Hello erybody.

I'm am the proud new owner of a very clean looking Sony Walkman WM-F100III. I can only say looking at the moment because it did not come with a battery case, for aa or the HQRP size. I'm wondering what exactly the batter case is called. I found the manual which gave the item number EBP-10 as the optional battery case, so i went to ebay and bought this, but i'm not sure this is going to work. Any ideas? Thank you.

Looks like it should work.
