How to Replace the Power Button/Switch on Bose QC35 Headphones
Is the power button slider on your Bose QuietComfort (QC) 45 wireless headphones loose, wobbly, or stuck inside the outer case? Does the slider switch feel loose, require multiple attempts to turn the headphones on or off, or fail to function entirely? If you’re experiencing any of these issues, the power slider spring switch may no longer be making proper contact with the microswitch on the circuit board. Replacing the spring switch can restore proper operation and give the headphones a responsive feel.
