If sound quality and active noise cancelling are key for you, and you're after a premium experience with better build and comfort, the Focal Bathys would be the choice despite the higher price. They are also versatile for most uses, including music, calls, and travel, and come with features like wireless connectivity and app equalization. However, if budget is a concern and you're looking for decent sound quality at a much lower price, the KZ ZSN Pro earbuds could work well, especially for casual listening and portability; they also have a detachable cable, which is a plus for durability.

"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."

"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."
