Canpur CP622B

Most natural/realistic sounding IEM I've ever heard, besting a few others I've had the privilege of trying in the 3 - 8k range by a fair margin. Seperation, soundstage (particularly layering) and macro/micro detail are also a very clear step above anything sub 2k that I've spent extended time with, though I can't say definitively how their technicalities compare with competitors, since no other similarly priced IEM has made me want to keep listening the way these have.
