IF you want name-brand noise-cancelling headphones that take AAA batteries (instead of having a built-in rechargeable LiIon battery), then you are in luck because for the next five days and change (from blog-posting time here) Massdrop is offering the new condition PSB M4U 2 noise-cancellers (closed-back, over-ear) for $80 with free US shipping. They will ship in late April 2020 from Massdrop…

They have a generous accessories package given the price, an extra set of earpads, two cables, semi-hard case, and a few small things (two AAA batteries, cleaning cloth, carabiner, 1/8 to 1/4 adapter, airline adapter).

NOTE: these are ANC-only, no wireless/bluetooth!

PS: now just because they take AAA batteries, it doesn’t mean you have to use disposable batteries. You can also use rechargeable AAA batteries and depending on your usage patterns you can buy the low self discharge kind (last longer if left unused but not as high mAh) or the regular (higher mAh but deplete faster if left unused)…
