SHIDU 35W Power Voice Amplifier with Bluetooth Wireless Lavalier Microphone, Portable Teacher Mic with Speaker Personal Clip On Microphone System for Teacher Meeting Training-M500 (Black)

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 voice amplifier works extremely well and has been a huge help for my daily teaching and meetings. The sound is loud and clear without any distortion, even in a larger room. The 35W output is more than enough to project my voice comfortably without straining. The wireless lavalier microphone is lightweight and very convenient—I can move around freely while speaking, and the connection stays stable. Bluetooth works smoothly for playing audio, and the speaker quality is surprisingly good for such a compact device. I also love how portable it is. The clip design makes it easy to wear, and the battery lasts long enough for a full day of use. Setup was quick, and all the controls are simple and intuitive.

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 love the sleek black design and how easy it is to clip on and get started. Perfect for teachers, trainers, or anyone who needs to project their voice clearly. A game-changer for my daily routine! 🎤📢✅

We ordered this for calling bingo at our senior center. For our purposes it works fine, especially since the acoustics in the building cause sound to be carried good anyway. This would not be adequate for large conferences or meeting halls. The speaker is smaller than I thought and the sound is not as dynamic as I would have hoped it would be. If you get the microphone near the speaker it will have a piercing "feed-back!" If the microphone is not kept stationary, it will pick up static sound from rubbing against clothing. When using the speaker it is best to place the speaker on a wall or table where it can be stationary or there will be "popping" and "cracking." The speaker comes with a "sling" for placing it on ones shoulders but I do not recommend carrying it. It's good for calling bingo at a senior building. I'm sure it would be adequate for small office meetings or class room settings. Anything larger would require a larger sound system.

It is a powerful and reliable tool for teachers, trainers, and presenters. Its Bluetooth connectivity and wireless lavalier microphone offer excellent mobility and clear sound. The 35W output delivers impressive volume for classrooms or meetings without distortion. It’s lightweight, portable, and easy to clip on, making it convenient for daily use. Battery life is strong, and build quality feels durable.

I’m very happy with this product! The sound is loud, clear, and covers a large area easily. The microphone is comfortable and the Bluetooth connection is stable. The battery lasts a long time, which makes it perfect for teaching, presentations, or outdoor use. Compact and lightweight easy to carry anywhere. Definitely worth the price

I liked EVERYTHING about this Shidu Voice Amplifier, UNTIL I went to use it for the 3rd time and it stopped turning on altogether, even after charging it overnight. I tried reaching out to Shidu and apealed to their 24 month warranty through their support chat and no answer. I saw others who had the same experience and who rated it a 1 as well. It is too bad, I could have really used this amplifier and now not only do I not have one but also don't have the $70 I spent.

The product is working but afer 3 days the battery was low i hope I can exchange. Thank you so much Dor your help.
