Good IEM-s don't really need ANC. If the silicone tip doesn't isolate enough you can use foam tips that basically function like hearing protection earplugs.
No battery is even better than replaceable battery.
Wired IEM-s never get obsolete. At worst you'll need to replace the silicone tips from time to time, or the cable and today even 20€ Chinese IEM-s have replaceable cables. With good care wired IEM-s can last decades.
