Sennheiser Signature Sound

At the heart of MOMENTUM True Wireless 4 is Sennheiser's acclaimed TrueResponse acoustic system, featuring precision-engineered 7mm dynamic transducers. These high-performance drivers deliver impactful bass, natural midrange reproduction and refined high-frequency detail for a balanced and immersive listening experience.

With a frequency response extending from 5Hz to 21kHz and total harmonic distortion below 0.08%, the earbuds reproduce music with exceptional clarity, precision and dynamic expression.

Adaptive Hybrid Active Noise Cancellation

Advanced adaptive hybrid ANC continuously responds to changing environmental noise, helping reduce distractions in busy offices, public transportation, airports and other demanding listening environments.

The adaptive system automatically adjusts noise cancellation to suit surrounding conditions, allowing listeners to remain immersed in their music without constantly changing settings.

High-Resolution Wireless Audio with aptX Lossless

MOMENTUM True Wireless 4 supports advanced Bluetooth audio codecs including aptX, aptX Adaptive, aptX Lossless, AAC, SBC and LC3.

With a compatible source device, aptX Lossless enables lossless-quality wireless audio transmission, preserving musical detail and clarity. Bluetooth 5.4 provides modern wireless connectivity, while LE Audio technology and Auracast support expand compatibility with emerging wireless audio applications.

Auracast Broadcast Audio

Auracast technology allows compatible devices to receive shared Bluetooth audio broadcasts, opening new possibilities for wireless listening in supported public and personal environments.

MOMENTUM True Wireless 4 supports Auracast through compatible firmware, providing access to next-generation Bluetooth broadcast audio features as they become available.

Personalized Sound with Smart Control

The Sennheiser Smart Control app provides extensive audio customization through Sound Personalization, an adaptive five-band equalizer, Sound Check, Sound Zones and selectable sound modes.

Sound Personalization uses guided listening tests to create an audio profile tailored to individual hearing preferences. The equalizer allows further adjustments to bass, midrange and treble, while Sound Zones can apply preferred settings for different listening environments.

Up to 30 Hours of Battery Life

MOMENTUM True Wireless 4 provides up to 7.5 hours of playback from the earbuds with ANC disabled, or up to 7 hours with ANC enabled. The included charging case extends total listening time to approximately 30 hours.

Fast charging provides up to one hour of playback from just eight minutes of charging. The case supports both USB-C charging and convenient Qi wireless charging.

Clear Calls with Six Microphones

Each earbud incorporates three MEMS microphones, providing a total of six microphones across the system. Advanced beamforming technology helps isolate speech and reduce unwanted background noise for clearer communication.

This microphone system supports hands-free calling and voice communication in a variety of environments, including offices, public spaces and outdoor locations.

Comfortable and Secure Fit

The ergonomic earbud design is engineered for extended listening comfort. Four sizes of soft silicone ear adapters and three sizes of ear fins allow users to customize the fit for different ear shapes and listening activities.

A secure fit also helps maintain consistent acoustic performance and passive noise isolation, supporting the effectiveness of the adaptive ANC system.

IP54 Dust and Splash Resistance

The earbuds feature an IP54 protection rating, providing resistance to dust and water splashes. This makes them suitable for everyday commuting, exercise and use in changing weather conditions.

The IP54 rating applies to the earbuds only and does not extend to the charging case.

Smart Connectivity and Everyday Convenience

Bluetooth 5.4 connectivity supports modern wireless audio features and reliable connections with compatible smartphones, tablets and other Bluetooth devices.

The Sennheiser Smart Control app provides access to sound settings, firmware updates and personalized listening functions, helping keep the earbuds optimized for everyday use.
