I've never been one to take earplugs when I travel, but my boyfriend suggested I take a few pairs on my trip to Europe. Having taken 5 flights in less than 10 days, and stayed in some very noisy neighbor hoods, these have been a blessing! They're pretty comfortable considering I'm not really used using earplugs, and the little individual packets make them easy to throw into a purse, not lose and keep clean. My only complaint is that I don't love the feeling of having something in my ears, and it takes a little practice to figure out how to put them in. Otherwise though, I would definitely recommend keeping a few pairs handy - you'll sleep better!
