CHARGING AND BATTERY
To charge the headphones, plug in the supplied charging cable into
the Micro-USB charging port on the right headphone, and the other
end of the cable into a standard USB port. The LED light will turn
RED. Z2 takes up to 4 hours to fully charge. The RED light will turn
OFF when the headphones are fully charged.
One full battery charge provides up to 25 hours of playtime at
maximum volume, and up to 30 hours at medium volume. When the
battery is running low, you will hear a “Battery low” voice prompt.
To maximize the battery lifespan charge your headphones through a
low voltage power source such as a computer’s USB port. If you’re
using an AC/DC adaptor or charger, be sure to use a 5V, 1A rated
USB charger and the supplied charging cable.
Unplug the Z2 from the charging cable and the cable itself from the
power source when not in use.
If left unused, a fully charged battery will lose its charge over time.
We recommend fully charging the Z2 twice a month to ensure
sufficient battery life.

this may cause the headphones to malfunction or become
