Bose QuietComfort Ultra Earbuds (2nd Gen) review

The second-generation QuietComfort Ultra Earbuds are Bose's most advanced in-ear model and cost $299 on Bose's US store. Bose describes the noise cancelling as its best in-ear performance, with an improved ActiveSense adaptive mode that lets you stay aware without the full seal dropping away. For calls, the 2nd Gen adds SpeechClarity, an AI-based system that filters out surroundings and wind to focus on your voice. CustomTune calibrates sound and noise cancelling to the shape of your ear, and Immersive Audio spatializes stereo music. The box includes three eartip sizes and three stability bands, which helps if other earbuds fall out, and the case now charges wirelessly. The weak spot is endurance: Bose lists up to 6 hours per charge and 4 hours of maximum talk time, less than Sony, Apple and Google. If your commute plus a work call runs longer than that, Pixel Buds Pro 2 or Soundcore Liberty 5 last longer.
