Shit batteries which only last until the warranty expires.

See the Cycle Life row?

& notice that there's no Lithium Polymer column..

Li Polymer lasts few charges.

It's cheap, though, & light, so it gets put in lots of things..

Making tech "disposable" so as to use enforced-obsolescence for repeat-sales, may be "profitable", but it wastes people's earnings & effort, too.

While wasting the world we're inhabiting.

"you can't serve 2 contradictory gods" principle is true: you can't orient to Right Action, if you are orienting instead to Effective Parasitism. They're different paradigms/orientations, & mutually-exclusive.

Ima echo paragone@lemmy.world, and add that it simply isn't as good.

So, like paragone said, the built in obsolescence of Bluetooth headphones by most makers is total bullshit and the world can't afford that way of doing things.

But holy shit, to get decent sound out of Bluetooth, you have to go pretty damn high end compared to what you can get on a budget wired because there's extra shit involved. Maybe someday Bluetooth will reach full parity in quality or transmission (hell, it isn't that far away if you ignore my picky ears), but when you tack on at least an extra thirty to fifty bucks (based on my last comparison shopping of wired vs Bluetooth from companies with equivalent models in both forms) just for the privilege of weaker quality and the annoyances of dropped connections here and there, even going high end isn't a sure thing.

Ngl, I have a pair of anker soundcore buds a friend gave me that I fucking love, and a sennheiser Bluetooth over ear headset that's both comfy and reliable alongside better than acceptable music quality. So I'm not shitting on Bluetooth audio entirely. I don't hate the idea, obviously. It's the execution and the fucking insistence of it on phones that reaches hate levels.

But, ignoring that, testing similar models of audio specific headphones side by side, wired vs Bluetooth, there is a detectable difference. And I'm middle aged with ears that have taken a beating via loud music and occasional firearm discharge without good earpro. So if I'm picking up a loss in clarity and soundstage with otherwise similar models, there's a gap.

Then you gotta deal with incompatibilities with older audio sources. There's some flat out amazing fucking gear for budget audio out there that's going to require an extra piece of gear to use the best Bluetooth cans. There's also amazing old gear that isn't budget, but when you're buying that stuff, you won't blink at the extra gear. But you do still need it for no benefit to the sound itself

Damn though, the freedom of movement is damn nice
