Similar to the "headphones for home" topic, but with different parameters.
Task: listen to the music via the iPod. Very rarely — in the premises connecting to a PC.
Form factor: "monitors". It is possible in principle, and false if they fit the conditions. Will not fit ear plugs/ear drops and the like.
Priorities in parameters:
— More sound insulation.
— Ergonomics. But not at the expense of the options above.
Budget: up to$250.
What about the Numark PHX, AKG K518, Ultrasone DJ1?
