Your beloved speakers may sound great—but if they’re a bit older, they may be lacking in one department: Bluetooth. With the Xduoo XQ50, that’s about to change. Featuring coaxial outputs and a state-of-the-art CSR8675 Bluetooth receiver with support for the latest formats, the XQ50 can turn any pair of coaxial speakers into Bluetooth-enabled listening solutions. A cutting-edge CS8406 digital-to-audio conversion chip converts Bluetooth signal to high-quality optical/coaxial output, while an ES9018K2M decoding chip delivers analog signals with high S/N and low THD. The XQ50 can also be connected directly to a computer as a USB sound adapter that converts audio into an analog signal output. Simply plug it in, and it’s ready to go.
