Updated yesterday. VZ's update came in two parts. First part updated fine, but the second part give me issues, so I did an FDR between the two (nervously, I might add.) After the second update finally installed correctly, things have been really good. Battery is way better and unit overall is very snappy. Saw your post and gave the headphones a try and they worked as expected. Plugged them in and PowerAmp cranked up and started playing from my library. When I unplugged them, same thing, it worked as expected. An FDR may be in your future.
