I'm using the QuietComfort 20 (QC20) headphones with a laptop, so a power source is always within reach. Should I keep the headphones constantly plugged into USB as a power source in order to reduce the number of the battery discharge cycles (to prolong the battery life) - or will doing so actually reduce the battery life ?
Thanks for posting!
I can confirm the QC20 headphones will work while charging. I wouldn't recommend keeping them plugged in constantly as this can negatively affect the battery life of the product.

Is it not vice versa? When a device is constantly plugged in, battery is not used right? So we spare the charging cycles. The only downside is that we keep battery charged at 100% but there should be some limits set so it is not actually really at full battery capacity.
