Earbuds?

fwiw I have these too

  • nearly all functions are accessible via tap gestures
  • app is only needed to customize the 4th eq preset and to enable the optional hearing protection mode
  • the app works without network permission or an account, so you can revoke the permission or just skip the app entirely
  • battery, build, and sound quality is good for the price
  • carried in some physical stores like Best Buy so you can buy them with cash

since wireless earbuds are effectively and sadly disposable I think these are are a decent choice for casual usage
