Yeah, let's introduce a major structural flaw and a point of failure to a perfectly sound design :agony-shrooms:
And for what?
"Foldable headphones are so convenient and portable when you're not using them!!"
YOU WEAR THEM AROUND YOUR NECK WHEN NOT USING THEM, DIPSHIT
These stupid hinges turn cheap headphones from durable and reliable backups to instant e-waste
Source: just had a pair of cheap bluetooth headphones crack at the hinges because it was slightly below freezing
That was your first mistake.
I absolutely hated any kind of hinge on headphones when I had long hair, since if I didn't wear a pony tail, it'd get snagged.
