They combine hybrid active and passive noise cancellation, customizable sound, Bluetooth multipoint connectivity, up to 24 hours of battery life, a lightweight foldable design, and plush around-ear comfort. The hybrid noise-cancelling system combines electronic active noise reduction with passive isolation from the cushioned earcups. Microphones positioned around the headphones monitor surrounding sound and help reduce environmental distractions, while the physical earcup seal provides additional passive isolation. This combination is designed to reduce steady background noise such as transportation rumble, office activity, and other everyday distractions. Quiet Mode provides strong noise reduction for focused listening, while Aware Mode allows surrounding environmental sound to pass through when greater situational awareness is needed. Custom listening modes allow users to personalize noise-control settings, while Wind Block helps reduce wind interference during outdoor use. The headphones deliver a balanced Bose sound profile with strong bass, clear midrange reproduction, and smooth high-frequency detail. Adjustable EQ through the Bose app allows listeners to tailor bass, midrange, and treble to suit different types of music, spoken content, movies, and personal listening preferences. Bluetooth 5.1 with multipoint connectivity allows the headphones to remain connected to two compatible devices simultaneously. This makes it easier to move between devices such as a smartphone and laptop without repeatedly disconnecting and pairing. Bose SimpleSync can also connect the headphones with compatible Bose soundbars and speakers for personalized listening. Plush earcup cushions and a padded adjustable headband are designed for extended listening comfort. The headphones fold for compact storage and transportation inside the included carrying case, while physical earcup controls provide direct access to playback, volume, calls, and noise-control functions. Battery life reaches up to approximately 24 hours of wireless playback, while a 15-minute quick charge can provide approximately 2.5 hours of additional listening. USB-C provides convenient charging, and the included analog audio cable supports wired listening when Bluetooth is unavailable or not preferred. The headphones weigh approximately 238 grams / 8.4 ounces, helping keep them comfortable during longer listening sessions. | Bundle | | Bose | QuietComfort Wireless Over-Ear Bluetooth Headphones Power | Black | Best Buy
