@OP: Let's get past the vanity/ego concerns and note that there ARE good reasons not to be wearing a big and/or obviously expensive headphones around in public spaces. First, it signals to other people that you are unapproachable, which may not be the intent, and second, it signals that you have things worth stealing.
So, what is the application? Good sound, sure, and also:
- Passive noise blocking to block out ambient noise?
- Active noise cancelling for trains, airplanes, loud ventilation fans near your study area...?
- In-ear only, in-ear with over-ear hooks, headband?
- Use with laptop, use with phone, use with mp3 player, all of the above, something else...?
He who laughs last, laughs first next time.
