Unmatched Silence with Bose QuietComfort Ultra Earbuds (2nd Gen)
The Bose QuietComfort Ultra Earbuds (2nd Gen) represent the pinnacle of noise-cancelling technology. Specifically, these earbuds utilize Bose’s proprietary CustomTune technology, which automatically calibrates the sound and noise cancellation to the unique shape of your ears every time you put them in.
Consequently, you get a personalized audio profile that blocks out distractions more effectively than ever before. Whether you are on a noisy flight or working in a busy cafe, the “Quiet Mode” provides total immersion, while “Aware Mode” keeps you connected to your surroundings with unmatched clarity.
Spatialized Sound and Immersive Audio
This second-generation flagship introduces a new era of listening with Bose Immersive Audio. First, it spatializes what you’re hearing, taking it out of your head and placing it in front of you for a more natural, “cinema-like” soundstage.
Second, the new Cinema Mode optimizes audio for video content, balancing background effects with crystal-clear dialogue. Moreover, with support for aptX Adaptive and Snapdragon Sound, these earbuds deliver high-resolution, lossless audio quality. Therefore, every track feels fuller, more realistic, and deeply engaging, regardless of the genre or device.
Refined Connectivity and All-Day Power
The Bose QuietComfort Ultra Earbuds (2nd Gen) are designed for seamless daily use. For instance, Multipoint Connectivity allows you to stay paired with two devices simultaneously, such as your laptop and smartphone, switching between them effortlessly.
Furthermore, the upgraded AI-powered noise suppression system ensures your voice sounds clear and natural during calls, even in windy or loud environments. Because the charging case now supports Wireless Charging right out of the box, powering up is easier than ever. Additionally, the IPX4 rating ensures durability against sweat and light rain, making them the perfect partner for workouts and travel.
