Bluetooth 5.0 Audio Adapter

The C28 is a Bluetooth 5.0 transmitter and receiver in one compact unit. It adds wireless audio to devices that only have a 3.5 mm jack. The adapter suits users who want to stream music from a computer, TV or projector to a speaker or headset, or who need hands-free calls in a car. It runs on an internal battery and charges in one hour.

Compatibility Check

Verify that your source device has a 3.5 mm output for transmitting mode or that your speaker or headset has a 3.5 mm input for receiving mode. The package includes one 3.5 mm audio plug and a charging cable. Ensure you have a USB power source for the one-hour charge. The working range is 10 metres without obstacles.

Upgrade From Wired Audio

This adapter replaces a fixed 3.5 mm cable between a source and a listener. The jump is worth it when you want to move around within 10 metres or avoid cable clutter in a car or at a desk. It does not add Bluetooth to devices that lack a 3.5 mm port, and it does not support multi-point pairing or aptX codecs.
