The Focal Bathys are a premium choice offering noise cancellation, Bluetooth connectivity with high-quality codecs, and a built-in microphone for calls, which are significant advantages if you need to block out distractions, prefer wireless freedom, or take frequent calls. However, they're considerably pricier than the Sennheiser CX300S, which offer good sound quality for their price point but lack these features. If cost is a concern and you're content with basic wired earbuds without extra frills, the Sennheiser CX300S may be more suitable. Otherwise, for a more versatile and high-end listening experience, the Focal Bathys are the better option, albeit at a higher price. 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."

Carroll Moore | April 2019
"Sennheiser offers impressive bang for your buck when it comes to the CX 300S. Built like a tank and sounding surprisingly good for such a budget-minded earphone, the CX 300S out-classes many of its would-be competitors. Functional but beautiful, it’s the perfect in-ear listening solution for anyone who wants to hear everything and look good doing it."
