4. Battery Charging and Power Saving
Your PI4 comes with the battery partially charged
may be used immediately. For best practice we
recommend to fully charge the headphones before
first use. Please allow up to 3 hours for full charge.
The headphones can be used while charging.
To charge:
1. Please use the supplied charging cable and
connect the USB-A plug to a wall charger or a
powered computer USB-A socket.
2. Then connect the USB-C end to the
headphones USB-C socket
Note: During charging, the headphone indicator
will flash green. When fully charged, the indicator
will remain illuminated. See Diagram 3 for status
indicator details.
4.1 Standby Power Saving
PI4 magnetic clip sensors intelligently conserve
power. When removed from your ears and clipped
together, PI4 will automatically enter Standby which
will pause media playback, disconnect Bluetooth,
and switch to a low power state.
When unclipped again, PI4 will wake and reconnect
to the last connected Bluetooth source. If the
magnetic sensors are disabled using the App, this
feature will also be disabled.
With the app, you can customise how long the
headphones will wait before switching to Auto
Standby, please see Standby Timer under Settings
in the App.
5. Wearing Your Headphones
Wearing your headphones correctly will help
ensure you get the best possible experience, see
Diagram 5. Like many in-ear headphones, the PI4
earpieces are designed to seal the ear canal in
order to perform optimally. The earpieces are also
designed be used with the stabiliser fins and must
be installed prior to use.
Both ear tips and stabiliser fins come in three sizes
(small, medium and large). Finding the proper size
for your ear is critical to obtaining a good seal and
ensure PI4 and the advanced features such as
Adaptive Noise Cancellation performs optimally.
1. Identify the left and right earpieces by finding
the identification legends located on the interior
of each cable near the earpieces. Hold PI4 by
the left and right control units and hang the
headphone around your neck comfortably, the
earpieces should be at equal length.
2. Place the earphones in your ear so that the
tips sit comfortably at the opening of the
ear canal.
3. Ensure the stabiliser fins are sitting comfortably
in the ear. Try another size if they do not fit.
Different sized ear tips and stabiliser fins can
be used to ensure the best possible fit.
