MULTIPOINT CONNECTION
The TREBLAB Z7 Pro headphones have a multipoint connec-
tion. It allows two devices to be connected at the same time.
While you won't receive the input from both devices at the
same time, you'll be able to switch from one device to another
seamlessly.
To connect the Z7 Pro to the second device:
Switch off temporarily the wireless mode on the first device
the headphones are connected to.
Repeat pairing steps 2-6 to connect the second device.
Turn on the Bluetooth mode back for the first device and
connect the Z7 Pro again.
When you turn the headphones on, they will try to reconnect
to the recently connected device/devices. If the reconnection
does not happen automatically, the headphones will try to find
the next device in the pairing list. The headphones can save
the last 8 devices.
ANC/AMBIENT SOUND MODES
The TREBLAB Z7 Pro headphones feature Hybrid Active Noise
Cancellation technology. This technology provides the ability
not only to decrease the surrounding noise in the ANC mode

but also to amplify some frequencies in the Ambient Sound
mode to hear voices when using the Z7 Pro headphones.
When the Z7 Pro are turned on, the ANC mode is enabled
automatically. In the ANC mode the green LED on the right
earcup is lit up. To switch to the Ambient Sound mode, press

To disable both ANC and Ambient Sound modes, press the
ANC button once again. You will hear the “Ambient sound and
noise cancelling off” voice prompt and the white LED light on
the right earcup will go off.

Keep the dedicated ANC microphone holes on both earcups
unblocked when using the ANC/Ambient Sound functions.
AWARENESS MODE
When you listen to music and some person approaches you to
talk, you can fastly lower the music volume to the minimum and
activate the Ambient Sound feature to keep the conversation
going. To do so, cover the right earcup with a palm. Once you re-
lease the earcup, the music will go back to the previous volume
level and the Ambient Sound feature will be disabled.

CHARGING AND BATTERY
One full battery charge provides up to 45 hours of playtime
with ANC disabled and up to 30 hours with the ANC function
activated. To check the current battery level, press the POWER
button when the headphones are turned on. You will hear the
voice prompt saying the current percentage of the battery left.
When the battery is running low, you will hear the “Battery Low”
voice prompt. To charge the headphones, plug the supplied
charging cable into the Type-C charging port on the left earcup
and the other end of the charging cord into a standard USB
port. The LED light will turn RED. It takes up to 2.5 hours to fully
charge the Z7 Pro. The RED light will turn GREEN when the
headphones are fully charged.
Be sure to use a 5V DC, 1A adapter or charger. Using a power
source with lower power will increase the overall charging time.
Unplug Z7 Pro from the charging cable and the cable from the
power source when not in use. If left unused, a fully charged
battery will lose its charge over time. We recommend charging
TREBLAB Z7 Pro fully at least twice a month to maintain the
sufficient battery life.
