Straight outta Korea is the MPker, a mobile phone speaker set that packs a nice little punch and has a sexy silver design. The MPker starts off more like a flat rectangle then expands to reveal the dock and speakers. It fits what looks like Samsung phones and some other models as well. Controls are available right underneath the dock so you're not sitting there fumbling with the phone's dinky buttons. The price for this speaker set is excellent as well, as it'll only set you back $34.
