Long ago, before someone at Sony invented the Walkman, macho dudes would walk the streets of New York with a boom box, blasting their music to everyone within earshot, whether they liked it or not. We've had over 30 years of relative peace since then, but now some Dutch company wants to reintroduce a line of obnoxious neighborhood noisemakers.
The Solid Gray backpack is normally just a hip geometric backpack that makes you look a bit like a cyborg on the go. This speaker-equipped version is essentially the same underneath, but with an array of speakers built into the shell. No real details were offered about the audio system itself, but it does look like there's plenty of "oomph" there to make it truly obnoxious.
The good news for all of us peace-loving folks is that the speaker backpack is just a one-off prototype with no current plans for production. Solid Grey's standard backpacks run around $170 each, so if you're handy with a jigsaw I'm sure you could come up with your own replica. Just promise not to crank it up near me.
