It'll be a good comparison. Both are excellent earphones, and I find them well suited for rock and pop music. To me, they have more similarities than differences. Both have lush midrange presentations that allow vocals to sound powerful yet intimate. Still, if I have to choose 1 IEM between the 2, it's definitely the K10.
Nevertheless, enjoy your time comparing the 2.
It's not happening anymore unfortunately and my opinion of Noble Audio has greatly diminished. They were very helpful and accommodating (very much so) earlier in our conversations, but it turned out to be extremely unprofessional because I had asked for too much (even though I requested and didn't demand)... This followed up with insults towards me..
Maybe the build quality is indeed a little better, but I'm not sure at this point based on various people's complaints about theirs breaking down. Not a big fan of the whole made in China aspect either. Not so much for me after research.. There's a reason why JH Audio is the leading custom IEM manufacturer in the world and I wouldn't trust this startup with my money.
I have not tried these personally, but I can't imagine they compare to pure SQ that JH Audio has.. Jerry knows his stuff - and his patents make it very hard for manufactures to compete even though some come close.
My experience with JH Audio is that it they may not be extremely easy to deal with on a CS level, but they always honor what they say and follow trough. I initially was peeved off with them but I'm extremely satisfied with how they've handled all of my repairs now.
Moral of the story: to each own, but I'm sticking with JH Audio. Yes, this may have to do with with how Noble handled their conversations with me, but I truly think now that I look back that there isnt really a comparable company to JH.
Little chart of my analysic:
JH Audio:
-Established brand in the industry
-Patents that no other company can boast (freq-phase, cross-driver techniques)
-Best SQ in the market
-Most reliable - also for repairs, all done based in United States and they honor no matter what
-Made in USA
Noble Audio:
-New startup with a product that people are excited about
-Made in China
-Possibly better build
-Some say SQ is equal or better (I highly doubt it, honestly - I think it's placebo, but this is pure assumption as I've never tried)
ALSO something to think about: this is a startup after all. What will happen years down the line if they don't end up maintaining business. What does this mean for warranty support with your current IEM's (these are after all not cheap and you'd hope that they'd last a long time).
JH Audio products have proven track record to last SEVERAL years and more. No record with Noble - and based on the followers in this forum, it doesn't look promising. Aesthetics can be top-notch but who knows where and how they source their drivers etc (China).
I am not biased to one company - maybe a little for this post as Noble left me with a sour taste in my mouth.. But these points mentioned above seem pretty legitimate to me. If you're enjoying Noble's offering, that's great.. I just won't trust them with my money if their customer service got so hot tempered with me over the smallest of disagreements (I was simply asking for a higher discount rate and they got extremely offended, which I understand - but again, I never forced it upon them. I told them what I wanted to spend, if they didn't want to honor they could've said no dice and I would've contemplated it again).
