The Bose QuietComfort Earbuds offer superior overall sound quality and active noise cancelling, making them ideal for music listening and air travel. They also have higher comfort and build quality scores, making them a more premium choice. However, they come at a premium price compared to the KZ ZSN Pro, which has a detachable cable and potentially longer durability due to replaceable wires. The KZ ZSN Pro also includes a microphone and performs well for calls. If cost is a major concern and you need a wired connection with a mic, consider the KZ ZSN Pro. For a top-tier wireless experience with better sound isolation and comfort, and if budget permits, opt for the Bose. Give Feedback

Christian Thomas | October 2023
"Bose put the time in to fix the major issues with the previous earbuds, and the Bose QuietComfort Ultra Earbuds are very befitting of its price point. While you might be tempted to save a few bucks and go with the Bose QuietComfort Earbuds II on sale, fight the urge. There are enough upgrades here to justify the newer model."

"Undoubtedly the focus and the star of the show, the ZSN Pro’s bass is big, bold and bangin’. The amount of gusto in the low end should satisfy anyone who likes a large lick of bass and even certified bassheads will probably get a kick out of this."
