So far liking the headphone, got a great deal from a fellow Head Fier. Just a few comments, interestingly that while this headphone has the appearance of a portable headphone, it feels like a high end solid build headphone with good weight. Careful in how you handle these headphones, because the grill have that ceramic coating or whatever its called, I can easily scratch. My pair already have a couple of minor scratches, so if you are planning to take them around be super careful.
The cable looks kind of generic nothing fancy, but I know it is not, 500 bones for a new one (are you kidding?). Love that the cable does not have a any micro-phonics whatsoever. I have own multiple custom cables that I can't stand because you can hear even your fingers rubbing the cable, so good on them. However I noticed the cup end of the cable does not have some type of strain relief, looks like that cable is welded into the connector. I think this could be an issue of durability, but i guess time will tell.
Sound-wise, well this is my first really expensive high end open headphones. For a brief time I owned the HIFIMAN Edition X V2, which I loved for the warmer and relaxed sound sig with good lows. I currently own the the Z1Rs and the Senn HD-58X (150 dollars great value). But now i understand when people talk about sophisticated high end sound. These definitely sound dont sound cheap, the thing that comes to mind is how balanced they sound across the freq range, and I mean it in a good way. Usually, when I hear people say that, I think oh no they mean no BASS. But this babies have very good solid bass and sub bass, but it just does not really overdone. I would say they sound very detailed but not clinical, with great mids and detailed highs but not overdone. I can't say they sound thin nor too warm, but just very just down the middle. All i can think is sophisticated LOL.
Now, my personal opinion, I think these are super expensive, even at the discounted price i got them, I still feel guilty about owning them LOL but I guess if you are used to expensive cans these should not be a problem.
Lastly, I don't talk about soundstage nor separation, because for me tonality is probably the most important for me, so I dont think I am the right person to talk about soundstage.
I am powering them with a PS Stellar Gain Cell DAC around 25-30 volume compared to the Z1R that only need from 8-15 , so these definitely need some juice. With my Dragonfly Red connected to the iPhone, I have to go almost all the way up.
Overall, great headphone, great all rounder.
