What to Pack For a Vacation in Cancún, From Swimwear to a High-Tech Fanny Pack

Apple EarPods Headphones ($19)

I like to bring these Apple EarPods with me to Cancun, as they are the most compact headphones I own (I also have the Apple Airpods Max Headphones), so they take up very little space in my carry-on. Plus, the jack fits into the audio sockets connected to airplane TVs, which comes in handy as some airlines charge for headphones depending on the ticket class you purchased.
