Most runners find wireless options to be the best ones. There's less to get caught or tangled when running, and there's also less pull on the earbuds or headphones because there aren't any wires connected to them. Having said that, some runners prefer the wired headphones, with the opinion that the sound quality and consistency of the signal is better than using something that works wirelessly. You may want to try different types and see what feels best for your specific running needs. Where and how hard you run may make a difference, too.
