The verdict
If you often mix on a studio monitor system, or are simply seeking a reference headphone, the Neumann NDH 30 are worth considering. They don't really have a wow factor, but they work well as a professional tool for picking out details in a mix.
✓Liked: Neutral reference sound, Aluminum build
✕Could be better: Price, Weight, Cloth ear pads, Lack of low and high frequencies
