Recommend Good Headphones for Traveling

I'm going to Europe for the first time in some years and looking for a rec on good compact traveling headphones. Something compact, I have a pair of Beyer-Dynamics that are just too big, and hopefully not very expensive. In the process of saving for new speakers and I don't travel a ton so the cheaper the better. Thinking ear buds would be just too uncomfortable for an 8 hour flight. Thanks in advance for your help!
