Bose QuietComfort Ultra Wireless Over-ear Headphones, Blue

The Bose QuietComfort Ultra are over-ear wireless headphones designed for audio playback and voice calls. They connect to devices primarily through Bluetooth 5.3, which supports multi-point pairing for simultaneous connections to two sources. The acoustic design is closed-back and incorporates an adaptive active noise cancelling system to reduce ambient sound. For audio personalization, the headphones utilize CustomTune technology to adjust the sound profile to the user's ears. A detachable 2.5 mm to 3.5 mm audio cable is included for optional wired connectivity.

The headphones provide up to 24 hours of continuous playback on a full charge, with a battery recharge time of three hours via the USB-C port. A 15-minute fast charge delivers additional listening time. User controls are managed through a combination of physical buttons and a touch-sensitive surface on the earcups, allowing for volume adjustment, track navigation, and call management. The integrated microphone array is designed for clear voice pickup during calls. The build consists of premium plastics and protein leather ear cushions, with a total weight of 250 grams.
