Wired. Bluetooth is just one more thing I have to charge. If they're not, I am totally unable to use it for that. They're way too easy to lose. and they both last about the same amount of time anyway. So why would I pay a crazy amount of something much easier to lose that won't last any longer that I constantly have to recharge? It's too inconvenient.
Plus, in general, you shouldn't have your bluetooth enabled at all times anyway because it's a massive security risk. You can be vulnerable to all sorts of things that way.
