JIMTAB B2 Bluetooth 5.0 Adapter

The JIMTAB B2 is a compact USB Bluetooth 5.0 adapter that functions as both a transmitter and a receiver. It adds wireless audio capability to TVs, home stereos, car audio systems, PCs and projectors. The 2-in-1 design lets you stream audio from a source device to Bluetooth headphones or speakers, or receive audio from a phone or tablet to wired speakers.

Dual 3.5 mm ports and Bluetooth 5.0 range

Two separate 3.5 mm audio ports keep the transmitter input and receiver output electrically isolated for more stable operation. The adapter supports a maximum transfer rate of 3 Mbps and a transmission distance up to 10 m or 33 ft in open space, though physical obstructions and wireless interference can reduce the effective range. It offers improved speed and distance over Bluetooth 4.0.

Check power source and audio connections

The adapter draws power from any standard USB-A port, so confirm your TV, PC, car stereo or projector provides an available port. You will need a 3.5 mm audio cable for each device you wish to connect in transmitter or receiver mode. One button switches between TX and RX modes, indicated by a blue or red flashing LED respectively.
