Bluetooth 5.0 Audio Receiver and Transmitter, 2 in 1 Dual Output USB Adapter for Computer, TV, Car Stereo Description

This portable, lightweight wireless audio transmitter and receiver provides a flexible wireless audio solution for computers, mobile phones, televisions, home speakers, and car speakers. It uses Bluetooth 5.0 technology for fast transmission and stereo audio playback, helping you add wireless audio connection to everyday devices.

Specifications: model KN330; technologies include BT 5.0, A2DP, and AVRCP in receiver mode only. The operating range is up to 10 m / 33 ft without blocking objects, and the pairing name in receiver mode is KN330. TX indicates transmitter mode with the red LED on, while RX indicates receiver mode with the blue LED on. Dimensions: 45 mm x 20 mm x 11 mm.

Mode switching is handled with the TX/RX switch. TX is the transmission mode with a red LED, and RX is the receiver mode with a blue LED. There is no built-in battery, and the unit is powered through a DC 5V USB interface.

When powered on in transmitting mode, the red light stays on, flashes during pairing, and remains on after pairing succeeds. In receiving mode, the blue light is displayed, flashes during pairing, and stays on after pairing is successful. This makes the operating status easy to check during use.

For computer use, no audio cable or driver is required, and the device supports plug-and-play for audio transmission only, not data transmission. For non-computer devices with audio output such as a TV, connect one end of the audio cable to the device's audio output and the other end to the transmitter or receiver, then plug the unit into USB power and set it to TX mode to pair automatically with a Bluetooth headset or Bluetooth speaker. It can also be used with home speakers, wired headphones, and car speakers that do not have Bluetooth, or with a phone through an audio cable connection to the speaker and the unit.
