We have launched an economical series of voice amplifier that will fit all schools' budget. Not only its rechargeable, the weight is greatly reduced to less than 160g while the maximum output is now 10 watts. KEC has kept its quality consistent and we use the best material to build our product. With schools and teachers' support for the past 15 years, these have encouraged us to keep making new products. Thus, we present KEC VA900 Voice Amplifier, the 2020 model to fight Covid situation.
