Bass adjusted to 3 o'clock position, sounds amazing :)

Do you have an idea of what the bass levels are for 12 oclock, 3 oclock, etc?

You seem to be very knowledgable about hifi audio equipment, at least with IEMs in that case.

As you may probably know people talk of burn-in when it comes to speakers, does this exclusively apply to dynamic drivers or BA drivers also? Anyway to the point, the head-fi community seems to be very optimistic when discussing burn in and always anticipating the speakers to improve.. Why would burn in necessarily improve sound quality when surely it could swing both ways?

Besides that, I have my mind made up now already since it appears to me that JH is the only one doing freqphase which apparently works wonders (joker's review). Speaking of his review he rated the JH13 a 10 for sound. So I'm assuming that the return in sound quality of the Roxanne for what you pay extra (which is quite substantial to say the least) is negligible. I don't see how they would perform much better than the 13, presumably just a different sound signature and minor improvement in clarity, if any for that matter.

Actually curious about this - my understanding is FP was an improvement to JH's own designs, by measuring phase alignment and consequently making improvements to those designs for better coherence.

 

But does that necessarily mean freqphase is some sort of tech that JH has and others don't, or is it a marketing term at this point?  

 

An example I can think of is Apple's 'Retina' display, which was amazing when it came out, but shortly after had competitors exceeding the DPI.

Oh, there are plenty of people more knowledgeable than I, on Head-fi :smile:(thank goodness! LOL!)

 

This isn't the right place to discuss 'burn-in', but if you search this thread, you will find a brief discussion of it, or much more substantial discussions in the 'Sound Science' part of the forums.

There are a lot of factors in burn in, and not all can be explained in detail here.

Freqphase seems to be have an effect as well on the "speed" of how the music reaches your ear, and is currently only used by JH.

The 13 and Roxanne are both different beasts and it will depend on you if you will like it for yourself or not. We who have reviewed CIEMs and IEMs constantly state, we can only give what we hear and everything is always up to you smily_headphones1.gif

I think the "freqphase" is some kind of timing in which the sound reaches you eardrum.

In this case, JH uses various different lengths of acoustic tube so that the sound reaches your eardrum at the exact same time.

Correct me if I'm wrong though, this is just a speculation.

Thank you both for the feedback. FYI I was referring to both the input connector and the shell of the IEM, I did not realise that the material is specifically chosen because of its comfortability properties and did not think of this, I thought it was done to cut down costs. Now I can respect IEMs for what they are and not overpriced clumps of plastic! But with the astonishing 5-way crossover from spiral ears which is unheard of, it looks like JH have some tough competition.

Furthermore, now that they have implemented freqphase, how does the soundstage compare to the HD800 generally speaking for the line of IEMs (Jh 13, 16 & Rox)? In reviews I have heard that apparently they have spectacular soundstage. If that is true then it is truly fascinating, JH has reached the pinnacle of true quality sound, innovation is just something else!

The soundstage on the Roxanne is present and you I can definitely hear it and visualize it. I think that the shear number of drivers is helping to give greater definition to what I am hearing.  The HD800 being over ear and open has a much larger stage, and around the head feeling.  The Roxanne's are more central and tighter stage, but it is there.  Hard to describe, it is something you need to listen to yourself to get he full impression.

For the freqphase answer look here:

I also read that they use internal tubes or 'waveguides' to get the timing right from the triple bores...FWIW

Let me put it another way - is there evidence that other makers aren't doing such measurements and taking phase factors into account in their designs?

I would guess that they are at the least considering it, hence the requirement for having proper impressions to place the outlets of the ports in the right place in the ear canal.  Now to what extent they are looking at it, I would have no clue...

Maybe. If others are doing it but not saying they are (which I doubt), blame their marking department. :o

Just got my.. Seem like CF is really hard to make, not impressive with the finishing. I had dismantle my AK120, can't compare the impression I have now vs impression I have form Mook.

Just a question.
Did you specifically ask for the clear cable?
Thanks

I do not understand. This is not CF so what do you mean. Congrats anyways.
