Enjoy high-quality audio without distractions thanks to the Shure AONIC 50, a pair of wireless, over-ear headphones styled in dark brown. These headphones are designed to deliver a 20-hour battery life, noise cancellation, and a pleasurable sound. They do this over Bluetooth 5.0, giving you a range of up to 30' from your computer, phone, or tablet. The headphones make use of 50mm dynamic drivers that utilize neodymium magnets and produce a wide frequency response of 20 Hz to 22 kHz. A 3.5mm cable is included for battery-saving wired operation, as is a USB Type-C cable for charging and for listening to hi-res audio. Active noise cancellation attenuates the background noise, so you can curate an immersive listening experience as you go about your day. With the flip of a switch, you can put the headphones into Environmental Mode, which allows you to hear the outside world, so you can pay attention to your surroundings. You can also play/pause your music, adjust the volume, and answer phone calls with the push of a button. The headphones are comfortable and durable. They'll also fold flat for convenient storage. In addition to the 3.5mm audio cable and the USB Type-C cable, a protective carrying case is included for transport. - Shure Aonic 50 Wireless Noise-Canceling Headphones Brown
