Pros: Fantastic clarity, treble and detail. Tasteful colored mids. Great build and comfort.
Cons: Weak bass
The AD700 are one of the best under $100. Especially if you really don't care about bass.
All is said about how good the headphone is, is in the PROS section but the bass really just kill this headphone. Even for non-bassheads, the bass can be considered somewhat weak.
However this headphone also has a fantastic soundstage which would make it for gaming. Many users on head-fi use this with a boom mic mod and is a much cheaper and much better solution than many headsets.
Overall a great sounding headphone.
