If you prioritize noise cancellation and wireless convenience for daily commutes or flights, the Bose QuietComfort Earbuds II with excellent noise isolation and very good comfort are worth the higher cost. They also have a better build quality and extra features like an app equalizer and ear/head detection. However, if you're on a budget and want earbuds primarily for wired listening with good overall sound, the KZ ZSN Pro X offers a detachable cable and a dynamic driver setup, but lacks active noise cancellation and wireless capability. The KZ earbuds are also less suitable for exercise as they're not sweatproof certified. Give Feedback

What HiFi?
What HiFi? | September 2023
"Bose’s flagship wireless earbuds were never going to be cheap, but the question was whether they’d be competitive in an area of the market where rivals have never been more capable. The fact that the company has not only managed to implement a successful redesign, but also push the envelope for noise-cancelling and sound quality in such a highly competitive category simultaneously is truly impressive."

"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."
