Thanks for interpreting those graphs! I'm in a very blasphemous minority because piercing treble is exactly how I'd describe the K10UA. Sibilance on mine is at times intolerable.
Now now... Fan persons... No flame throwing. I'm not saying they sound bad. And no its not a sealing issue; seal and bass are spot on. But treble is still hot to my own personal ears. They're absolutely awesome for orchestral and metal. I just wouldn't use the K10 to listen to female vocals, or Gollum looking for his precioussss
You are entitled to your opinion, and bringing up the negative aspects of IEMS (actually everything here) is very important and seems to get overlooked, and items receive nothing but praise, only leading to people buying things, and being disappointed.(occasionally)
As far as your experience, I'm sure it's not unique, but definitely is on the rarer side of things from what I've read. Anyway, I'm far from a Noble fanboy, I bought the K10 expecting to not love it. I really tried to not like it... But I do. I'm a basshead, but enjoy the other frequencies. I don't enjoy piercing treble, and although the K10s are probably the brightest IEMS I own, I don't find the treble offensive at all. It's definitely a little different than what I'm used to, but I think the treble is done very well. It's borderline of being too much for me, but borderline is pretty much ideal, as it's as the limit of my tolerance or enjoyable level.
I really enjoy my K10s. It took some time, but I decided to keep them as they fit nicely in my collection and do something that my other IEMs don't. So I'm happy.
They are very well rounded, they don't do anything bad, and do everything good at least, if not great.
As far as Apple, I thought they were doing some new wireless tech, not Bluetooth? Nvm. Have my answer.
