Finally, I've got NT-6 today!

Nozzle is silicon.

The sound is great.
Clear, extend, no artifacts! This sounds is very good for me. But this is my very initial impressions.

ETA was about one month.
 
Thank you very much average_joe!

 
Very nice!  I am very interested to know how the silicone nozzle is attached to the acrylic housing; can you take some closeup pictures and/or describe it?  Also, how do they sound

Please refer to the following pictures.

You can see seam of acrylic and silicon.
But very smooth transition.

This is not so soft. This silicon is similar in hardness to polyurethane rubber.
 
Advantage of this way is that sound tube is not flex.
So, SQ is same as normal acrylic nozzle, I think.

Very cool. Sinocelt and I were talking about this being a possibility but we were concerned about its durability, as the silicone can potentially slide off if too much friction is applied. Do you find that it gives better isolation that other acrylic customs?

Thanks for the additional photos.  I wonder if there is a special method for attaching the silicone to the shell (or is it vinyl like Westone?).

UE tried something like this and it didn't work out for them, and also Future Sonics offers silicone nozzles, but only warrants them for 3 months.  And I also recall discussing this topic with Sinocelt

I don't know how durable is this.
 
I think, this silicon is ShinEtsu KE-4898T or KE-42T (or other similar products) with primer-T for bonding.
Silicon rubber of prior to curing has very good adhesiveness to acrylic by using primer.
According to datasheet ( http://www.silicone.jp/e/catalog/pdf/rtv_e.pdf ) of silicon RTV rubber,
adhesion is 0.8MPa. This is enough value, I think.
 
They needs to be choice proper products and proper process of manufacture.

Good to hear about the properties, although the link isn't working for me (not that I would be able to read it!).  I am sure some company will get it right, and I hope that company is Hidition!  Westone did get it right with their vinyl tips, but that is a different material.

 

[michioga]

Sorry. I've corrected the mistake of link.

Joe,
Is this yours? NT6-Pro?

I also saw it! it look nice with the carbon.

michioga, is the silicone nozzle feels comfortable in your ear & is the isolation good?

Joe, the material description of the rubber is in english =)

Yes, I glanced it over but haven't had time to really look at it.  The proof will be in the product!

This nozzle feels very comfortable. But silicon feels to stick to skins. Of coerce, isolation is very good.

Good news! I'm looking forward to your precise and useful review!!
 
Good music!

Have you used any lubrication on the silicone?
 
Thank you, I am looking forward to the NT-6 pro.

Joe, you are the real driver of top tier custom IEM's sales. I have already bought SE-5 and now awaiting for your review of NT-6 Pro to choose one of Nt-6 series models.

Thanks, but all I do is try to describe what I hear and let people know how things compare.  It is the desire for the best sound that drives sales!

No, I haven't. I would venture to say my ear wax.
 
Sticking is only feeling.
Probably, we can use silicon every bit as acrylic.
