Editor's note: The rating of the MobilBlu B2 has been lowered from 5.7 to 5 because of the appalling battery life discovered during CNET Labs' testing.
The last MobiBlu MP3 players to grace the CNET Reviews desk--the US2 and the Cube2--scored very well with the editors, thanks to innovative designs and useful features. More than a year later, we got our hands on MobiBlu's latest device for the States, the B2. Currently available with 2GB of flash memory for $99, the B2 suffers from an unimpressive design and some crippled features. However, the player still offers some worthwhile extras and reasonable sound quality.
At 2.8 inches wide by 2 inches tall by 0.4 inch thick, the MobiBlu B2 is unquestionably compact and that makes its 2.3-inch color OLED display large by comparison. Since the screen dominates the face of the device, all of the controls and ports reside around the edges. The top side has a standard 3.5mm headphone jack, a record button, and keys for shuttling through tracks and starting and stopping playback. The bottom spine houses the standard mini USB port (for charging/syncing), a power/hold switch (though no markings indicate this), volume keys, and a menu button. All in all, the placement of the controls related to the headphone port makes the device sort of awkward to hold. In fact, several buttons are so close together, it makes them somewhat difficult to use. Not a deal breaker, but something to consider.
