Too much mid-bass and treble roll-off. Too much warmth for my tastes. Wasn't crazy about the sticky cable either. But I heard that the black version clears all that up. Guess I'll see.
For other TOTL, you can never go wrong with Cypherus buds. Avoid QFred, since they have the same sound signature (though I prefer these over Zen 2.0 regular). Other buds like Diomnes have really limited stock, so they are hard to get (I was lucky on snagging a Lv2). You can check the list in my signature for impressions on buds I've heard. It's pending a 2.0 update though lol.
I agree on the cable and your perception of the Zen 2.0 in general. I believe it does change a bit with burn-in, but it is not going to change all that much. I HATE the cable. I'm probably going to swap it for an SPC one, which should help a bit with the thickness and increase the upper mids and treble as well. Will see. I wouldn't mind a different color housing either. The cable on the black is crazy stiff though. I think it is a silly move not to include at least an "o" ring as a slider. I'll probably source one of those as well and undo the XLR that mine is terminated with to slide that on.
