The sound quality of this amplifier board is quite clear, with a very comfortable and pleasant vocal sound. The output is also awesome, producing good effects when used with 2-4 speakers. It can be powered by a mobile phone charger or a computer USB port, which is very convenient. We recommend using a 5V 2A TYPE-C interface. The board material is very luxurious, consumes very little power, and generates little heat, making it suitable for long-term use.
