Blaupunkt BT50BB Portable Stereo Speaker Black

The Blaupunkt BT50BB Portable Stereo Speaker Black is a compact, battery-powered Bluetooth speaker designed for mobile use. It delivers stereo sound with 2 x 15 W RMS amplification, includes an FM radio with memory for up to 60 stations, a MicroSD card player (supports cards up to 32 GB) and an AUX input for non-Bluetooth devices. The built-in 4000 mAh battery charges via micro USB and provides up to 10 hours of playback. The speaker is water-resistant and also functions as a powerbank to charge other devices.

Advantages

The speaker combines wireless Bluetooth (A2DP) and wired connectivity, allowing playback from smartphones, tablets, laptops and older MP3 or CD players via AUX. Its 2 x 15 W RMS output and stereo configuration deliver louder and clearer sound compared with typical single-driver portable units. The integrated FM tuner with 60-station memory and the MicroSD player offer flexible playback options without a connected device. Water resistance increases usability outdoors, and the Powerbank function provides emergency charging for mobile devices.

To play from a MicroSD card, insert a compatible card (max 32 GB) into the slot and use the speaker controls to navigate tracks. For FM radio, switch to the radio mode and use tuning controls to scan and save stations. To connect an older device, use a 3.5 mm audio cable and the AUX input. Use the built-in controls to adjust volume and playback; when needed, connect another device to the speaker’s USB output to charge it via the powerbank function.

Recommendations

Keep the speaker’s charging port and connectors dry and clean. Although the device is water-resistant, avoid full immersion and prolonged exposure to heavy rain. Use MicroSD cards formatted to FAT32 and do not exceed 32 GB capacity. Charge the battery regularly to maintain capacity and do not leave the battery fully discharged for extended periods.
