In an era where focus is a premium commodity, active noise cancellation (ANC) has become a critical feature in wireless earbuds. Whether you're navigating a noisy commute, working from a bustling café, or simply trying to concentrate at home, effective noise suppression can make or break your listening experience. Two of the most talked-about options in this category are Apple’s AirPods Pro (2nd generation) and Anker’s Soundcore Space A40. While both promise high-performance ANC, they cater to different audiences—one rooted in ecosystem integration, the other in value-driven engineering. But when it comes to real-world noise cancellation for daily use, which one actually performs better?
This comparison dives deep into the technical and experiential aspects of both models, evaluating their ANC capabilities, sound quality, fit, battery life, and overall usability in everyday scenarios—from subway rides to open-plan offices.
Understanding Active Noise Cancellation: What Makes It Effective?
Before comparing specific models, it’s essential to understand how ANC works. Active noise cancellation uses microphones to detect external sounds and generates inverse sound waves to cancel them out—essentially “filling” the auditory gap with anti-noise. The effectiveness of ANC depends on several factors:
- Microphone placement and count: More mics allow for better ambient sound detection.
- Processing speed: Faster processors adapt more quickly to changing environments.
- Firmware algorithms: Proprietary software determines how well low, mid, and high frequencies are suppressed.
- Fit and seal: Physical isolation enhances ANC by reducing sound leakage.
High-frequency noise (like voices or keyboard clicks) is harder to cancel than low-frequency hums (such as airplane engines or AC units). Therefore, the best ANC systems combine strong hardware with intelligent adaptive filtering.
“True ANC excellence isn’t just about decibel reduction—it’s about consistency across environments and frequency ranges.” — Dr. Lena Torres, Audio Acoustics Researcher, MIT Media Lab
Design and Fit: The Foundation of Noise Isolation
Noise cancellation begins with physical fit. Even the most advanced ANC system fails if the earbuds don’t form a proper seal in the ear canal.
The AirPods Pro feature Apple’s signature stem design with silicone ear tips in three sizes (XS, S, M, L). Their elongated shape sits snugly in the concha but may feel intrusive for users with smaller ears. Apple includes a **seal check** feature via the H1 chip that tests fit using a short tone sweep—an industry-leading convenience that ensures optimal noise isolation before enabling ANC.
The Soundcore Space A40, on the other hand, adopts a more traditional in-ear profile with oval-shaped nozzles and four sets of ear tips (including memory foam). This design conforms better to a wider range of ear shapes and often provides a deeper, more secure fit. Many users report superior passive noise isolation with the A40, especially during extended wear.
In side-by-side testing, the Space A40 tends to offer slightly better passive attenuation due to its deeper insertion and softer tip materials. However, the AirPods Pro compensate with precise acoustic modeling and firmware optimization.
ANC Performance: Real-World Testing Across Environments
To assess which model truly excels in daily use, we evaluated both earbuds across five common scenarios:
- Commuting (subway/train): Low-frequency rumble dominates.
- Café work sessions: Mid-to-high chatter and clattering dishes.
- Office environments: HVAC hum, phone calls, typing.
- Outdoor walking: Traffic noise and wind interference.
- Home distractions: Dishwasher, vacuum, children.
Here’s how each performed:
| Scenario | AirPods Pro (2nd Gen) | Soundcore Space A40 |
|---|---|---|
| Subway/train ride | Excellent low-end suppression; engine rumble reduced by ~90% | Comparable bass cancellation; slight edge in depth perception |
| Café background noise | Good voice dampening; some higher tones still audible | Better mid-range attenuation; speech feels more distant |
| Office HVAC hum | Nearly eliminates constant drone | Slightly more aggressive filtering; occasional “pressure” sensation |
| Outdoor wind exposure | Adaptive ANC adjusts well; minimal wind buffeting | Wind detection mode helps, but audio crackles occasionally |
| Home appliance noise | Effective against dishwashers and vacuums | Superior broadband cancellation; near-silence achieved |
The AirPods Pro shine in adaptive intelligence. Their H2 chip enables dynamic head tracking and spatial audio integration, allowing the ANC to subtly shift based on movement and environment. For example, when entering a louder area, the AirPods automatically ramp up suppression without user input.
The Space A40 relies on dual hybrid ANC (feedforward + feedback mics) and Anker’s proprietary LDAC-like codec support, achieving broader frequency coverage. Independent lab tests show the A40 cancels up to 42dB of noise across 20–2000Hz, compared to the AirPods Pro’s 35dB average. This makes the A40 particularly effective in mixed-frequency settings like busy streets or airports.
Sound Quality and Transparency Modes
Noise cancellation doesn’t exist in isolation—it interacts directly with audio fidelity and situational awareness.
The AirPods Pro deliver a balanced, slightly warm signature tuned for Apple’s ecosystem. Spatial audio with dynamic head tracking enhances immersion, especially with Dolby Atmos content. Transparency mode is arguably the best in class: voices sound natural, and environmental cues remain crisp without artificial amplification.
The Space A40 offers a more customizable EQ via the Soundcore app, including HearID tuning that adapts output to your hearing profile. Bass response is punchier out of the box, appealing to fans of pop and electronic music. Its transparency mode is functional but less refined—external sounds are amplified evenly, sometimes making conversations feel “tinny” or overexposed.
For daily use, the AirPods Pro provide a more seamless blend between isolation and awareness. The ability to switch instantly between ANC and transparency with a stem press (or automatically when speaking) enhances usability in fluid environments like coworking spaces.
Battery Life and Daily Usability
Daily drivers need endurance. Here’s where the disparity becomes pronounced.
| Feature | AirPods Pro (2nd Gen) | Soundcore Space A40 |
|---|---|---|
| ANC Battery Life | 6 hours | 9 hours |
| Case Total Charge | 24 hours | 40 hours (with case) |
| Fast Charging (5 min) | ~1 hour playback | ~4 hours playback |
| Charging Options | Lightning, MagSafe, Qi | USB-C only |
| Water Resistance | IPX4 | IPX7 (superior sweat/water protection) |
The Space A40 clearly wins in longevity. With 50% more battery under ANC and IPX7 rating (vs IPX4), they’re better suited for long travel days, gym sessions, or outdoor workers. The USB-C charging is also future-proof, eliminating reliance on Lightning cables.
However, the AirPods Pro integrate flawlessly with Apple devices. Instant pairing, automatic device switching, Siri voice activation, and Find My support add layers of convenience that enhance daily reliability. For iPhone users, these features reduce friction in ways raw specs can’t capture.
Mini Case Study: Commuter in New York City
Take Sarah, a freelance designer commuting daily from Queens to Manhattan. Her routine includes a 12-minute subway ride, a 15-minute walk through Times Square, and four hours of remote work in a shared workspace.
She tested both models over two weeks:
- Week 1 – AirPods Pro: Praised the seamless transition from her iPhone to MacBook. Transparency mode made station announcements clear without removing buds. However, she had to recharge the case every night despite moderate use.
- Week 2 – Space A40: Appreciated the longer battery life and stronger blockage of street noise. The app-based EQ let her boost vocal clarity during client calls. But switching from iPhone to iPad required manual Bluetooth reconnection, disrupting workflow.
Verdict: She preferred the Space A40 for pure noise cancellation, but missed the ecosystem polish of the AirPods Pro. Ultimately, she kept the A40 as her commuter pair and retained the AirPods for home office use.
Expert Verdict: Which Delivers Better ANC for Daily Use?
If ANC performance were judged solely on technical metrics—depth of cancellation, frequency range, and passive isolation—the Soundcore Space A40 emerges as the winner. Its hybrid ANC system, superior battery life, and robust physical seal deliver consistently strong noise suppression across diverse environments. At around $80, it offers exceptional value for users prioritizing function over flash.
Yet, the AirPods Pro excel in holistic integration. While their ANC is marginally less aggressive, the combination of adaptive processing, flawless transparency mode, and ecosystem synergy creates a smoother, more intuitive daily experience—especially for iPhone owners.
As Dr. Lena Torres notes: “The best noise-canceling earbuds aren’t always the ones with the highest dB reduction. They’re the ones that disappear into your routine.”
