U606 Pro has the following practical enhancements:
1 - low battery indicator - low power indicator 0.5S power indicator - personalized reminder.
2 - delay 2 seconds to connect the headphone output (make the power supply of the circuit stable before connecting the headphone output, to avoid crashing the headset at power-on).
3 - With earphone protection, when the circuit is faulty, the earphone protects the work, cuts off the output of the earphone and the power indicator light blinks 0.2S - fault reminder.
4 - Full symmetrical amplifier power supply circuit - can provide positive and negative power supply for large current, increase signal bandwidth and dynamic response, support computer and other colleagues to input audio and USB charging (no longer virtual power supply circuit).
5 - The power efficiency of the new scheme is further enhanced (life time: >9 hours (normally: 9-12 hours) depending on the time of use).
6 - with IC socket, can exchange other opamp very easy, high playability
