Bluetooth 5.3 Transceiver for Car Audio

The LENDAWAY ktbv-374 adds wireless streaming to any device with a 3.5 mm auxiliary input. It operates as a transmitter to send audio from a TV or PC to Bluetooth headphones, or as a receiver to play phone audio through a car speaker system. A simple TX/RX switch toggles between the two modes.

Up to 10 Hours Battery Life with USB Charging

The built-in rechargeable battery supports up to 10 hours of continuous wireless use on a single charge. A Micro USB 2.0 cable provides power and enables PC transmitter mode when connected to a computer. The supplier notes that charging while streaming may introduce ground-loop noise, so fully charging before use is advised.

Replaces Wired Aux Connections for Older Stereos

This adapter upgrades non-Blacketooth car speakers, home stereos, or TVs without requiring new hardware. It is not suited for buyers who need a built-in microphone for hands-free calls, as the specification confirms no microphone is included. The package includes a 3.5 mm audio cable, Micro USB cable, and user manual.

Questions about this item

Does the ktbv-374 get warm or make noise after running for 10 hours on its built-in battery?

The adapter weighs 42 grams and has no moving parts, so it runs silently and stays cool during the full 10-hour battery life.

What cable or port must my TV or stereo already have to use the ktbv-374?

Your device needs a 3.5 mm audio jack; the package includes a 3.5 mm audio cable for that connection.

Will the ktbv-374 pair with a Bluetooth 3 headset I still use?

Yes, Bluetooth 5.3 is backward-compatible, so the ktbv-374 will connect to older Bluetooth 3 headphones or speakers.
