Sennheiser Accentum Plus: Is the Upgrade Worth It?

Although the Accentum Plus has undergone modifications and added some new features, it is not a substantial improvement from the original Accentum released last year.

Less than four months after unveiling the mid-range Accentum headphones, Sennheiser released an upgraded version at CES – the Accentum Plus. Priced at $230, $50 more than its predecessor, the Accentum Plus offers touch controls, revised active noise cancellation (ANC), wear-detection, and other conveniences. But are the internal updates enough to justify the higher cost?

Design: Familiar but Lacking

At first glance, the Accentum Plus looks strikingly similar to the original Accentum. The primary difference lies in the absence of physical buttons in the Plus version. Instead, all audio and call controls are touch-based, located on the outside of the right ear cup. While functional, some users may prefer the physical controls on the older model. Another difference is that the Accentum Plus includes a 3.5mm aux jack in addition to the USB-C connection found in the first Accentum.

One disappointment is that Sennheiser has not addressed the usage of plastic in the majority of the headphone’s construction. The plastic build gives them a cheap look and feel, which is unexpected for headphones in this price range. Sennheiser introduced a new design style with the Momentum 4 headphones, which are more refined compared to both Accentum models.

Software and Features: App-Driven Personalization

The Sennheiser Smart Control App offers similar features for both the Accentum and the Accentum Plus. The app provides battery percentage, connection management for multipoint Bluetooth, and audio customization. Users can adjust a five-band EQ, select sound presets, and utilize Sound Personalization that calibrates the audio based on individual responses. The app also includes Sound Zones, allowing users to configure specific audio settings for different locations.

ANC control is also accessible through the app, enabling users to adjust the level of noise cancellation and transparency. However, the ability to activate specific blends of noise cancellation and transparency is missing. Overall, the app offers a range of features, but users may need to grant permission for location tracking, which may be a concern for some.

Sound Quality: Crisp and Dynamic, but with Limitations

Sennheiser is known for providing exceptional sound quality with its flagship earbuds and headphones, and the Accentum Plus is no exception. The audio profile is well-tuned, delivering dynamic tones and fine detail with excellent clarity across the EQ. The sound quality is most impressive at around 65-75 percent volume. However, at lower volumes, the bass begins to overpower some of the details, and the audio profile becomes muddied.

While the Accentum Plus performs well across most genres, more chaotic styles like metal may experience some loss of finer details in guitars and drum textures. The overall performance can feel compressed compared to other headphones. On the other hand, with mellow tracks, the Accentum Plus shines, providing a truly immersive listening experience.

ANC Performance: Marginal Improvements

Sennheiser claims that the Accentum Plus features hybrid adaptive ANC, while the regular Accentum only has hybrid ANC. Despite this claim, the difference in ANC performance between the two versions is minimal. The ANC performance of the Accentum Plus is solid in most circumstances, but it falls short compared to industry leaders like Bose and Sony. Given the higher price tag of the Plus version, one would expect more noticeable improvements in ANC.

Call Quality: Acceptable, but Not Exceptional

The Accentum Plus performs adequately for calls, although the audio quality is not pristine. It is sufficient for everyday use, including work calls; however, for important presentations, a headphone with a better microphone would be advisable. The voice quality may appear compressed and slightly tinny. Unlike more expensive options like the AirPods Max, the Accentum Plus does not pipe in the user’s voice, resulting in less natural overall audio quality.

Battery Life: Impressive Endurance

The Accentum Plus offers a battery life of 50 hours, matching the regular Accentum. During testing, it exceeded this figure, providing up to 57 hours of use with ANC enabled. Quick charging capabilities are also notable, with just 10 minutes of charging providing five hours of listening time. The battery life of the Accentum Plus is impressive and is one of its standout features.

The Competition: Decisions, Decisions

Considering the marginal upgrades in the Accentum Plus, it is difficult to recommend them over the more affordable Accentum. Both models offer Sennheiser’s signature crisp and clear sound, with the ANC improvements of the Plus version not being significant enough to warrant the higher price. For those seeking affordable noise-canceling headphones, the Sony WH-CH720N may be a better option. Priced at $105, it offers good audio quality and comfort, although its noise cancellation capabilities are average.

Conclusion: Not a Significant Upgrade

Sennheiser’s attempt to enhance the mid-range Accentum with the Accentum Plus falls short of expectations. While the sound quality and ANC performance are decent, the improvements are not remarkable enough to justify the higher price tag. The better-than-expected battery life is undoubtedly a positive aspect, but that same endurance can be found in the regular Accentum for $50 less. To make a more substantial impact, Sennheiser should have implemented design refinements and made more noticeable upgrades to audio quality and ANC performance.
