My point is every headphones will leak no matter what if you listen in an absolutely silent environment. Every headphone will leak in a mildly noisy environment if you are rocking out in high volume. If you are so concerned about sound leaking out (your #1 priority) then get an IEM and that's about all you can get. Both M50 and 580 will leak if you play loud enough and close enough to the headphones.
Well I would prefer it not to leak in the library, I would probably listen at moderate volumes. As for people knowing what I listen to, I could care less. I just don't want to be "that guy" always playing music that people can hear. At home I'll be both listening to music & gaming, but out in public it will probably be just music.
My roommates said they could care less, but I only recognized it as being polite. The problem would also be that sometimes Id be in a noisy environment, which would most likely cause me to raise the volume..which would in effect also leak more sound and bother others. Such a scenario would be friends watching a moderately loud movie in the living room, and Id be sitting at the dining table which would only be a few feet away (same room, just different sections)
Im also not too crazy of IEMs (but to be honest I haven't really researched them. I worry of losing soundstage mostly), I don't like sticking them in my ear..feels odd. Not to mention they slam music directly pointed at your eardrum. A friend of mine owns a pair of headphones(RP-HTX7) quite capable of having no leaks. True that it does leak very little, but it's quite ideal. The PRO550's I owned previously however were not ideal at all.
My dilema is that I'm afraid of committing to the HFI-580, which is said to leak very little to no sound, when the PRO900 seems as if it would be quite an improvement on all aspects(though I havent read your review yet x]) such as bass, mid/highs, soundstage.. though assumingly leaks more sound. I hope it's not as the PRO550's were, they almost sounded open, and those had (p)leather pads.
