As part of the Matador Twitter contest, we will be spotlighting cool gear we’ll be giving away to lucky readers.

One of the sleekest portable speakers out on the market, the iMainGo2 not only provides high quality “room-flooding” sound when hooked to your MP3 player, its hard casing helps protect it too.

Other nifty features include:

* Premium titanium high output stereo speakers
* Tuned porting for amazing bass reproduction
* Ultra-efficient digital music amplifier
* Battery life up to 30 hours
* Includes 4 AAA Energizer alkaline batteries and a removable strap

In addition to iPods, it also supports other media players such as Zunes and iPhones, and can be used as an external sound system for cellphones, laptops, electric guitars, and a host of other portable devices.

Readily available for purchase at Eastern Mountain Sports, Target, Amazon.com, and of course, its official website.

And the best part? We’re giving away four (4) copies of the iMainGo2 Speaker!

Disclaimer – This particular giveaway is limited to only US-based readers.
