SHIDU M500-U66-Black 35W Voice Amplifier with Wireless Lavalier Mic
Product description
Some speaking settings call for hands-free amplification, others benefit from a compact system that can move between teaching, tours, and presentations. The SHIDU M500-U66-Black combines a 35W voice amplifier with a wireless lavalier microphone for spoken use.
The clip-on mic can attach to a collar or be held in your hand, offering an alternative to wearing a headset while you teach or explain. Its 2.4G wireless connection gives you room to move as you speak.
Bluetooth 5.3 also lets you connect a cell phone to play music, so the same portable speaker can support spoken instruction and audio playback.

Practical tips
Clip the microphone to your collar or hold it while speaking, then keep the mic head away from the speaker and avoid pointing it directly at the speaker. This helps prevent the sharp feedback sound that can occur when the microphone picks up the amplified audio nearby. For an activity that includes music, connect a cell phone over Bluetooth 5.3 and use the amplifier for playback as well as voice.
The manufacturer describes the amplifier as having AI noise reduction. Buyers have highlighted clear, strong sound and its usefulness for teaching and presentations, along with its compact size and reliable operation. Some buyers are less convinced about its value, so the most relevant choice factor is whether a portable voice amplifier and wireless lavalier setup suit your regular speaking needs.
Tips for day-to-day use
Charge the rechargeable battery with the included Type-C charging cable. For a class, tour, or group instruction, position the speaker and microphone so they face away from each other and remain separated. The clip-on format is useful when you want to speak while moving around a room without wearing a headset, holding the mic is another option when that suits the activity better.
Practical questions
Can I play music through the amplifier? Yes. Pair a cell phone over Bluetooth 5.3 to play music through the speaker, making it useful for sessions that combine spoken guidance with audio.
How long can it run between charges? The 3,100mAh battery is rated for up to 16.5 hours of continuous use. Charging takes about 2–4 hours with the included Type-C cable.
How far can I move from the speaker with the microphone? The stated wireless connection distance is up to 40 meters/131 feet. Keep the microphone away from the speaker and do not point it directly at the speaker to help avoid feedback.
When it makes sense
This amplifier is a practical fit for teachers, tour guides, fitness instructors, and speakers who need to project their voice during a session. The wireless lavalier mic supports hands-free instruction, while Bluetooth music playback adds flexibility for classes and presentations. Choose it when portable voice amplification and a clip-on microphone are more useful than relying on an unamplified voice or wearing a headset.
