ADJUSTING SIDETONE
Sidetone lets you hear your own voice during
conversations so you are aware of how loud
you are talking. In Logi Tune, select the sidetone
feature, and adjust the dial accordingly.
– A higher number means you hear more
external sound.
– A lower number means you hear less
external sound.
AUTO SLEEP TIMER
By default, your headphones will automatically
power off when not in use for 30 minutes.
Adjust the sleep timer in Logi Tune. To wake up
your headphones, try sliding off/on the power
switch again.

button for 5 seconds.

to white for 3 times and then turns off when
