Whomever is tuning these IEMs over at ISN really knows what they're doing. Just threw on some old tracks that I know like the back of my hand, but this is the first time I've heard them through the Neo 3. Just spectacular clarity, separation, tonality, and texture. Sure, there are some soft spots overall (sub-bass could use some help, decay is a bit fast in general, etc.), but nothing that detracts from the experience. Somehow, the Neo 3 manages to spread out the staging wide and deep, without cutting back on the upper mids/treble at all. Cymbals and guitars are accurately represented but still somehow provide a deep soundstage, which is NOT easy to do. There is some sort of sorcery afoot here.
Honestly, Neo 3 has the best planar implementation I've heard yet, and I've heard a few (Timeless, Dioko, Szalayi, EDP ACE, S12). Really a groundbreaking achievement by ISN, which has been largely overlooked by the audiophile community from what I can tell here and on other forums. I remember when the 7Hz Timeless was released and everyone was creaming their jeans about how revolutionary it was. Sure, it was superbly tuned and overall an excellent single-element IEM, and it had some obvious flaws, but for the price tag it was heralded as a breakthrough. The Neo 3 is several levels above the Timeless (quite frankly it pains me to even mention them in the same sentence), with a smaller planar element and tuning that is FAR superior, at a very slightly higher price tag. And yet here it sits in relative anonymity. Go figure.
Hopefully it will eventually catch on with the general crowd and finally gain the recognition it deserves. Really spectacular unicorn they have created.
