It comes as no surprise that a device that transmits audio, turning most anything to a speaker, would draw curiosity to us, especially for me who has to work with a different audio set-up than one what’s usually found in one’s car. Seeing as mine’s a bit of an old-clunker with no radio, improvisation is my friend, and to Rock-It 3.0’s credit, it works well enough..
Let me be clear here, this device isn’t anything you’d expect to be hauling around in your brand new SUV or luxury sedan. It’s a neat little gadget you can use to attach to a surface, and turn any object into a speaker. As long as that object is hollow, and has a surface to stick to, you could turn a soda can, empty Tupperware, cardboard box, even a lampshade into a homemade speaker system. This little device is pretty nifty for when you have a large, empty object to generate acoustic sounds without needing to spend hundreds of dollars on a brand-name speaker system.
Is the audio any good, you ask? Well, to some degree, but this is a very material-specific device. Where plastic can be counted on to give you some decent sound, something like Styrofoam or cardboard is a hard sell. I’ve gotten the best audio out of a large plastic chest of drawers, as the empty space within allows for a good containment for sound waves to vibrate within, allowing for a nice acoustic space to generate sound. Size matters here, too, and like I said, the materials that make up your speakers-of-choice can effect whether or not it sounds like a full-blown audio system, or something being produced out of a 90’s car radio.
You’ll probably want to invest in Velcro strips. The tiny, circular sticky pads are a just above being useless, and unless you’re marrying your device to a particular object in the long-term, you’ll probably find that the pads tend to lose their stick rather quickly. Of course, it’s up to you to decide which adhesive options you use in attaching the diaphragm nub to. Velcro might hinder audio quality and volume, so keep note of that if you go that route.
The system itself is very compact and portable, leading to reason why it’s given such weak adhesive pads for a connector. This 4×1 ½ inch device is EXTREMELY portable, and features rechargeable batteries, a 6” long audio cable, a bit of 1-foot of cable between the audio nub and the speaker itself which can be wound up by turning the swivel end of the device, an audio-in and charge/line-in micro USB 2.0 port. The package that the device comes in sports a cable with 3 heads, a basic USB connector and Micro USB connector and audio jack, as well as 2 extra stick pads, and a basic guide on usage. At the moment, I only own one of these devices, so I cannot say whether or not they can be interconnected to create a multi-speaker set-up, but if your friends and you own one of these, feel free to experiment at your leisure.
All in all, it’s not bad, though it feels a bit cheap and not exactly made of the sturdiest of plastics. At a loss of about $20 bucks, it’s not a bad alternative to buying an expensive audio system, and the technology behind pretty cool, if not intriguingly inventive. Like I said, keep note of the surfaces you use it, and find the one best suited for the audio you want to produce.
