OEM OrigAudio Universal Portable Rock-It 2 Vibration Speaker 3.5mm - Black
This is the second one I've bought<br />Bought it for a guy at work after he saw mine<br />I'm a union construction worker and radios are almost always banned now<br />However these gadgets are sliding by<br />Hook it to a box of insulation or duct work and jam<br />Out<br />Ive found the sticky pads where out pretty quick but a pc of tape over the back works dandy<br />I would suggest rechargeable aaa batteries though<br />All in all a bad ass little gadget that does what it's sposed to
