Beyer fanboy, very happy with my DTX 100's. One thing that could be improved though is the noise isolation of the buds: with the DTX 100's, I still hear a lot of outside noise seeping through. (Much more than with the HiFiMan RE0's, for example.) I hope that's improved in this version.
Apart from that: way to go, Beyer! Looking forward to hearing the new DTX 101 iE's.
