There are so many great options out there for open back, but doesn't making it open back defeat the purpose of being wireless? This is clearly made for hifi on the go, which is a segment crucially lacking for those who prefer headphones to iems at a time where smartphones don't have an audio output and basically force you to go wireless or set up a complicated rig that isn't really portable anymore. To me this is the smartest move, but I'm wondering about your use case for something like this open backed. I don't really mind a full size amp and wire for the cases where sound leaking is not an issue but maybe it's just me. You may want to check out the Grado, I've heard good things about their open back wireless cans, but to me this is much more of a niche use case.
