Compact 10W Voice Amplifier for Group Speaking

The SHIDU S258 is a pocket-sized PA speaker rated at 10W output. It is designed for teachers, tour guides, fitness instructors and coaches who need to address up to 120 people without straining their voice.

Clip-On Setup with Simple Charging

A detachable rear clip secures the amplifier to a belt or pocket, while the wired headset microphone plugs into the 3.5mm port. The built-in 1800mAh lithium battery charges via DC 5V in 3-5 hours and delivers 12 hours of speech amplification or 10 hours of music playback. No drivers or pairing are required; the only common issue is forgetting to charge the unit overnight.

Check Your Playback Sources Before Buying

The amplifier accepts TF (Micro SD) cards and USB flash drives for MP3 playback, and the microphone port doubles as an AUX input for phones or computers via a 3.5mm cable. Verify that your audio files are in a compatible format and that you have a suitable USB power source for recharging. The package includes the amplifier and the wired headset microphone only.
