Right? I often prefer the X10s to my TF10s, quite often. If you don't mind EQ, try giving them about a 2-4 dB boost at 1 khz, 5.5 khz, and somewhere high, 10k or 11.5k, it makes them sound much more balanced (but obviously still not neutral). I tried lowering the bass at first but the sound is so colored overall that it doesn't do much. But putting some small, broad peaks in the rest of the spectrum evens them out and produces an even more engaging sound with noticeably better vocals IMO.
I rarely reached for the TF10 when I had my SM3s, but the X10s have a really unique, lush, and powerful sound unlike any BA I have ever heard and I always find them back in my ears. With some of my more textured electronic music like Shpongle and Infected Mushroom, they make the TF10 sound downright hollow. They EQ better than the TF10 too, although they are not as fast and detailed and the treble will never compare regardless of EQ. I think the X10 compete well with, and also compliment the TF10.
