3. Installation Instructions

Follow these steps to replace the ear cushions on your Boltune BT-BH010 Headphones.

1. Remove Old Ear Pads: Gently peel off the existing ear pads from your headphones. They are typically held in place by a thin rim or adhesive.
2. Identify Plastic Ring: Locate the plastic mounting ring on the headphone's ear cup. This ring secures the ear pad.
3. Detach Plastic Ring (if necessary): In some cases, the plastic ring may need to be carefully pried or unclipped from the headphone to facilitate installation. Use a small, non-abrasive tool if needed, exercising caution to avoid damage.
4. Position New Ear Pad: Align the new ear cushion with the headphone's ear cup, ensuring the fabric mesh (if present) is centered over the speaker.
5. Secure Ear Pad: Carefully stretch the elastic rim of the new ear cushion over the plastic mounting ring. Work your way around the circumference, ensuring the entire rim is seated securely in the groove. If the plastic ring was removed, reattach it after the ear pad is in place.
6. Adjust and Test: Once installed, gently press around the edges of the ear pad to ensure a snug fit. Repeat the process for the other ear pad.

4. Care and Maintenance

Proper care will extend the lifespan of your ear cushions.

• Cleaning: Wipe the PU leather surface with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the material.
• Drying: Allow the ear cushions to air dry completely before use. Do not expose them to direct sunlight or high heat.
• Storage: When not in use, store headphones in a clean, dry environment to prevent dust accumulation and material degradation.

5. Troubleshooting

If you encounter issues, consider the following:

• Ear Pads Do Not Fit: Ensure you have the correct replacement ear pads for the Boltune BT-BH010 model. Re-check the installation steps, particularly how the elastic rim is seated over the plastic ring.
• Reduced Sound Quality: Verify that the ear pads are fully seated and creating a proper seal around your ears. An improper seal can affect bass response and sound isolation.
• Discomfort: Allow a short period for the memory foam to adapt to the shape of your ears. If discomfort persists, re-check installation for any pinching or uneven seating.
