Great review. I don't have anything to add, other than I also really like the Quadbeat tips with these. If you can get your hands on some Auvio tips, those make them sound pretty amazing too. 

Nice review Peter.  The bass from these two earphones are still some of my favorites.  I like the comparisons also and would agree with you. 

Excellent Review!!!  Agree with everything!

Great review! How is the isolation of CKR9 compared to Havi?

Great Review Peter! I really like the comparison section as I feel I have a pretty good feel for the CKR9s now. I was under the impression that they are bright analytical iems but I am happy to see that I am wrong!
 
Also minor spelling mistake: Geek Out*

@RedJohn456 They're insanely detailed and crisp in the high mids and treble, and can be prone to fatigue with the stock tips, but tip rolling irons that problem right out. I can listen just fine with no fatigue using some wider tips. I think the narrower stock tips focus the upper mids and treble a bit too much, making some people hear them as bright. 

Thanks for the support guys, I really appreciate it!
 
@ozkan since they're a pretty shallow fit the choice of tips really has an impact on the isolation but with the same tips I'd  say that isolation on the two is pretty similar.
 
@RedJohn456 the Geek is fixed @ZapX629 is spot on in his description and also regarding the choice of tips.

Nice review!

Great review. The tips could be a little softer, but the isolation is quite good.

Great Review...is Amazon .com the only place to get them from. I am in the UK.

@smith Thomann.de were best priced and most reliable in UK when I bought mine. They deliver quick too.

Thanks guys!
 
@smith I got my pair from Asia but I also believe that Thomann is the best place to get them in Europe. I've bought other stuff from them in the past and have never experienced any trouble with them.
