THE BOOM MEMORY 4GB

The BOOM also features nice aluminum housing but it's somewhat larger than the POWER model measuring 75mm in length, 49mm in width and 52mm in height with a weight of 153g.

One 40mm driver is placed on each side to produce a stereo effect (however due to battery limitations these two are not much louder than the one of the POWER model).

At the front we see the playback buttons (the next/previous track buttons also double as the volume control ones).

The Micro SD/TF card slot, micro-USB port, 3.5mm headphones port and the power on/off switch are placed at the rear.

Here we have placed both the POWER and BOOM portable speakers right next to the NuForce Cube, the Sandberg Pocket Bluetooth Speaker and the BeatBlock Premium Wireless Speaker by Tech-Life to see exactly how large they are.

The RockDoc BOOM also has a nice blue pulsating LED underneath for when the speaker is being used (unfortunately you can't turn it off).
