Ever since I tried them at this Target some years ago, I've fallen in love with them. I could be getting them for my birthday soon, but I want to ask you guys some questions, and your opinion. -First off, I'm not sure about this, but, do these require separate batteries? Or are they special ones that come with it that I can recharge easily, or something like that? -Are there any other Bose Headphones you would recommend along the lines of the On-Ear? I'm not that big of an Around-Ear hps. -Any personal experience with them?
