You can add a private DNS in the settings. It’ll allow you to have a dns level ad blocking experience without having to use any of the dubious ad blocking apps. You also don’t need root or a VPN.
I’m using my own dns server, but keep in mind that it needs to support DoT. You can’t just enter any IP, because of the certificate check (the dns requests are encrypted using TLS).
dns.adguard.com works, but as is the case with all dns services, they will be able to see every domain you access. So keep that in mind.
Every earbud I had broke at least once during their warranty period. My linkbuds S recently broke the third time. Only one of my issues was battery related, but its still nice to have the option to use them after the warranty ends.
