Step-by-Step DIY Guide to Replacing a Cracked or Broken Outer Earcup Housing Cover on the Bose QuietComfort (QC) 45 Headphones at Home
In this detailed DIY repair guide, we show you how to replace a damaged external earcup housing on the Bose QuietComfort (QC) 45 headphones yourself. The repair process is similar for both sides. We will highlight any differences as they appear. Follow each step carefully and use the accompanying images as a visual guide to complete the repair with confidence.
Step 1: Extract the Earpad Cushion
1.1. Grab the earpad cushion with your fingers and pull it off the retaining clips on the earcup.

1.2. Grip the mesh and gently pull it away from the earcup. It is secured with double-sided tape, so use a flathead screwdriver to carefully peel it off and preserve it for reuse during reassembly.

Step 2: Extract the Broken, Cracked, or Damaged Earcup Housing Cover
2.1. Unfasten 3 screws from the right earcup (or 2 screws from the left earcup) with a 2.0 mm Phillips screwdriver, and set them aside in one of the slots on the rubber work mat.

2.2. Flip the earcup gently to dislodge the housing. If a clip is stuck, poke it with a flathead screwdriver or tweezers until the housing pops out.

2.3. Unplug the ribbon cable for the buttons from the PCB. Use a flathead screwdriver or precision tweezers to remove the adhesive patch covering the connector.

Step 3: Install a New Earcup Housing
3.1. Grab a new earcup housing, then connect the ribbon cable to the PCB. Put 1 drop of Joe’s cold press adhesive over the connector and let it cure for a few seconds to secure the ribbon.

3.2. Gently flip the earcup housing to align the screw holes, then fasten the 3 screws on the right side (or 2 screws on the left side)

Step 4: Reinstall the Earpad Cushion
4.1. Align the mesh with the earcup, then press down on both ends so that the double-sided tape sticks to the earcup housing.

4.2. Grab the earpad cushion and align the clips before pushing down with your fingers. Once you hear all the retaining clips click into place, give it a tug on all sides to confirm the earpad cushion is securely installed.
