S515 10 Watts Portable Loudspeaker
This vocal amplifier is ideally suitable for any school teacher, as they often need to teach many students in a big room, so it is important that the pupil in the last row can hear you clearly without having to strain their ears.
Moreover, it saves you from the hassle of yelling or shouting out what you wish to say – to put it in a nutshell, you can get through the day without suffering from hoarseness or a sore throat.
