Earbud Functions and Operations

How to Ensure a Proper Fit

To get the best possible fit with your X-Open earbuds, put the earbuds onto your ears and twist the earphone bodies towards the earhooks until the earbuds are firmly secured. With a proper fit, you'll notice more range when listening to music.

Charging

There are three important points to keep in mind regarding charging:

• The X-Open's case is not compatible with 90W+ chargers.
• The X-Open model comes with protective stickers on the charging contacts of each earbud. Remove these stickers 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 charging case battery indicator on the front of the charging case when putting the earbuds to charge:

• <5%: Red LED flashes for 10 seconds.
• 6-33%: Red LED stays on for 10 seconds.
• 34-70%: Orange LED stays on for 10 seconds.
• 71-100%: Green LED stays on for 10 seconds.

It is recommended to charge the case when the battery level reaches about 10%.

To charge the case, connect one side of the supplied charging cable into the Type-C charging port (on the back of the case) and the other side into the power source, or simply put the case onto a wireless charger. While charging, the LED battery indicator of the corresponding color (see above) will show the current battery level. Once fully charged, you will see the green LED flashing. It takes about 2 hours to fully charge the case using a wire or a wireless charger.

Be sure to use a 5V DC, 0.5 - 1A adapter or charger. Using a power source with lower power will increase the overall charge time.

To Charge the Earbuds with the Charging Case

When the earbuds' battery is running low, you will hear a sound prompt (similar to a busy tone).

Put the left and right earbuds into the slots in the charging case. The earbuds will turn off automatically. The case will immediately start charging the earbuds. You will see the white state indicators on the earbuds. When the earbuds are fully charged, the white state indicator will go off. It takes about 2 hours to charge the earbuds.

Setting Up Your TREBLAB X-Open

To Turn the Earbuds On

1. Take the earbuds out of the case; the earbuds will turn on automatically.
2. Alternatively, touch the Touch panels of both earbuds and hold for 2 seconds. You will hear several sound prompts indicating that the earbuds are turned on and ready for pairing. The white state indicator will light up on both earbuds and, a few seconds later, the state indicator will start flashing 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 there is no media played. You will hear the sound prompt indicating that the earbuds are being turned off. The white state indicator will light up for 1 second and go off on both earbuds.

Pairing

You can pair the X-Open earbuds with your device either together or separately. Using only one earbud at a time can help extend the overall playtime. Please read the instructions below to make the pairing process smooth and easy.

To Pair Both Earbuds

1. Open the case lid and take the earbuds out of the case. The white state indicator will light up on both earbuds and, a few seconds later, the state indicator will start flashing white on one of the earbuds.
2. Activate the wireless communication function on your smart device, scan/search for TREBLAB X-Open, and click CONNECT.
3. If prompted by your device to connect, select Yes.
4. You will hear the 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 the 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 in the pairing list.

NOTE: The earbud, which state indicator is flashing white during the pairing, is the main one. For better performance, keep your smart device closer to the main earbud.

To Pair a Single Earbud

1. Take one earbud out from the charging case. The state indicator should start flashing white, indicating that it is in the pairing mode.
2. Activate the wireless communication function on your smart device, scan/search for TREBLAB X-Open, and click CONNECT.
3. If prompted by your device to connect, select Yes.
4. You will hear the sound prompt indicating that the earbuds are connected. The state indicator will start blinking white every 15 seconds.

Audio Playback

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

To change tracks on X-Open, triple-touch the right earbud's Touch panel to play the next track and triple-touch the left earbud's Touch panel to play the previous track.

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

Phone Calls Management

The TREBLAB X-Open can be used to make and receive calls when connected wirelessly. Audio playback will be paused during the calls.

Gaming Mode

TREBLAB X-Open earbuds support the gaming mode to reduce the audio latency up to 60ms. This allows to achieve better video/audio synchronization and improve your gaming and video watching experience.

1. To enable the gaming mode, touch the Touch panel four times on the left earbud. You will hear the ascending sound prompt and feel the lower latency while gaming/watching videos.
2. To disable the gaming mode, touch the Touch panel four times on the left earbud again. You will hear the descending sound prompt and the latency will go back to the standard 200ms.

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

Voice Assistants Support

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

Reset to the Factory Settings

You can reset the X-Open earbuds to the factory default settings by clearing up the pairing list with the last 6 connected to X-Open devices.

Make sure that 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 the earbuds will turn off automatically. The earbuds' memory is returned to the factory settings now.

Cleaning

It is recommended to clean the earbuds once every two weeks as dust can accumulate and clog the speaker protective screens located on the side and on the bottom of the earbuds.

To clean the earbuds, you will need:

• Eyelash brush or alike
• Alcohol

1. Soak the eyelash brush (or alike) into the alcohol.
2. Clean the protective screens on the side and bottom of the earbuds with forward and backward movement.
3. Let the earbuds dry before repeated use.

Troubleshooting

Safety Rules

• Never disassemble or modify your X-Open for any reason. Doing this may cause the device to malfunction or even become combustible. The damage to your device can void your manufacturer's warranty.
• Do not charge the earbuds when they are wet. Make sure to dry off the earbuds before charging.
• Avoid exposing the TREBLAB X-Open to extreme temperatures (below 37F/3C or above 112°F / 45°C). Extreme temperatures can deform the components inside the X-Open, reducing the battery life and the lifespan of your new earbuds.
• Avoid putting the device's LED lights close to the eyes of children or animals.
• Do not use your X-Open during a thunderstorm. Thunderstorms could cause them to seriously malfunction and increase the risk of electric shock.

Battery Information

• Your device is powered by rechargeable batteries.
• Unplug the charging case from the electrical plug when not in use.
• If left unused, a fully charged battery will lose its charge over time.
• It is recommended that you fully charge your earbuds twice a month to ensure the battery's integrity.
• Please do not leave the device (and the charging case) in hot or cold places, such as inside a closed car in the summer or winter, as this will reduce the capacity and life of the batteries.
• Do not expose the batteries to fire as they may explode.
• Batteries may also explode if damaged.
