I really dig Soundfreaq speakers. In my opinion, they offer some of the best bang-for-your-buck you can get in the portable speaker market. And if you're on the hunt for a good ultra-portable speaker, you'd be hard-pressed to find something better than the Pocket Kick. It's a little-bitty thing that makes not little-bitty sound. In fact, I reviewed it a while back and did a comparison between it and the Jawbone Jambox Mini. No contest.
For the next week, you can grab this little guy for 24% off the normal price of $99 from StackSocial. (That's $75 for those who don't want to math...or read the headline.) It comes in black, gold, and platinum, so you even kind of have your choice of color. It also gets roughly 10 hours of battery life, so you don't have to worry about having to charge it after every use...unless that use lasts more than 10 hours.
