I have a bid on a pair of Ratphones on eBay they are the EX model, I should of checked them out more closely before I bid. This model doesn't have any volume control. I was wondering if there is any way to add a volume control to them. Hopefully someone will out bid me & I won't have to worry about it. I have always wanted a good set of headphones for my Tesoro Silver uMax. Thanks! Steve.
