They are expensive. You can get wired earphones for 2 euros that actually work and are reasonably durable. It’s not a great loss if they fall in a puddle or if I step on them.
They are a lot more failure prone. Half of those I tried didn’t work or only half worked, and those that did work didn’t last very long.
They have shitty range. I can use a 10 meters extension cord with wired earphones if I want to.
They require charging. And it’s a law of physics that everything that requires charging always run out at the most inconvenient time.
Also THEY ALWAYS GET LOST. Wireless earphones, mouse, controllers… it doesn’t matter, if it’s not attached with a cable they’ll just disappear.
Wait… have you actually lost your mouse? Hilarious if true 😂
