How to Turn On Noise Cancellation: A Complete Guide for Every Device
Noise cancellation has gone from a premium airline perk to a standard feature on earbuds, headphones, laptops, and even smartphones. But "turning it on" looks completely different depending on what you're using — and understanding why helps you actually get the most out of it. 🎧
What Noise Cancellation Actually Does
Before diving into steps, it's worth knowing what you're activating. Active Noise Cancellation (ANC) works by using tiny microphones on your device to pick up ambient sound, then generating an inverted sound wave that cancels it out before it reaches your ears. This is different from passive noise isolation, which is just physical blocking — like foam ear tips creating a seal.
Most consumer devices today use ANC, and many also layer in Transparency Mode (sometimes called Ambient Mode), which does the opposite — it lets outside sound in. These two modes often share the same toggle or button.
Turning On Noise Cancellation by Device Type
On Wireless Earbuds and Headphones
This is where most people are starting. The steps vary by brand, but the common methods are:
- Physical button or touch gesture — Many earbuds use a long-press or tap sequence on the earbud itself to cycle through modes: ANC → Transparency → Off. Check your device's quick-start guide for the exact gesture.
- Companion app — Brands like Sony, Bose, Apple, Samsung, and Jabra all have dedicated apps (Sony Headphones Connect, Bose Music, etc.) where you can toggle ANC, adjust its intensity, and customize gestures.
- Voice assistant or device settings — Some headphones allow ANC control through Alexa or Google Assistant commands.
Battery drain note: ANC draws additional power. Activating it will reduce playback time, typically by 20–40% depending on the device. This is a real trade-off to factor in.
On iPhone (iOS)
Apple's ANC features live in a few different places depending on which product you're using:
- AirPods Pro / AirPods Max: With your AirPods in and connected, go to Settings → [Your AirPods name] and set the Noise Control mode to Active Noise Cancellation. You can also press and hold the AirPods stem (Pro) or the Digital Crown (Max) to cycle between modes.
- During a phone call: iOS automatically offers noise reduction on calls. This is separate from ANC and works through microphone processing, not the ANC hardware.
On Android Devices
Android doesn't have a universal noise cancellation toggle because ANC is hardware-dependent. However:
- For connected headphones/earbuds: Use the manufacturer's companion app (Google Pixel Buds app, Samsung Galaxy Wearable, etc.) or pull down your Quick Settings panel — some Android versions surface ANC as a tile when compatible headphones are connected.
- For phone calls: Many Android phones include microphone noise suppression in call settings. Look under Settings → Calls → Noise Reduction or similar — the exact path varies by manufacturer and Android skin (Samsung One UI, Pixel UI, MIUI, etc.).
On Windows PCs and Laptops
Windows handles noise cancellation primarily through microphone settings, not speaker output:
- Go to Settings → System → Sound → Microphone and select your input device, then look for Noise Suppression or Enhancements options.
- Some laptops (Dell, HP, Lenovo) include proprietary software like Dolby Atmos, DTS Sound Unbound, or manufacturer audio suites that add ANC-style microphone filtering.
- Windows 11 introduced Voice Clarity — a built-in noise suppression feature for microphone input that can be toggled under accessibility or audio settings on supported hardware.
On Mac
- For microphone noise reduction during calls or recordings, many apps (Zoom, Teams, FaceTime) handle this internally with their own settings.
- macOS itself doesn't expose a system-wide ANC toggle, but third-party apps like Krisp or NVIDIA RTX Voice (on compatible systems) can apply software-based noise suppression to your microphone input.
The Variables That Determine What You'll Experience
Knowing how to turn it on is just the first step. How well it works — and whether it works at all — depends on several factors:
| Variable | Why It Matters |
|---|---|
| Hardware quality | ANC performance varies significantly across price tiers |
| Fit and seal | Poor ear tip seal dramatically reduces ANC effectiveness |
| Frequency of noise | ANC excels at low, constant sounds (engines, AC); struggles with sudden or high-pitched sounds |
| Firmware version | Manufacturers frequently improve ANC algorithms through updates |
| Companion app version | Some ANC settings only appear in newer app versions |
| OS compatibility | Some ANC features are only available with specific OS + device combinations |
Software-Based vs. Hardware-Based Noise Cancellation
This distinction matters more than most people realize.
Hardware ANC (dedicated chips and microphones in headphones) processes sound in real time with very low latency. It works regardless of what device you're connected to.
Software ANC (apps like Krisp, or OS-level features) runs on your computer's CPU and applies filtering to microphone input. It's more flexible and doesn't require special hardware, but it adds processing load and may introduce slight audio artifacts. 🔊
Some setups use both — a headset with hardware ANC for playback, plus a software layer for cleaner microphone output on calls.
When Noise Cancellation Doesn't Work as Expected
Common reasons ANC underperforms:
- The feature is disabled in the app, even if the button was pressed
- Firmware is outdated — check for updates in the companion app
- Wrong ear tips — if the seal isn't tight, the microphones can't accurately sample ambient sound
- The noise type isn't well-suited to ANC — voices, irregular sounds, and high frequencies are harder to cancel than engine hum or HVAC noise
Some devices also have adaptive ANC, which adjusts automatically based on your environment. This can be toggled on or off separately from ANC itself.
Whether noise cancellation delivers a subtle improvement or a dramatic transformation depends heavily on your specific hardware, how you're wearing it, what environment you're in, and which software stack sits between the microphones and your ears. Each of those layers is worth examining in your own setup before assuming the feature isn't working — or before assuming it's working as well as it could. 🔍
