ZERFUN S67 portable PA speaker

The ZERFUN S67 is an 18W portable PA speaker with a built-in 2.4G wireless receiver. It is designed for teachers, tour guides and coaches who need hands-free voice amplification in classrooms, tour groups or sports sessions. The system includes a miniature lavalier microphone that weighs 11g.

Lavalier microphone and 2.4G link

The 11g lavalier microphone clips onto a collar and pairs automatically when the speaker is powered on, removing cables that restrict movement. The 2.4G wireless connection allows the wearer to move freely while the speaker projects 18W of sound with DSP anti-howling processing. A 2000mAh battery provides up to 24 hours of continuous use and recharges via Type-C.

18W output with DSP anti-howling

The 18W dual voice coil speaker combined with the DSP chip determines whether the unit can cut through background noise in a large room or outdoor setting. Buyers who need higher output power for auditoriums or who require multiple wireless microphones simultaneously will find this model does not meet those needs.

Questions about this item

How long will the 2000mAh battery last before it needs replacing?

The 2000mAh lithium battery provides up to 24 hours of continuous use per charge and recharges via the Type-C port; typical lithium cells retain useful capacity for several hundred charge cycles.

What limits continuous operation during a full day of use?

Battery life is the primary limit; the unit runs for up to 24 hours on a single charge, after which it must be recharged via Type-C before further use.

How much heat or noise does the 18W speaker produce when running all day?

The 18W inner-magnetic dual voice coil speaker with DSP anti-howling technology operates quietly without audible fan noise; the compact enclosure stays cool during extended voice-amplification sessions.
