If you prioritize a wireless experience and active noise cancelling for frequent travel or noisy environments, the Bose Quiet Comfort Earbuds are a better fit, with excellent noise isolation and very good comfort. However, if you are on a budget and prefer wired earbuds with the capability for balanced audio through additional cables, the KZ ZSN Pro X would be more suitable. The Bose offers superior call quality, better suitability for exercise with sweatproof certification, and an overall better sound quality, but they are considerably pricier. The KZ ZSN Pro X, while less advanced in features, offer very good build quality and sound at a much more affordable price point. Give Feedback

Lily Katz | March 2023
"The Bose QuietComfort Earbuds is a great do-it-all option for anyone, so long as you can afford it. This is a great alternative to the Apple AirPods Pro and Sony WF-1000XM4. You can choose the degree of noise canceling, and enjoy premium features like automatic ear-detection. These earbuds merit an IPX4 rating, making them a fine workout companion."

"The KZ ZSN PRO X offers superb sound for very little money, like under $30 USD. It has some rough edges with a plastic seam on the cable that can rub on your ear, and the bud is a bit large. The tech isn't cutting edge, but new doesn't always equal better. You should try it."
