## Long description

UGREEN ML CM671 is a compact Bluetooth 5.3 adapter designed to add wireless audio connectivity to devices with a 3.5 mm mini‑jack. Operating as both a receiver and a transmitter, this small unit enables streaming to Bluetooth headphones or speakers, and can also send audio from a phone or laptop to wired audio systems. The built‑in 300 mAh battery supports portable use and the package includes an airplane headphone adapter for compatibility with in‑flight entertainment systems.
Advantages
The adapter supports the Bluetooth 5.3 standard for improved connection stability and reduced latency compared with older Bluetooth versions. Its dual-mode design (receiver/transmitter) provides flexibility for multiple scenarios without the need for separate devices. The 3.5 mm mini‑jack interface ensures broad compatibility with headphones, car stereos and portable speakers. The included airplane adapter makes the unit ready for travel, while the rechargeable 300 mAh battery allows for untethered operation when wall power or USB is not available.

How to use
Charge the adapter fully using a compatible USB power source before first use. Switch the unit to the required mode — receiver to accept Bluetooth audio from a phone or transmitter to send audio from a source device — then connect the 3.5 mm plug to the target device's headphone or line‑in socket. Put your Bluetooth headphones or speaker into pairing mode and initiate pairing on the adapter; indicator lights will confirm successful connection. For in‑flight use, attach the included airplane adapter to the airline jack, set the device to the appropriate mode and pair with your Bluetooth headset if supported by the aircraft system.
