By “always work” I was referring to them not needing to be charged. I don’t know how many times I’ve pulled out a pair of wireless headphones that I haven’t used in a while, only to discover that they’re dead. With wired headphones, you plug them in and they work. That’s it. No fuss, no muss. Plus, if you’re using them with your phone and your laptop, you don’t have to worry that your headphones might still be connected to your other device.
