I currently have the er4p and love the insane clarity and detail of this cold sounding iem. I am looking for an iem that is the perfect complement (warm, fun sounding , smooth) , while maintaining at least half of the clarity an ety provides. I am looking to spend up to $250 and have tried the following Gr07- loved the sound and balance of this iem , however, hated the over the ear application. That was why ultimately killed it. Gr01- brighter and a touch warmer than the er4p, bass about the same. Was not too impressed. I listen to any and all types of music, and am open to suggestions.
