Products of major brands that have passed the test of the authorities, are certified to be safe for health, avoid headaches, earaches because they have to listen to a lot of noise.

5. The louder the sound, the better the sound quality

The teaching assistant has the main function of amplifying the sound, so that the user does not need to speak loudly but still communicates clearly to the listener. But many users only pay attention to the "big" factor, not paying attention to "clarity".

This causes many people to choose a machine at the place of purchase, to see loud language, when used regularly, the machine is shrieking, hissing, uncomfortable for both listeners and speakers. So when buying a device, besides the loudness of the voice, pay attention to the sound quality.
