One thing to note about open circumaural headphones is that everyone around you can almost certainly hear what you're listening to. I work in an open office and like to listen to rather offensive comedy podcasts, so they're a no-go for me.

But I will say that Sennheiser is one of my favorite companies. I've purchased 5 different items from them over the past 7 years or so (HD 555, RS 180, MM 550-X, CS 686G, and the GAME ONE headset) and they all still work to this day with fantastic audio quality. I broke the MM 550-X, out of warranty and totally my own fault, and they still replaced them with a brand new set.
