I have a TWS or two - heading out to walk to the shop, I hear 'battery low' and I know that my music will be punctuated by this warning every 20 seconds until the things turn off. Not very convenient.

The popularity of TWS is due to perceived convenience sure, but how much of its popularity is because people have no choice? I went out of my way to get a V20 phone back in 2018 because it has a headphone socket (gasp), but most people will blindly just buy what's put in front of them.
