Overview
Sennheiser’s Accentum True Wireless earbuds sit below the Momentum line as a midrange offering priced at a suggested 199.90 euros, though they were available for 139.90 euros at the time of testing. They come in black, blue, and the white review unit.
In the roughly 150–200 euro bracket, the Accentum competes with the likes of Huawei FreeBuds Pro 4, JBL Live Beam 3, Apple AirPods 4, and Google Pixel Buds Pro 2, so the field is crowded and expectations are high.
Design and Comfort
Sennheiser focused on ergonomics. The Accentum earbuds use 7 mm drivers of Sennheiser’s own design and ship with four sizes of silicone tips to help users find a comfortable fit. The box also includes a USB-A to USB-C charging cable and documentation.
The earbuds are noticeably comfortable in long sessions. Thanks to the range of tips and the shape tuned in collaboration with parent-company Sonova, they do not press or fatigue the ear even after hours of use. That comfort is the Accentum’s standout quality.
Comfort comes with a tradeoff. The Accentum earbuds do not anchor as securely as some rivals. They handle casual jogging fine, but more vigorous activity like jump-roping can dislodge them. Fit varies by ear shape; while they sat well in my larger ears, smaller ears may not enjoy the same seal, which can affect both comfort and sound.
Connectivity and Battery
The Accentum uses Bluetooth 5.3 and supports Bluetooth LE Audio and Auracast. Codec support includes SBC, AAC, aptX, and LC3. The earbuds carry an IP54 splash resistance rating, so they can handle running in light rain.
Sennheiser rates battery life at up to eight hours per charge with ANC off and 28 hours total including the charging case. With ANC enabled, the earbuds are rated for about six hours per charge. Real-world use matched those claims closely. The case charges over USB-C and supports Qi wireless charging. Ten minutes of fast charge yields roughly one hour of listening time.
Sound and Active Noise Cancellation
Sound from the Accentum is balanced and generally pleasant without dramatic coloration. Where many budget and midrange buds push bass hard, the Accentum stays measured; the low end can come across slightly restrained but not thin. These are not high-end audiophile cans, but they deliver solid performance for a sub-200-euro package.
The active noise cancellation sits squarely in the midrange. It effectively reduces low-frequency noise such as engine rumble, while higher-frequency sounds bleed through more easily. ANC introduces a slight hiss even when no audio is playing, which may bother very sensitive listeners using the buds purely as passive earplugs. ANC also affects the tonal balance to some degree.
There is a wind mode intended for outdoor use that helps suppress wind noise that typically challenges ANC, though it cannot eliminate loud gusts completely.
Controls and App
ANC, transparency, and EQ settings are available in Sennheiser’s Smart Control app. The app includes a customizable equalizer and allows adjustment of the transparency (ambient) mode. Transparency tends to emphasize higher frequencies.
Touch controls are implemented as tap gestures. Left tap toggles the transparency mode; right tap pauses playback. Double taps skip forward or back. Triple taps can switch ANC modes or summon the phone’s voice assistant. Long presses adjust volume, and tap controls can answer calls. Pairing a new source is done by holding both touch surfaces simultaneously.
The touch controls work reliably, though the design means accidental taps can happen when you push the buds deeper into the ear, which can be annoying in day-to-day use.
Call Quality and Latency
Microphone performance is adequate but not outstanding. Calls work without major issues, yet the mic quality is well short of the best in class.
Latency is noticeably high and can be distracting when watching video or gaming.
Build and Case
The charging case closes magnetically. It stays shut in a bag or pocket during normal commuting, but a drop to the floor can send the earbuds flying out. Overall finish is fine but leans plastic in feel.
Verdict
Sennheiser Accentum True Wireless delivers a comfortably worn earbud with balanced sound and competent ANC. Its strengths are comfort and an even sound profile, while its weaknesses include less secure fit for sports, middling microphone quality, and higher latency.
At the full 199.90 euro tag the Accentum faces tough competition, but the reduced 139.90 euro price makes the package considerably more compelling.
