Wearing the Earbud
Insert the earbud into one ear canal. The ergonomic design is intended to provide a secure and comfortable fit. The cable clip can be used to secure the cable to your clothing, reducing cable movement and ensuring the microphone stays in an optimal position for clear voice pickup.

Ear Tip Selection and Replacement
Optimal sound quality and comfort depend on selecting the correct ear tip size. The J6MS comes with several sizes and styles of silicone ear tips to ensure a custom fit.
- Selection: Experiment with different sizes to find the one that creates a good seal in your ear canal without causing discomfort. A good seal enhances bass response and noise isolation.
- Replacement: Gently pull off the existing ear tip from the earbud nozzle. Align the new ear tip with the nozzle and push it on firmly until it is securely attached.

Compatibility
The JLab J6MS is compatible with most devices featuring a standard 3.5mm headphone jack, including:
- Smartphones (Android, iPhone, Motorola, Palm, HTC, Windows, BlackBerry)
- Tablets
- Laptops and Personal Computers
- 2-way radios and other communication devices
Note: For modern smartphones without a 3.5mm jack, a USB-C to 3.5mm adapter (not included) may be required.
Maintenance
- Cleaning Ear Tips: Regularly remove ear tips and clean them with a soft, damp cloth. Ensure they are completely dry before reattaching.
- Cleaning Earbud Nozzle: Gently wipe the earbud nozzle with a dry cotton swab to remove any earwax or debris. Avoid using liquids directly on the earbud.
- Cable Care: Avoid sharp bends or excessive pulling on the cable to prevent internal damage. Store the earbud neatly coiled when not in use.
Troubleshooting
- No Sound:
- Ensure the 3.5mm jack is fully inserted into the device's port.
- Check the volume level on your device.
- Test the earbud with another device to rule out device-specific issues.
- Microphone Not Working:
- Ensure the 3.5mm jack is fully inserted. Some devices require a TRRS (4-pole) jack for microphone functionality, which the J6MS provides.
- Check your device's audio input settings to ensure the external microphone is selected.
- Ensure the microphone is not obstructed.
- Poor Sound Quality:
- Verify that the ear tip is correctly sized and forms a good seal in your ear.
- Clean the earbud nozzle and ear tips as described in the 'Maintenance' section.
