If you prioritize exceptional sound quality for music and TV, and can accommodate a high-end price, the Focal Bathys are suitable, with the caveat that they are less portable and their over-ear form requires battery power even when wired. Conversely, the Sennheiser Momentum True Wireless 4, while also delivering very good sound quality, are more affordable, offer great battery life with wireless charging, advanced Bluetooth features, and are optimized for exercise due to their sweatproof design. However, their in-ear form and smaller size may be less comfortable for extended periods compared to over-ear designs. 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."

What HiFi

Andy Madden | January 2024
"It’s fair to say our brief time with the Sennheiser Momentum True Wireless 4 was a generally positive one. Comfort levels seem similar to what we have experienced before and the general flavour of sound was to our liking although we need to get a pair in to test and put up against the big rivals at the money from Bose and Sony. It could be an interesting contest."
