Easy to set up and use
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!!

UHF wireless headset, Loud speaker, Good for classroom
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.

Game changer!!!
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!!

Not all it's hyped up to be.
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.

Best Voice Amplifier I’ve Used!
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!

Needs to improve for the price.
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.

Light and easy to use.
I teach a dancing class and I needed something that I could plug my IPad into and also give voice instructions with. The sound quality was as expected not Bose yet good enough. The setup is very light and easy for me to carry (what I was using before was becoming very difficult for me to lift). No complaints. If I have other input in the future I'll update my review. This is a follow-up to the above: I have been teaching clogging classes for 15 years. When I started I used a school record player, advanced to a cassette player and then to a CD player which included a mixer amp and a sizable speaker. This worked well for the class size and the room I was in but was very cumbersome (heavy) to move about. Due to reduced class sizes and my growing inability to move the heavy equipment around I started looking for something more up to date and smaller. I switched over to an Ipad for the music but I still needed an amplified speaker and hands free microphone. The 18W voice amplifier meets my needs. The Ipad, using the app “Amazing Slowdowner” provides the variable speeds needed for teaching new dances, and your hands free microphone and amplifier mixes my music and voice cues. To control the volume I set the amp at just about max and vary the Ipad and microphone volume as needed. This is a good solution for a small group of dancers in a limited space. I would not recommend it for large groups of dancers since the power is not enough to overcome the noise that a large group of dancers make. The support from Linda at HaoYueTechNet has been great and I can not thank her enough.

Good but you have to basically eat the mic
I bought this for teaching circus arts. The sound from the speaker is nice and loud. Very nice that it switches seamless back and forth between your voice and the music. The only problem is the mic. I have to use a headband to keep it on and to even have my voice amplified I need to basically eat the mic (without the little foam part the feedback sucks). So it’s great when I have to teach with a mask but that’s not too often

Best Teaching Tool Ever
This is an amazing tool to have as a Supply Teacher. When I pull this out or walk in wearing the headset, students become intrigued. When I turn on the little amp/speaker, they stop talking and start to listen in a way that nothing else does. It saves my voice and students learn more. Best money spent for teaching!

Using for yoga, does what I need it to do
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.

Disappointed with the mic volume. But bluetooth volume is awesome.
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?

Great for classroom
Used it in a classroom of 40 students. It works perfectly, has good sound quality, and is easy to connect.

Not worth the money
As a teacher, I purchased for use in the classroom as it is difficult to project your voice when wearing PPE (i.e. mask, facesheild). Unless I had the mic almost touching my mouth, it would not project very loudly and (even though I charged the unit overnight every day) the length of the charge was very variable (sometimes it would last for the day, other times it would barely last an hour. After approx 5 months of (sporadic) use, it is now not working at all. Although this is a reasonably priced unit, the quality is very inconsistent and overall frustrating to use. In my opinion, this is not worth the money.
