The SHIDU 35W Power Voice Amplifier (M500) is absolutely amazing! The sound is loud, crisp, and clear—even in large classrooms or training rooms. The Bluetooth wireless lavalier mic is super convenient and allows me to move freely without being tied down by wires. It’s compact, lightweight, and the battery lasts all day.

I bought this 35W power voice amplifier with Bluetooth wireless lavalier microphone mainly for presentations, and it has worked really well. The sound is loud, clear, and easily fills a room despite the compact size. It’s lightweight and easy to carry, which makes it comfortable for long sessions. I really like the clip-on lavalier mic design. You can clip it to your collar or hold it in your hand, so there’s no need to wear a headset. This reduces discomfort and feels more natural while teaching or explaining. Bluetooth connection is smooth and stable, and setup is quick. The amplifier itself is small but powerful, as shown in the comparison photo I uploaded. Battery performance is solid for daily use. One important note from my experience: if the microphone head is too close to the speaker, it can produce sharp or strange sounds due to sound feedback. This is normal, just keep some distance and it works perfectly. Overall, a great choice for teachers, trainers, and presenters.

This amplifier exceeded my expectations from the first use. Its 35 W power combined with the 2.4G wireless Lavalier microphone offers clear sound quality, without noise or interference, ideal for covering large spaces such as classrooms or living rooms with more than 300 people. The connection is stable and the audio transmission via Bluetooth 5.3 works without complications. The design makes it very comfortable, no more ear pain for uncomfortable headphones. The lightweight clip allows you to carry it around your neck or hand without discomfort. In addition, the long battery life and fast USB-C charging make it perfect for intense days. It is compact, easy to use and very versatile. I have used it to teach, give talks and outdoor activities, and it has always responded with excellent performance. Without a doubt, an indispensable tool for those who need to amplify their voice without sacrificing comfort or quality. 100% recommended

I am a PE teacher and use this in my classes. Plenty loud when using the mic, just wish the battery lasted longer than one day. I tried the bluetooth function to play music from my phone. Not very loud.

This SHIDU voice amplifier is perfect for teaching and presentations. The wireless lavalier mic has great sound quality with no noise, and the 40m range is impressive. Lightweight and comfortable to use without a headset. Battery lasts all day, and Bluetooth is a great bonus. Highly recommended!

I bought it for my classroom and it worked great! However, after 4 months of daily use in the classroom, it stopped working out of nowhere. The speaker turns on and after a minute it shuts off. Double checked to make sure it was charged. Looked up videos to make sure microphone and speaker was paired correctly, and still didn't work. I've had cheaper amplifiers that lasted years. Disappointed.

This voice amplifier works really well and is very easy to use. The sound is clear and loud enough for teaching or presentations. It comes with a microphone included, which is very convenient. I also like that it can be used as a speaker to play audio, making it even more versatile. Compact, practical, and definitely worth the purchase.
