Umm, ATC also has its issues, such as requiring to be powered (battery). IMO, the most appropriate choice for your needs is the Audio-Technica ATH-A500. They are full sized cans, but they are not too bulky, and I am inclined to say they are designed for outdoor used in mind (I am pretty sure that the default plug is the 1/8" although it provides an adapter for 1/4") - and I saw quite a lot of people use those in Tokyo subways etc. They are closed meaning that they will seal off some of the background noise. They are very good choice for gaming and MP3s (quite often recommended actually).
