The sunbird approaches. The Solis is wholly unique in the world of IEMs. It is the answer to the question; what if I could get the detail and timbre of an electrostatic headphone inside a housing that's the size of a nickel. It features two Danish electrostatic drivers that handle the high-frequency range and two specialized balanced armatures for both the mids and low end. What you get is a smooth relaxed presentation with fantastic detail and that electrostatic speed. For something truly unique, give Solis a spin.
