The DSP is factory tuned, you probably need some engineering skills to be able to make it sound good with any other set, because it will sound bad.

Erm no. The DSP is surely 'tuned' to the frequency response of the IEMs to EQ it. This will sound bad on any other set than this

If they haven't fixed:

• Channel imbalance
• Filters falling out
• The sticky cable (non detachable is fine if the cable is good, but it's not)
• The shitty ergonomics that undo the sealing ( the ear hooks are horrible) ... Then I'm not buying it. The Chus are sitting on my desk while I'm going out with the CCA CRA outside just fine ( it has shitty ergonomics too but eh), just because the Chus become unusable after 30minutes outside.
