Sennheiser Accentum Plus review: This could have been the ideal headphones for frequent travellers

Note: This review was first published on 1 March 2024.

The Accentum Plus is Sennheiser's more affordable wireless ANC headphone.

Lightweight, high-endurance over-ear headphones

Over the years, Sennheiser has released some great products like the Momentum True Wireless earbuds and the Momentum wireless headphones series. These all have one thing in common - the price tags are all relatively high at around SS$400-$500. 

Sennheiser clearly knows there’s a market for more affordable products as well, and we’ve seen more affordable stuff like the wired IE 200 IEMs and CX Plus True Wireless earbuds debut. This time around, they are tackling the wireless headphone segment with the Sennheiser Accentum Plus.

Before we dive in, here's our 25-second video overview right after the jump:-

The TL;DR verdict:

A decent choice for anyone who's shopping for full-featured wireless headphones on a budget. The super-long battery life is a huge plus for anyone who travels often.

Design & wearing experience

At around 227g, these headphones are pretty light and comfortable to wear.

When it comes to design, the Accentum Plus does look quite a bit like the Momentum 4 headphones with a mostly matte design scheme from the headband to the earcups. You get a shiny, silver Sennheiser logo on the sides of the headband, which isn’t too obtrusive at all. The unit I'm testing is black, but they also come in white.

The entire chassis is made with plastic, not just to keep costs down but, more importantly, to reduce weight so that it's more comfortable to wear. At 227g, it’s definitely one of the lighter headphones on the market. 

The headband is padded and covered with a silicone material, which is good for reducing possible hair tugging and the like. It’s also relatively comfortable for moderate periods of use, although I did feel some pinching at the crown and some wearing fatigue after around four to five hours.

The earpads feel plush and can be removed and replaced when they are worn out.

The earcups retain the same oval shape from before, with soft synthetic leather earpads. The earpads can be detached, so if they start to peel, they can be easily replaced. However, the earcups aren't the most cavernous, so people with larger ears might end up brushing against the insides of them.

There’s an on-ear detection sensor in the right earcup, which is incredibly sensitive, so much so that even when I was simply adjusting the position of the earcups, it would kick in and pause my music. It would be nice if the sensitivity here were dialled back a little.

Features and Usability

The headphones come with a charging cable and another cable for wired listening.

The headphones also come with a carrying case that, although soft-sided, should provide decent protection. Inside the case, there’s a USB-A to C charging cable and a 3.5mm to 2.5mm cable for wired listening. Yes, you can connect the Accentum Plus via USB-C to a source like your PC and listen to it, too.

The Accentum Plus doesn't have an official water resistance (IP) rating, which isn't surprising since these are obviously not headphones designed to be worn while exercising. Furthermore, most full-featured wireless ANC headphones don't have IP ratings either.

One disappointing design aspect of the Accentum Plus is that they don't fold. With active noise cancellation and such a long battery life, the Accentum Plus feels like it was designed to be used while travelling. Hence, not being able to fold seems like a terrible oversight since it means that they take up more space in your bag than they would otherwise have. One could argue that other headphones like the Sony WH-1000XM5 also don't fold, but that doesn't mean it's the right thing to do.

One annoying thing about these headphones is that they don't fold. This makes them less portable.

Like the Momentum headphones, most of the controls are done via a touch-sensitive panel on the faceplate of the right earcup, and we found the controls to be very intuitive. Volume controls are handled by swiping up and down, while track skipping is done by swiping forward and back. A single tap handles playback, while a double tap toggles transparency mode on or off. Most people should be able to get the hang of it after a couple of hours.

Speaking of the transparency mode, the Accentum Plus has active noise cancellation (ANC). Although it’s not quite at the same levels as some of the top noise-cancelling headphones in the market, it does a decent enough job of dampening commute noise and environmental chatter. As long as I had music playing, I wasn't too bothered by the noise that was going on around me.

The Smart Control app.You can adjust the amount of ANC you want.

The headphones connect via Bluetooth 5.2 and support multipoint connection, as well as SBC, AAC, and aptX Adaptive codecs. Like most other headphones out there, there is a companion app for these, and it’s called the Sennheiser Smart Control app – longtime Sennheiser owners should be familiar with it. It’s a simple app that shows connections, options for equalising and tweaking the sound signature, and a few other options. 

One important option that you might want to change is the option for Auto Pause when transparency mode is activated. For some reason, this is turned on by default and results in your music pausing whenever transparency is toggled on. An annoyance, but a small one, no doubt. Personally, I prefer to have my music continue playing to pick up better if the mode chosen was activated, so this was an option that I turned off very quickly after discovering this minor hassle

Battery Life and Endurance

Battery life is another huge plus for the Accentum Plus (pun intended), with a whopping 50 hours of battery life on a single charge. I used the headphones on and off for a week, and racked up about 48 hours of use, so the estimate provided by Sennheiser is spot on. To give its impressive stamina some context, 48 hours is enough to fly to non-stop to New York from Singapore and back. Even if you don't travel that extensively, not having to charge frequently is a real boon. Furthermore, a quick 10-minute charge will also provide five hours of playback time, so that’s excellent.

Audio quality

As for sound, the Accentum Plus performed decently. Clearly, the Accentum lineup is meant to bridge the gap between Sennheiser’s flagship Momentum products and the entry-level HD range. Compared to the Momentum 4, the main things I noticed were that Accentum Plus were not as crisp and detailed, and it had a less spacious soundstage. 

With sizable 37mm dynamic drivers, the Accentum Plus handled bass well with plenty of thump and a relatively commanding presence, while ensuring there’s no muddiness or boominess even at slightly louder volume levels. The mids were also nicely treated, vocals and instruments sounded rich and clear. Details were rendered accurately, and the overall sound was nicely blended together for a coherent listening experience.

Where the headphones fell slightly short was in the treble range. Even though there’s a good amount of clarity, the higher registers can feel a bit lacking when it comes to energy and sparkle. Fortunately, this can be tweaked using the equaliser in the app, so it’s not an issue.

Generally, even though the bass is a little boosted, I think that the sound signature is in line with what most consumers enjoy. People looking for a more analytical pair of headphones most likely won’t be looking at the Accentum Plus anyway, so there’s no problem here. 

Our take

On the whole, the Accentum Plus are solid headphones with decent sound, pretty good ANC, and impressive battery life. But it's not without faults. Not being able to fold seems like a terrible oversight since these headphones sound like they would be an ideal travelling companion.

However, its biggest issue is its S$349 price tag. Even though it's considerably cheaper than a Momentum 4 wireless, it's still a pretty pricey headphone. Perhaps it's inflation, but there's no question that its value proposition is questioned by the cheaper Accentum Wireless at S$249. I'm not entirely sure the Accentum Plus does enough to differentiate itself. Readers will have to evaluate their needs and make that decision for themselves. 

The Sennheiser Accentum Plus also comes in white.

In many ways, the Accentum Plus mirrors Sennheiser's own CX True Wireless. Both are attempts by Sennheiser to offer more affordable versions of their flagship products but are hamstrung by less-than-attractive pricing. If Sennheiser can bring the price of the Accentum Plus closer to or under S$300, I think they'll have a real winner on their hands (fortunately, we have a discount code below that does that). Right now, they are looking a bit pricey to me, which is a real pity because I really like using these headphones.
