Nearly two years after launching the original QuietComfort Ultra Earbuds, Bose is preparing to release an upgraded second-generation model that addresses key user complaints while maintaining the same USD 299 price point. The announcement comes as the audio company continues to refine its flagship earbud lineup with targeted improvements rather than a complete overhaul.Key Specifications ComparisonFeature1st Gen2nd GenPriceUSD 299USD 299Battery Life6 hours (4 with Immersive Audio)6 hours (4 with Immersive Audio)Wireless ChargingNoYesBluetooth5.3 with multipoint5.3 with multipointMicrophones8 total (4 per earbud)8 total (4 per earbud)Color OptionsLimitedBlack, White Smoke, Deep PlumEnhanced AI-Powered Noise CancellationThe most significant upgrade centers around Bose's improved AI algorithms for noise cancellation. The second-generation earbuds feature enhanced ActiveSense technology that promises smoother transitions between transparency mode and active noise cancellation. This refinement specifically targets the jarring experience users sometimes encountered when the earbuds rapidly switched between different noise-canceling modes in response to sudden environmental changes.Improved Voice Call QualityAddressing one of the major criticisms of the original model, Bose has implemented new AI-powered noise suppression technology to enhance voice pickup during phone calls. The first-generation earbuds struggled significantly in noisy environments, often failing to clearly capture the user's voice. The upgraded system combines dynamic mixing and adaptive filters with the earbuds' eight built-in microphones to deliver clearer call quality even in challenging acoustic conditions.Wireless Charging and Design RefinementsThe second-generation model introduces wireless charging capability, a feature notably absent from its predecessor. While battery life remains unchanged at six hours with standard audio or four hours with Immersive Audio enabled, the charging case continues to provide three additional charges. A quick 20-minute charge reportedly delivers up to two hours of playback time.Design improvements include an eartip guard system designed to prevent earwax buildup and simplify cleaning maintenance. Bose has also added customization options, allowing users to disable capacitive touch controls entirely—a welcome addition for those who experienced accidental activations.Major Improvements in 2nd GenerationEnhanced AI algorithm for smoother ActiveSense transitionsAI-powered noise suppression for better call qualityWireless charging supportEartip guard to prevent earwax buildupOption to disable capacitive touch controlsDynamic mixing and adaptive filters for voice pickupMaintained Features and AvailabilityCore specifications remain consistent between generations, including Bluetooth 5.3 connectivity with multipoint support, aptX Adaptive codec compatibility, and Bose's Immersive Audio spatial sound technology. The earbuds will launch this summer in three color options: Black, White Smoke, and a limited edition Deep Plum variant.The USD 299 pricing strategy positions these earbuds competitively within the premium noise-canceling segment while delivering incremental but meaningful improvements to the user experience.
