On Running and the Danish consumer electronics company Bang & Olufsen have jointly released a running kit, combining the Swiss sporting goods company’s Cloudboom shoe with a limited edition of Bang & Olufsen’s first wireless earphones, the Beoplay E8 Sport On Edition. The Beoplay earphones are made of rubber, textured silicone and corrosion-resistant anodised aluminum, with a ridged grip to permit adjustments by sweaty fingers. A finger tap or swipe will switch music tracks, take calls or activate Transparency Mode. The Cloudboom has CloudTec cushioning, a carbon-fiber infused Speedboard, a single layer of lightweight, breathable mesh, a rocker-shaped sole with a “grip-rubber compound” and an “advanced traction pattern.”  The kit is on sale at on-running.com and at selected stores.
