The pinnacle of the BeoPlay collection from Bang & Olufsen comes in the form of their wireless H9 headphone with active noise cancellation. Unlike many of its counterparts in the market, the H9 is almost entirely devoid of plastic components, instead opting for natural materials. The over-ear design sits comfortably due to the softness of the lambskin and adaptive memory foam so you can easily use all 14 hours of noise-canceling battery life for tunes or to take your calls on the go without your ears protesting. The highly-advanced polished and anodized aluminum plate on the ear cup is sensitive to the touch, allowing you to adjust volume and active noise cancelling even with gloves on. A major plus for long-haul jet-setters is the ability to remove and replace the Lithium-Ion battery in seconds, allowing for virtually unlimited cord-free play time.
