B&O PLAY by Bang & Olufsen Beoplay H6 (Black) Connectivity Technology: Wired Carefully selected high quality materials like leather and aluminum make Beoplay H6 comfortable to wear and bring a sense of everyday luxury. Also, every day wear and tear merely adds patina, and makes BeoPlay H6 age beautifully. The head band needs to be durable and age with grace. Therefore, we have chosen cow leather, that gains patina and personality when worn. B&O PLAY products come with a 2-year limited warranty only when purchased from an authorized dealer including Amazon.com (indicated by ships from and sold by Amazon.com).Dimensions - 7.8 X 7.6 X 1.6 in Includes a 40 mm custom designed driver with a neodymium magnet in a closed headphone design. BeoPlay H6 has a bass port which optimizes the bass performance and the drivers are slightly angled to get the best distance and sound direction into the ears.
