QuietComfort Ultra Earbuds (2nd Gen)

The Bose QuietComfort Ultra Earbuds (2nd Gen) are flagship true wireless earbuds that combine world-class noise cancellation with a refined, feature-rich design. Released as a mid-2025 refresh, they retain the iconic stem-style look while introducing long-awaited hardware upgrades like integrated wireless charging for the case as a standard feature and a more advanced AI-powered microphone system for superior call clarity in noisy environments. They are powered by the Qualcomm QCC5181 chipset, enabling Bose Immersive Audio for a wide spatial soundstage and CustomTune technology, which calibrates the sound profile to the unique shape of your ear canal every time you put them on. With a battery life of 6 hours (up to 24 hours with the case), an IPX4 water-resistance rating, and the addition of aptX Lossless support for CD-quality streaming on Android, these earbuds are designed to provide a premium, personalized listening experience for travelers and commuters alike.
