But also, most modern earbuds usually sound quite good. Quality in general has become such a bizarre moving target, but here's my take: We've become so used to constant improvement at the expense of satisfaction. I can barely notice the difference between 1080p and 4k. In my mind they're both "good quality" and therefore I'm satisfied. Same goes for audio quality. I've used a few pairs of earbuds and they have sounded "good."
As a culture, we need to stop with throwing away of perfectly good devices, because it's extremely harmful to the planet's occupants.
