Wireless Voice Amplifier for Teachers, Original Voice Amplifier Wire Microphone with 2 Microphones, Portable Speaker megaphone for Classroom, Training, Meeting, Instructors, Coaches, Games

The exterior design is very delicate and compact, making it easy to carry, whether it's for classes, tour guides, or outdoor activities, it's very convenient.

The sound clarity on this device is terrific for the price. It also allows Bluetooth simultaneously with line in, as it says. However, it does not tell you that it auto-quiets the Bluetooth sound while line in is detected. This makes the Bluetooth sound "pop" back in once line in sound stops. This "pop" is often jarring depending on your volume level. There is no discernable way to make this stop nor instructions that accompany the device or online instructions.It's great for a hanging voice amp if that's all you want out of it. But if you plan to Bluetooth in background music while talking, when the music pops back in, it's jarring and loud and ruins the experience.

This mini amplifier is a very useful, beautiful appearance, and clear sound quality helper!

The sound quality of the mini amplifier is clear and the volume is large enough to effectively transmit sound even in larger spaces or outdoor environments.
