Anyone using the HBH-PV700?

Posted by dckl
I was just browsing the SE online store when I came across the HBH-PV700. The short description claims it "incorporates the new system connector Fast port," which would be great since I'm getting the Z520, and don't have to deal with 2 seperate chargers, plus my HBH-30 is slowly falling apart as I type.

Anyway, does anyone have the HBH-PV700? If so, how's the sound on either ends, especially around busy/loud places. I'd rather the HBH-610 with its digital echo cancellation and noise reduction, but as i mentioned, I really would rather have one charger that does it all.

Thanks!
