If I hadn't been gifted a pair of beats earbuds, I could see myself believing similarly. The ones I was given were very nicely built, with tactile components that felt of significant quality, as though they were assembled with great care. They were also the muddiest, mushiest, and most unpleasant listening experience I've had in the last couple of decades outside of bad laptop / phone speakers or scenarios that used explicitly damaged components. When I first got them I thought that I had received a bad pair, only to find online that the sound profile was intentional.
Obviously shit earphones are going to sound shit. That’s true whether they’re bass heavy or not. So its a sentiment that is not contradictory to my point.
My point is having earphones and headphones that can offer a deep and rich low end without sacrificing sharpness a not novelty feature. And there are earphones and headphones out there that can do that. I know this because I’ve owned plenty over the years. :)
They were awful.
