Portable Music For Audiophiles: Digizoid ZO Personal Subwoofer

Everything has pretty much shrunk in the world of electronics. So why not subwoofers? Now they have, with the DigiZoid ZO Personal Subwoofer, a pocket-sized device that will give your portable music that booming quality you've been waiting your whole life for.

According to Digizoid, their creation defines a new category of sound system - the electronic subwoofer. A novel gadget, it brings something new for audiophiles who want the best sound experience even while on the road. It reshapes your earphone's frequency response (to improve sound reproduction through the entire audio spectrum), performs dynamic signal adjustments, dampens digitally-induced noise, applies frequency-dependent time delay to subtly separate tones (to improve realism) and offers a selection of 32 sound-balancing profiles (which you can change at the flick of a switch).

The Zo comes in a sleek-looking compact case, measuring 2.75 x 1.5 x 0.38 inches (h x w x d). It uses 3.5mm slots for input and output, and is compatible with most any sound devices (such as iPods, MP3 players, cellphones and laptops for input; headphones, earbuds, speakers and car stereos for output), provided they have the corresponding connectors. Battery is rechargeable and can support up to 12 hours of playback. In case the device dies while you're still on the road, no need to pull out the jacks either - it will just pass the audio from the source to the output with no extra processing.

Sure, it adds another extra gadget to carry in your pocket. If you're serious about good music, though, the Digizoid ZO Personal Subwoofer is an affordable addition to your portable entertainment suite at only $99.
