Replacing your ear pads is a straightforward process designed for easy and hassle-free installation. A small blue prying tool is included to assist with the removal of old ear pads and installation of new ones.
- Remove Old Ear Pads: Gently pull or pry off the existing ear pads from your headphone cups. Some models may require a slight twist or a gentle prying motion with the included tool to detach.
- Clean Headphone Cups: Ensure the surface of your headphone cups is clean and free of any debris or adhesive residue from the old ear pads.
- Align New Ear Pads: Take one new YunYiYi ear pad and align its inner rim with the groove or mounting ring on your headphone cup.
- Securely Attach: Carefully stretch the ear pad around the edges of the headphone cup, working your way around until the entire rim is securely tucked into the groove. Apply gentle, even pressure to ensure a snug and complete fit.
- Verify Fit: Once attached, gently press on the ear pad to ensure it is firmly seated and does not easily come loose. A proper fit is crucial for comfort and sound isolation.

4. Maintenance
To ensure the longevity and continued comfort of your YunYiYi ear pads, follow these simple maintenance guidelines:
- Cleaning: Wipe the ear pads gently with a soft, dry cloth to remove dust or light smudges. Avoid using harsh chemicals, abrasive cleaners, or excessive moisture, as these can damage the material.
- Storage: When not in use, the ear pads are designed to return to their original shape. For extended storage or travel, utilize the included YunYiYi velvet pouch to protect them from dust and potential damage.
- Avoid Punctures: Be careful not to puncture or tear the surface of the ear pads with sharp objects.

5. Troubleshooting
If you encounter any issues after installing your new ear pads, consider the following:
- Ear Pads Feel Loose: Ensure that the entire rim of the ear pad is fully tucked into the groove of the headphone cup. Re-adjust by gently stretching and pressing the edges until a secure fit is achieved.
- Reduced Sound Quality or Isolation: A poor acoustic seal can lead to reduced sound quality. Verify that the ear pads are seated correctly and evenly around the headphone drivers. Ensure no gaps exist between the ear pad and the headphone cup.
- Discomfort After Installation: While the memory foam is designed for comfort, allow a short period for the ear pads to conform to your ears. If discomfort persists, double-check the installation to ensure no part of the ear pad is creased or improperly positioned.
