Anyone heard these two and can make good comparison of them? interms of soundstage/bass etc

The HD380 may have a wider soundstage, but they are worse in all other departments.
The Q40 is more dynamic, have better bass, mids and highs.
The Q40 is a rather good closed headphone, the HD38o is one of the worst IMHO.
