If you prioritize sound quality and are willing to invest in a high-end product, the Focal Bathys would be the superior option with exceptional overall sound quality, and they are especially good for enjoying music and TV. They also feature active noise cancelling for better immersion and reduced distractions, but come with a higher price. On the other hand, if you're looking for a more budget-friendly option with good build quality and a microphone, and plan to use them primarily for calls and meetings or while exercising, the KZ ZSN Pro (with Mic) may suit your needs. However, the KZ ZSN Pro lacks wireless functionality and noise cancellation. Give Feedback

"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."
