Sound Bag makes for portable audio sharing

Portable speakers aren’t exactly thumping when it comes to sharing your music within a group, hence Dobson decided to take things into his own hands by placing speakers within a backpack, calling it the Sound Bag. What you get would be a couple of large speakers that are powered by a 50W amplifier which in turn is powered by a 7000mAh battery that is able to last anywhere from 15 to 20 hours of continuous audio playback. You can be sure to attract a small crowd if you decide to busk with this on the streets, where the loud noise thrown ought to accentuate your fine voice and mad guitar playing skills.
