re: Loudest earbuds corded or wireless?

I'm not sure if you want them loud so everyone can hear what you're listening to or to drown out other sounds around you. If the latter, then I suggest getting noise cancelling headphones because you should never try to drive out unwanted sound with more sound because that will damage your hearing long term. If the former, then quit being a tool. You don't look cool and no one gives a shite what you're listening to.
