    • Good for regular classrooms
Color: Black 2 Mics
I do fitness classes and purchased this to see if it would work during class. It was OK. I needed it to be louder with the background music, but i can see it be worth it for a regular classroom. the sound quality was good, and it looks durable, but it just wasnt a right fit for my fitness class.

    • Can you hear me now
Color: Black 1 Mic
I teach state mandated programs in high school. Works well. I use it to present in school auditoriums when they don't have an audio system. The pairing and channels selection was not that obvious but trial and error worked.

    • Range is only about 10 feet.
Color: Black 2 Mics
Microphone heads are magnetic and have a strong hold when they're on. Even when shook aggressively they stay on. You don't have to put your mouth on them to get sound to go through. They pick up audio well. What's even better is that they don't pick up sounds: clicking, humming, chewing, etc. Only clear audio. The speaker box will automatically connect to the microphones without doing anything to it. You can use both microphones at once. It's not like a walkie talkie where you have to take turns talking. The box gets loud. It has some serious power, I'm impressed. The only downside I see is the range. I got about 10 feet away from the box and it lost connection. You can't leave the box in the garage and call out that dinner's ready from the kitchen. It has to be in super close proximity. You don't really need to amplify your voice 10 feet from someone so for me it's not worth the money. I have no use for it. ... show more
