Recycled cardboard


Less Garbage

The Berlin Boombox is made of recycled cardboard* and can itself be recycled. It only contains a small portion of plastic and electronic waste. With the packaging we also avoid unnecessary shrink-wrapping, plastic materials and the like.

*Brown colorway: 100% recycled cardboard. Other colors: partially recycled cardboard.


The lightweight and flat packaging means less energy is used for shipping. Our class D amplifier is very energy-efficent, too: 3 AA batteries will give you 200 hours of music.

Supporting local Businesses

All design, screen-printing and production of the cardboard case is done locally in Berlin. Packaging and logistics are done by a sheltered workshop..

Modular Concept

The modular kit concept of the Berlin Boombox lets us send only the necessary replacement parts to our customers who can replave them themselves. This saves everyone money, nerves and energy.

We are sure that the Berlin Boombox is the most eco-friendly powered stereo speaker on the market.

Our Story

Music & Design

Axel Pfaender is an illustrator, designer and DJ. With the Berlin Boombox he decided to combine his two passions – music and design. In 2012 he started a Kickstarter project to get the necessary funds to bring the Berlin Boombox to the market.


The Kickstarter project was very successful, reaching $20,000 after only 30 days. But even more important than the money: the tons of positive feedback, suggestions from backers, retailer request and love from design blogs, gadget blogs, magazines, and radio stations. It was a real highlight when Kickstarter founder Perry Chen visited us in Berlin and checked our first prototype.

Bringing Crowd-Funding to Germany

The success of the Berlin Boombox on Kickstarter came at a time when crowd-funding was a new thing in Germany. Axel Pfaender quickly became a sought-after speaker on the topic and advisor for others who where aspiring to be succesful with crowd-funding their projects.

What's next?

In September 2012 the first black and white model of the Berlin Boombox was launched. Since then, we have been continuously developing new colorways and designs. The Berlin Boombox is available at retailers worldwide - find a store near you with our Store Finder. We collaborate with international artists to create special editions.
