After watching JV's video, while not agreeing with some of the things he says, I can see why he would think the headphone isnt to his liking.
Personally, my favourite headphones at the show of London. While I like well done treble, no matter how dark or bright something sounds, this headphone just has something about it that made me go into pure bliss haha. The speed and detailing was making me genuinely enjoy the headphone. While it did have dark or flat in terms of a frequency response treble, I usually hate that if its too dark. But this was just lovely. I normally also dislike planar's, I have only come across a few that I did in fact enjoy. Now I understand this is an AMT, not planar, but you get the idea.
Im a sucker for good design, and headphones ergonomically is often overlooked. The fact you can adjust clamp and fit is absolutely nuts. This to me is hd600 level of design because that headphone is a completely screwless design. While the hedd v2 has screws, it's the implamentation of the headband that makes it up there.
I'm trying not to shill, there are things I would hope for to be fixed such as the crinkling of the driver (which is normal, just could see it being annoying for some) and also trying to get the correct fit but that can be easily resolved with some self figuring out of the headband. But I am a huge sucker for good design, this is an example! Just doing something new for the better is what makes me love this hobby.
