Wireless Earbud Battery Replacement

I am considering buying one of the new Soundcore Liberty Air 2 Pro wireless earbuds. I have 2 questions

  1. Are they ANC headphones or just passive noise reduction
  2. We all know that the batteries in the charging headphone holder and/or the headphones themselves will no longer take a charge. All rechargeable batteries have a limited number of charging cycles in them. When the batteries die, can I have them replaced. I realize that I may have to send them to an authorized Anker service center to have this done and I know that I will have to pay for this if they are out of warranty. However, if I can’t do this, when the batteries die, I will have a throw them out which is sort of expensive and buy new ones.
