Nice review VZ. I am getting some NT6 very very soon so eager to hear how they compare to your NT6 Pro. I would also like to know how they compare to the 335, even if the sigs are totally different.

I picked up my JH13 yesterday and so far so good. I'll be pairing them mostly with my Fiio X3 dap and if today  is any indication it is a very good pairing. The fit seem good so far but I'll give it a week or so before I make any judgement on that.
 
The feel of the customs is definitely different than my other customs. My guess is that JH Audio changed the finish of them. The JH13 feels more smooth to the touch than my other customs. It's the same feel as when I had a custom from UM a few years ago. Also the monitors are smaller in size than my other customs so it makes for a more slim profile fit.

Looking forward to your comparisons with the UERM. And, for that matter, HD800, too!

Scoot over guys I'm joining the club! These arrive 2 weeks ago and I got the chance to listen to them intensely since it coincided with my trip to Korea.
 
When I first put them on I remembered the time when I tried the universal demo of jh13, only with better fit and isolation. Soundwise I couldn't really recall how the demo sounded exactly but if there is difference i say it's minimal. 
JH13 really brings everything out from a recording, be it good traits or otherwise. For the first 50hours or so however I felt that this had a "too full" effect on me. I can't really describe it well but I think it's because there's so much details coupled with the intimate character of CIEM. Past 50 hours mark though either my ears have adapted to the sound or the burn in effect has kicked in, I'm really loving it! 
My home rig is hd800 paired with Woo WA5LE and I daresay the details on JH13 rivals even that! 
Only weakness compared to HD800 is obviously the soundstage. But this is the first time I'm thinking soundstage is not that important to overall sound quality. Heck I'm finding that in some songs I prefer JH13 than my home rig due to its intimate character. 
 
Not that I'm saying that JH13 can beat my home rig. For serious listening session I still reach for HD800 but if push comes to shove I'm thinking I can let go of my home rig setup and just live with JH13. This really is a fine gem which thanks to you all I had the guts to pull the trigger on and I'm not regretting every penny spent

The speed, detail retrieval and transparency of JH13 is truly staggering!

So far so good. This is turning out to be one of my best impulse buys in this hobby so far and trust me there have been many. Also the signature of my uerm seems closer than the jh13 to the HD800. One day I'm going to have write down my thoughts about my ciem and headphones.

Do you find yourself grabbing the JH13 vs the UERM for certain genres/albums over the other? And which do you think has the best timber? Thanks! 

 

[rawrster]

I'm not one that believes in genre specific for headphones. I can listen to anything in my library with any headphone I own. I go through phases where I use one headphone for weeks or months at a time and then go to another for some period of time.

I'm going to give the jh13 some more time before I go into specifics

I find that my listening preferences tend to vary based on what headphone I'm listening to. But maybe that is because I've been mostly limited lower budget iems/headphones. I've found relatively few great all rounders, though the W4R and HD600. But honestly, for me, the Achilles heel is string quartets or cello sonatas. Many iems and headphones have been discounted by me because they just can't pass the test of classical strings. So few in my price range ( up to $400 for headphone or iem) seem to do them really, really well.

The JH13 was an impulse buy?!  LOL.  I'm ever so jealous of your wallet, rawrster.
 
As far as the UERM/JH13 vs HD800 comparison.. I, too, found the UERM's signature closer to the HD800 than the JH13 was.  My UERM has had quite a bit of use over the past month or so.  It was quite bright and a bit soft in the bass region, ootb.  I did find the treble to noticeably smooth out after a good bit of use.. also the bass is punchier (but no less linear).  Considering those changes.. I find the UERM's signature to sit somewhere between the HD600 & HD800.  In other words, near perfection (for me).

I find both the UERM & JH13 to perform well, regardless of genre.  In terms of tonal accuracy, I find the UERM to barely pull ahead of the JH13.. mainly b/c of the JH13's (relative) warmth vs the UERM.  That being said, both these phones have among the purest timbre I've ever heard in a headphone.
 
One thing I have found, the UERM demands a very low output impedance source.  Something certainly less than 4 ohms (which my Galaxy S3 has).  The UERM sings off my iPhone 4.  I find this to be a very important consideration of you're looking at the UERM.  The JH13 also prefers an amp/DAP with low OI, but it doesn't seem quite as sensitive to this as the UERM is.

I really should stop going to NYC meets. My JH5, UERM and JH13 were all impulse buys. A JH Audio dealer was at a meet a few years ago where I bought the JH5. UE was at a NYC meet over the summer and ended up buying that. I was getting impressions for the V6 Stage and I asked to hear the JH13 and next thing I knew I was getting another set of impressions for the JH13. The only custom I own that hasn't been impulse is my V6 Stage and that's because I have to go through the whole process instead of having a dealer do it instead.
 
Also I'm responsible with my finances so I can do some impulse buys every once in a while. I'm approaching or at the point where I don't need anything else with headphones and iems and after the JH13 I don't see any destination that could be next and no Roxanne is not it.

Nice job on those headphones Anasztasia, they look awesome. Great design.

The only real "fault" I found with  JH13 was a lack or void of midbass.  You have this massive deep extending sub bass but then there is a void all the way up to the midrange.  Yes, it is intentional to add to the transparency but I found it a little off sounding.  The JH16 fills in the absent midbass yet still has tons of clarity and transparency.  It's just not off the charts like with JH13.  Great IEM though.  More unique sounding than JH16.  Sort of like JH5, JH16 and even my W3 are the same family type of sound sig but JH13 is a whole different beast.

The JH13 has plenty of mid bass to me. According to the GE graph in my accudio app, it is an approximate 5db peak centered at about 125hz. This is similar to how I hear it, especially compared to the UERM. I had estimated it was about 2db's more over the entire bass curve. See the green line in the screen capture below:

 

[goodvibes]

I thought they had a hair too much midbass when new followed by it being pretty neutral in that range after run in. To me, they sound like there's a bit extra low bass once settled in.
 
I personally don't fully agree with the accudio target curve which is the black line in this es5 graph. 

Accudio is also using a pre freq phase as their model (released with that curve in Aug 2012) and we don't know where sourced since Golden ear has never reviewed it though I did see a contributed graph from a member that shows a bump centered at around 60hz..
 
Here's an uncompensated curve of the jh13pro (again, pre freq phase)
Thes will vary by who does them etc but you'll never find one where the bass isn't rising below 125hz.
Here's another of the old jh13 (red line and compensated). Notice the high frequency coupling peak is at a different frequency so all need to be taken with a grain. FP should be smoother on top.

 
None of that makes a different opinion of it's bass character wrong as it's a bugger in IEMs since flat isn't flat sounding and even technical results will be dependent on opinion derived compensation curves.
