This can often resolve temporary Bluetooth connection issues. Additionally, consider testing the headphones with a different device to determine if the problem lies with the headphones or the original source device.
The noise cancellation on my Bose QuietComfort headphones is not working. How can I fix it?
A primary reason for diminished noise cancellation is improper fit. Ensure the earcups are creating a tight seal around your ears. Adjust the headband to achieve a secure and comfortable fit. Check the ear cushions for any damage or wear, as damaged cushions can compromise the seal. Replace worn or damaged cushions with genuine Bose replacements to restore optimal noise cancellation.
If the fit is correct, make sure noise cancellation is enabled. Some Bose QuietComfort models have adjustable noise cancellation levels or an “Aware Mode” that allows some external sound in. Use the button on the earcup or the Bose Music app to cycle through the noise cancellation modes and ensure it’s set to the desired level. If the problem persists, a software glitch might be affecting the noise cancellation functionality. Try resetting your headphones as described in the “Why won’t my Bose QuietComfort headphones turn on?” FAQ.
My Bose QuietComfort headphones only work on one side. What’s wrong?
A common cause of sound only coming from one earcup is a dirty or damaged audio cable, especially if you’re using a wired connection. Inspect the cable for any visible damage, such as kinks, cuts, or exposed wires. Try cleaning the cable connectors with a dry, clean cloth to remove any dirt or debris that might be interfering with the signal. If possible, test with a different audio cable to rule out a faulty cable as the source of the problem.
If you’re using a Bluetooth connection, the issue could stem from a software or connection problem. Try unpairing and re-pairing the headphones with your device. Also, check the audio balance settings on your connected device. Sometimes, the audio balance can be accidentally shifted entirely to one channel, resulting in sound only playing in one earcup. Ensure the balance is centered. If the problem persists after these steps, it might indicate a more serious hardware issue requiring professional repair or replacement.
