Hi, got 3 question;

-Can the old Sony Wireless Headset that was released last year be used with PC and smartphones? If can, will the sound quality be the same as using it on PS3?
-Is it true, these wireless headset can interfere with wifi signal if your router is place too close to the TV and PS3?
-Anyone knows any shops in Klang Valley area that let me test these headsets first?

LOL !!! I HOPE SO .... now pocket money only got RM 200 .....

150 ill consider..

You heard right, it doesn't come with a USB charging cable unfortunately. And yes you need to buy 1 (must be USB to mini-USB) if you don't have it already, which you should since one comes with your PS3 to charge your controller.

Comfort is a subjective thing, since everyone has different head shapes and sizes.
For me personally, it is mostly comfortable except for the headband where I wish it would be a one piece construction instead of it being a 2 piece like it is now. I can bare with it though.
