ive been using the case ever since i had a psp, and i love it. it also doubles as a stand as u can see in the pic.

the audio splitter is nice but useless for me
the earbuds have high quality neodymium drivers which should be clearly better than normal psp/ipod earbuds
id like a black wrist strap cause i have a white one now, i use it in dangerous situations when the psp might fall and i use it to grab the psp from my bag or pocket
the lcd cleaner is just a sort of cloth thing on a keychain like thing but it works

anyway, i bought the case for €10 alone, and you even get 2 sets of earbuds which is cool if you always share music but also if you don't, cause u can keep one at home and one hanging from ur psp or whatever and if it breaks you have another one :Pdon't forget its logitech, and the one thing they rock at besides input devices is sound
