35W Voice Amplifier for Teachers Bluetooth Wireless Lavalier Mic

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 Voice Amplifier has been an excellent purchase! The sound is loud, clear, and easy to hear, even in larger classrooms or outdoor settings. The wireless microphone connects quickly and allows me to move around freely while teaching without losing sound quality. I also love the Bluetooth feature, which makes it easy to play music or other audio when needed. The battery lasts for hours on a single charge, and the amplifier is lightweight and comfortable to carry throughout the day. It's simple to set up and use, making it a great option for teachers, presenters, coaches, or anyone who needs reliable voice amplification. I highly recommend it!

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.

I am blown away by how good this little mic/speaker combo is. If you remember the Walkman, that's about the size of the speaker. It was easy to pair, and has great sound for a presentation to 75 people spread out around a room. I charged it before use but it arrived with a decent amount of battery life. I didn't wear the speaker though. It seemed as if there was feedback, but maybe that's user error, and I'm going to try it at home. For my presentation, I put it at one side of the room.

I ordered this on July 2, 2026. It seemed to work really well for the first few days of use, then went in stubborn, useless mode. Even though the return date is passed, I tried to contact the seller to see if they might send a replacement, a WORKING UNIT! This is what I wrote to them: This does NOT work! It is fully charged. I have the fully charged microphone turned off. I turn the speaker unit on, it displays "10", it switches to 00:00 and shows the fully charged battery icon. Within 5 seconds, it shuts off. Their reply was simply, that I missed the return date. SO... if you are willing to throw away your good, hard earned money, go ahead and buy this garbage. It did sound good the first few times of use, then poof, garbage. Don't waste your time or money. I needed this due to unilateral paralysis of my larynx. I don't have a voice without a voice amplifier. I am VERY DISAPPOINTED WITH THIS PRODUCT AND SELLER!!!

I have a paralyzed vocal cord, I bought this amplifier for my speaking engagements, and now I wish I would have bought this two years ago! It is easy to use, volume and sound quatlity is amazing.

Yes, it works great!

Has terrible sound. I wanted to use this at a conference, but the sound quality is pretty bad. Sounds unprofessional and like you are talking through a radio....

It doesn’t work .. i was rewally looking forward to this device.. very disappointed. I wish they can exchange what i got with a working one .. but its just say return .. so i applied for a return.

Nos funciona muy bien para brindar visitas guiadas, tiene una potencia bastante correcta y una buena calidad. Nos gusta particularmente que se pueda manejar la sensibilidad del micrófono para encontrar el balance justo entre subir el volúmen y no tener que mantener pegado el micrófono a tu boca

Loud and clear

Es un excelente producto, se escucha claro y fuerte. Lo uso para dar clases y me ha ayudado a mejorar el cuidado de mi voz.

Faulty only after 3 months use. Very poor quality.
