This compact 33g device features advanced dual-channel technology, allowing you to stream wireless audio from a single 3.5mm AUX source to two pairs of Bluetooth headphones or speakers simultaneously making it the ultimate adapter for movies, gaming, travel, and in-car use.

The Astrum BT300 Dual-Channel Bluetooth 5.3 Transceiver is a versatile, pocket-sized wireless audio hub designed to bring multi-device connectivity to your home entertainment, vehicle, or travel layout. Equipped with a standard 3.5mm AUX interface, this standalone hardware unit operates seamlessly in both Transmitter (TX) and Receiver (RX) modes, upgrading your legacy televisions, wired soundbars, and older car dashboards into fully Bluetooth-enabled audio systems without requiring applications or drivers.

Standout engineering allows the BT300 to support native dual-channel audio sharing. In transmit mode, you can link two independent pairs of Bluetooth headphones or wireless earbuds to the exact same audio source simultaneously, letting two people watch movies, play video games, or listen to music together without waking the household. In receiver mode, it acts as a flexible bridge, allowing you to swap audio playback controls smoothly between two connected smartphones or tablets on a single home stereo or car auxiliary port.

Built on an advanced Bluetooth 5.3 architecture, the adapter guarantees rapid peripheral pairing, lower latency performance, and a stable, obstacle-free connection range up to 10 meters. The internal 150mAh rechargeable battery fully juices up via an earthed USB-C input in approximately 2 hours to provide dependable, wide-spectrum audio reproduction across a crisp 20Hz to 20kHz frequency response profile. Its ultra-portable 45mm square chassis ensures effortless carrying between your home office, vehicle glove box, or travel luggage.
