Jam Plus Speaker: Enjoy your favorite music with this portable speaker, which features Bluetooth technology, so you can wirelessly stream music and more from your enabled device up to 30' away. The rechargeable battery ensures on-the-go power.
I bought mine a week ago and I take them EVERYWHERE.
I ride my bike to work and around town so I keep my pair in netting on my backpack. The speaker can get REALLY loud and it doesn't distort when you crank it up.
It also uses true stereo when 2 are paired, one gets the left chan while the other gets the right, it's not just duplicating the audio stream to both speakers. The linking process is simple with minimal effort required to get them to work. Since one sounds great, two is AMAZING!
COMPLETELY worth the money.
My only real gripe is the USB charge cable that is included is under 6 inches long. However most people have extra Micro USB chargers to use anyway.

What's great about it: Audio is VERY clear and has more bass than the regular Jam can. You can link 2 together.
What's not so great: Can only link 2 of them. Really short recharge cable included in package.
