Sennheiser’s True Wireless Solution lineup has been steadily growing, and the Accentum Open is the brand’s latest addition. This pair of open-ear true wireless stereo (TWS) earbuds promises the signature Sennheiser sound but takes a minimalistic approach in design and features. While it delivers on audio quality and comfort, it makes noticeable trade-offs that potential buyers should consider.

Design and Build Quality
The Sennheiser Accentum Open is made from soft plastic, giving it a lightweight feel that enhances long-term comfort. Its open-ear design eliminates silicone tips, making it less intrusive for prolonged wear. This design is particularly suitable for users who dislike the pressure or seal of in-ear buds.
The model comes in two colours cream (tested) and black. Both maintain a clean, understated aesthetic. However, the charging case could be sturdier. The hinge lacks firmness, and the lid has a tendency to shut automatically when placed on a flat surface. A more robust hinge would have been beneficial, especially for those who like to keep the case open during charging or quick access.
On the positive side, the charging case is compact and pocket-friendly, making it convenient for travel and daily commutes.
Lack of Companion App Support
One of the most noticeable omissions is the absence of a companion app. This means there is no option to:
-
Adjust the sound profile
-
Modify touch controls
-
Toggle transparency mode
While many budget TWS models now include such functionality through basic companion apps, Sennheiser has opted not to provide one for the Accentum Open. According to the company, this decision was made to enhance wireless audio stability. Still, for a product in this price range, the omission feels like a missed opportunity, particularly given Sennheiser’s expertise in combining hardware with advanced software tuning.
Audio Quality
Where the Accentum Open truly excels is in its sound performance. Even without an app to fine-tune settings, the default tuning is well-balanced. It avoids the common pitfall of being overly bass-heavy or excessively bright.
When tested with Hukum from Jailer, the earbuds presented a spacious soundstage with clear vocals and distinct layers in the instrumentation. Even subtle background vocals, such as Rajinikanth’s, were rendered with depth. Similarly, Poker Face by Lady Gaga delivered strong vocal clarity while keeping instrumental layers balanced.
Video content also benefits from the tuning. While watching the second season of FUBAR, Arnold Schwarzenegger’s distinctive baritone came through clearly, even during action sequences.
The 11 mm dynamic drivers sit outside the ear canal, reducing listening fatigue while maintaining a detailed sound profile. For first-time buyers who want great audio without manual tweaking, the Accentum Open delivers a solid out-of-the-box experience.
Features and Connectivity
The Accentum Open supports multipoint connectivity, allowing users to connect to more than one device simultaneously. Priority is typically given to the most recently connected device, as is common with multipoint setups.
Pairing is straightforward pressing both stems for three seconds initiates pairing mode. With Bluetooth 5.3, the earbuds offer stable connections and improved power efficiency.
For calls, the dual-beamforming microphones enhance voice clarity and provide basic noise reduction. During a test interview, voice transmission was reported as clear and free from significant background distractions.
Battery Life and Charging
Battery life is another strength of the Accentum Open. Sennheiser claims up to 6.5 hours of playback on a single charge, and real-world usage comes close at around 6 hours. The charging case extends total playback time to approximately 28 hours.
A quick charge feature adds convenience 10 minutes of charging provides about 1.5 hours of playback, which is useful for last-minute use. A full charge takes roughly 1 hour, making it easy to top up before heading out.

2. Can you use the Sennheiser Accentum Open for sports or workouts?

Verdict
The Sennheiser Accentum Open delivers exceptional audio quality, dependable connectivity, and long-wear comfort. However, its lack of app support, limited customization, and basic charging case design mean it lags behind some competitors like the OnePlus Buds 3 Pro or Oppo Enco X3 in terms of versatility.
If your main priorities are great sound, comfort, and ease of use without needing advanced features, the Accentum Open stands as a strong contender in its segment.
