Installation Guide
Follow these steps to replace your headphone ear pads:
- Remove Old Ear Pads: Gently peel off the old ear pads from your Pioneer SE-MJ561BT-S headphones. They are usually held in place by a thin rim or adhesive. Take care not to damage the headphone's speaker unit or mounting ring.
- Clean Headphone Surface: If there is any residue from the old ear pads, carefully clean the headphone's mounting surface to ensure a smooth attachment for the new pads.
- Align New Ear Pads: Take one of the new YunYiYi ear pads. Align the inner rim or flap of the replacement ear pad with the groove or mounting ring on your headphone's speaker unit.
- Attach Ear Pads: Starting from one point, carefully stretch and tuck the ear pad's rim around the headphone's mounting ring. Work your way around the entire circumference, ensuring the ear pad is securely seated and flat against the headphone. Apply gentle, even pressure.
- Repeat for Second Ear Pad: Follow the same steps for the other ear pad.
- Verify Fit: Once both ear pads are installed, gently press them to ensure they are firmly attached and do not easily come loose.

Maintenance and Care
To ensure the longevity and hygiene of your ear pads, follow these care instructions:
- Cleaning: Wipe the surface of the ear pads regularly with a soft, slightly damp cloth. Use only water or a mild, non-abrasive cleaner.
- Avoid Harsh Chemicals: Do not use alcohol, solvents, or strong chemical cleaners, as these can damage the protein leather material.
- Drying: Allow the ear pads to air dry completely before using your headphones. Do not expose them to direct sunlight or high heat.
- Storage: When not in use, store your headphones in a clean, dry place to protect the ear pads from dust and environmental factors.
Troubleshooting
- Ear Pads Do Not Fit:
- Ensure your headphone model is Pioneer SE-MJ561BT-S. These ear pads are specifically designed for this model.
- Double-check the installation steps. Make sure the inner rim of the ear pad is fully and evenly tucked into the headphone's mounting groove.
- Reduced Sound Quality or Comfort:
- Verify that both ear pads are securely attached and properly seated. An improper seal can affect sound isolation and bass response.
- Inspect the ear pads for any damage or tears that might compromise their integrity.
