I use to be a Substitute gym teacher and this device is indeed ... loud. Works wonderfully inside the gym and classrooms. This device does win 5 stars BUT! My only complaint (or recommendation) is how the ON and OFF works on this device. It should be a button, not the way that it is. If they can fix that one day, this would be 10 out of 10. Still 5 stars overall.

Greetings Anyone who is on a journey with Throat Cancer! After radiation therapy and healing , your voice control is very quiet. This Voice enhancer is very portable and provides speech sound and quality with the patient. After oncologist visit , the speech therapist covered this option for voice therapy. Regards

Ottimo, bisogna provarlo un po prima di abituarsi e saperlo usare nel modo più corretto. È comunque semplice.

Werkt goed. 4 sterren omdat ik deze wel iets minder goed vind als mijn oude, precies dezelfde van dit merk. Maar tot nu toe heeft deze het beste geluid voor een spraakversterker die ik dagelijks gebruik.
