Big sound from your buds-- earbuds, that is! These 500XL Desktop Speakers from Fred and Friends could not be cooler. Rather than displaying the same speakers everyone else has, choose to turn it up with home speakers that have a built-in amp! What's even better is, these iPhone speakers have 3-way power, so you can run them on batteries, a USB port, or an AC adapter. Your ears will thank you that you didn't skimp on sound with these 500XL Desktop Speakers!
