Ah yeah the original T1.2 I had sounded more like a DT 880 based on memory at least, an analytical neutral/bright sound. The blacks were more laid-back in the upper mids and lower treble and had more notably more mid-bass, the blacks reminded me a bit of the Amiron Home but warmer mids, smoother/darker treble, and less sub-bass/more mid-bass. The gen 3 on the other hand sounds meaty and powerful.Thanks - that's exactly how they sound. My last T1s were also black ones and sounded much smoother. Seems like I should have kept them.
