Questions about this item

How long will the 61 mAh earbud batteries hold a charge before they need replacing?

The 61 mAh earbud cells are sealed inside each bud; when run-time drops noticeably the whole earbud must be swapped as there is no user-replaceable battery.

What limits continuous playback when active noise cancellation stays on all day?

The 61 mAh earbud capacity is the first limit; with ANC active the buds drain faster than the 472 mAh case can replenish during short top-ups.

How much heat or fan noise appears when the buds and case charge together for hours?

No fan exists; the case and buds warm slightly during the USB charge cycle but stay comfortable to handle.
