So I must say I was a bit skeptical, because I could use only exclusively for the World Cup-port devices that adapter now. Previously, I had a universal USB adapter you could connect any type device. After my old Sony Walkman made muck with the store (s had already couple of years auf'm hump) I had put on me NEN new Sony Walkman, which with my old adapter but not to load was :-( After internet research I had read out that the seemingly unfortunately often happens with the Sony devices, so of course I was still skeptical whether it would be worthwhile to invest in a "no-name" products. Property me then but decided to me zuzulegen this adapter and must say I regret it in any way !!! My new WM invites with this device properly and even the old WM (which I thought of would simply oll and decrepit) is now back obediently and willingly :-) Therefore, all had similar problems: Try this adapter quiet time from 15 euros are then now not the world and definitely cheaper than what Sony offers on its website, especially since you also do not know that whether's the Better do or not, because Sony scheints simply nothing to do with any `:-)
