Beyond HD Applications
  • Can be used with most headphones regardless of Impedance.
  • The CB adds a dose of control and smoothness to the equation without cutting back on the detail at all. In fact, there’s more to be heard in the way of textures and subtleties, while the presentation is more refined and the low end tows the line right up to eardrum creaking levels.
