In this detailed DIY repair guide, we show you how to fix a broken 14-pin connector on the Sony XM4 headphones yourself. Follow each step carefully and use the accompanying images as a visual guide to complete the repair with confidence.
Step 1: Extract the Right Earpad Cushion
1.1. Insert a strong metal pry tool into the seam between the earpad cushion and the earcup, then work your way around the perimeter till the two parts separate.

1.2. Remove the foam pad and set it aside.

Step 2: Extract the Main Wire from the Earcup Housing
2.1. Unfasten 4 silver screws from the earcup housing with a 2.0mm Phillips screwdriver.

2.2. Insert a strong metal pry tool into the seam between the touch panel and earcup and gently work the tool till the panel separates. Don’t yank or pull the panel, or you will tear the underlying touch ribbon cable.

2.3. Disconnect the touch ribbon cable and set the panel aside.

2.4. Unclip the main wire connector from the power board with precision tweezers.

2.5. Disconnect all the ribbon cables for better access to the main wire.

2.6. Unfasten the 2 small silver screws securing the power board to the earcup housing with a 2.0mm Phillips screwdriver, then move it out of the way with precision tweezers.

2.7. Unfasten the 2 silver screws securing the earcup to the hinge swivel with the 2.0mm Phillips screwdriver.

2.8. Pull the main wire out from under the power board, then separate the earcup from the rest of the headphone.

Step 3: Transplant the Wires from the Old to the New 14-pin Connector
3.1. Place the new 14-pin connector into the vise grip and tighten it just so that it’s securely held in place. Avoid applying excessive pressure, as that could damage or crack the plastic housing.

3.2. Break the plastic locks one at a time with tweezers to release the wires, then install them in the new connector. Go from left to right to ensure that the wires are installed in the correct order.


Technical Tip: Each wire has a top and bottom orientation. Align it correctly with the new connector, then press it firmly until it clicks into place. Repeat the process until all the wires have been transferred to the new connector.

3.3. Gently tug each wire with precision tweezers to ensure it is fully seated and securely locked into the connector.

Step 4: Reassemble the Sony XM4 Headphones
4.1. Push the main wire connector back under the power board.

4.2. Align the earcup with the headband hinge swivel, then secure it in place by fastening the two 2.0mm Phillips screws.

4.3. Push the main wire into the groove on the earcup with precision tweezers.

4.4. Align the power board with the earcup housing, then fasten the two 2.0mm screws.

4.5. Tuck all the internal wires into the slots provided on the earcup housing, then plug them back in.

4.6. Slide the hinge arm back into the assembly.

4.7. Reconnect the touch panel ribbon cable.

4.8. Install the touch panel into the earcup, then flip it and fasten the 4 silver screws.

Step 5: Install the Earpad Cushion
5.1. Install the foam cushion in the earcup.

5.2. Align the tabs on the earpad cushion with the grooves on the earcup, then press them together till you hear the retaining clips click into place.
