I freely admit here that I am a full paying customer of Noble and own the K10. I was a Heir customer, owning a 4.ai and 5.0, and the K10 are actually my first set of customs.
I came to head fi looking to replace an aging pair of Shure E500PTH iems, and after looking at UE900 and W4R and Shure 535 I ultimately decide to try the 4.ai. It was very different from anything else I and ever heard, but I enjoyed them and they looked great. I did have a small problem and Heir at the time provided great customer service to get it taken care of. When the 5.0 was announced I order a pair because I did want more low end to enhance what I liked about the 4.ai. I posted some here about all that, but I am not a professional reviewer and have a busy work and travel and personal schedule, and most of my listening is done on airplanes or places with little or no internet access. So I don't write a lot about them.
I am not at all affiliated with Heir or Noble, but I must admit I was moved by some of Wizards posts about his life and challenges with a startup business and his family, which can be seen freely in his post history here. Perhaps as a man with a family who also travels a lot it struck a chord with me personally, and I have worked start ups and small business and understand what it is like to pour yourself into something and have a less than desirable end state (let's leave that drama out of here).
I was interested in maybe purchasing a custom iem, and contacted Wizard and eventually decided, freely and independently based on my own research, mostly here, to purchase a K10. Maybe I am a little crazy for doing this before anyone else had a copy and there were no reviews and Noble may not have even had a name. But I knew enough about hard work and start ups and business and life to put my trust in Wizard and his new company to build me a pair, and I gladly paid my hard earned money for them.
I have no reason to be anything but open and honest here about them and my opinions. As my first customs I had no idea what to expect. I was kind of surprised at how shallow the fit seemed, since I am used to foam tips and deep insertion to block plane noise. Ultimately the left side was perfect, and the right left my ear sore after using them, and I worked with bangkokkid and we decided that a refit was the best course of action.
When I had them, they sounded great. Words already written here articulate them better than I could. Deep rumbling bass, mids that were so clear but presented in such a way that you didn't have to listen so hard to get every little detail, the detail just is there. Highs unlike anything I had ever hear. Brit and extended and sparkly without ever being harsh or sibilant. Like not at all in any way ever sibilant. I actually had to adjust to how they sounded since there was so much high end detail I had never really heard before.
I will post pictures here of them, and I have to take accountability for the design. I really didn't let Wizard do his thing, and I got exactly what I asked for. I told him to go wild with the rebuild, and to not listen to my dumb ideas about how to design an iem. I would guess I will get back a work of art next time around.
All told, I was very happy when I had them, fit issue aside. If they had fit I would not have said one bad word about the design, since they were exactly what I requested. I am just taking the chance to since the fit wasn't right, make them as outrageously beautiful to the eye as they are to the ear.
If you have questions, fire away. All I can do is answer honestly since I have nothing else and no other motivation.
Here are some pics:
Sorry I'm not a photographer either...
