Learn how to install and care for silicone headband and earpad covers on your Sony WH-CH720N headphones to keep them sweatproof, dustproof, and non-slip.

Quick answer

Silicone covers designed for the Sony WH-CH720N shield the headband and earpads from sweat, dust, and scratches while adding a non-slip grip. This guide walks you through installation and care steps so your headphones stay protected and comfortable.

Why silicone covers matter for the WH-CH720N

The Sony WH-CH720N uses a lightweight plastic frame and soft fabric earpads that can absorb sweat and collect dust over time. A dedicated silicone cover set wraps the headband and earpads in a waterproof, flexible layer that prevents moisture from soaking into the padding. The material also adds friction, so the headphones stay in place during workouts or commutes.

Because the covers are custom-molded for the WH-CH720N, they fit snugly without blocking the headphone’s hinge movement or charging port. Generic covers may slip or interfere with the folding mechanism, so a model-specific set avoids those headaches.

Trade-offs to consider

Silicone covers add a thin layer between your skin and the original earpad fabric. Some users notice a slight change in texture—less plush but more grippy. The headband cover may also feel slightly tighter at first, though the flexible silicone stretches to fit after a few uses.

If you prefer the original soft-touch feel of the WH-CH720N earpads, covers might not be for you. But if sweat or dust is a concern, the trade-off in texture is minor compared to the protection gained.

How to install and care for silicone covers on the Sony WH-CH720N

Clean the headband and earpads: Wipe down the headband and earpads with a dry microfiber cloth to remove any dust, oil, or sweat. Do not use water or cleaning sprays—moisture trapped under the silicone can cause odors or damage. A common mistake is skipping this step. Even a thin layer of dust can make the covers feel loose.
Install the headband cover: Hold the cover with the larger opening facing the top of the headband. Slide it over one end and work it along the band, stretching the silicone gently as you go. Center the cover so the padding section aligns with the top of your head. Check that the cover doesn’t bunch near the hinges. If it does, reposition before moving to the earpads.
Install the earpad covers: Stretch the earpad cover over the outer rim of one earpad, then press the inner ring into the groove behind the pad. Repeat for the other side. The cover should sit flush without wrinkles. A common mistake is forcing the cover over the pad without aligning the inner ring first, which can leave gaps that let dust in.
Check fit and adjust: Put on the headphones and move your head side to side. The covers should stay in place without slipping. If the headband cover shifts, gently tug it back into position. For earpad covers, press around the edges to ensure full contact. If the covers feel too tight, they will loosen slightly after a few hours of wear. Do not cut or trim the silicone.
Clean the covers regularly: Remove the covers once a week and rinse them with lukewarm water. Pat dry with a lint-free cloth and let them air dry completely before reinstalling. Do not use alcohol or abrasive cleaners—they can degrade the silicone. Skipping weekly cleaning lets sweat residue build up, which can eventually stain the covers or cause them to lose grip.
