M800 UHF

I am a teacher and just used this product with my class. It was very easy to set up, charge, and get it started. I like that the speaker has a clip or a strap so it doesn’t matter what type of outfit I’m wearing that day. The microphone is lightweight and convenient. The sound level and the quality was not bad. I have not been able to test the battery life yet, but I’m hoping it would last all day before needing a charge. Overall, the sound quality was loud and clear enough for my students to hear. Next step: test it outdoors!!

We just bought this PA system less than 2 weeks with Wireless UHF headset to replace existing inexpensive wired PA system. My wife primary use it in the class room. Per her opinion, this UHF headset works really well and the speaker volume loud enough for 30+ students classroom. (She doesn’t have to screaming anymore) Since its wireless, the speaker can be placed in other site of classroom without next to the headset. It can be used a regular speaker pair with any Bluetooth devices. This speaker volume is design more for larger room, (I have tried to tune down the volume to lowest but still very loud). One thing I can’t figure out is what kind of batteries are used in the speaker and headset. (i.e. Lithium battery? No member effect. Which means it can be charged anytime). If the battery goes bad, can we replace the battery? The only defected item is the cable used to charge the headset. The headset is having issue to get full charge from day one. After troubleshooting for a while with my other similar cable, the headset finally has the steady red charge light till full charge. We need to get a replacement charge cable from the seller for sure.

As a teacher, I had to use an amplifier during Covid, but all the ones I had used felt like a you and was mostly plastic. This amplifier not only has a Bluetooth mic, but it has a professional sounding microphone that is loud and clear, and lasts a very long time in just once charge. It’s very well built and easy to use. Highly recommended for anyone who needs a voice amplifier for either teaching or other needs!

The very first time I tried this system out in my home, it worked perfectly! I was able to connect my phone Bluetooth to play my music, and I could use the headset simultaneously. I was able to walk away from the speaker/receiver about 15 feet and still have quality output. The next time I used this was instructing my water aerobics class. I couldn't connect my phone to play my music (luckily I brought a backup speaker). The headset only allowed me to get about 5 feet away. The speaker sat on the pool deck at the edge while I was in the pool. The sound was still very good and I'm glad I have it so my class can hear me, but I can't stray far from the side of the pool. This same experience was repeated the 2nd time I tried to use it for my class. Both times everything was fully charged. Giving it 3 stars because this works so much better than having nothing, but not more because of my reasons mentioned.

This microphone is a total game changer for the classroom. It is super easy to set up plug the box into the wall and use the wireless headset- channelling your inner pop star. I use this microphone in my gifted and talented classroom and it is the perfect tool for transitions, behavior management and teaching my mini lessons. The quality is clear and It really saves my voice and helps all students focus. I will be purchasing another one so my students can use during presentations! Recommend to ANY teacher of any grade level!!

Most features worked as advertised. Sound quality needs to improve. Sound like the drive through cashier. Connected to Bluetooth device and sound quality needs to improve for the price.

Works just as advertised.

I am loving this voice amplifier! I am a third grade teacher, and the worst thing is when I lose my voice! This amplifier makes it possible for all my students to hear me during lessons. I love how I am able to wear the microphone and have the bluetooth amplifier elsewhere in the room; the amplifier has the accommodation of clipping on a strap (provided with this purchase) for times that I am outside of the classroom. I can't wait to use this accommodation on field trips! This product is very easy to use!!! The reason I gave a 4 for sound quality is because I wish the sound was a bit louder, but it is enough for what I will be using it for. I gave a 4 for battery life because I also wish microphone's battery would last longer than 3-5 hours, but I will be able to charge it during my lunch period if needed.

I purchased this for my dragon boat coaching job. It has the perfect volume and range for my purposes. Unfortunately during a regatta, I dropped the headset into the water, never to be seen again :-( I contacted the seller and asked if I could purchase a replacement and they were very helpful. They sent me a replacement for free! That's what I call customer service!

Works for what I need it for. I’m not sure if it’s the product or maybe I just had it too far away from me, but it would cut out randomly. I also don’t want it too close so I get feedback. I just have to find the sweet spot I guess. It also takes a minute for the microphone to connect and actually come through on the speaker, so you just have to wait a few seconds before speaking. It’s a trial and error thing. I teach yoga, and I have a very soft voice, I don’t like or want to yell. Again, decent for what I need it for and has surprisingly good and loud sound for the price.

18W output doesn't come good through the bluetooth microphone. Ahuja 20 dp speaker gives more output even it is 12W. While teaching, the voice is not properly captured and released to the audience. I expected a much better voice output. But bluetooth volume provides higher power. I am disappointed by the microphone output. Is it possible to connect this amplifier with a better external wireless microphone?

but it loses now the contact very often. My wife is teaching yoga lessons and uses it for it. Setting the volume with the headset is also not working really well anymore. And it became quiet undertone. And it is not really rising the volume anymore. We just got this about a year. Update: I found out that the battery of the headset is too weak. So that it is not working anyway I opened it in the hope to replace the battery. This is not possible. Shortly after the loudspeaker itself died. Used it a bit for my laptop to get a better sound. Really sad. Spent so much money and it did not even last a year. Stay away from it.

This is perfect for classroom teachers to amplify their voice during lessons, as well as for students to better hear classroom instruction and direction, especially for those who are hard of hearing. As a dance coach, it is perfect to use for counting while the music is playing, in order for the dance students to better move according to the correct timing and rhythm. I love that it is wireless, light, and portable. The rechargeable battery lasts a long time and is fast-charging. It's really easy to use and doubles as a bluetooth speaker, so you can play music at the same time from it while amplifying your voice! A teacher must-have!
