Setting

To turn on the headphones

To turn off the headphones

Set the POWER switch to the OFF position. You will hear the sound prompt, the state indicator will flash red several times, and it will go off.

Pairing

Make sure that the TREBLAB C7-Pro headphones are charged.

1. Set the POWER switch to the ON position. You will hear two sound prompts, the state indicator on the headphones will start flashing blue, and, a few seconds later, blue/red.
2. Activate the wireless communication function on your smart device, scan/search for TREBLAB C7-Pro, and click CONNECT. If prompted by your device to connect, select Yes.
3. You will hear the sound prompt indicating that the headphones are connected. The state indicator will go off. When you turn the headphones on, they will try to reconnect with the recently connected device.

If the reconnection does not happen automatically, the headphones will try to find the next device in the pairing list. You can only connect and play audio from one device at a time. But you can save up to 6 connected.

Gaming Mode

TREBLAB C7-Pro headphones support the gaming mode to reduce the audio latency up to 60ms. This allows you to achieve better video/audio synchronisation and improve your gaming and video-watching experience.

1. To enable the gaming mode, triple-press the MFB. You will hear the ascending sound prompt and feel the lower latency while gaming/watching videos.
2. To disable the gaming mode, triple-press the MFB again. You will hear the descending sound prompt, and the latency will go back to the standard 200ms.

In the gaming mode, the connection range is much shorter than in standard mode, so if you are experiencing some connection issues or drops, please make sure to disable the gaming mode.

Charging

When the headphones’ battery is running low, you will hear the sound prompt reminding a busy tone. To charge the C7-Pro headphones, you have two options:

1. Plug the supplied cable into the Type-C charging port on the back of the supplied charging stand and the other end of the charging cord into a standard USB port.
2. The blue state indicator will light up on the charging stand. Put the headphones onto the charging stand, and match the contacts on the left earcup with the pins on the charging stand.
3. When put correctly, the red state indicator will light up on the stand. Plug the supplied cable into the Type-C charging port on the left ear cup and the other end of the charging cord into a standard USB port. The state indicator will turn red.

It takes up to 2.5 hours to charge C7-Pro. When the headphones are charged, the red light will turn blue (either on the stand or on the headphones) for 10 seconds and will go off.

• Clean the charging contacts on the headphones and the charging stand with a slightly damp cotton swab when the headphones are turned off, and the stand is unplugged (we recommend using alcohol or a specially designed cleaning fluid for electronics).
• Make sure the C7-Pro headphones are not paired with any other device, as they can pair only with one device at a time. If C7-Pro is in pairing mode and flashes blue/red, but is still not found by your device, please restart your device and the headset.
• Reset your headphones to the factory settings by following the steps from the section “RESET TO THE FACTORY SETTINGS”. Try to pair again. Make sure that the distance between your device and the headphones is less than 33 feet / 10 meters. Make sure that nothing is blocking the signal between your device and your C7-Pro headphones.
• If the headphones are on but disconnected from the device for longer than 15 minutes, they will turn off automatically to save power. Make sure your laptop supports a ireless connection. If it doesn’t, you will need an external wireless USB  adapter compatible with your laptop. For further details, consult with your laptop manufacturer.
