I want to get opinions on these as I have owned a few. In fact I owned the now-discontinued ATH-ANC23BK. I used to own a few battery powered active noise-canceling headphones (some that Sony used to make back in 2003 or so) and I notice that these are not very common anymore (or at least to my knowledge). I really like these kinds of wired IEMs because they actually keep things nice and quiet and makes listening to the music really enjoyable.
I don’t know if there are any TWSs that have active noise-canceling or if that’ll be a thing yet.
Anyway, I just wanted to get conversation going on these and perhaps on active noise canceling IEMs out there because I’ve been very casual looking around for any particular modern products that offer that specific feature in exactness (battery powered, hard-wired old-school earbuds) or likeness (say a true wireless that has active noise canceling).
