This multi-port Bluetooth 5.0 audio receiver box is an affordable upgrade for all your wired audio equipment. It turns ordinary wired speakers, home amplifiers and car audio systems into Bluetooth wireless audio players in seconds.

Adopted mature Bluetooth 5.0 transmission module, it maintains smooth, lag-free audio transmission with less signal drop even through slight obstacles. The embedded microphone enables clear hands-free calling, great for daily commuting and home meetings.

Rich interface design meets multiple usage needs: RCA red/white ports connect old stereo equipment, 3.5mm AUX jack works with most sound devices, and the USB slot lets you directly play audio files stored on flash drives without Bluetooth connection.

Small lightweight body takes minimal desk space, easy to place beside speakers or car dashboard. It automatically memorizes paired devices and reconnects once powered on, no repeated pairing steps required. Ideal for home audio, car use, desktop speakers and outdoor sound systems.

Upgraded Bluetooth 5.0 chip delivers fast pairing, long transmission range and anti-interference stable wireless audio streaming for daily music playback and calls.

Built-in high-sensitivity microphone supports hands-free voice calls, perfect for car audio systems and home speaker setups to take calls without holding phones.

Triple universal ports including 3.5mm AUX, RCA stereo output and USB drive slot, supports wired audio output and direct U-disk music playback.

Compact all-in-one audio converter box easily upgrades traditional non-Bluetooth speakers, amplifiers and car stereos to wireless Bluetooth audio devices.

Simple one-button operation, automatic device reconnection after power off, plug-and-play design without complicated software or extra drivers.
