Although the ED11 look almost the same as ED10, both the timbre and the sound signature are different. While ED10 has relatively clear mids and comfortable highs, the ED11 seem to have some of GR's harshness. It might have more to do with KZ's awful quality assurance when it comes to driver-matching and consistency within the same model, but I wouldn't be too sure.

Comfort & Fit
One of the most comfortable earphones to wear, thanks to the housing design. The housing pushes back against your ear slightly to keep the earphones inside your ears. The noise cancellation is wonderful thanks to the perfect seal. But if the nice whirlwind M-size tips don't fit your ears and you dislike the generic tips, you're in trouble, and you'll have to order S and L-size whirlwind tips separately, like I did.
Lows / Bass
The bass is well present and deep, and you can hear plenty of sub-bass rumble in electronic music content.
Mids / Vocals
Loud but has no clarity. Inaccurate tone with a lot of sibilance.
Highs / Treble
Sibilant and inaccurate. Not like GR but still very fatiguing.
