Overview

The Sennheiser Momentum 4 Wireless headphones represent a refined approach to premium portable audio, built around custom 42mm transducers that deliver Sennheiser's signature sound profile with rich detail and balanced frequency response. Supporting aptX Adaptive Bluetooth 5.2, these over-ear headphones dynamically optimize audio bitrate and latency for the best possible wireless performance from compatible devices. The accompanying Smart Control Plus app opens up deep personalization, including a parametric equalizer, sound presets, and the ability to toggle ANC and touchpad controls to match individual preferences.

Adaptive noise cancellation uses four digital beamforming microphones to intelligently block ambient sound, while a Transparency Mode lets critical external audio through when needed — a feature particularly useful for commuters and office workers. Those same microphones provide clear voice pickup during calls with wind noise suppression. At just 10.3 ounces with cushioned oval ear pads and a padded headband, the Momentum 4 is designed for extended wear, backed by up to 60 hours of battery life with fast USB-C charging. The package includes a protective carry case, USB-C cable, 3.5mm to 2.5mm audio cable for wired use, and an airplane adapter.
