I don't want to embarrass my friend, so in this story I will call him O., for Mr. Objectivity.

When first I saw the Audeze iSine models I wondered to myself, "What the heck are these for?" and, "Who will want these?" I'd never heard of an open acoustic in-ear before...heck, I'd not even thought of the possibility. Why in the world was Audeze even going down this road? I spent some time on the phone with Sankar Thiagasamudram, founder and CEO of Audeze, to gain some understanding.
