On my 2nd pair of Sennhieser and it appears yet again that the left side of them is losing audio. Was curious to know if the PSP (3000 to be exact) can use wireless headphones. Issues with wireless headphones? I presume it's the PSP GO that can only use bluetooth. Can the Vita? If I eventually get it (after a price drop and a color I want) I'd be curious to know how it handles music compared to the PSP.
