content: I use bluetooth headphones, and they work fine... mostly. There are areas in the city (I live in Sydney) where the headphone will start to skip every time. Not sure what causes it, it may be too many WIFI hotspots in the area, but is a surefire thing. I must carry the phone in my hand somewhat close to my head to get a stable connection when I walk through those areas. I have to add, I do carry a set of emergency wired Sennheiser earbuds for that off occasion where I forget to charge and the headphones die on me mid train commute (the horror!)
