Maybe? Haha!

Also on the inside of the case there are several finger prints of dried glue on the bottom of the case.  Likely from glue on the fingers when gluing the clear plastic "negative" holders to the carbon fiber.  Also some shoddy glue work done on this part as well ruining an area of the carbon fiber finish.

 

How do they sound?  Off the bat very dark and muffled.  Using the same source as I did to audition them at Can Jam.  Sound nothing alike.  Assuming they just need some break in.  I remember my JH11Pros sounding terrible when I first got them as well.  Will reserve judement on the sound for several days.

 

 

If the smudge was anywhere else, I'd live with it if happy otherwise but those look like they need to go back.:frown:

Make sure that tipping them one way or another doesn't present more highs before you do. They can correct bore position as well if needed. I only mention it because you said they may be a bit dark but then again, it took a bit for my 13s to open up as well. Connector looks very durable.

I'm drawing a few initial impressions here, its definitely a darker sound than the 13s, with the highs just a little bit laid back. Bass is, of course, variant. When I first popped them in they were set to full bass, and I immediately toned it down to around the 10 o'clock area, where there's enough bass and enough detail in the highs (the sound seemed like the highs were pushed back by the bass) that made me enjoy. I do immediately note that they're not as warm as the Kaiser 10s (which are amazing for vocals), but they're more accurate and probably a bit more honest as well. As I noted in my preliminary notes on the Kaiser 10 they're balanced but not neutral. The Roxannes are more in the area of neutral while the balance is probably up to the guy tuning them. I'm going to spend a few more days with them and come back to you guys.

Thank you very much. I found your post very on point and you know what you really hearing. Not like typical ciem buyers. Now I can grab some useful imformation from your posts about k10 and Roxanne. . So am I right to say in terms of brightness jh13>Roxanne>k10?

Cheers

Send them back..not ten bob a job headphones..an expensive set of in ear monitors.. p.s has anyone tried these with the AK120 Titan?

They well pretty good with an ak120, titan should be no different.

the fact they sent it with a finger print like this is a joke itself, are they blind? this epic jewel worth 1800$ .... not cool from them at all....

I'm not suggesting it's 'OK' to dispatch an item like this. I'm really not.

 

However, I suspect that the CF shells are made using an epoxy resin rather than acrylic.

 

If  I am correct, then that puts things into perspective.

 

Generally, when epoxy is cured, it is either done so in ambient temperature (in which case, depending on the desired specification of the resin, it may have a cure time of between approximately 2 - 24 hours), or it may be cured in an autoclave.

 

I very much doubt JHA would be using the autoclave method.

 

So, if they are, indeed, using epoxy resin, and if they are curing it in ambient conditions, then this means what? Well, I do have some firsthand experience in use of wet lay-up composite techniques, from my days designing and building high performance radio controlled model aircraft. Something one quickly learns about epoxy resins is that although they may, to the touch, appear to be 'fully cured' within the specified curing period, the resin may not actually achieve it's final degree of hardness until several days later.

 

...and until that final degree of hardness has been attained, it is not wise to attempt to polish imperfections from the surface, as one tends to end up with a cloudy/milky appearance rather than a clean transparent polished appearance, since the abraded particles can be unintentionally deposited into the resin surface rather than removed from it.

 

It's also fair to point out that working with composites is very skilled and demanding work. I've previously remarked that I am surprised at JHAs courage to undertake composite work on such a tiny, intricate shape as a CIEM shell. I seriously think people would be astonished if they tried to accomplish the task themselves - it is really skilled work. The materials do not happily go wherever you want them - they have a 'mind of their own', to some extent, and it can be a battle to get them to remain precisely in situ, even with modern specialist carbon weaves, and then there's the troublesome mess of handling resins (and their uncatalysed surplus) in their uncured state... but I think you get the picture...  So, yes, it is fair for someone who has paid $200 bucks extra, to expect a high standard of finish, with no fingerprints, but, equally, one should not be too quick to pass judgment until one has personally experienced how incredibly challenging it is to work with wet lay-up composite techniques.

 

Again, I am not trying to excuse the oversight that that CIEM has been cleared for dispatch with a huge fingerprint in the resin, but I can see that under extremely tight time constraints, with some customers baying for blood, JHA would not necessarily have been able to buff the imperfection out of the resin unless they delayed dispatch for a few days later.

 

That's not an easy decision to make when there are customers publicly berating the company for slow dispatch times.

 

Make of the above what you will, and I totally understand if you feel they should not have dispatched CIEMs in that state. I'm just offering potential extenuating circumstances that might, perhaps, explain how the situation may have arisen. I have absolutely no personal allegiance to JHA (as should be apparent from my previous contentious remarks about their marketing approach), but I do know what it's like to manually produce products under extremely tight deadlines, and there are invariably a number of priorities being juggled, under circumstances of substantial stress, in order to achieve a final outcome. Under such circumstances, it is not always possible to fully satisfy every single one of those priorities.

 

I am also confident that JHA will rectify that fingerprint issue. If I had that pair of CIEMs, I'd immediately contact JHA to let them know I require the issue to be rectified, but continue to enjoy listening to them for a few weeks, while JHA clear their backlog, and then send them back for a re-finish once things have calmed down at JHAs lab.

Completely agree, the guy paid $200 extra for a CF finish, not a finger print finish. Pathetic.

I think that they are in that much of a high demand with such a large back log of orders that they are just letting them go out without being checked over(it's Christmas time ish holidays an all)..probably just put in the box with glue on fingers!

The owner said it wasn't in the top coat so Mython's explanation works. Certainly something to get corrected but definitely not put in box with glue on fingers.
