Mad Dogs won't work for portability reasons. I mean I am planning to use them portable first hand and I am not gonna spending some money on portable gear any time soon.
900X can be powered by my lowly Clip+. Mad Dogs, on the other hand... no way, right?
They are just releasing the Alpha Dogs which are an improvement to them but are way above my budget.
That said, I'd love to hear the Mad Dogs some day, but probably not now... Would be a waste IMO :/
they actually sound ok out of the sansa clip zip but you have to have the volume at max.
