                  Overview

                  Enhanced Noise Cancellation

                  Delivering the most advanced noise cancellation yet, these BOSE QuietComfort Ultra Bluetooth Wireless Headphones set a new standard in immersive listening. They are powered by a proprietary combination of active and passive noise reduction. So, whether you’re travelling on a plane, commuting in a noisy city, or working in a busy café, you can focus entirely on your music or calls without distraction.


                  BOSE Immersive Audio

                  Engineered with Immersive Audio technology, these headphones place sound in front of you, creating a spatial listening experience that feels natural and open. Thus, it’s like enjoying music live in the room rather than through headphones, adding depth and realism to every track.


                  Immersion Settings

                  Featuring both Still and Motion modes, these headphones adapt audio to your environment. In Still mode, sound remains anchored in the room even if you move your head. In Motion mode, the sound follows your movements, offering flexibility for both relaxation and on-the-go listening.


                  Extended 24-Hour Battery Life

                  Designed with a long-lasting battery, these Bluetooth headphones offer up to 24 hours of playtime in Quiet or Aware Mode, and 18 hours with Immersive Audio. So, whether you’re travelling abroad or working long days, you can count on uninterrupted listening.


                  Seamless Bluetooth Multipoint Connectivity

                  Equipped with Bluetooth multipoint technology, these wireless headphones can connect to your laptop and phone simultaneously. Therefore, you can stream music from your laptop while staying ready to take calls from your smartphone without switching connections manually.


                  Clear Calls

                  Fitted with a revolutionary microphone system, these Bluetooth headphones ensure your voice sounds crisp and clear even in noisy environments. This makes business calls, virtual meetings, and catch-ups with friends more natural and effortless.


                  Reliable and Portable

                  Built with a lightweight and foldable design, these BOSE headphones are easy to carry in a bag or backpack. Consequently, they fit seamlessly into your daily routine, whether you’re commuting, travelling, or simply moving between rooms.


                  Luxe Comfort and Design

                  Crafted with premium materials and a balanced headband, these Bluetooth headphones ensure lasting comfort during extended listening sessions. The earcups gently hug your ears while the elevated finishes create a sophisticated look, making them as stylish as they are comfortable for everyday use.
