The Bose QuietComfort Earbuds II are stemless, closed-back earbuds well-suited for a variety of uses. If you prioritize comfort and noise isolation, particularly during air travel or while exercising, these earbuds excel in those areas, providing a secure fit with stability bands and offering active noise cancelling. They feature a very good overall sound quality that would enhance music listening, although they're not the top pick for gaming or watching TV due to fair performance in those aspects. For calls and meetings, the quality is only fair, which could impact clarity during conversations. The build quality is robust, and the built-in controls are rated the best for ease of use. They leverage dynamic drivers and support the AAC codec, which improves performance with Apple devices, but do not have a lossless codec for audiophile-level sound quality. They are sweatproof, making them practical for exercise, but there is no mention of dustproof certification. The battery life stands at 7 hours, with the case providing an additional 20 hours; however, they do not support wireless charging and take 2 hours to charge fully. The companion app offers equalizer settings, controls customization, and audio controls to tailor your listening experience. Keep in mind that these earbuds come with a premium price tag, so if budget is a concern, this should be considered. Give Feedback
