To create the unique surface appearance, extruded aluminum pieces “are milled, polished, and anodized—an electrochemical treatment that forms a durable oxide on the surface of the material.” Following the treatment, Bang & Olufsen’s surface specialists spend time fine-tuning the gradient effect. This production process is extremely labor-intensive, so only 1,200 pieces of the Beosound 1 New York Edition were made. As with all Beosound 1 editions, the portable speaker features 360-degree dispersion of sound thanks to its tower-like shape, as well as a built-in Google Assistant and a built-in rechargeable battery that can last for up to 12 hours of playtime.
