Probably around the pandemic when people became extra wary about hygiene - at least that’s my observation. I’ve also noticed that people listen to voice messages like this - if you’re in a loud environment and don’t have headphones, it kind of makes sense. It still looks stupid, and for normal phone calls it is stupid, since both the earpiece and the microphone are optimised for having the phone on your ear.

Before that, see it a lot in construction and in places with a lot of noise so you can’t hear off speaker
