OPERATE YOUR HEADPHONES
Bluetooth Connection
Devices with Bluetooth 5.1 wireless technology-equipped computers, smartphones, and MP3 players.
To use Bluetooth for your audio connection, first pair CORE with your audio source (music player, smartphone, laptop, or another Bluetooth-equipped device that can act as an audio source). Make sure CORE is fully charged (without the audio cable plugged in) and turn it on by pressing and holding the Power button for 3 seconds. Once the power is turned on, CORE is in Bluetooth pairing mode. You can hear a voice notification – “Power on, pairing” and the LED indicator is blinking in red/blue quickly. Make sure Bluetooth is enabled on your audio source and in a few moments ‘MUVEACOUSTICS: CORE’ will appear on your list of possible Bluetooth connections. Press ‘pair’ or ‘connect’ on your device and after the connection is made, the LED indicator will turn to steady blue and you can hear “your device is connected”. Then your device is paired.
From now on, when you turn on CORE, it will automatically search for the last Bluetooth device it was paired with.
While there is no pairing with a Bluetooth device within 5 minutes, CORE will turn off automatically with a voice notification – “power off” and you need to switch it on again for further use.
Battery Charging
Please use the cable provided to recharge the headphones. It will take 2 hours to fully charge.
Wired Connection
CORE has a 3.5mm audio cable. If there is no Bluetooth source available or if you simply prefer a wired connection, you can connect your CORE directly to your audio source using a stereo male 3.5mm connector at the end of the cable.
CORE headphones come with an audio cable included. Control and talk functions vary depending on your phone, tablet, or application. The Bluetooth function will be shut off automatically when the audio cable is plugged in.
