When to replace Mu7 earpads
Over time, ear cushions wear down, flatten, or crack. This reduces the seal around your ears, letting in ambient noise and weakening bass response. If you notice less effective active noise cancellation or discomfort after long listening sessions, it is time for a swap.
Replacing the cushions is the most direct way to restore the original fit and performance of your headphones. The process takes only a few minutes and requires no tools.
Step-by-step replacement guide
- 1. Remove the old ear cushion: Hold the headphone firmly with one hand. With the other hand, grip the edge of the ear cushion and gently pull it away from the ear cup. It is held by a plastic retaining ring; work your way around until the cushion pops off. Do not yank on the cushion. If it resists, check for a hidden tab or rotate the cushion slightly to release the ring.
- 2. Clean the ear cup surface: Wipe the exposed ear cup with a soft, dry cloth to remove dust or oils. This ensures the new cushion seats evenly and does not trap debris against the driver. Avoid using liquids or cleaners that could seep into the driver mesh.
- 3. Align the new Mu7 ear cushion: Take the replacement cushion and position it so the mounting ring faces the ear cup. Match the orientation—the cushion’s shape should mirror the ear cup outline. Press the ring evenly into the groove around the cup. A common mistake is forcing the cushion at an angle. Start at the top and press down along the entire perimeter to avoid a loose corner.
- 4. Snap the cushion into place: Apply firm, even pressure around the entire ring until you hear a series of clicks. Run your finger around the edge to confirm the cushion is fully seated and there are no gaps. If a section does not click, remove the cushion and reseat it. A partial snap can cause the cushion to detach later.
- 5. Repeat on the other side: Follow the same steps for the second ear cushion. After both are installed, put on the headphones and check the fit. The seal should feel snug without excessive pressure. If one side feels looser, remove and reseat that cushion. A good seal is critical for noise cancellation performance.
