SHIDU 30W Wireless Voice Amplifier, IPX6 Waterproof Portable Bluetooth Voice Speaker with 2500mAh Large Capacity Rechargeable Battery PA Systems Speaker for Teachers,Classroom, Meetings and Outdoors

I seriously love this voice amplifier! I teach group fitness and it makes a huge difference—my class can actually hear me over the music now. The wireless mic is super convenient, and I can move around without getting tangled in cords. It’s lightweight, comfy, and the battery lasts all day. No more yelling or straining my voice. If you teach fitness, you need this in your life!

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!!!!!!

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 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.Update: The company contacted me and offered to refund my money. I appreciate them standing behind their product and compensating when it doesn't work. Thank you!

This worked really great for about 10 months. Now it sounds like the mic connects but no sound is transmitted other than a tiny bit of static when it connects. It would be great if there was more info on warranty or if there was a way to replace the headset.It was a little frustrating that the headset would last me about two 2 hour tours but the speaker would last all day. It would be great if the battery was bigger in the headset to match the longevity of the speaker battery.Overall it was well built and worked really great while it worked.
