I buy these same headphones for $20 once every ~2 years, after the last pair breaks. I discovered that Koss Porta Pro drivers sound really good 20 years ago and I've been using versions of them ever since. It's better to keep buying new ones really because headphone speakers wear out and sound worse with usage.
I remember testing it and my 4yo really nice noise cancelling sennheisers sounded like shit when comparing them to a brand new pair of these
