Fairphone Fairbuds launch with replaceable batteries, titanium drivers and ANC

Counterpoints:
- 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.
