In a sea of wireless earbuds promising crisp audio, active noise cancellation, and all-day comfort, Sennheiser’s CX Plus True Wireless earbuds continue to hold a steady place in the market—even in 2025. Launched as a step-up from the popular CX True Wireless, the CX Plus aimed to deliver a refined experience with the addition of ANC (Active Noise Cancellation), aptX support, and a customizable EQ via the Sennheiser Smart Control app.
But do these earbuds still deliver in 2025? After using the Sennheiser CX Plus True Wireless for over a year, here’s an honest, in-depth look at how they hold up today—across sound quality, comfort, battery life, connectivity, and overall value.
Sound Quality: Still Signature Sennheiser
One of the strongest reasons to invest in the CX Plus is Sennheiser’s well-established reputation for sound engineering. That promise holds true here. Even in 2025, the earbuds offer detailed mids, rich bass, and crisp highs that make everything from hip hop to classical sound immersive and enjoyable.
Unlike many budget or mid-range earbuds that crank up bass at the expense of clarity, the CX Plus maintains balance across frequencies, letting vocals breathe and instruments shine. Long-term use reveals just how versatile they are. Whether you're streaming Spotify, listening to podcasts, or watching movies, these earbuds deliver a consistently high-quality experience.
Active Noise Cancellation (ANC): Good, Not Great
The CX Plus True Wireless features hybrid ANC, and while it’s not on par with Sony’s WF-1000XM5 or Apple’s AirPods Pro (2nd Gen), it does a solid job in everyday scenarios. It noticeably reduces low-end rumbles—like the sound of a train or air conditioning—but doesn’t completely block out higher-pitched voices or sudden noises.
That said, Passive Noise Isolation is excellent, thanks to the snug fit of the silicone ear tips. Combined with ANC, it’s more than sufficient for commutes, offices, and light travel. Long-term users will appreciate that the ANC hasn't degraded or caused connection issues—something some other brands struggle with over time.
Comfort and Fit: Secure for Long Listening
Earbuds are only as good as their comfort, and the Sennheiser CX Plus scores high in this area. With multiple sizes of silicone tips, most users can find a fit that seals well without causing ear fatigue. As someone who uses them for several hours a day, I’ve found the fit to be both secure and comfortable, even during walks or light workouts.
They're a bit larger than some newer ultra-compact earbuds in 2025, but that size contributes to better battery life and housing the robust drivers. The ergonomics are spot-on—no ear soreness, even after long listening sessions.
Battery Life: Reliable for Daily Use
Even a year later, the battery performance hasn’t faltered. Sennheiser claims up to 8 hours on a single charge (with ANC off) and 24 hours total with the case—and that claim still checks out.
In real-world usage with ANC on and moderate volume, I typically get around 6.5 to 7 hours per charge, which is still competitive with many newer earbuds. The charging case uses USB-C (no wireless charging, unfortunately), but charges fairly quickly and holds enough juice for two full recharges.
In short, battery degradation hasn't been an issue after a year of use, which speaks to the build quality and power management.
Controls and Connectivity: Responsive and Reliable
The touch controls on the Sennheiser CX Plus are fully customizable via the app, and they’ve remained responsive throughout long-term use. You can assign different gestures to each earbud, covering volume, playback, ANC toggle, and voice assistant activation.
Bluetooth connectivity is where these earbuds continue to impress. Featuring Bluetooth 5.2, the connection is rock solid—even in crowded areas. Pairing is fast, and I’ve rarely experienced audio drops or syncing issues. The support for aptX and AAC means Android and iPhone users both enjoy good codec coverage.
For calls, the dual mics in each earbud handle voice quite well in quiet and semi-noisy environments. You won’t sound studio-perfect, but it’s more than sufficient for Zoom calls and hands-free conversations.
Build Quality and Design: Understated but Durable
One of the understated wins for the CX Plus is the build quality. The matte plastic case and earbuds feel premium, and after over a year of tossing them into backpacks and gym bags, there are no major scratches or mechanical issues. The IPX4 rating adds protection against sweat and light splashes, which is enough for day-to-day use or workouts.
In 2025, many earbuds lean into flashy aesthetics or ultra-minimalism. The CX Plus’s clean, subtle design makes them an attractive choice for users who want performance without the showiness.
App Experience: Improved Over Time
The Sennheiser Smart Control app has matured since its release. It’s now more stable, with smoother EQ adjustments, firmware updates, and battery indicators. It doesn’t overload users with options, but provides just enough customization to make the earbuds your own.
Over the past year, Sennheiser has pushed regular firmware updates, improving connection stability and minor bugs—a sign they haven’t abandoned the product, which matters in today’s fast-moving tech world.
Value for Money: Even Better in 2025
Here’s the big one: Are the CX Plus worth buying in 2025?
The answer is yes—especially now that they’re often available at lower prices than their original RRP.
With newer earbuds entering the market, you can now find the CX Plus for under AUD $200 or even lower during sales. At this price, the value they offer—premium sound, decent ANC, customizable controls, strong battery life—is hard to beat.
If you’re after a mid-range true wireless earbud that still competes with newer models in all the areas that matter, the CX Plus remains a smart buy.
Final Verdict
After using the Sennheiser CX Plus True Wireless for over a year, I can confidently say they’ve aged well. In 2025, they still offer:
- Excellent sound quality true to Sennheiser’s heritage
- Reliable ANC and great passive isolation
- Comfortable, secure fit for long-term use
- Long battery life and strong Bluetooth connectivity
- A maturing app with ongoing support
While they may lack premium features like spatial audio or wireless charging, those trade-offs are minor considering the current pricing.
