Bring wireless audio to devices that only support wired sound. The UGREEN 30445 is a Bluetooth audio receiver designed to connect your smartphone or tablet to headphones, home theater systems, or speakers using standard audio outputs. With Bluetooth 4.1 support and a working range of up to 10 meters, it helps you enjoy music and calls with fewer cable hassles—ideal for living rooms, bedrooms, and desk setups where you want clean, organized audio connections.
This receiver includes both 3.5mm audio output and L/R RCA (female) audio output, making it versatile for different speaker and amplifier inputs. If your speaker or sound system has a 3.5mm AUX port, you can use the 3.5mm output for quick pairing. For home theater or older audio equipment that uses RCA inputs, the 2RCA output provides a straightforward way to route left/right audio channels. This dual-output approach is especially useful when you want one adapter to work across multiple audio devices.
Powered by Bluetooth 4.1, the UGREEN 30445 is built for stable wireless audio streaming within a typical 10-meter range. The frequency response is 20Hz–22kHz, supporting a wide audible spectrum for music playback. With an output power of 25mW and an SNR of 100dB (RL=16Ω), it’s tuned for clear sound reproduction when paired with compatible headphones or speakers. For buyers in Bangladesh looking for a practical Bluetooth audio receiver, this model is a convenient solution for upgrading wired audio gear without replacing the entire speaker system.
The UGREEN 30445 comes with battery support and uses Micro USB (5V) for power supply/charging. It can provide up to 8 hours of operating time, which is helpful for daily listening sessions, small gatherings, or casual home use. Approximate charging time is about 2 hours, so you can recharge quickly and get back to wireless audio. This makes it suitable for setups where you may not want to keep the receiver connected to a power outlet all the time.
Before purchasing, check the input ports on your existing audio equipment. If your speaker supports 3.5mm AUX, the 3.5mm output is the simplest match. If your home theater or amplifier uses RCA inputs, the 2RCA output will fit directly. Also consider placement: keeping the receiver within the 10-meter working range helps maintain reliable connection quality. For best results, pair the receiver with your smartphone or tablet and then connect it to the appropriate audio input using the correct output type.
The package content includes the UGREEN 30445 Bluetooth audio receiver. It comes with a 1-year warranty, offering added confidence for long-term use. The product is listed as part number 30445 and is made/assembled in China. If you need a dependable wireless audio adapter for home theater, speaker systems, or headphone setups, the UGREEN 30445 is a strong choice due to its flexible 3.5mm and 2RCA output options.
