Plug-and-play wireless audio adapter

The Scosche C28 adds Bluetooth 5.0 to any device with a 3.5mm aux jack. One button toggles between transmitter and receiver modes without an app or pairing codes. It suits drivers of pre-2015 vehicles, turntable listeners and anyone who wants wireless headphones for a TV or projector. The built-in microphone enables hands-free calls when used in a car.

Dual TX and RX modes over 3.5mm aux

In receiver mode the C28 streams music, navigation and calls from a phone to a car stereo or wired speaker. In transmitter mode it sends audio from a TV, turntable or projector to Bluetooth headphones or a speaker. Both directions use the same 3.5mm connection and pair in seconds. No other interfaces or cables are required.

Up to six hours per charge with LED status

The rechargeable battery runs for six hours and refills in two hours via USB at 5 volts. A red and blue LED shows the remaining level. Stable range reaches 10 metres or 33 feet in open space. Noise cancellation helps keep calls clear. The adapter weighs 0.04 kilograms and measures 60 by 22 by 12 millimetres.

Questions about this item

How does Bluetooth 5.0 range hold up inside a car or living room?

The link stays stable up to 10 metres (33 ft) in open space; walls and seats reduce that, but typical car or room distances remain well within reliable coverage.

What does the 3.5 mm aux connection actually limit for audio quality?

The analogue aux jack caps the signal to stereo line-level output, so quality depends on the source device's DAC and the headphone or speaker amp, not on the Bluetooth codec.

Will the 60 mm height clear the dashboard trim around my aux port?

At 60 mm tall, 22 mm wide and 12 mm deep, the adapter fits most recessed aux sockets; very tight surrounds may need a short 3.5 mm extension cable.
