I sold the u12t because I didn't listen to them very much anymore, same with the m11 DAP I hooked them up to - I guess the wireless B&W PX8 sort of replaced them out of sheer convenience. I just got a set of Raptgo Hook X today that I consider to be very good for 1/10th the price of the u12t, but I plan on making it wireless with a bluetooth dongle also. I hate wires on mobile systems because I always get them caught on something and they get ripped out of my ears. I wouldn't say I like the u12ts more than the Utopias, more like I like them as much as the Utopias for 1/3 - 1/4 the price. They sounded just as good, but were far cheaper. That said, I found the Utopias to be very neutral, detailed, and boring, and I replaced them with the HE-1000 v2 (which Crinacle loves) and I replaced those with the RAD-0 (which Crinacle hates.) So, maybe I'm not a good source haha. If you enjoy your u12ts, keep them - I haven't heard an IEM better than them, though for 1/10 the price, the Raptgo Hook is impressing me.
