## Description

Teachers, tour guides, and fitness instructors who need to project their voice can pair the SHIDU M500-U66-Purple with its wireless lavalier microphone and portable speaker.

Its 35W output is designed for voice amplification, while a separate Bluetooth 5.3 connection lets you play music from a compatible device.

Choose it for speaking support during lessons, tours, training, or presentations. The wireless mic and speaker connection is listed at up to 131 feet, giving you room to move while addressing a group.

## At a glance

This purple voice amplifier combines a 35W speaker with a wireless lavalier microphone. The microphone uses a 2.4G wireless connection, while Bluetooth 5.3 supports music playback from a phone or other compatible device. That distinction makes the setup useful for both spoken instruction and sessions where audio tracks accompany the activity.

The rechargeable battery is rated at 3,100mAh, with up to 16.5 hours of continuous use. Charging takes 2–4 hours, and a Type-C charging cable is included. The stated effective coverage is about 22,604 square feet (2,100㎡), giving instructors and guides a published coverage figure to consider for their space.

## How it fits

For a class or guided tour where speech is the priority, the clip-on lavalier keeps the microphone positioned for hands-free instruction. If the session also needs music, Bluetooth playback adds that option without changing the main role of the amplifier. It’s a practical contrast with choosing a speaker just for music: this system pairs playback with a dedicated voice microphone.

The included set comprises the speaker, lavalier microphone, and manual. The enclosure is made of ABS. The manufacturer advises keeping the microphone and speaker apart and pointing them away from each other to help avoid sharp feedback sounds.

Buyers often highlight clear, strong sound, compact size, and usefulness for teaching and presentations. Some also appreciate the battery life and quick, stable connections. Opinions on value are mixed, so the strongest reason to choose this model is its specific combination of portable voice amplification, a wireless lavalier, and Bluetooth music playback.

## Tips for day-to-day use

Clip the microphone to your collar or hold it in your hand, then keep it a short distance from the speaker and facing away from it. This placement follows the manufacturer’s guidance for reducing feedback. For a lesson or tour, the wireless link can help you move around while speaking, for a workout or training session, Bluetooth music playback can accompany spoken cues.

A full charge is listed as taking 2–4 hours, and the stated continuous-use time is up to 16.5 hours. Charging uses the included Type-C cable. For a group session, position the speaker where the audience can hear it and keep the lavalier away from the speaker itself.

## Questions before you buy

**Can I play music from my phone?** Yes. Bluetooth 5.3 supports music playback from a compatible phone or other compatible device. The lavalier microphone uses a separate 2.4G wireless connection.

**How long can it run between charges?** The built-in 3,100mAh battery is rated for up to 16.5 hours of continuous use. Charging takes 2–4 hours using the included Type-C cable.

**What comes in the set?** The listed components are the speaker, lavalier microphone, and manual, so the main voice amplification pieces are together in one set.

## When it makes sense

A solid pick if you regularly address a group and want a portable speaker with a clip-on wireless mic, rather than a music-only speaker. Its 35W output, separate Bluetooth music playback, and rechargeable battery make it suited to lessons, tours, fitness instruction, and presentations where spoken guidance is central.
