How long does the battery last on a single charge?

It provides up to 12 hours of continuous amplification on a single charge. It is designed to reliably last through a full school day or a long tour without needing to recharge, giving you peace of mind during your busy schedule.

Will there be any feedback or howling noise when using the microphone?

Our voice amplifier is engineered with advanced anti-whistling technology to minimize feedback. To ensure the performance, simply keep the microphone at a reasonable distance from the speaker and avoid pointing the mic directly at the speaker unit.

How many people can this amplifier cover? Is it loud enough for a large room?

With a powerful 10W output, this device can effectively cover up to 11,800 sq.ft, making it loud enough to be clearly heard by groups of up to 120 people. It is perfect for filling large classrooms, small halls, or outdoor tour settings.

Is it comfortable to wear all day for teaching or guiding tours?

Yes, it is ultra-lightweight at only 0.36 lbs. It comes with a detachable back clip and an adjustable waistband, allowing you to wear it comfortably on your belt, pocket, or over your shoulder for hours without feeling fatigued.

Is the setup complicated, or does it pair automatically?

It is extremely easy to use. The wired microphone headset is "plug-and-play," meaning there is no complicated pairing process required. You simply plug it in, turn it on, and you are ready to speak immediately.
