The headphone amp section has normal and desktop power modes. The Patented Desktop Mode can be turned on when a second usb-c cable is attached as a power supply. QX11 will pull power from the second usb source to run the headphone amp and can achieve much higher power output, up to 800mW from the 4.4mm balanced output!

QX11 amp section is comprised of an end to end matching suite of chips from Texas Instruments, low power consumption, stable high output, low distortion and incredible dynamics. The configuration is dual Ti OPA1692 voltage chips + quad Ti OPA1622 headphone amp chips.
A handy feature to extend listening times, the second usb-c port can also be used as a PD Power charging pass through, with up to 45 watts of charging power passed on to your phone so you can charge while you listen, instead of just running down your battery!
