Auto power off
To optimise battery life, your headphones turn off automatically after 5 minutes in Bluetooth search mode, if not
synchronised with any other device.
Charging the battery
When the battery level is below 10%, the LED indicator (6) starts flashing red. When the battery level is below 2%, you
will hear a sound to remind you to charge it.
The LED indicator (6) lights up red while charging the device and turns off once the charging process is complete. To
charge the battery, plug the USB Type-C end of the provided USB cable to your headphones' USB Type-C charging port
(7) and the other USB end to any device with a USB charging port that provides energy (PC, USB wall charger, car
charger, etc.). It takes approximately 2 hours to charge it.
Note:
To optimise battery life, do not store or leave your device unused or completely discharged for a long period of
time.
The headphones will power off and start charging when you connect the charging cable. Current EU safety
regulations do not allow to charge and use the headphones at the same time.
Caution: Do not charge your headphones with fast charging adapters or dedicated laptop charging adapters, Because
their output voltage exceeds 5V and the device may become unusable.
Wireless Bluetooth® connection
Press and hold the Multifunction button (2) for 2 seconds, until the LED indicator (6) starts flashing white. Your
headphones are now ready to be paired with your Bluetooth device. Select Headphones Bluetooth® Style 3 on your
device screen and press "connect". You will hear a confirmation sound when both devices are paired.
Once your devices are synchronised, you can control basic playback functions such as turning up and down the volume
and switching to the next or previous track directly from your headphones.
Press Volume + (1) or Volume - (3) to turn up or down the volume. You will hear a sound when reaching the maximum
volume level.
Press and hold Next (1) to skip to the next song. You can also press and hold Back (3) to skip to the previous track.
Press the Multifunction button (2) once to pause or resume playback.
Note: If you're using the audio cable instead of the Bluetooth connection, you will have to control music playback from
your music player and not from the headphones.
Call control (hands-free function)
Once your headphones and smartphone are paired using the Bluetooth® connection, simply wear your headphones and
answer calls with the Hands-free microphone (8).
Press the Multifunction button (2) to answer an incoming call. If you are listening to music when you receive a call,
playback will pause and you will hear an incoming call sound. You can also press and hold this button for 2 seconds to
reject a call.
Press the Multifunction button (2) to hang up. Playback will resume from where it stopped.
The built-in microphone is designed to answer conventional phone calls from the smartphone. If you intend to connect
these headphones to your Windows PC or MAC and use them for home office purposes such as video calls (Teams,

Skype, Zoom, etc.), we recommend purchasing this add-on specifically designed for optimal performance:

Voice Assistant
Your Headphones Bluetooth® Style 3 feature a Voice assistant button (4) that allows you to directly activate your
smartphone's assistant.
This function activates your smartphone's digital assistant and lets you use voice commands to perform tasks naturally
and easily.
Please take into account that the Voice assistant button (4) activates your smartphone's voice assistant and depends on
it to perform actions. You can also take a look at Google Assistant and Siri user guides, available on their manufacturers'
websites.
Audio input
You can also connect your Headphones Bluetooth Style 3 to your music player using the audio cable provided. You don't
need to switch on your headphones if you want to use the audio cable.
To enable this mode, simply plug one cable end into the Audio input (5) and the other end to your music player.
Note: If you're using the audio cable instead of the Bluetooth wireless connection, you will have to control music
playback from your music player and not from the headphones.
Reset
You can force your Headphones Bluetooth® Style 3 to shut down. To do so, press and hold both the Volume + (1) and
Volume - (3) buttons. The headphones will disconnect from the last paired device.
