Olympic Gymnast Laurie Hernandez's Must Haves: Lip Balm, Headphones, and More

Hernandez spends a lot of time on planes commuting between competitions and always has the Bose QuietComfort Headphones ($349) in her carry-on.

"I am a playlist fiend, and love listening to different genres, different instrumental scores, and obviously the new Taylor Swift album," she says. "The Bose ones that I'm currently using go over my ears and are waterproof and soundproof, and I feel like as long as I've got them on, everything's going to be fine."

Pro Tip: The Bose QuietComfort Headphones offer high-quality sound and effective noise cancellation. They have different modes — quote, aware, and custom — allowing you to personalize your listening experience.
