Review: Great sound and capabilities - Very pleased with all of the possible amplification options. Bluetooth paired easily with phone and computer - good range, tried it between rooms, perhaps 30 feet. When I cycled inputs on amp, it quickly reconnected automatically to phone. Mic/headset and all features listed work well. Operation is simple - a single button cycles through different inputs. I am impressed with the FM receiver - as good or better than some of my other small portable radios. Any use of a mic and amp can cause feedback - so start with low volume and position amp and mic for best results, slowly raise volume to suit needs.
Review: Works great for school - As an elementary school librarian who teachers lessons to every class in the school, every week, having to wear a mask, I was concerned about my voice. I purchased this at the beginning of the school year and have used it for six months now. It stays charged for around a week or so. It allows the students to hear me clearly and I can hear myself so I do not strain my voice even when I have two masks on. Once you get over the feeling of working in a theme park, it is truly helpful! Many of the other teachers in my building have bought them as well.
