Altoparlante Bluetooth portatile Tellur B8 con microfono integrato — wireless, portatile

Tellur B8 is a compact wireless audio device that combines a Bluetooth speaker, FM transmitter and hands-free microphone. It connects to smartphones and tablets via Bluetooth 5.0 and can play music from Bluetooth, microSD card or USB flash drive. The unit features a display showing FM frequency and volume, a dedicated bass button to enhance low frequencies, dual USB ports (one for charging external devices and one for music playback) and power-off memory that restores the last FM frequency and song.

Advantages

The device supports three playback options — Bluetooth, microSD and USB — providing flexible connectivity. Bluetooth 5.0 ensures stable wireless streaming while the built-in microphone enables clear hands-free calls. A bass button increases low-frequency output for a fuller sound, and the dual USB setup separates charging (5V/2.4A) from media playback (5V/1A). The transmitter covers the FM range 87.5–108.0 MHz and accepts MP3/WMA/WAV/FLAC formats.

Suitable for

• Listening to music from phone or USB/microSD while driving (FM transmission)
• Hands-free calls in car or on the go
• Portable audio for travel, outdoor activities and small gatherings
• Charging mobile devices from the dedicated USB charging port

How to use

Plug the Tellur B8 into a 12–24 V power socket (car cigarette lighter). Pair a smartphone or tablet via Bluetooth 5.0 or insert a microSD card / USB flash drive with supported audio files. Set an unused FM frequency on your car radio within 87.5–108.0 MHz and match the transmitter display to that frequency to stream audio through the vehicle speakers. Use the bass button to adjust low-frequency emphasis and use the built-in microphone for hands-free calls. Use the dedicated USB charging port to recharge other devices while playing music from the second USB or microSD.

Recommendations

For best reception, choose an FM frequency with minimal local radio interference and ensure inserted microSD/USB media do not exceed 32 GB and contain supported audio formats. When charging external devices, use the dedicated charging USB port to prevent interruptions to music playback.
