3. Setup
3.1 Eartip Selection and Installation
Proper eartip selection is crucial for optimal sound quality and noise isolation. The Pro X30 comes with 5 pairs of foam eartips and 5 pairs of silicone eartips in various sizes. Experiment with different sizes and materials to find the best fit for your ears.
- Gently remove the pre-installed eartips from the earphones.
- Select an eartip size and material that feels comfortable and creates a good seal in your ear canal.
- Carefully push the chosen eartip onto the nozzle of the earphone until it is securely attached.

3.2 Cable Connection
The Linum Bax T2™ cable features advanced MMCX connectors for a secure and reliable connection to the earphones.
- Identify the left (blue dot) and right (red dot) earphones and corresponding cable connectors.
- Align the MMCX connector on the cable with the receptacle on the earphone.
- Push the connector firmly into the earphone until you feel a click, indicating a secure connection.
- To disconnect, gently pull the cable connector straight out from the earphone. Avoid twisting or pulling on the cable itself.
4. Operating Instructions
4.1 Wearing the Earphones
The Pro X30 earphones are designed to be worn with the cable routed over and behind your ears for a secure and comfortable fit.
- Insert the earphone into your ear canal, ensuring a snug seal.
- Route the cable over the top of your ear and behind it. The moldable wire allows for adjustment to fit the contour of your ear.
- Adjust the cable length using the slider to ensure a comfortable and secure fit around your neck or back.

4.2 Connecting to an Audio Source
Connect the 3.5mm jack of the Linum Bax T2™ cable to your audio device (e.g., monitor pack, mixer, smartphone, tablet, or computer). Ensure the connection is firm to prevent signal loss.
Note: While the product specifications mention 'Bluetooth' under Wireless Communication Technology, the included cable is wired. For Bluetooth functionality, a separate Bluetooth-enabled MMCX cable (not included) would be required. This manual focuses on the wired operation with the included Linum Bax T2™ cable.
4.3 Volume Control
Adjust the volume directly from your audio source or monitoring device. The Pro X30 earphones do not feature in-line volume controls on the standard Linum Bax T2™ cable.
5. Maintenance
5.1 Cleaning the Earphones and Eartips
- Regularly clean your earphones and eartips to maintain hygiene and optimal sound performance.
- Gently wipe the exterior of the earphones with a soft, dry cloth.
- Remove eartips and clean them with mild soap and water. Ensure they are completely dry before reattaching.
- Use the included cleaning tool to carefully remove any earwax or debris from the earphone nozzles.
5.2 Storage
When not in use, store your Pro X30 earphones in the provided Impact Resistant Monitor Vault to protect them from damage and environmental elements.

6. Troubleshooting
6.1 No Sound or Intermittent Audio
- Check Connections: Ensure the cable is securely connected to both the earphones (MMCX) and the audio source (3.5mm jack).
- Test Audio Source: Verify that your audio source is functioning correctly by testing it with another pair of headphones.
- Inspect Cable: Check the cable for any visible damage or kinks. If damaged, consider replacing it with a genuine Westone Audio Linum Bax T2™ cable.
- Clean Nozzles: Earwax buildup can block sound. Use the cleaning tool to clear any obstructions from the earphone nozzles.
6.2 Poor Fit or Discomfort
- Try Different Eartips: Experiment with all included foam and silicone eartips to find the size and material that provides the most comfortable and secure seal for your ear canals.
- Adjust Cable Over-Ear: Ensure the cable is properly molded over and behind your ear to distribute weight and maintain position.
6.3 Unbalanced Sound
- Check Left/Right: Ensure the correct earphone is in the correct ear (left in left, right in right).
- Clean Both Earphones: Ensure both earphone nozzles are free from debris.
- Test Cable: If possible, test with a different cable to rule out a faulty connection or cable issue.
