A dramatic update and upgrade over the previous generation, the black MOMENTUM 4 Noise-Canceling Wireless Over-Ear Headphones from Sennheiser trades in the classic design and folding body for a sleeker, more modern look and fold-flat earcups. More importantly, the battery life has drastically improved by nearly four times to up to 60 hours with both Bluetooth and adaptive noise cancellation on. Audio quality is still on the high end with Sennheiser's Signature Sound powered by large 42mm drivers. Sound can easily be customized to your individual hearing with the Sennheiser Smart Control app. Add in clear calls from four beamforming mics with wind-noise suppression, and you have a pair of headphones that can be used throughout your entire day.
