Sennheiser promises 60 hours of listening with its new Momentum headphones

Sennheiser hasn't refreshed its over-hear Momentum noise-canceling headphones since 2019, but that changes today. The company has announced the Momentum 4, a new take on its flagship headphones that includes an exterior redesign, new features and a whopping 60 hours of battery life. What's more, Sennheiser is offering this host of updates for $50 less than the Momentum 3 at its debut.

First, the design Sennheiser had carried through much of the Momentum line since its introduction is gone. The mix of metal and leather with visible cables has been traded for a more simplified, more plastic affair. The new look is decidedly less premium than previous Momentum models. However, what the Momentum 4 may lack in aesthetics is offset by increased comfort. The company notes the new hinge easily adjusts and doesn't exert too much pressure on your head. Earcups also rotate flat now, which makes storage a bit easier. Another big change is the on-board controls: most of the physical buttons have been replaced with a touch panel on the right side.

Inside, Sennheiser says it opted for an "audiophile-inspired acoustic system" that relies on 42mm transducers for the sound. The company explains the setup creates "brilliant dynamics, clarity and musicality," plus you can use an EQ, presets and a new Sound Personalization feature to further adjust the tuning. Sound Personalization takes into account your personal preferences and adjusts "the listening experience" accordingly.

Of course, these are flagship headphones so active noise cancellation (ANC) is on board. The company says its updated adaptive ANC works to maintain sound quality even in the noisiest of surroundings. Transparency Mode is available as well and there's a slider control between it and ANC in Sennheiser's app. In other words, you're not just left with one or the other, so you can mix in a dash of environmental noise if needed. This model can automatically change sound settings based on your location too, a feature Sennheiser first debuted in March.

Sennheiser also offers a feature called Sidetone, which allows you to adjust how much of your voice comes through during calls. It's a tool that helps you feel less shouty and it works on top of automatic wind noise suppression for the Momentum 4's beamforming microphones during voice and video chats.

Sennheiser says you can expect up to 60 hours of battery life on a charge, and that's with ANC turned on. A quick-charge feature gives you six hours of use in 10 minutes. To help you conserve battery, the Momentum 4 is equipped with both automatic pausing and automatic on/off. The company says the headphones will power off when you leave them unattended and turn back on when you pick them up.

The Momentum 4 will be available for preorder in black and white color options on August 9th before shipping on August 23rd. The headphones are priced at $349.95, which is $50 less than the Momentum 3 when it debuted in 2019.
