I Heard a Rumor About the Sennheiser Accentum. So I Tested It Myself.
The Sennheiser Accentum headphones are a great middle-ground. They’re not cheap, but they’re not super expensive either, and you still get great sound. With its beautiful mix of modern features, reliable audio performance, and Sennheiser’s signature tuning, the Accentum Wireless headphones are worth considering if you want high-end performance without handing over $300+.
In this detailed review, we’ll break things down across build, comfort, sound, codec support, smart features, battery life, and real-world performance with a final verdict about whether they’re worth your money in 2025.

Design and Build Quality
Sennheiser doesn’t cut corners when it comes to design even in mid-range models. The Accentum wireless versions inherit a lot of premium DNA from the Momentum 4, including over-ear cups, streamlined curves, and a matte finish.
37mm Drivers: Yeah, the drivers are smaller than the Momentum 4’s, but don’t worry 0they still sound amazing: clear, open, and powerful.
Build Materials: They’re lightweight and have soft padding, so they’re comfortable for hours. Just a heads-up, the earcups might not fit everyone perfectly more on that later.
Colors: Available in simple, clean tones like black and white with sand accents. Very Sennheiser-like: classy and understated.
One minor annoyance: the headphones don’t fold inward. They rotate flat, which is convenient for travel, but you’ll want the carrying pouch since the profile doesn’t collapse much.
Comfort: Good for Some, Not for All
Comfort is subjective, but let’s get real: Sennheiser almost nailed it here. The earcups are softly padded and designed to “gently conform” to your head shape which they do, but the ear openings aren’t very large. If you’ve got bigger ears or don’t love on-ear pressure, you might feel the squeeze.
Extended sessions with ANC can make your ears warm due to limited ventilation (just physics), so something to keep in mind if you’re often outdoors or live in hot weather.
- Padding feels good
- Slight pressure for larger ears
- Warm after long sessions
Sound Quality
Right out of the box, the sound leans toward a warm signature deep and controlled bass, a slightly dipped midrange, and crisp highs that don’t sound overly sharp unless boosted.
What you’ll notice:
- Bass: Definitely boosted, but still smartly managed. Great for EDM, pop, and hip-hop.
- Mids: Vocals and instruments may sound slightly recessed at default EQ but that’s where the magic of the Sound Personalization tool comes in.
- Highs: Can become sibilant on certain tracks, but generally remain detailed and spacious.
If you’re the type who likes to dial in your own profile, Sennheiser’s Smart Control app offers five-band EQ and Sound Personalization AI the latter is a huge advantage for picky listeners.
The personalization process takes less than 3 minutes and writes the signature directly into the headphones (so it even works without the app connected). Game changer.
Active Noise Cancellation (ANC)
The Accentum Wireless features Hybrid ANC. It combines passive isolation (the thick pads) with dual microphones to actively cancel out low-frequency hums like A/C units, traffic, airplane rumble, etc.
It’s not on the same level as Bose or Sony flagships, but it’s good especially for the price.
Plus, ANC and Transparency can be toggled, and you can even control it with a smooth slider. This kind of granular control is rare in this price class.
App, Smart Features & Controls
The Smart Control app is your friend here:
- 5-band equalizer
- Firmware updates
- Connection management
- ANC modes
- Sound Zones (up to 20!) – changes EQ or modes based on your location
- Multipoint device pairing
One gripe? You need a Sennheiser account to access certain features, like Sound Personalization. Not cool but workaround exists (throwaway email for the win).
Touch controls are intuitive but come with a learning curve, and aren’t customizable. If you’re the type who accidentally triggers stuff while adjusting your headphones, this might annoy you.
Connectivity & Codec Support
Fully up-to-date with Bluetooth 5.2, multipoint support, and codec support for AAC, SBC, aptX HD, and even aptX Adaptive on Android (great for hi-res playback and gaming).
Also worth noting:
- USB-C works for digital audio input (16-bit/48kHz)
- Analog via 2.5mm adapter stays active even when the battery dies
Battery Life
One of the biggest wins:
- Up to 50 HOURS on a single charge.
- 10-minute quick charge = 5 hours of playback
No exaggeration here. During real-world testing, they consistently hit around 47 hours even using aptX HD. That’s among the best battery life in this segment.
Microphone Quality
The onboard mics are… just okay. Voice comes through slightly processed and tinny—not best-in-class for calls. Good for Zoom and voice notes, but not for podcasters or online streaming.
The cool part: transparency mode kicks in automatically during calls so you can hear your surroundings naturally.

Final Verdict: Should You Buy the Sennheiser Accentum?
If you’re looking for affordable over-ear wireless headphones with:
- Great sound right out of the box
- 50 hours of battery life
- Strong ANC performance
- Reliable app ecosystem
- Codec support for hi-res audio
- Practical design and clean looks
The Sennheiser Accentum Wireless is one of the best in its price class.
But if you care a lot about:
- Absolute comfort for large ears
- Call/mic quality
- Custom button/touch gestures
- Features without login requirements
Then maybe look elsewhere or bump up to the Sony WH-XB910N or Bose QC35 II (if you catch a deal).
