That looks too complicated for what it is. The ones I got have the mount built into the tips instead of a 2 step system

Sorry, but don't have a link. I got it in China when I was there.

got it from a store in China called menthon These is at least a couple variations of these kind of foam tips. The ones I got are similar to the comply. There is also the sponge type like these but I wasnt too keen on them.

Had my Airpods Pro since launch and love them. Just got these foam tips and they improved the isolation significantly and also increased the bass as well. I normally wear S in the stock silicone but had to upsize to M in these. I used these a lot on the trans atlantic airplane trips and on...

After spending some time (almost a year) with my InEarz remolded PFE and UM remolded TF10x6, I can say that I like the fit from InEarz better and they seem to provide a higher quality of finished product. You can see some impurities in the mold from UM but the remold I got from InEarz is perfect. 

I think it has to do with the Fit. I think the irritation had an effect on sonic perception. Just like how soundstage changes with different tips on an universal IEM.   I think my ears have settled and got used to customs now

Here's an update   The irritation has subsided, I've been alternating these with my TF10x6 by UM.   I find that the highs are less fatigueing but it sounds more like the PFE that I use to have but with a wider sound stage and better isolation. I went back and forth with the filters and stuck...

Got my TF10x6   definitely a good step up from the TF10, the sound stage is what hit me first, it was wider than stock. The mids are so much more intimate and detailed, Bass is more Dynamic. Well worth the $$.. I'm using an Oyaide Cable with mine.

Another update   I think I managed to get the fit right, but I'll give it another few days to test.   For some reason, I find the sound brighter than what it was before. Not sure if it's the new Nexus 5 that I'm using as the source, Fiio RC WT1 Cable or the reshelled IEMs. It has gotten...

  Here's the picture I posted earlier on     they reused the nozzle tip from the PFE, so you can change filters just like how you would on the stock PFE. The filters won't fall out.

Listening to my remolded PFE111 as I'm typing.   I'm really surprised at how they kept the acoustic filters interchangeable, so kudos to them for making it work. I was expecting them to permanently mold the filters inside.   Sound wise, it still has that nice mid range the PFE offers with...

they are ready for shipping   Can't wait to receive them, they look amazing from the pics (from their facebook), InEarz have came a long way and I can say their finish and shine rivals other top tier CIEM manufacturers. I'll post impressions of them as soon as I receive them.

I sent my PFE111 for remold and they are complete. Just waiting for having them shipped back.   I asked Kaysen on whether they can do PFEs and for sure they can. They will also permanently mold the acoustic filter into the shell.

Hi Stephen,    I appreciate your reply. Do you have an associate in China right now that I can contact? I'm heading to Shanghai in two days and would like to get the order rolling. I'll be doing my impressions in Shanghai and will be shipping from there.   If you don't mind, please take a...

how long does it take for Guo to respond usually?
