These leak very little sound compared to other over-ear headphones. The rear side of the ear cups is fully closed, which effectively minimizes sound leakage. With these, you can fully enjoy your music without disturbing people beside you.
The headphone cable is coiled and is about 10 feet long. This is great for studios, however walking around in public with these headphones on can be awkward. The cable cannot be removed and has no remote or mic.
These headphones provide pretty good soundstage reproduction. Considering how good these headphones isolate sound which can have a huge negative impact on imaging and soundstage, what these headphones can give is definitely commendable.
The sound detail of this headset is superb. While listening to music you can clearly hear all the elements, from vocals to minor cymbal crashes. It also provides good spacial sound, since it offers distinct directional sound.
