Query: Stunning sound for this price!

I've enjoyed Panasonic quality since I was a child. These headphones are stunning. I've owned several pairs of "lightweight" phones over the years, -but these are exceptional -especially as open-air designs. I've now purchased several for friends. I'm also a Sony MDR-V6 enthusiast (& that should tell you about my taste for exceptional phones). I'm generally not easily impressed. These Panasonic phones were a pleasing exception! If Panasonic marketing is reading; --They'd be well advised to make these phones into a similar model with a boom-microphone for skype-type communications.
