Just got a QP1R this past weekend. I've been comparing it to the ZX2 over the past several days, and sonically it's crazy how much more open and dynamic it is than the Sony (and this is with the ZX2 running the increased volume output trick, which gives it more clarity and range). I really did not expect that. I find it hard to choose between them though because with how great the Questyle is with its sound, the Sony is that good aesthetically (and the QP1R is that much worse, with floppy scroll wheel and inaccurate volume knob). I'm at a crossroads literally as I don't want to keep both. Battery life seems to be a good bit better than the claimed 10 hours... however I haven't taken detailed run times to this point. But it's been going solid a couple hours per day since picking it up on Saturday, and it's only showing down to 50%. Not bad.
Man o' man, the SOUND though! Jeez. My UM Mason universals are just singing (notoriously hard to drive)...
