Not to mention reliability. I had a $350 pair from Beyerdynamic that was really nice, but after 3 years of extremely gentle use (I only used them to listen to music in bed) the cable developed intermittent noise issues. Could I get them fixed? Sure, there’s probably a high-end audio store that would fix them for some large portion of the purchase price. But that’s probably true for most expensive wireless headphones as well. Instead, they just sat unused in my nightstand for a few more years and then got thrown away when I moved last year.
