heya.. am a newbie here. got a question for ya, would ya recommend da PX100 if i were to use it on da bus/train? im not soo worried bout da noise leaking out, but more on da the noise leaking in. i have been eyeing on da PX100 for a while. or maybe, i should get da PX200, since its a 'closed' one? is PX200 worth da 'isolation' factor? or am i better off with da PX100? thanx alot dude
