- 4.4mm balanced input and output, current-mode operational amplifier diffused output, using 2 micro-tubes to amplify
- Charging for 3 hours, battery life for about 7 hours, built-in lithium polymer rechargeable battery.
- This unit does not set the volume control, the overall gain +3DB, to improve the output amplitude of most front ends.
- Superior battery management ensures overall performance.
- The signal is amplified by the bile duct, which satisfies the user's different sound experience.
