Portable Voice Amplifier with Anti-Feedback

The BFKK amplifier delivers clear voice projection for teachers, coaches, tour guides and meeting presenters. A built-in anti-feedback circuit removes howling, while the 9.7 mm directional microphone reduces background noise. Professional audio processors ensure every word reaches large audiences without vocal strain.

Bluetooth Speaker and Hands-Free Wear

Beyond amplification, the unit functions as a Bluetooth speaker with AUX input for music playback from phones or tablets. Voice and music can run simultaneously. A 2500 mAh rechargeable battery provides 16 hours of continuous operation. An adjustable neck strap, waist clip and lightweight ergonomic body allow comfortable hands-free use while moving.

Ideal for Mobile Speakers, Not Fixed Installations

Suits professionals who need portable, all-day voice support without cables or a PA system. The single microphone input and integrated speaker limit coverage to personal range, so venues requiring multi-mic mixing, rack mounting or wider dispersion should consider alternative solutions.
