6. Bluetooth Connection
6.1 Pairing
PI4 is designed to stream media wirelessly from
Bluetooth audio devices, such as smartphones,
tablets or personal computers. To do so, the
headphone and device (source) must first be paired,
see Diagram 6.
1. The first time you switch on your headphones,
Bluetooth pairing mode will be enabled,
the indicator will flash blue. If pairing mode
is not enabled, press and hold the power
button for 5 seconds, let go when the
indicator blinks blue and when an audible cue
is presented.
2. Ensure the Bluetooth feature is enabled on the
audio device, PI4 will appear in the discovery
list, select it to pair.
3. The indicator will flash blue while pairing is
in progress, this will change to solid blue
and an audible cue presented when pairing
is successful.
Your headphones will remember up to eight paired
Bluetooth devices. Repeat the above steps to pair
more devices.
Note: Your headphones will automatically exit
Bluetooth pairing mode if no device is paired
within 5 minutes. If pairing fails, the indicator will
rapid flash blue, please try pairing again.
6.2 Multiple Bluetooth Connections
PI4 can connect up to two devices at the same time,
but note that you can only play audio or take calls
from one device at a time.
To switch between two devices:
1. Pause audio on the first device, or use the
PI4 multi-function button.
2. Play audio from the second device and the
headphone will switch over.
When streaming audio, receiving a call on the
second device will automatically pause playback
and the call will be routed automatically to your
headphones. Ending the call will automatically
resume playback from the first device.
