Query: a dream at work

When I moved cubicles recently I ended up next to two heavy sighers, a pounding typist, peripheral conference and personal calls, and similar audio distractions. I'm completely happy with these headphones as they dramatically reduce or eliminate office sounds, make listening to music real fun again, work with or without an attached audio source, are extremely comfortable and light, and are very portable for trips. The circuitry does not introduce static. These are just perfect and I may be getting another pair for the commute.
