Bose QuietComfort Ultra Wireless Over-ear Headphones, White

The Bose QuietComfort Ultra are over-ear headphones that feature a closed-back acoustic system with dynamic drivers. The primary function is noise cancellation, which utilizes both active and passive methods to reduce ambient sound. For voice communication, an adaptive microphone system is integrated, which also incorporates noise-canceling technology to isolate the user's voice during calls. Digital Signal Processing (DSP) is used to manage audio output and microphone input for consistent performance.

These headphones provide dual connectivity options: wireless via Bluetooth 5.3 and a wired connection using the included 3.5 mm to 2.5 mm detachable cable. The internal lithium-ion battery supports up to 24 hours of playback and can be fully recharged in two hours via its USB-C port. A 15-minute fast charge provides additional listening time. The physical build consists of aluminum, plastic, and leather components, with a total weight of 254 grams. Controls for volume, media playback, and call management are located on the earcups.
