Beoplay H4 2nd Gen Wireless Over-Ear Headphones (Limestone)
Product Description
Leveraging nearly 100 years of audio engineering, the Bang & Olufsen Beoplay H4 2nd Gen Wireless Over-Ear Headphones work to deliver crisp, clear, and accurate sound from their 40mm dynamic drivers. The over-ear design provides significant passive noise canceling and isolation that allows for a more enjoyable experience. They are crafted for long term durability, as they are made from leather, aluminum, stainless steel, and braided fabric. In the short term, they have enough power to last up to 19 hours of playback on a single charge.
