Pros: Immediately impressive lows; Exceedingly transparent and resolving mids; Resolving and aggressive highs. Great soundstage + separation.
Cons: Some moderate 8-9K sibilance. Somewhat thin sounding mids.
Despite a couple "flaws," what it does right, it does amazingly well. I would wager it competes very favorably in the company of > ~$250 range IEMs. More details found in the impressions thread.
This is not a full-blown review. I just wanted to add a rating and justify it.
Value (4.5/5): Offers more quality than I was expecting for the pre-sale price.
Audio Quality (4.5/5): I would give audio quality a full 5 if not for the 8-9k spike. Not going to detract for sound sig preferences.
Design (5/5): Love the refined look and finish (it doesn't scream for attention), detachable cables, sturdy housing, assortment of tips and accessories.
Comfort (4.5/5): I think these have a bit of weight to them in the ear, and I've felt some soreness during extended wear (3+ hours). Otherwise, a comfy and secure in my ears.
Isolation (4.5/5): Good isolation both coming in and going out. Low microphonic noise contribution.
