How to Replace the Power Button/Switch on Bose QC35 Headphones

The plastic power slider on the Bose QC35 headphones has been known to break so that it will no longer push the switch inside of the headphones to turn them on or off. We sell reinforced versions of that plastic slider and this guide explains how to install them.

Repair Difficulty: Moderate

Time to complete: 30 Minutes

The tools and parts that you will need for this repair:

    1. A New Replacement Power Switch
    2. Nylon Spudger Tool (your fingernail, a guitar pick, or small plastic screwdriver will also do the trick. You can use metal pry tools, however, you run a higher risk of damaging the plastic of the headphones)
    3. Small Phillips Screwdriver 
    4. Double-Sided Tape (For securing the cloth mesh after you have replaced the power button. This might not be necessary as the old tape could still be sticky, we usually just replace it to make sure the cloth doesn't fall out of the earpad)



1. Remove the earpad

The right earpad is only held on by small clips that run around the edge of the speaker housing. Being careful, you can pull it off of these clips with nothing but your fingers. Simply peel the earpad away from the edge, then pull it away from the housing.

2. Remove the mesh

The mesh that sits inside of the earpad is held on to the speaker housing by two pieces of double-sided tape. You can pull this tape off of the housing slowly to ensure that you do not rip the cloth mesh.

3. Remove the outside cover

There are 3 screws underneath the cloth that can be removed using your Small Phillips Screwdriver. Make sure to keep the screws in a safe place so that they do not get lost. All of the screws are the same length and size.

With the screws removed, the outside cover will only be held on by some small clips on the inside of the housing. This is where you want to use a plastic pry tool to carefully pry around the edge of the cover until you have it removed. ***Using a metal pry tool will likely leave marks in the housing and gives a higher potential to cause damage to the headphones. We recommend using something plastic.

4. Replace the power slider

 The broken plastic switch will be sitting on top of the actual power slider underneath the cover that you have removed. You can pull it off of the slider and place the New Replacement Power Switch onto it.

5. Reassembly

Start by putting the cover back on over the new switch and ensure that it is securely snapped into place. Make sure that the power switch works properly before moving on to the next step.

Reinsert all 3 screws into the speaker housing.

If the tape on your cloth mesh is still sticky, you can simply put it back on. If the tape is not sticky any longer, you can use some double-sided tape to hold it on. Just make sure to carefully remove the old tape before putting new tape on it.

Lastly, snap the earpad in place by peeling back the leather and placing the edge of the earpad into the rim of the housing. Once it is seated, apply even pressure around the entire edge of the earpad to snap it into place.
