Most high quality PSUs have some protection just in case they "POP" so I don't think any of your components were damaged.
Just RMA it, might have been a faulty unit off the production line.
I have the Plantronics 377 I got as a gift.
I also have the Beyerdynamic DTX 900 (which are close to the 377 price tag) and the DTX 900 are light years ahead.
The 777s are the 377s with USB.
Just get some Beyerdynamics, Audio Technica or Sennheiser, forget other "bling" brands.
You can get 2, we have 1500 rusting away.
We should invade someone.
