Product introduction: BA300s uses two micro-tubes to amplify, current-mode operational amplifiers with extended output and 4.4mm balanced input and output. Superior power management ensures the performance of the whole machine. The machine does not set the volume control. The gain of the whole machine is +3dB, which improves the output amplitude of most front ends. The signal is amplified by the micro-tubes, and the output is rich, satisfying the different sound experience of the user. Built-in lithium polymer rechargeable battery, charging for 3 hours, battery life for 7 hours.
