If comfort and overall sound quality are your top priorities, along with features such as active noise cancelling and wireless connectivity, the Focal Bathys would be an excellent choice, though it comes at a higher cost. However, these require battery power even when wired and are not as portable. The KZ ZSN Pro X, on the other hand, is more budget-friendly with good sound quality and is portable, but lacks noise cancellation, wireless functionality, and has lower build quality. The KZ is also suited for wired use without power concerns since it does not require charging. For traveling or commuting, Bathys' noise cancellation could be a significant advantage, while the KZ might be more convenient for casual use or physical activities due to their lighter weight and fit accessories.

"As much as I hesitate to recommend a headphone that sells for $800 USD, if you’re looking for the best sound quality you can find in the ANC space: it’s the Focal Bathys."

Jasper Lastoria | April 2023
"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."
