Very nice detailed review thx

Congrats David, nice and detailled review, thanks

You should write more reviews. Spot on, and detailed.
Pleasure to read and reread again.

Thanks @all, I'll try to write reviews from now on, next will be the Solaris or IER-Z1R

Yes you should review more so you can get free stuff like many other reviewers

Its a travesty to give these iems just 4 stars. Do not agree with the new score, but we all have our opinions.

@Kitechaser Isn't that a strong word? 4 stars is not a bad rating, in retrospect the upper mids issue and lack of treble sparkle are no small items so it only show how good the CL2 are to get 4 stars despite that. Again those are unique sounding and pioneering closed back in small form factor.

Over the Vega? Check
Atlas? Check
AKt8ie? Check
Xelento? Check
Isine 20? Check
Lcdi4? Check or a tie
I don't know any other single driver iems that these do not compete with or are not outright better than.
All for 900 dollars.
All the iems I mentioned are rated 5 stars on this website.
The mids are a matter of taste, I enjoy them quite a lot, especially after upgrading cables.
The resolution, clarity and depth these iems create rivals some of the best multi BA iems.
