver designed for users who want wireless audio from devices with a 3.5mm AUX output. It supports dual-link pairing so two headphones can listen to the same source simultaneously. The clip-on form factor suits travel, gym sessions, and in-car use.

3.5mm AUX Interface Limits

Connectivity relies on a standard 3.5mm auxiliary port, so the host device must provide an analogue output. There is no digital or optical input, and the unit cannot pair with more than two headphones at once. Battery life varies by mode, delivering 10 hours in transmit mode and 14 hours in receive mode per charge.

Battery Capacity and Headroom

A full USB-C charge takes 2 hours and powers the adapter for up to 14 hours in receiver mode or 10 hours in transmitter mode. That runtime covers most flights, commutes, or workouts without recharging. Extended back-to-back sessions will require a mid-day top-up from a power bank or USB port.
