Adding weight to things is a tried and true means for increasing the price because the product “feels more expensive”.
I first came across this with wired headphones something like 40 odd years ago, actual slugs of steel to increase their weight, and it’s still happening today.
Ironically, headphones went the other way for a while, the lighter, the more expensive.
I’ve seen it in headphones, keyboards, mice, even monitors. No doubt it’s used in other products.
If your IEMs are too heavy I’m throwing them in the garbage straight away. They’re gonna pull on your ears like crazy, it’s gonna get real uncomfortable really quick
I bought a gaming mouse (despite not being a gamer), and it came with a set of weights you could clip under it to give it more mass.
