Gadget store Fancylogic sent as the Box2s Music Station portable MP3 Player stereo speakers for a quick review.

The Music Station has a folding design making it a small package to transport. Folded the speakers measure 110x60x60mm. Via the audio miniplug cable any mp3 or other music source can be connected. As you can see in the photos below most MP3 players can be put in the place in the middle of the speakers. The drawer is adjustable in depth to accommodate different players.
The portable speakers can either be powered with 4 AAA batteries or via DC 6V plug. The Music Station speakers come with a USB to DC cable to power the speakers via the USB port of a PC or notebook. The sound quality is good, not overwhelming but definitely usable. The output power is high enough to start a party. Verdict: It is not a Bose SoundDock, but then it is way cheaper and also works with any MP3 player. There are tons of low-cost portable speakers out there and this is one of them.
The Music Station speakers sell for $42.50 (batteries not included) on Fancylogic.
