The Bang & Olufsen A8 Headphones are incredibly light and offer amazing sound quality. Dynamic full tone loudspeakers are mounted on a telescopic bar made with the open loudspeaker principle which enables you to hear some environmental sounds. This means you won't be completely cut off from the outside world when enjoying the pure sounds. Designed using carefully selected materials, the A8 Earphones are made from brushed aluminium and a soft-touch rubber coating. These durable materials offer comfort and weigh only eight grams on the ear. Standard in-ear earphones can start to feel uncomfortable or have trouble staying in you're ear when you move around. Unlike other earphones, the A8 can be adjusted to fit the contours and curves of your ear. This ensures the headphones stay comfortable and inside the ear when you're exercising or relaxing.
