Beosound Level in the colours Natural and Gold Tone is the world’s first Cradle to Cradle Certified speaker (bronze level). Cradle to Cradle is the global standard for products that are safe, circular and responsibly made. That means you can easily upgrade it as technology evolves, if the battery runs out or if you want to change the colors. Next year or a decade from now. That’s part of future-proofing our products.
