Replacement ear pads for Pioneer SE-M521

These black sponge ear pads replace the original cushions on Pioneer SE-M521 headphones. One pair restores comfort and acoustic seal when the factory pads have worn, cracked or lost elasticity. The soft material conforms to the ear without requiring tools for installation.

Check headphone model and pad dimensions

Verify that the headphones are Pioneer SE-M521 before ordering; the pads are sized 100x80x30mm (3.94x3.15x1.38in) and will not fit other models. Inspect the existing mounting mechanism to confirm the replacement pads can be attached without modification.

Passive noise isolation and acoustic fidelity

The dense sponge cushions physically block outside sound, improving perceived isolation during listening. By restoring the proper seal around the ear, they help the drivers reproduce bass and detail as intended. No active electronics or power are involved, so there is no added noise or power draw.
