So have you heard a top-tier custom?   Because it sounds like you haven't and then everything you say is meaningless.      By its very nature the value of customs can only be judged by their owners. If it's so popular, clearly there's a substantial market for which the product is not...

Thread isn't about single versus multi driver.   On topic: I like to share. You can poison people with universals. With customs people are just like what is that thing in your ear and you go oh this sounds really good but you have to take my word for it and they're like oooookay. 

The rough idea is there in the google translate, for once. It'll probably be a December release, 40000 yen, positioned as an upgrade to the e-Q7, and the sound is more open/refined than the e-Q7 especially in the mids and highs while being easy to drive, with a wider soundstage and improved...

  You know what, I just replaced my pair a few days ago with a brand new set and there is indeed a "crease". The cable also behaves in a way that's slightly different from my old pair, though that could just be because it's new. I don't think there's a sonic difference though. 

  Just to say, it's really worth it to obtain a high quality music library. I do listen to similar genres as you and trust me, the difference between the average youtube-rip quality versus even a 320kbps mp3 (converted from lossless) can be pretty massive, especially listening from competent gear. 

W4R is simply very good - I don't think it's very exciting, but exciting all the time becomes tiring.   CK100pro on the other hand can be very exciting - fast stuff sound amazing on it because of the explosion of details and the crispness of the whole signature, and yet it's not fatiguing...

What was with the headfonia blog talking about all these changes in the sound? All imaginary? I was so excited for an upgraded W4 too.

Thanks for the review. The 100pros are amazing indeed.

SO excited for this. Doesn't seem like the cable got massive improvements, but damn if I'm not eager for an upgrade. 

They are actually fairly durable for how fragile the connection seems to look. Mine lasted over a year with very rough use before one side started having connection issues (it's probably from the cable split), but I can still fix it by twisting the cable one way/not moving about when using the...

Second the CK100Pro, natural upgrade to the CK10 signature and very wide genre bandwidth, just a top top tier IEM overall (though sadly very under-appreciated around these parts). 

Sound stage on the CK100pro is not amazingly huge, but definitely spacious and sufficient for most genres, response is fairly flat and extension is outstanding. I also find them ok to wear, it seems awkward but really isn't once you get used to it. These are very underrated top tier iems IMO.

They were pretty good when I had an audition. Maybe not exactly the best value with the premium pricing, but certainly a good upper-tier IEM. Maybe your pair or fit was problematic.

No experience with the Heir, but currently own the CK100pro. It's pretty much near the top of the universals food chain in terms of technical ability - transparency, detail, speed, soundstage, all reference-class. Not really lacking in any sound department (bass is clean, quick and decently...

Audio-Technica's CK100pro comes to mind. One of the very few universals I'll put in the same breath as EX1000, very similar signature but much better ergonomics and isolation.
