SHIDU 30W Voice Amplifier with Wireless Microphone, IPX6 Waterproof Amplifier Wireless & Wired Microphone Bluetooth Speaker Personal Megaphone for Teachers Meeting Speech Outdoors-M1000

This is actually sounds really good. I’m surprised of it’s quality and how good it works.

Tried two others which claimed similar wattage but were either very echoey or poor quality— funnily enough from the same manufacturer. This one is much much better and definitely fits the bill.

I had purchased a similar unit about 5 years ago. It was a smaller wattage output. It worked great until it started to not hold a charge. It was used for only 2 one hour classes a week and after these last few months it could no longer hold a charge so the headset stopped working 3/4 of the way through class. I decided to purchase a different brand which didn’t work out so well. I sent that back and bought this unit which works great. It has great sound quality and is easy to use.

I got this for my wife, who is a primary school teacher. It has a really good sound quality and It's nice that it is wireless, so she doesn't have to carry around the speaker in order to use this. This item was really helpful during the Covid period as the students weren't wanting to come in closer. This can get really loud--one of her coworkers commented that this was a great recommendation for other teachers and the build quality of the item. Few are the pro and cons I found for it Pros Nice build and sound quality for the price Nice battery backup for the provided size Cons Sometimes it may be little heavier to carry around

Nice,clear,loud

I really loved this voice amplifier when I first received it at the end of October. It worked perfectly. The sound was clear, the volume was strong, and it made teaching so much easier. As a substitute teacher who only works about once a week, I’ve used it fewer than 10 times total. However, after taking a break over winter and returning to subbing in February, I found that the amplifier was no longer functioning properly. Even after fully charging it, the device would turn on, work for a minute, and then completely shut off. I also made sure the microphone was charged, but my voice still wasn’t amplifying. Considering how lightly it has been used, I’m extremely disappointed in the durability and longevity of this device. It simply did not hold up over time, despite minimal use. Unfortunately, I’ve already passed the return window, which makes this even more frustrating. I hope the company improves the battery life and overall reliability, because when it works, it’s a great tool for teachers. Sadly, my experience has been very disappointing.

Bluetooth mic stopped working after 1 use. No replacement is sold on Amazon either. 1 star review. *Update* Sept 2025 Several attempts were made to reach out to the company to include the email and Whatapp listed on the company page in Amazon. No response at all from either till I posted this review. They then reached out offering a full refund which I accepted and they fulfilled. I’ve added 2 stars. The strange part is that the unit works fine. It’s just the Bluetooth head mic that stopped working after 1 use. The issue is no replacements are available which would have easily solved the problem. Hope this helps.

Incredible quality. Very clear voice.

Parece un equipo genial y la potencia y portabilidad es excelente, no pudo negar eso. Estaría absolutamente perfecto de no ser por que se va el sonido de manera intermitente. Al principio era muy esporádico pero después de algunas semanas ya se me dificulta mucho dar la clase por la cantidad de interrupciones. Trate de probar la línea auxiliar y el Bluetooth para comprobar si no era el micrófono inalámbrico pero pasa lo mismo con todos los medios. Intentaré contactar al vendedor y hacer valida la garantía. Es una lástima porque si no fállese es justo lo que necesito para dar clases sin forzar la voz!!!!!!

Debería incluir un micrófono inalámbrico, la diadema que trae funciona muy bien pero algo incómoda. Mi conclusión es que es un dispositivo que merece la pena para quien necesita no forzar tanto la voz pero sí hacerse escuchar (profesores, tours, etc.)
