I purchased these speakers as a temporary option, as I expected to recieve some better quality ones for my birthday, however, these are such good quality for the price, I decided not to upgrade to a larger docking station. The sound quality is top notch and it's unbelieveable how easy these are to use. I own a 4th generation ipod nano, but these can also be used with a sony ericsson adapter. I can play my phone music also without purchasing seperate speakers, great!
The speakers are perfect to carry around, and the product is breathtaking value, having taken mine to the beach numerous times. Though the speakers are not the most expensive looking, they are top quality and well made - perfect. I highly reccomend these to anybody on a budget! :)
