Questions about this item

Which version of the Dunudun ZX-01 S17 should I pick for a full day of teaching?

The single model offers 8 W output and 12 to 15 hours of voice amplification per charge, covering a typical teaching day without needing a recharge.

What does the 8 W output mean when I am speaking to a class?

Eight watts drives the speaker loud enough for 25 to 100 people in a small or medium room, letting you talk at a normal level while the amplifier projects your voice clearly.

What connections does the 3.5 mm port support and what does it limit?

The 3.5 mm jack works as both the wired headset microphone input and an AUX line-in for external audio sources; it does not carry Bluetooth or FM signals, which are handled by separate internal modules.
