Sony MDR-XB450AP Extra Bass Headphone Swivel Replacement

Introduction

This replacement guide was made for the Sony Extra Bass headphones, and if you are experiencing problems using the "swivel fold'' feature, these instructions can help solve that problem. There is a screw that holds the speaker to the headphones and with wear and tear the swivel action becomes less effective, replacement of the screw is necessary at this point. Be sure to check the headphones for other underlying problems before replacing the screw.
