The HM5's do not leak at all, it actually really surprised me. Even at full blast, you cannot tell if someone is listening to music from 3 feet away. I generally listen to music while at work so the HM5 pads worked out perfectly. I can listen to whatever I want at whatever volume level and not disturb anyone else. That is, until to take the headphones off while the music is still playing. Then everyone can hear it.
They can double as small desktop speakers when off the head.
