Scosche J33 Bluetooth 5.3 adapter

The Scosche J33 is a portable Bluetooth 5.3 receiver that adds wireless audio to any device with a 3.5 mm aux input. It pairs with smartphones, tablets or laptops and includes a built-in microphone for hands-free calls. The compact black unit weighs just 0.5 ounces and measures 1.6 by 1.6 by .4 inches.

Ideal for drivers with older car stereos

This adapter suits anyone who wants Bluetooth music streaming and call handling in a vehicle or home system that lacks native wireless support. It also works with wired headphones or powered speakers that have a 3.5 mm jack. Buyers whose audio equipment has no aux input or who need aptX HD or LDAC codec support should look at other solutions.

Bluetooth 5.3 with dual-device pairing

The single specification that decides fit is Bluetooth 5.3 with simultaneous connection to two source devices. This lets a phone handle navigation while a second device streams music without manual re-pairing. Range reaches 33 ft line-of-sight and the internal battery delivers up to 16 hours of playback per charge.
