Sennheiser ACCENTUM True Wireless Earbuds (Blue)

The Sennheiser ACCENTUM True Wireless is an in-ear true wireless earbud finished here in Blue. It is built around Sennheiser’s 7 mm TrueResponse dynamic driver, developed with the acoustic approach used across the brand’s audiophile range, and adds hybrid active noise cancelling, Bluetooth 5.3 with LE Audio and Auracast support, and up to 28 hours of total battery life with the charging case. The earbud shape was developed using ergonomic modelling based on thousands of ear scans, and four sizes of silicone ear tips are included so the fit can be matched closely to your ears.

Key features

• 7 mm TrueResponse dynamic driver with 5 Hz to 21 kHz response
• Hybrid active noise cancelling with Transparency mode
• Up to 8 hours per charge, up to 28 hours total with the case
• Bluetooth 5.3 with LE Audio and Auracast, plus aptX and LC3 codecs
• Four beamforming microphones, two per earbud, for calls
• IP54 splash resistance for the earbuds
• USB-C and Qi wireless charging for the case

Sound

The single 7 mm TrueResponse dynamic driver in each earbud covers a specified frequency response of 5 Hz to 21 kHz, with a maximum sound pressure level of 107 dB at 1 kHz. The tuning follows Sennheiser’s house approach: clear, detailed and balanced, with bass that is present without overwhelming vocals and instruments. Codec support covers SBC, AAC, aptX and LC3, so higher-quality wireless playback is available from compatible phones and players. The Sennheiser Smart Control app adds a five-band equaliser, presets and a sound personalisation feature that adapts the response after a guided listening test, and settings are stored for repeat listening.

Noise cancelling and calls

Hybrid active noise cancelling combines feed-forward and feedback microphones to reduce surrounding noise, which helps on public transport, in aircraft cabins and in busy offices. Battery figures reflect this: playback is up to 8 hours with noise cancelling off and up to 6 hours with it on. Transparency mode passes outside sound through when you need to hear an announcement or hold a brief conversation. For calls, two beamforming MEMS microphones per earbud, four in total, focus on your voice and reduce background noise, with a microphone frequency response of 100 Hz to 10 kHz. Either earbud can be used on its own for calls or listening.

Fit, design and durability

Each earbud weighs 5.5 g, and the complete set with the charging case weighs 52 g. Four ear tip sizes, XS, S, M and L, are supplied, and choosing the right size matters for both comfort and the effectiveness of the noise cancelling seal. Touch controls on the earbuds handle playback, calls, noise cancelling modes and voice assistant access, and the control layout can be customised in the Smart Control app. The earbuds are rated IP54, giving protection against dust and splashing water, which covers workouts and light rain. The compact case is light, pocketable and easy to carry through the day.

Battery and connectivity

The earbuds hold a 55 mAh battery each and the case holds 420 mAh, giving up to 20 additional hours for up to 28 hours in total. A 10-minute charge adds about 1 hour of listening, and a full earbud recharge takes about 1.5 hours. The case charges over USB-C and also supports Qi wireless charging. Bluetooth 5.3 operates in Class 1, and support for Bluetooth LE Audio and Auracast prepares the earbuds for shared and broadcast audio sources as they become more widely available.

In Blue, the ACCENTUM True Wireless brings Sennheiser’s TrueResponse driver, hybrid noise cancelling and a carefully shaped fit together in a compact everyday earbud with app-based sound personalisation.
