The Focal Bathys headphones provide a superior overall sound quality and a better experience for gaming, TV, and video with scores indicating high performance in these areas. However, the Sennheiser Momentum 4 offers much better microphone quality, making them a better choice for calls and meetings, and they have a significantly longer battery life. Both have active noise cancelling and are not rated for sweat or dust resistance, suggesting neither is ideal for rigorous exercise. The Bathys are heavier, possibly affecting comfort over long periods, and don't support low latency mode. If budget allows and immersive audio is a priority, the Bathys excel, but for daily versatility and extended wear, the Momentum 4 may be the more practical, cost-effective choice. 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."

"If you're looking for a slightly more affordable set of ANC headphones in comparison to the Bose or Sony offerings: the Sennheiser MOMENTUM 4 Wireless is not a bad way to go. While its ANC is technically behind the other top-tier headphones, its sound quality is ahead of the pack—as is its battery life. Not bad for $350 USD."
