I own a pair of Sennheiser HD600s and they are the most comfortable headphones I’ve ever had, and I love how they sound. I’ve actually forgotten I was wearing them until I got up and walked away only to have the cord yank them off my head. However a portable device will not drive them and they are open ear so will not attenuate background noise and others may be able to hear what you are listening too. So they are not good for travelling.
