Even your most basic outdoor store will sell you a collapsible silicone drinking cup that helps keep your backpack as light as possible when hiking. And it turns out that same strategy can apply to portable speakers too, like the making them even easier to stash in a bag when not in use.
Available in a bright assortment of colours for just under $US8, the SSSSSpeaker (those extra S's aren't typos) runs for eight hours when its USB rechargeable battery is full, and it connects to an audio source using a standard 3.5mm headphone jack. So there's no Bluetooth to drain the speaker's tiny battery, or your phone's.
It's also in the running for a Red Dot Design Award, which most often means a product is just a pie-in-the-sky concept. But the SSSSSpeaker is real, and ready to provide a soundtrack to your next camping adventure. [Aiia]
