Q&A
Q: Can I use the headset even when the noise canceling function is turned off or the battery is exhausted?
A: Yes, the QC® 20 headphones can still play audio even when the battery is dead and the device is powered off. However, you won't be able to use noise cancellation or Aware mode, and the active equalizer, which electronically provides more realistic audio reproduction, is disabled. Because these technologies require power to work.
Q: Which devices can be used with the QC20 headset?
A: The QC20 earphones are specially designed to work with select Apple devices as well as Samsung and Android™ devices. An in-line microphone and one-touch answer/end button support seamless switching between calls and music. But some phones may require you to hold down the "answer/end" button for a few seconds to perform these functions.
Q: Can I use the QC20 headphones in rain and snow?
A: No, the QuietComfort 20 Active Noise Cancelling Headphones are not suitable for use in wet environments.
