I do, actually. Punchier...more dynamic. Hard to say if there's any more detail/clarity...may just be placebo. Either way, this current setup is more than enough to keep me happy as a portable solution. Listening with the DT1350.
Funny how preferences vary. The size was the only thing holding me back from getting this phone. I thought phablets were absurd and swore I'd never own one. Just yesterday, after owning the phone for about a month, I was telling my wife how completely normal and natural it felt. It's hard to imagine going back to a normal sized phone now. Pretty shocking to me, really.
This is all really interesting. When the 400i/560 was first released, HFM swore up and down that the headbands weren't compatible with their old line.
Either they were lying to us then to encourage us to by their new line or this particular salesman has no clue what he/she is talking about.
