Hi there I own a Sennheiser PmX60 thinking that they would be ok. I was very much dismayed by the ammount of sound they leaked. (clearly audible from 20m away). i would no recommened these either as the wire is very flimsy and has already broken on my pair after only 6 months usage. Well i was thinking about upgrading to the PX100 or 200 but i can't decide as i have heard that the px 100 leak alot of sound but the px200 aren't as defined in the bass response. The usesage would be a mixture of travelling and home use so i'm truly stuck for choice. Please help!
