Listen to your music on the go and without distractions with the 3rd generation Beoplay H9 Noise-Cancelling Wireless Over-Ear Headphones from Bang & Olufsen. B&O's sound engineers have worked to tune the H9 headphones to provide deep and rich sound via the electro-dynamic 40mm drivers and integrated bass ports. As you listen, active noise cancellation technology works to filter out the ambient sounds around you.
Even with active noise cancellation engaged, the Beoplay H9 headphones can deliver up to 25 hours of playback. Music is streamed from your Bluetooth-compatible device, such as a smartphone. If you pair these wireless headphones with a phone, you can use the built-in microphone for hands-free calling. Built-in touch controls let you keep your phone in your pocket or purse. You can answer calls, adjust playback, and even engage with your digital voice assistant.
