What Buyers Say
Bose QuietComfort Ultra 2nd Gen
The Bose QuietComfort Ultra Earbuds (2nd Gen) receive praise for their excellent sound quality and noise cancellation, with many users calling them the best earbuds they've owned. However, a significant number of reviewers report issues with fit, especially for larger ears, and the touch controls are often described as overly sensitive, leading to accidental commands. Battery life and charging inconsistencies, along with occasional connectivity problems, also detract from the overall experience. While many are satisfied, the mixed feedback on comfort and functionality suggests these earbuds may not suit everyone.

- Great noise cancellation
- Comfortable for long wear
- Good battery life
