can work directly without a driver.
Operation guide: hold the button⑦and meanwhile insert the USB cable which
is already connected to a computer into the Q3. After connecting, release the
button⑦and select the Q3 as the output device on the computer. (Note that the
driver-free function is only available for systems of Windows7, 8 and 10,
excluding the Windows xp system.)
2) If the Windows system supports UAC2.0: when first connecting the Q3 to the
computer, please go to our website to download the USB DAC driver and
follow the corresponding instructions to install it.

3) For MAC computers: there is no need to install the USB DAC driver, so
directly select the Q3 as the output device.
Notes: it is recommended to set the system output volume on the computer to the
max level and then adjust the output volume of the Q3 with its volume knob.
4) When using the included Lightning to Type C cable to connect the Q3 to your
iPhone/iPad/iPod, you could better enjoy your Hi-Res music.
5 Line in (headphone amp mode)

When not connecting to the computer, turn on the Q3 and insert the line-in
audio cable into the Q3’s line-in port (3.5mm headphone output port), and
meanwhile insert the balanced headphones into its 2.5mm or 4.4mm headphone
output port. In this way, the Q3 will enter headphone amp mode which can
amplify input signals and output them through balanced headphones. If it is
connected to a computer, first you need to stop the playback on the computer to
enable the Q3’s headphone amp function. If the computer is playing audio, the
Q3 will give priority to the USB DAC function.
6 Other functions
1) Standby mode
If the Q3 is not being charged or working, it will enter standby mode
automatically after 5 minutes to help to save more power with all indicator
lights off. To wake up the Q3, you need to turn it off and then turn it on, or
connect it to a USB device.
2) Charging switch
If the Charging switch is set to ON, the Q3 will be charged once it is connected
to a USB device (except in low battery state). If the Charging switch is set to
OFF, the Q3 will not be charged. If Q3 runs out of battery, it will be charged
regardless of the charging switch state until it is fully charged. When the Q3 is
connected to a mobile device, it is suggested to set its charging switch to OFF to
save the battery power of the mobile device.
3) How to use the Type C to Type C USB cable

When using the included Type C to Type C USB cable to connect the Q3 to a
mobile device, please follow the direction of the arrow on the cable end. The
