Hi! The stock headset isn't working for me, because of huge earpiece and no controls for music. Original SE headsets are too expensive. I tried headset from nokia 5800 but it doesn't work.The only one working are ones with mic and answer button. So I found something like this http://cgi.ebay.co.uk/L344B-Stereo-Headphone-Remote-Control-PSP-Slim-2000-/310270350204?pt=UK_VideoGames_VideoGameAccessories_VideoGameAccessories_JN&hash=item483d8dd37c#ht_2273wt_1139 I noticed that the phone has some extension right beside 3.5mm jack so I'm wondering if this one is that and will it work? Thnx!
