Don't be tempted by cool design
These are honestly the worst ipod speakers I have ever heard. The design is very sleek and stylish but the sound quality is incredibly poor. When the volume is anywhere past minimum there is a very audible crackling sound and the top volume is no more than that of an inbuilt mobile phone speaker. With my ipod touch the speakers also pause every 30 seconds or so as the ipod slips out of position due to the dock's attractive but inpractical design.
I can not emphasise enough how poor these "speakers" are. Do NOT be tempted by the design and reduction, you will regret it.
Hope this is helpful...
