Good to know!

Yeaaaah!

i have never tried a heat-sensitive custom but assume that the softer material is not as good with sound. that is my unstudied understanding of the matter. every rubber or foam i have tried with universals makes a poor echo sound that i cannot stand after a little while.

however, my acrylic customs are perfect as they tubes are very sturdy and don't soften to sound echos.

The sound tubes inside the IEM from the driver to the opening are the same, and the heat sensitive tips only contact the skin side, and are still fairly firm - just not rock hard. It's not like a soft tip absorbing sound.

Thanks for that, I appreciate you taking time to write impressions, and I can't wait for more feedback once you have the customs.

I don't like an emphasized treble; I think most headphones have an emphasized treble and things like the K1000 for instance sound jacked up in the highs to me. So what was the JH13's brightness like compared to some common full-sized headphones?

Also, if the JH13 really does extend out to 20khz, then this is going to be very, very imporant. This will will give it an edge when it comes to harmonics/overtones and its rendition of texture will be that much better.

Mostly what you lose over 15K is soundstage, "air", and "space". 18K is especially critical for the height/depth part of soundstage.

That said, most people over about 35 can't hear test tones over 16K. But I still believe that if those frequencies are missing, most well trained ears can hear the loss of soundstage and air.

So, IMO, frequencies up to 20K are essential for sound quality, especially when it comes to soundstage. This could be one of the reasons that full size cans with a wider frequency range sound "bigger".
Pardon me for asking, as you said that people over 35 might not be able to hear over 16khz, then how could the 18khz region let them experience a bigger soundstage? I read somewhere that although some frequencies are not audible, they still have effect on the brain, which leads to perception although the subject cannot hear anything. Is it this effect here? So i gather that the extended frequencies of the jh13 would let people hear a much more 3d sound? Am i right? Because soundstage is one important factor i consider before getting customs. How's the imaging capabilities? Does the extended frequency response make it better too?
Sorry, i've got lots of questions, i would like to make a direct leap from midfi to the top end, so i'm quite new to this.
Thanks for your replies.

Thanks HPA, that is really helpful.

I heard these at CanJam and while I thought they were the best IEMs I had ever heard overall (very huge soundstage for an IEM), the treble was too sibilant and the bass was overpowering for my ears. Jerry said he would tone down those frequencies by up to 3db (not more than that because he did not want to differentiate too much from the standard JH-13 sound signature). This could have been a byproduct of the foam tips we tried them out with, but Jerry said that probably wasn't the case. I have never liked foam tips with IEMs anyway, always preferred the silicone ones. I'm sure a custom fit would sound even better though. But if you want to feel your bass impact like nothing you've ever heard or felt before from a headphone, IEM or fullsize, this is the choice for you. It will knock your socks off.

Who would have ever thought it would be possible to stuff 6 drivers into an IEM?

Cool beans. If someone could do a review comparing side by side with UE11s, that'll be great!

this is totally incorrect i'm afraid. there are frequencies both below and above (moreso above) what would be considered audible that contribute to the harmonics and therefore most certainly do have an effect on the brain.

full customs would actually be fine in the gym as long as you didnt put them in and out while you were sweating profusely. you dont sweat deep in your earcanal and thats the only place there is an opening. all the same some caution should probably be taken and maybe a cheaper pair for working out would be wise.

So, may i ask, does this fact alone have a significant impact on the soundstaging capabilities of a custom resulting in a more 3d sound? Or does the other factors like the circuitry in the custom or the placement of the drivers affect soundstage more? What i'm asking is customs in general and not just directed at the jh13pro

Thanks

I have just shipped my ear molds to Jerry, now the big wait begins.

good to hear I am happy to see that those balanced armatures are putting out some nice impactful bass but the foam tips they use for universals always play the bass up so I am expecting a little less on the final product and the treble will likely be more clear as well since those comply tips tend to have that weird effect.

I'm waiting for my audiologist to call me back to confirm quote on impressions and then I'm harassing them to get me in today. Must get in soon!

actually I find that foam tips not so much play up the bass, but just make it seem more boomy - and if they don't seal so well, the bass will be lost anyway.
