Bumping this with my own review: HEDDphone TWO Air Motion Transformer Headphones Review | TechPowerUp
Features comparisons to the original HEDDphone as well but overall this is a very unique, highly technical beast of a set that may or may not be to your music interests. It’s quite something how much body these AMT drivers add throughout the frequency response, especially the mids for the HEDDphone TWO.
