Using the “K2” function

The “K2” function offers high-quality audio by restoring transmitted compressed sound origins to high-resolution audio.

When the unit is connected to a BLUETOOTH device and the earphones are worn, tapping the touch sensor area on the R earphone 4 times quickly toggles on/off the “K2” function.
