I am a graduate student pursuing my PhD in Physics. I work as a teaching assistant mostly teaching mechanics and electromagnetism to the freshmen and sophomore students. I love my job but after a whole day of teaching, I need to relax and get back my sanity in order to concentrate on my research. Unfortunately my office is right beside the noisy chemistry undergraduate labs which makes it almost impossible to get any sort of relaxation. I mostly use IEMs but have been thinking of buying a nice closed over-ear Senns for some time. The momentum fits nicely into my lifestyle not only as my office cans but also during the long walks that I usually take to clear my head. I have a friend circle who are very much interested in music but think that buying an expensive set of headphones is not worth it. The momentum will also help me show to my friends how much a quality headphone can help them enjoy their music.
Imagination is an important ingredient in enjoying music too. When I go on a long walk, I like to use on-ear headphones for safety and curtesy purposes, so I know what's going on around me.
