Whether you’re at a Bangkok hostel or backpacking in Goa, you can rock out to your favorite tunes with these portable Rock ’n’ Roll Speakers, a set of customizable, low-fi travel speakers that allow you to take your music everywhere.

The speakers are driven by a simple power amplifier circuit and a tilt switch. With a simple flip, these portable speakers are switched on and off: when both speakers are visible the speakers are on, and when only one speaker is visible they’re off. Powered by a 9V battery, the Rock ’n’ Roll Speakers are the perfect compact travel companions for adventurous jet-setters.
