Ultra-Compact Wireless Voice Amplifier

The ZERFUN S67 is a portable PA speaker weighing 11 g, built for teachers, tour guides and coaches who need hands-free voice reinforcement throughout the day. Its 2.4 G wireless lavalier microphone pairs automatically on power-up, removing cables that restrict movement during classes, tours or training sessions. The integrated speaker delivers 18 W of clear output suitable for small to medium indoor spaces.

Upgrade from Wired Megaphones or Smartphone Speakers

This system replaces bulky wired megaphones and under-powered phone speakers that strain the voice or fail to reach a full room. The jump is worth it when you need all-day wear comfort, instant wireless freedom and consistent coverage without feedback during lessons, guided walks or coaching drills.

Sustained Use with DSP Anti-Howling Stability

An inner-magnetic dual voice coil driver and self-developed DSP chip suppress howling continuously, keeping speech crisp during extended sessions. The LED display shows battery level, volume and mode in real time, while TF card, USB, Bluetooth and AUX inputs allow background audio playback without interrupting voice amplification.
