I really prefer an over-the-ear headphone for an office environment because they keep out external noise and, I presume, leak less sound to my co-workers. After years of habituation, my brain focuses more when I wear them. I really liked a noise-cancelling headphone for airplane travel (when I was traveling a lot), but the one I had didn't have good enough sound quality for me for regular use. Although I like the sound quality of Apple EarPods, they don't fit me well and my eardrums feel assaulted after using them. My two over-the-ear picks: Sony MDR-V6: basically flat response, great price point (~100 USD). I can't compare them to higher priced cans, but I have enjoyed them for 30+ years. One difficulty, though, is that the ear pads can pop off (especially after they've been replaced once) so they require a little extra care when traveling. Audio-Technicia ATH-M40+. I loaned out my MDR-V6 (long story) and I thought I'd try something different. ATH-M40 is also over-the-ear, basically flat response, similar price. I don't feel I get as much detail in the sound, though it's not dissatisfying enough for me to look further. They are much easier to travel with because they fold flat and the cord tangles less than the MDR-V6.
