The new Sennheiser Momentum True Wireless 4, Accentum Plus and Momentum Sport earbuds made their debut at CES 2024.

The Momentum True Wireless 4 earbuds deliver unparalleled sound with connectivity built on the Qualcomm S5 Sound Gen 2 platform and Snapdragon Sound Technology for aptX lossless sound quality and ultra-low latency. The Bluetooth 5.4 earbuds bring Auracast support and an overhauled antenna design for signal continuity while on the go, supported by improved Adaptive ANC, evolved tuning, and an upgraded battery system.

The fourth-gen Momentum buds boast 7.5 hours of continuous listening, a Qi charging case, and quick charging over USB-C. They will be available in three colours: black copper, metallic silver, and graphite for $499.95.

The new Accentum Plus Bluetooth 5.2 headphones prioritise sound quality, battery life and versatile connectivity, supporting popular codecs including aptX Adaptive with up to 50 hours of listening time per charge. A touch-enabled earcup—also used in the flagship Momentum series—offers intuitive feature control.

Multipoint connectivity, wind-reduction and adjustable side-tone complement Adaptive ANC which optimises its noise target to constantly adjust to the ambient noise environment. An audio cable is included to tap into in-flight entertainment systems or other headphone outputs, which can be stowed away in the included travel case. Accentum Plus will be available in black and white for $399.95.

The new Momentum Sport true wireless earbuds have been optimised for fitness with the integration of a photoplethysmography (PPG) heart rate sensor and a body temperature sensor that can output data to popular fitness apps and devices.

For the first time in a non-Polar product, users can enjoy full access to Polar’s elite biosensing capabilities and data analytics including body temperature, offering real-time insights during training and deeper offline analysis via the Polar Flow app ecosystem.

To minimise footstep noise, breathing, and other body-borne distractions, the earbuds feature an acoustic relief channel and semi-open design for natural environmental awareness. An adjustable transparency mode, anti-wind mode, and Adaptive Noise Cancelling (ANC) mode let the wearer adapt as surroundings change.

The all-new acoustic system features a redesigned transducer that delivers the best sound quality yet in a Sennheiser sport earbud. Thanks to IP55 sweat and water resistance, a shock-proof chassis, and clog-resistant ear tips, Momentum Sport are built to withstand any workout. The IP54-rated, Qi-enabled carrying case stores up to three additional earbud recharges, extending playback time from up to six hours to 24 total hours. Momentum Sport will be available polar black, burned olive and metallic graphite for MSRP $529.95.
