Operation Guide

How to Ensure a Proper Fit

Using appropriate size ear-tips is critical to isolate external noise and achieve a snug, secure fit. Try on one ear-tip at a time to find the best fit for each ear. Gently push the earbuds into your ears and adjust the headset until it fits comfortably. You should notice a drop in ambient noise when the ear-tip has been placed correctly.

To Change the Silicone Ear-tips

1. Turn over the upper cover on the ear-tip.

2. Rotate and firmly push the ear-tip tube to cover the ear-tip pillar.

3. Turn the upper cover of the ear-tip back on the nozzle.

Charging

Important Considerations:

• The X3-Pro's case is not compatible with 90W+ chargers.
• The X3-Pro model comes with a protective film on the charging pins of the charging case. Remove this film prior to charging the earbuds.
• After use and before charging, wipe the earbuds carefully to remove any moisture from the charging contacts.

To charge the case

You can check the current charging case battery level by looking at the indicator on the front of the charging case. We recommend charging the case when the battery level reaches 10%. Connect one side of the supplied charging cable into the Type-C charging port and the other side into a power source, or place the case onto a wireless charger. While charging, one digit on the indicator will flash slowly. Once fully charged, all digits will be steady. It takes about 3 hours to fully charge the case. Use a 5V DC/0.5-1A adapter or charger.

To charge the earbuds with the charging case

When the earbuds' battery is running low, you will hear a sound prompt. Put the left and right earbuds into the slots in the charging case. The earbuds will turn off automatically and start charging. The white state indicators on the earbuds will show the charging status. When fully charged, the white state indicator will go off. It takes about 2 hours to charge the earbuds.

Power Bank Mode

The TREBLAB X3-Pro charging case can be used as a power bank to charge your smartphone or tablet. Connect your device to the charging case by plugging your device's charging cable into the USB Type-A power bank port. The case battery level indicator will light up for 10 seconds. NOTE: There is no indication signal when the smart device is fully charged. Please pay attention to your device's battery indicator.

Setting Up Your TREBLAB X3-Pro

To turn the earbuds on

1. Take the earbuds out of the case; they will turn on automatically.

2. Alternatively, touch the Touch panels of both earbuds and hold for 2 seconds. You will hear sound prompts indicating they are on and ready for pairing. The blue state indicator will light up on both earbuds, and a few seconds later, the state indicator will start flashing blue/white on one of the earbuds.

3. You will hear another sound prompt after connecting to the device.

To turn the earbuds off

1. Put both earbuds into the slots in the charging case.

2. Alternatively, touch the Touch panels of both earbuds and hold for 4 seconds when no media is played. You will hear a sound prompt indicating they are turning off. The white state indicator will light up for 1 second and go off on both earbuds.

Pairing

You can pair the X3-Pro earbuds with your device either together or separately. Using only one earbud at a time can extend the overall playtime.

To pair both earbuds

1. Open the case lid and take the earbuds out. The blue state indicator will light up on both earbuds, and a few seconds later, the state indicator will start flashing blue/white on one of the earbuds.

2. Activate the wireless communication function on your smart device, scan/search for TREBLAB X3-Pro, and click CONNECT.

3. If prompted by your device to connect, select Yes.

4. You will hear a sound prompt indicating that the earbuds are connected. The state indicator will start blinking white every 15 seconds.

When you turn the earbuds on, they will try to reconnect with the recently connected device. If reconnection does not happen automatically, the earbuds 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 devices.

NOTE: The earbud with the flashing blue/white state indicator is the main one. For better performance, keep your smart device closer to the main earbud.

To pair one earbud only

1. Take one earbud out from the charging case. The state indicator should start flashing blue/white, indicating it is in pairing mode.

2. Activate the wireless communication function on your smart device, scan/search for TREBLAB X3-Pro, and click CONNECT.

3. If prompted by your device to connect, select Yes.

4. You will hear a sound prompt indicating that the earbuds are connected. The state indicator will start blinking white every 15 seconds.

Audio Playback

To pause and resume playback, double-touch either earbud's Touch panel.

To change tracks, triple-touch the right earbud's Touch panel for the next track and triple-touch the left earbud's Touch panel for the previous track.

To adjust the volume, touch the right earbud's Touch panel once to increase volume and touch the left earbud's Touch panel once to decrease volume.

Phone Calls Management

The TREBLAB X3-Pro can be used to make and receive calls wirelessly. Audio playback will be paused during calls.

Gaming Mode

TREBLAB X3-Pro earbuds support gaming mode to reduce audio latency up to 60 ms, improving video/audio synchronization for gaming and video-watching.

1. To enable gaming mode, touch the left earbud's Touch panel four times. You will hear an ascending sound prompt and feel lower latency.

2. To disable gaming mode, touch the left earbud's Touch panel four times again. You will hear a descending sound prompt, and the latency will return to the standard 200 ms.

NOTE: In gaming mode, the connection range is shorter. If you experience connection issues or drops, disable gaming mode.

Voice Assistants Support

TREBLAB X3-Pro earphones are compatible with most voice assistants. To use the voice assistant, touch either earbud's Touch panel and hold for 1 second.

Reset to the Factory Settings

You can reset the X3-Pro earbuds to factory default settings by cleaning up the pairing list. Make sure the earbuds are disconnected from the source device. Tap five times on both earbuds' Touch panel. The red state indicator will light up on both earbuds, and they will turn off automatically. The earbuds' memory is returned to factory settings.

Cleaning

It is recommended to clean the earbuds once every two weeks as earwax can accumulate and clog the protective screen or ear-tip opening.

To clean the earbuds, you will need:

• Cotton swab
• Eyelash brush or alike
• Alcohol

1. Take off the silicone ear-tip.

2. Soak the cotton swab in alcohol and clean the ear-tip opening.

3. Repeat for the other eartip.

4. Soak the eyelash brush (or alike) in alcohol.

5. Clean the protective screen on the nozzle with forward and backward movement.

6. Repeat the procedure for the other earbud's nozzle.

7. Let the ear-tips and nozzles dry before putting the ear-tips back on.
