Replace Your Bose QC35 Headband: Step-by-Step Guide

Quick answer

You can replace the worn headband on your Bose QC35 headphones with a compatible Brainwavz replacement headband. The process takes about 15 minutes and requires only a small Phillips-head screwdriver.

Step-by-step replacement process

1. Remove the old headband cushion: Use a small Phillips-head screwdriver to remove the two screws on each side of the headband (four total). Gently pull the old cushion away from the headband arch. Keep the screws in a safe place; they are small and easy to lose.
2. Clean the headband arch: Wipe the plastic arch with a soft, dry cloth to remove any adhesive residue or dust. This ensures the new cushion adheres evenly. Do not use liquid cleaners or alcohol; they may damage the plastic.
3. Align the new Brainwavz headband cushion: Position the replacement cushion so that the screw holes line up with the holes on the headband arch. The cushion should sit centered and flat. Check alignment before inserting any screws; once tightened, adjusting is difficult.
4. Secure the cushion: Insert and tighten the four screws using the Phillips-head screwdriver. Do not overtighten; snug is sufficient to avoid stripping the plastic threads. If a screw feels loose, it may be cross-threaded. Remove and reinsert carefully.
5. Test the fit: Gently press the cushion to ensure it is firmly attached. Place the headphones on your head to confirm even pressure and comfort. If the cushion feels uneven, loosen the screws slightly, adjust, and retighten.
