I bought a set of these speakers last week for my daughters MP3 player - excellent sound quality from these speakers!
Most online sites selling for between £16.00 and £20.00. PC World offer just under £10 discount on store price (reduced from £24.45 to £14.67) if you order online and select "collect from store" option. Makes it convenient to pick up from local PC World!
Great 2.0 PC/MP3 speakers - just take a look at the Ebuyer customer reviews.
