Battery life and replacement

Applies to:

  • QuietComfort® 15 Acoustic Noise Cancelling® headphones

Although it varies by usage, battery life averages 35 hours. The battery light indicator starts flashing when there are approximately five hours of battery life remaining.

When a replacement is needed, use one AAA alkaline battery (IEC LR03).

Note: Remaining battery life may vary when using rechargeable batteries. NiMH batteries, composed of nickel metal hydride, are recommended.
