Overcharge - Noise Cancelling 700 Headphones

Is it safe to leave these headphones charging overnight, or do they have the same feature as the QC35s where they'll have a built-in auto shut-off feature that stops them from overcharging?


Re: Overcharge - Noise Cancelling 700 Headphones

Hi there @goddaniit , and thanks for taking the time to reach out!


As with all lithium ion batteries, there is no issue with leaving them plugged in after charging has been completed. The technology within them prevents them from being overcharged.

Effectively, when a full charge is reached, the headset will automatically stop charging to prevent the battery from being overcharged. 

Even while still plugged in, the battery level will have to drop below a certain point to trigger the charging again.


I hope this helps you make a decision you're happy with, and please return to me if you have any further questions at all!
