They combine Bose active noise cancellation, CustomTune™ ear calibration, ActiveSense™ adaptive processing, TrueSpatial™ Immersive Audio, Snapdragon Sound support, Bluetooth multipoint connectivity, IPX4 water and sweat resistance, and up to 30 hours of total listening time with the charging case. CustomTune™ technology automatically calibrates the earbuds to the acoustic characteristics of the listener’s ears. When the earbuds are inserted, the system analyzes the acoustic response and adjusts both sound reproduction and noise-cancellation performance to help optimize the listening experience for the individual fit and ear shape. ActiveSense™ technology enhances Aware Mode by helping reduce sudden spikes in environmental sound while still allowing surrounding audio to pass through. This makes transparency listening more comfortable in changing environments where abrupt sounds such as traffic, machinery, or transportation noise may otherwise become distracting. Multiple listening modes provide flexibility for different environments. Quiet Mode delivers strong active noise cancellation for focused listening. Aware Mode allows environmental sound through while using ActiveSense processing, and Immersion Mode combines active noise cancellation with Bose Immersive Audio for a more spacious presentation. Bose TrueSpatial™ Immersive Audio creates a broader listening experience by positioning the perceived soundstage outside the listener’s head. Still and Motion modes provide different spatial behaviors depending on whether the listener is stationary or moving. Snapdragon Sound support provides access to aptX Adaptive and aptX Lossless on compatible devices, while SBC and AAC codecs maintain broader compatibility across smartphones, tablets, computers, and other Bluetooth sources. Bluetooth multipoint allows the earbuds to remain connected to two compatible devices simultaneously. Battery life reaches up to approximately 6 hours per earbud charge in Quiet or Aware Mode and up to approximately 4 hours with Immersive Audio enabled. The charging case provides additional recharges for up to approximately 30 hours of total listening time. The case supports both USB-C and Qi wireless charging. An IPX4 water-resistance rating helps protect the earbuds against sweat, splashes, and light rain. Three sizes of ear tips and three sizes of stability bands provide multiple fit combinations to help create a secure and comfortable seal for different ear shapes. | Bundle | | Bose | QuietComfort Ultra Earbuds 2nd Gen Wireless Headphones Power | Black | Best Buy
