Well, after giving it some time, all I can say is that they're a good pair of portable cans but I'm not sure if they're really worth it. I definitely overpaid for it and it was partially my fault (customs and some paypal fees I had to pay because I was being stupid). But even so, at the price of $260 CAD (210 USD), you're getting into full sized mid-fi headphone territory and there a plenty of other options at that point. Unless what you're seeking for is absolute portability and aesthetics, I think you should take a look elsewhere until these goes down in price.
But let's talk about the actual headphones. First of all, I think they are absolutely stunning because of that mirrored finished cup, but they attract fingerprints like crazy. The detachable cables are thick and supple and there's not too much weight to them so you won't feel any tugging. They snap on securely and requires some force to take off. There's plenty of strain relief on both ends so I think it'll hold up well in the long run. The headband has enough padding which feels nice and comfy on your head and the clamping force isn't too bad so I think they're quite comfortable for long listening sessions. My main concern though has to do with isolation and the long term durability of the swivel hinges. The pads aren't thick and supple enough and the clamping force is relatively light so they don't completely press on your ears evenly and thus you get ambient noise coming through. In terms of the swivel hinge where the earcups attaches to the frame, I really wished they would redesign it and maybe use some metal instead of plastic. I feel like they would fail eventually just like my old pair of ATH ES55 with the same hinge design. Lastly, there's the problem of fit and I think it's biggest flaw. At its most extended position, the cups just managed to cover my ears and I'm someone with an maybe smaller than average head. So for someone with a larger head or maybe for those who wants to wear this over something else,I think it definitely poses a problem.
Onto the sound, I'm quite happy with it, but it's not the kind that impresses for the price. I also can't compare these to the ES7 which I think is the question that everyone's asking but I guess it should be quite similar from what I've read. It's energetic with plenty of low end thump. The bass sounds solid, with plenty of power for something this portable, but it's not the kind of bass that rattles your ears or digs really deep. It's a kind of softer bass, with a little more emphasize on the mid-bass and lower mid-bass. I really like how it transitions into the mids so you get this cohesiveness, which I think is it's biggest strength. There is more bass than I would expect and it's certainly a more prominent aspect of the sound signature. The lower mids and mids are smooth and very intimate, forward and engaging with none of that resonance and hollow sound you get from some closed headphones and that surprised me. But I feel that there's too much focus in this region, and not enough in the upper mids. There's a lack of air to the sound which hurts the overall timbre especially when listening to female vocals and acoustic pieces. Things like snare drums or acoustic guitars are a bit muted in comparison. The highs are nicely done and extends quite well beyond the midrange. There's nice weight and texture to the lower treble but a bit of grain in the higher frequencies. There's no sibilance to speak of and overall it performed better than I expected. Soundstage wise, it's got more depth than width and it's surely an intimate kind of sound. Instrument separation is alright and the bit of depth helps in this regard.
With all that said, I think they're a capable pair of portable cans with potential to sound great through the help of some modding and refinement. The high price of entry of $260 isn't in it's favor and there are fit issues as well. Based on sound alone, I think they slot in between the $180 - $200 (150 USD?) range, so the question that remains is whether the detachable cable and and portability alone is worth the premium (or that much more than the ES7?)
