Highlights & Key Technologies

Master of Sound
Experience music the way the artist intended, thanks to the outstanding fidelity of Sennheiser's TrueResponse transducer system, which lets you hear every fine detail and feel every emotion with up to 24-bit/96kHz audio resolution. Best-in-class sound quality is ensured by support for lossless audio through aptX Lossless codec, which guarantees flawless bit-by-bit transmission of audio, maintaining uncompromised sound quality during wireless listening.

Freedom from Noise and Distractions
The earbuds automatically adjust noise cancellation to your surroundings with the latest generation of Adaptive Hybrid ANC for superior noise attenuation, so there's nothing between you and your music. When you need to stay aware of your surroundings or hear others without removing your earbuds, the low-noise, natural-sounding Transparency Mode brings outside sounds back at a touch. Three microphones per earbud with beamforming array provide effective active noise cancellation even in noisy environments.

The Future of Listening
With MOMENTUM True Wireless 4, you can experience the new benchmark for incredible wireless audio and step into the future. Discover technologies that are set to revolutionize the way we share and stream audio with features such as Auracast and LE Audio. Auracast technology allows an audio signal from a transmitter to be transmitted to an unlimited number of receiving devices located within a fixed transmission radius, enabling audio data to be output to multiple devices simultaneously. Bluetooth 5.4 compatibility ensures next-generation performance and reliability for all your devices.

Designed for All Day Comfort
Thanks to MOMENTUM True Wireless 4's ergonomic design and soft silicone ear tips, you can enjoy a secure fit that feels great even over long listening sessions. Four sizes of ear adapters (XS, S, M, L) and three sizes of ear fins (S, M, L) ensure a comfortable fit for extended listening sessions. The earbuds are designed to sit comfortably and snugly in the ear canal and auricle. The Fit Test function in the Smart Control app allows you to test the fit of the earbuds in your ears.

Beyond Sound Customization
Developed in partnership with Germany's Fraunhofer IDMT, Sound Personalization intelligently calibrates a custom audio profile from a sophisticated analysis of user reactions against a series of benchmark sound samples. From there, advanced audio processing algorithms shape the listening experience around the elements of music you find most pleasing. Enjoy the simplicity of pre-set sound modes or manually fine-tune your custom sound profile with the 5-band equalizer or the easy-to-use Sound Check feature. The Sound Check function guides you step by step to the optimal result.

Extended Battery Life with Smart Charging
Stay connected, productive, and entertained throughout your day with an outstanding 30 hours of listening pleasure thanks to the new high-quality battery system. A quick charging feature provides an hour of playtime in just 8 minutes. Battery protection mode ensures gentle charging and extends battery life by charging rechargeable batteries only up to approximately 80 percent. Eco mode maximizes playback time by optimizing energy consumption and deactivating the aptX Bluetooth codec transmission, reducing transmission bandwidth while increasing operating time.\

Simple, Smart Connectivity
From automatically connecting your devices as soon as you take them out of the case, to intuitive fingertip control via the customizable touch interface, to wirelessly charging the battery case via Qi charging, advanced features and design bring a refreshingly effortless daily experience. Multipoint connectivity allows you to seamlessly switch between two connected devices for dynamic management of active connections. The earbuds can save the connection profiles of up to six Bluetooth devices with which they have been paired.

Naturally Effortless Communication
The high-quality 6-microphone system ensures you can be heard perfectly during calls even in noisy environments. Three microphones per earbud with beamforming array provide active noise cancellation and excellent voice quality for phone calls. With call virtualization you can communicate more naturally without any fatigue, as it simulates the feeling of face-to-face conversations.

Advanced Audio Modes
High Resolution Audio mode offers a full bandwidth of sound via the aptX Adaptive Bluetooth codec, with audio data compressed and transmitted with a sampling frequency of 96 kHz and a sampling depth of 24 bits. Lossless Audio mode offers maximum sound quality with audio data transmitted uncompressed and bit-accurate in CD quality via the aptX Lossless codec, with a sampling frequency of 44.1 kHz and a sampling depth of 16 bits. Low Latency mode reduces the latency between the audio and video signal to a minimum, particularly useful when streaming video on your smartphone.

Timeless Design and Sennheiser Quality
MOMENTUM True Wireless 4 matches progressive features with timeless, finely crafted design and Sennheiser quality. Available in Black Graphite, White Silver, Black Copper, Gold, and Denim, their minimalist aesthetic is elevated by premium materials such as textile and metallic finishes.

Smart Features and App Control
The Sennheiser Smart Control app allows you to use all functions and settings of the earbuds and adjust the sound to your liking. The app enables you to customize control functions for music playback, select preset control functions, or switch off control functions. You can change the language of the voice prompts, choose between voice prompts and beep sounds, or deactivate status messages with a few exceptions. Smart Pause function automatically stops music playback when you remove an earbud from the ear and continues when you insert it again. Auto Call function automatically accepts calls when you take the earbuds out of the charging case during an incoming call.

Built to Last
Sennheiser has reduced packaging footprint by 53 percent in volume and 49 percent in weight versus the first generation MOMENTUM True Wireless. Products are built to last with high qualification standards testing robustness and durability with drop tests, tumbling tests, and battery-lifetime tests. MOMENTUM True Wireless 4 are IP54 certified, splash resistant, and suitable for sports.
