I saw some buds where the charging case had a microphone which is a clever solution i hope more brands adopt.
That's the nothing new ear 3 buds yes. Pretty cool feature though they're too expensive compared to my Xiaomis to upgrade for it.
...so I have to walk around holding the case to my face of I want to take a phone call?
I mean it's better than having wind and background noise because the mics are by your ears...
the nuisance of another charger, little fiddly bits that are easy to loose, discomfort for some and expense,can add up the stress to the fuck it level
personaly I like a standard 1/8 jack, as it is backwards compatible with a huge amount of equipment
I removed the infotainment system from my truck, and replaced it with a shelf in the dash that has a 1/8 going to a power amp with a "high z" input,
hit play, bumpin tunes, everything is local
