This in no way helps with the OP's question, but I have come to the conclusion that there isn't a One Model Fits All for headphones. Each of us has a lifetime of different hearing damage in various frequency ranges in addition to how good our hearing is genetically speaking. Certainly, there are some headphones that are better quality than others or have a feature (eg, waterproof, unique connector, etc) that sets them apart, but ideally, you'd want to try out each headphones to see how well they fit and perform for YOU. Since that is rarely practical, we all just end up doing what this thread is about: asking experienced users for their opinion/evaluation. And there's certainly nothing wrong with that.
On my CTX, I have used stock Koss (great soft fit for me, but others don't like the fit), Sony audio headphones I had sitting around, Grey Ghosts, and even iphone earbuds with an adaptor. Other than sound level from how tightly the buds fit, I don't really notice a difference in detecting targets. But again, that's Me and it may not be the same for You.
I will say that I cursed the Koss 30's mightly when the plug shorted out, but ML promptly sent me another pair on just my say so. Even said keep the old pair. I promptly replaced the plug with a high quality one and haven't had a problem with them since.
