Disclosure: The Accentum True Wireless was provided by Sennheiser for the purpose of this review. Please read more about our product review disclosure here.

The Sennheiser Accentum True Wireless earbuds are the mid-range offering from Sennheiser in their True Wireless lineup, placed between their high-end offering the Momentum True Wireless 4 (which I recently reviewed, and they have become my favorite wireless earbuds to date!) and the budget offering in the CX True Wireless. The Accentum TW shares many of the same features as the Momentum TW4, just cut down a bit, so let’s see how much it affects the overall experience.

Earbuds

The Sennheiser Accentum True Wireless earbuds look like something akin to a hearing aid. They are made out of smooth plastic and look fairly bland overall, with the etched Sennheiser logo on the outside of each earbud barely visible.  Thankfully, the earbuds are very lightweight and feel solidly built. The Accentum TW comes with four soft silicone ear tip sizes, which also feature a mesh to prevent any debris from getting into the earbud’s nozzle. The earbuds fit comfortably in my ears and feel secure, allowing me to use them for runs and exercises, as well as leisurely walks without the need to worry about them falling out. They’re also IP54 rated, meaning exposure to light rain or sweat shouldn’t harm them. I have one complaint about the earbud design, which is the touch controls, but I’ll elaborate further in the touch controls section.

Charging Case

The charging case features the same plastic and overall feeling as the earbuds. It feels sturdy, the magnetic hinge is strong and feels satisfying to open and close, and the case is also very light at just 41g (compared to 66g for the MTW4). I also appreciate the size of the charging case, which was one of my main complaints about the Momentum True Wireless 4, meaning I can fit the charging case for the Accentum True in my jeans pocket without it protruding too much. The case itself has no buttons and has a USB-C port for charging. You can also charge the case wirelessly.

Touch Controls

Like the Momentum TW4, the Accentum True Wireless is operated by touch controls on the outside of each earbud. By default, the controls on each earbud perform different functions but can be entirely customized in the Smart Control app.

The one issue I have with the touch controls is tied to the design of the earbuds. The earbuds are small and narrow enough that it is almost impossible not to accidentally activate them when putting them in or removing them from your ears. I had the same issue with the Momentum True Wireless 4, but the design of those earbuds is a bit chunkier so it was easier to grip them with my fingers without activating the controls. For the Accentum TW, unless you’re very careful, you will almost always activate the controls when handling them.

Overall, the Accentum True Wireless earbuds are nicely designed and are comfortable, but look on the boring side. The charging case works very well and has a portable footprint. The sensitivity of the touch controls is the only annoyance here for me.

Hybrid Active Noise Cancellation

The active noise cancellation system of the Accentum True Wireless features a hybrid system that features a transparency mode and an anti-wind mode. With ANC switched on the Accentum TW does a decent job of blocking most common types of noises, such as traffic sounds, trains, and office chatter. The earbuds also created a good seal on my ears for decent overall passive sound isolation, which works in tandem with the active noise cancellation. It’s definitely not as good as the ANC performance on the Sennheiser Momentum True Wireless 4, but honestly, it gets the job done.

The anti-wind mode works well, cutting down on the sound created by wind to help keep the audio you’re listening to clear.

When earbuds first started getting introduced with transparency mode, as popularised by Apple’s AirPods Pro, I could never get used to the feature. Now though it’s almost essential for me, as it means I don’t have to fiddle with taking the earbuds out in order to talk to someone or listen to an announcement. And thankfully, the transparency mode on the Accentum True Wireless works very well. It has three settings: Low, Mid, High. I found Mid to be just the most natural sounding and strikes the best balance. High tended to amplify audio too much. Low is just right for when you take phone calls.

Bluetooth Codec Support

The Accentum True Wireless support for Bluetooth codecs is fairly basic by today’s standards: SBC, AAC, and aptX. It would have been nice to get support for aptX Lossless or Adaptive, but those usually get reserved for the higher-end models.

Battery Life

Sennheiser claims that the Accentum True Wireless gets up to 8 hours of audio playback with ANC off, and 6 hours with ANC on, with 28 hours overall when you include the charging case. This is with the AAC codec mind you. In my testing using aptX, I was able to get 5 hours 40 minutes with ANC on, which is very respectable. For charging, you get an hour of playback time with a 10 minute charge, which I confirmed in my testing. Wireless charging for the case also works as expected.

Companion App

To manage the settings and firmware updates for the Sennheiser Accentum True Wireless, you need to use the Sennheiser Smart Control app. As far as companion apps go this one is actually decent, offering a good amount of customization options and features. I do find the app to be on the slower side performance-wise, sometimes lagging and taking a while to open or change views within the app. This is especially evident on lower-performing Android devices, such as some DAPs (digital audio players). Here are a few screenshots from within the app and what you can do with the Accentum TW4:

Sound Profile

The Accentum True Wireless follows a more V-shaped tuning, meaning boosted lows and highs. This gives the Accentum TW an energetic, upbeat sound that I would deem to be very accessible for most listeners. I would almost classify these as bright sounding, but thankfully without much sibilance. The bass performance is lacking a bit. At times it can be somewhat muddy and is not as well-rounded as I would have hoped given these are using the same 7mm drivers as the Momentum TW4. The mid-range has a recessed soundstage but maintains clarity, with some added warmth. What these earbuds lack in detail they make up for in fun and energy.

You can EQ the Accentum TW using the Smart Control app with various Equalizer presets, manual 5-band EQ, or create a personalized sound using the built-in sound guide. After some tinkering and even after creating a personalized EQ, I still preferred the stock sound profile overall.

Latency and Connectivity

For watching videos and playing games I’d highly recommend switching to the Low Latency codec in the app settings as it really helps keep the audio and video in sync. Otherwise, I noticed a slight delay between the audio and video on all my devices.

As far as connectivity issues go, I had none. The connection was rock solid on all devices I tested with, with no audio crackling or static present.

Microphone Performance

The Accentum TW microphone performance is average. In quiet environments, my voice was pretty clear to callers on the other end, but in noisier environments, I was told by callers on the other end that they could easily hear background noise. Wind did get filtered out pretty well, but traffic noise and train announcements came in fairly loud.

The Sennheiser Accentum True Wireless earbuds offer a compelling package for those wanting good sound quality, ANC performance, and portability but without the high-end price. The sound profile is very accessible and enjoyable, the battery performance is great, and the active noise cancellation does what it’s supposed to. For $200 USD though the competition is tight, with products such as the Nothing Ear and the Creative Aurvana Ace 2, both at $149 USD, and offer a sound profile more in line with what audiophiles would expect.

The touch control sensitivity and less-than-stellar microphone performance notwithstanding, the Accentum True Wireless offers a very good package here, just the price is $50 too high in my opinion. Audiophiles probably also won’t appreciate the sound profile here, but for everyone else, I think it will sound great. If the price goes down or they go on sale then I would definitely recommend the Accentum True Wireless if you’re in the market for true wireless earbuds.
