The Sennheiser ACCENTUM Wireless are the more affordable sibling of the top-of-the-line wireless Sennheiser MOMENTUM 4 Wireless. While their noise cancelling (ANC) won't blow you out of the water, they still have handy features like aptX support for higher-quality audio streaming, a companion app with a graphic EQ and presets, and multi-device pairing. They also have a long-lasting continuous battery life that exceeds that of competitors like the Anker Soundcore Space Q45 Wireless.

Our Verdict

7.4 Neutral Sound

The Sennheiser ACCENTUM are decent for neutral sound. They have a bass-heavy sound out of the box that delivers extra thump, rumble, and boom to mixes. Vocals and instruments sound present but lack detail due to a dip in the treble range. You can adjust their sound to suit your needs using their companion app's graphic EQ and presets.

Pros
  • Graphic EQ and presets available.
Cons
  • Poor passive soundstage performance.
7.3 Commute/Travel

The Sennheiser ACCENTUM are decent for commute and travel. They have a decently comfortable fit and have a long-lasting continuous battery life that will endure through many hours on the go. They also have an ANC system, but it struggles to reduce the low rumble of bus and plane engines. Unfortunately, the headphones also lack a carrying case to keep them safe.

Pros
  • ANC does an excellent job of reducing mid to treble range noise.
  • Decently comfortable.
Cons
  • ANC struggles to block out the low rumble of bus engines.
  • Bulky and can fall off of your head while moving.
7.2 Sports/Fitness

The Sennheiser ACCENTUM Wireless are over-ear headphones, which aren't the best choice for sports and fitness. They can easily shift in positioning or even fall off while you're moving. They also lack an IP rating for water resistance, but that's normal for over-ears.

Pros
  • Decently comfortable.
Cons
  • Bulky and can fall off of your head while moving.
7.3 Office

The Sennheiser ACCENTUM are decent for office use. These decently comfortable over-ears support multi-device pairing, so you can stay connected to your PC and smartphone simultaneously. Thanks to their ANC system, they can also block out a fair amount of ambient sound around you, like chatty coworkers and the hum of AC units. They also have a long continuous battery life, so you don't need to worry about charging them after a long day at work.

Pros
  • ANC does an excellent job of reducing mid to treble range noise.
Cons
  • Poor passive soundstage performance.
5.8 Wireless Gaming

The Sennheiser ACCENTUM are Bluetooth headphones; their latency is high enough to interrupt your gaming.

7.1 Wired Gaming

The Sennheiser ACCENTUM are satisfactory for wired gaming. They only support a wired USB connection, but if that's alright with you, they have fairly low latency and support audio as well as mic usage. They have a bassy sound, making games with explosions sound more rumbly. Their mic also offers a fair overall performance, so your teammates and enemies will hear you clearly.

Pros
  • Alright overall microphone performance.
Cons
  • Poor passive soundstage performance.
6.8 Phone Calls

The Sennheiser ACCENTUM are okay for phone calls. Their integrated mic does a fair overall job, and can capture your voice, so that you're intelligible. Your voice won't get fully drowned out by loud sounds from a busy office either, but vocal quality takes a hit. The headphones are equipped with an ANC system to help block out background sounds. While it struggles to block out the low rumble of bus engines, it does a better job of cutting down ambient chatter and the hum of AC units.

Pros
  • ANC does an excellent job of reducing mid to treble range noise.
  • Alright overall microphone performance.
Cons
  • ANC struggles to block out the low rumble of bus engines.
  • Bulky and can fall off of your head while moving.

Differences Between Sizes And Variants

The Sennheiser ACCENTUM Wireless come in two color variations: 'Black' and 'White'. We tested the Black model, and you can see its label here and here. Since the difference is purely cosmetic, both variants will perform similarly. If you come across another variant of these headphones, please let us know in the forums, and we'll update our review.

Compared To Other Headphones

The Sennheiser ACCENTUM are mid-range wireless headphones. They're quite similar to the Sennheiser MOMENTUM 4 Wireless and even have many of the same features as their higher-end counterpart, but their overall performance isn't as good. Their ANC system doesn't block out as much ambient sound as the budget-friendly Anker Soundcore Space Q45 Wireless, though, and they don't have analog support, though you can use them via wired USB.

Check out our picks for the best wireless Bluetooth headphones, the best headphones under $200, and the best noise cancelling headphones under $200.

Sennheiser MOMENTUM 4 Wireless

The Sennheiser MOMENTUM 4 Wireless headphones are more premium than the Sennheiser ACCENTUM Wireless. The MOMENTUM 4 are more comfortable, better built, and have a more neutral sound out of the box, which some users may prefer. Their ANC system can also block out more background noise, they last longer on a single charge, and support aptX Adaptive, which is a Bluetooth codec that dynamically adjusts its performance to your content. That said, the ACCENTUM are still a decent option, particularly if you're on a smaller budget. They have most of the same features as the MOMENTUM 4 but don't perform quite as well overall.

Sony WH-1000XM4 Wireless

The Sony WH-1000XM4 Wireless are better headphones than the Sennheiser ACCENTUM Wireless. The Sony are more comfortable, are more premium in build, and have a significantly better noise isolation performance. You can also use them wired via analog, which some users may prefer. The Sennheiser have a longer continuous battery life, though, and support aptX, which can help give you better sound quality than the default SBC codec.

Anker Soundcore Space Q45 Wireless

The Anker Soundcore Space Q45 Wireless have the edge over the Sennheiser ACCENTUM Wireless. The Anker are more comfortable, have a significantly better noise isolation performance, and support LDAC, which is Sony's proprietary codec for streaming audio in higher resolutions. However, the Sennheiser have a more neutral sound out of the box, and their continuous battery life is longer.

Bose QuietComfort 45/QC45 Wireless

The Bose QuietComfort 45/QC45 Wireless are more premium headphones than the Sennheiser ACCENTUM Wireless. The Bose are more comfortable and have a more neutral sound out of the box, which some users may prefer, and their noise isolation performance is significantly better, too. However, the Sennheiser have a longer continuous battery life.

These headphones have a similarly sleek and non-descript look as the Sennheiser MOMENTUM 4 Wireless. They have a one-color design with a plastic headband and hinges. The manufacturer's logo is embossed on the headband. They come in two color variants: 'Black' and 'White'.

These headphones are decently comfortable. The ear cups are easy to adjust, and they have plush padding. However, the same can't be said for the headband; its padding doesn't feel particularly great, and it's only built into the top of the band, so if you have a large head, your head can rub against the ends of the headband, which don't have padding at all. The headphones also have a high clamping force, so wearing glasses can cause the tops of the ear cups to press the arms into your head. If you have large ears, they can touch the back side of the ear cups, and you may even have trouble getting a good seal if you have a large head.

Build Quality

The build quality is good. These headphones don't feel quite as premium as the Sennheiser MOMENTUM 4 Wireless, as they're made of plastic and faux leather. You need to make sure that the earpad seal is well attached to both ear cups; otherwise, you'll experience a difference in audio quality and ANC performance. Even glasses can make a difference, as the arms can disrupt the ear cups' padding on your head. You can see a photo of what an incorrect ear pad seal looks like here. The headband extension is a smooth slider, but it feels like it can wear away with time.

Stability

The stability of these headphones is decent. They'll stay on your head if you listen to audio at your desk or walk to work. However, if you're wearing them while running, they can easily move around your head or even fall off your head.

The Sennheiser ACCENTUM have a bass-heavy sound profile. They deliver extra thump and rumble, which is good for genres like EDM and hip-hop. That said, while vocals and instruments are present in mixes, they're a bit veiled and lacking in detail due to a dip in the low-treble. Luckily, their companion app offers a graphic EQ and presets to help you adjust their sound to your liking.

The frequency response consistency of these over-ears is satisfactory. They're prone to minor inconsistencies in bass and treble delivery. You may especially notice a drop in bass if you have thick hair or wear glasses. As a result, it's important to take the time to adjust their fit, positioning, and seal each time you use them.

These headphones have mediocre treble accuracy. Most of the treble range is underemphasized. Vocals and instruments like those in Simon & Garfunkel's song The Sound of Silence are very veiled and lacking in detail. Sibilants like cymbals are also dull.

Peaks/Dips
Peaks

Dips
1.69 dB

The peaks and dips performance is satisfactory. The headphones struggle to control their sound profile in a couple of places. A bump in the low-bass adds extra thump and rumble to mixes, while a slight dip in the high-bass lowers boom. A peak in the high-mid affects the left driver a bit more than the right, which makes vocals and instruments harsh. A dip in the low-treble weakens these sounds like a steep peak in the mid-treble makes sibilants piercing.

The imaging performance is great. Sennheiser usually shows high-quality control and ergonomics across all of the products we've tested; these are no exception. It's worth noting that imaging performance can differ across units, though. Our unit's L/R drivers are well-matched in amplitude, frequency, and phase response, ensuring accurate placement of sound objects like voices in the stereo image. That said, they have a bit of trouble with low-bass in their group delay. This causes a loose bass, particularly in bass-heavy tracks. There's also a small peak in the phase response's low-mid, which causes a slight reduction of the soundstage. However, this is very difficult to notice with real-life content.

The passive soundstage is poor, but that's normal for closed-back headphones. Their soundstage isn't very immersive-sounding, as audio feels like it's coming from inside your head rather than from speakers placed in the room around you. The soundstage also feels closed-off and unnatural but wide.

The Sennheiser ACCENTUM's battery performance is excellent. The manufacturer advertises the battery to last up to fifty hours continuously, although we measured less than that. Battery life varies depending on usage and features like taking calls or ANC. Luckily, they're equipped with an auto-off timer to help conserve battery life when not in use. You can't use them passively since they don't support analog, but you can use them while they're charging. Their USB cable lets you stream audio and use their mic, so long as they have a charge.

You can also access a wind reduction setting that's enabled separately from the ANC, and there are sound zones you can customize, which dynamically adapt their sound and noise isolation performance to your location. However, you'll need an account to access the sound zone feature.

These headphones have great Bluetooth connectivity. They support multi-device pairing, so you can connect them to your PC and smartphone simultaneously, and you can see which codec you're using via their companion app. They have high latency via SBC and aptX codecs, so your audio and visuals will be out of sync. AptX is designed to give you better sound quality than SBC, so if you're only using it to listen to audio, you won't notice latency. Some devices compensate for latency. Like the Sennheiser MOMENTUM 4 Wireless, they don't support aptX Adaptive or LDAC either, which is disappointing if you want to stream higher-quality audio beyond what aptX can provide.
