Two years ago, Review Geek scored the Sennheiser Momentum 3 Wireless headphones a 9/10 after a detailed review. But one small detail kept us from giving the Momentum 3 Wireless a perfect score---the battery life kinda stank. Did Sennheiser take that complaint to heart? Uh, yeah.

UPDATE: 8/22/22 10:12 am Eastern

The Sennheiser Momentum 4 headphones are available today for $350.

Sennheiser just gave us a first look at the Momentum 4 Wireless, a new iteration of its flagship Bluetooth headphones. And the battery life is rated for 60 hours. That's three times the battery life of Apple's AirPods Max.

Aside from the outrageous battery life, Sennheiser says that the Momentum 4 Wireless headphones offer "best-in-class" sound, ANC, and comfort. There's also a new design, which looks similar to the Momentum earbuds' fabric charging case, and Sennheiser will continue to offer in-app controls and customizations for the headphones.

We also know that the Momentum 4 Wireless use 42mm drivers (just like their predecessor). But these drivers are angled to provide a more natural soundstage. Additionally, new microphone technology increases Momentum 4 Wireless call quality and improves voice assistant performance.

Sennheiser's Momentum 4 headphones are available August 22nd for $350. You can purchase the headphones at the Sennheiser website, Amazon, Best Buy, or other major retailers.
