Hmm if you can try them out you definitely should before purchasing. I actually feel that the bass is a tad bit too powerful and bleeds a little into the other spectrums on some songs. But on certain electronic/dance songs where the 'beat' is the main attraction, the Super darts really shine.
Atomic Floyd themselves describe the sound signature as a pronounced V shape. I can tell you this at least is true
Feel free to pm me if you have further qs
