I listened to them at the canjam for about 5 minutes (sorry, not in the market for new headphones and I didn't even know what they are, didn't see any marking on the outside), driven by the KS tube amp (6 small tubes plus one big tube inside). Source was some kind of tablet ---> some kind of DAC. Don't know what interconnect was used.
- The looks is quite "unpolished" which caused me to mistaken them as prototypes. Didn't realize that will be the final look. A little to retro for my taste. However the functionalities are all there, and I suppose some people might actually prefer the look.
- Very very light, almost no weight. Very comfy.
- Open back design, no sound insulation.
- The sound is very smooth, no bite whatsoever. I was playing some Diana Kroll song (don't remember which one, but it was from the All for you album).
- Bass is typical electrostatic type, good quality but not much impact. Somehow I got the feeling the diaphragm tension is probably very light, the bass felt a little loose at times. It could have been the amp too, tough.
- Can not comment on detail, air, sound stage etc, as the listen was too brief and the surrounding was a little too loud and I don't know the how good the source is.
Didn't realize they are already in production, I didn't ask the price at the show. Now it looks like the phones are $625. I am not sure whether I would consider buying a pair if I was in the market for open phones. If the price tag was $400 it would be seriously tempting.
About the build quality: these are a little more flimsy comparing to the SR-Lambda I had, but they are really not that super delicate either, I'd say about the same as my ESP950. Since these are super light (probably half the weight of the 950), they might actually have better chance to survive an accidental drop....
