Bluetooth audio transmitter BlitzWolf BT05 3.5mm, Bluetooth 5.2

BlitzWolf BT05 is a compact Bluetooth 5.2 transmitter and receiver with a 3.5 mm audio port designed to add wireless audio streaming to devices that lack native Bluetooth. It supports both TX (transmit) and RX (receive) modes, dual pairing for two Bluetooth devices at once, and offers up to 20 hours of playback on a single charge thanks to its 250 mAh battery. Bluetooth 5.2 ensures a stable connection within a typical range of up to 10 meters, and the package includes a 3.5 mm audio cable and USB charging cable for immediate use.

Advantages

The BT05 uses a Bluetooth 5.2 chipset that provides fast, stable transmission and reduced latency. It supports common audio codecs including aptX, AAC and SBC, and the device can automatically reconnect to previously paired devices. Dual pairing lets you connect two headphones or receivers simultaneously, and an integrated microphone permits answering calls directly from the unit. Compact form factor and included accessories simplify setup and compatibility with a wide range of audio sources.

Usage recommendations

For best performance keep the BT05 within 10 meters of connected devices and avoid obstructions between units. Use TX mode for sending audio from legacy sources to Bluetooth headphones and RX mode for receiving audio from a phone or tablet to wired speakers. When using dual pairing, test playback on both receivers to confirm audio synchronization and select aptX-capable headphones if lower latency is required for video or gaming.
