I use noise-cancelling headphones. Depending on how much focus my current task requires, I'll listen to different genres. For intense concentration, I'll blast ocean waves. For medium-difficulty tasks, I listen to classical music or pop music in a language that I don't know (so that I'm not distracted by the lyrics). For easy tasks, anything goes :)
