Can AirPods 4 cancel noise?
Yes, the higher-end AirPods 4 model includes Active Noise Cancellation, Adaptive Audio, and Transparency mode. The open-fit design uses a vent system to reduce pressure while still cancelling ambient noise.
What is Adaptive Audio?
- Adaptive Audio intelligently blends ANC and Transparency based on your environment (Apple Newsroom)
- It adjusts in real time, reducing noise when you’re in a loud setting and letting sound through when someone speaks nearby
This means you get the right level of isolation without constantly switching modes manually. The H2 chip processes audio at 480 million operations per second to make those adjustments.
How does Transparency mode work?
- Transparency mode uses external microphones to pipe in outside sound so you stay aware of your surroundings
- Conversation Awareness – a new feature on AirPods 4 – lowers volume and boosts voices when you start speaking (Apple Newsroom)
Unlike some competitors that offer transparency only with ear tips, AirPods 4 deliver it through an open fit, making the pass-through audio feel more natural.
Noise cancellation performance in real-world scenarios
- Testing by Recording Now (hands-on review) found that the AirPods 4 ANC cancels low-frequency sounds like engine hum and air conditioning effectively
- Higher-pitched sounds like traffic noise and people talking are reduced but not eliminated, typical for open-fit ANC
The trade-off: you get less passive isolation than in-ear designs, but the vent system prevents that plugged-up sensation. For commuting on a bus or working in a coffee shop, the ANC is effective enough to lower background din without making you feel cut off.
For anyone used to sealed ear tips, this open-fit ANC is a trade-off – you get less pressure but also less isolation. The vent system relieves the “pop” sensation some listeners dislike, but it also means constant noise like traffic won’t disappear completely.
The implication: AirPods 4 ANC are best for users who want ambient awareness more than total silence. If your priority is drowning out everything around you, the AirPods Pro 2 or a pair of over-ear headphones still lead.
How do I activate noise cancelling on AirPods?
You can switch between ANC, Transparency, and Off in three ways: using the stem force sensor, through Control Center on your iPhone or iPad, or in Settings.
Using Control Center on iPhone
- Open Control Center, then touch and hold the volume slider until you see the listening mode controls (Apple Support)
- Tap the Noise Cancellation icon (a ear icon with a sound wave) to switch modes
- The current mode is shown under the volume bar
Using Settings app
- Go to Settings > Bluetooth and tap the “i” icon next to your AirPods 4
- Under the “Noise Control” section, select your preferred mode
- You can also customize which modes the force sensor cycles through in this menu (Apple Support)
Using the stem force sensor
- Press and hold the stem on either AirPod until you hear a chime – each press cycles to the next mode in your selected sequence
- By default, the cycle is ANC → Transparency → Off
- You can change the order and which modes are included in Settings > Bluetooth > AirPods “i” > Accessibility > Button Cycles Between (Apple AirPods User Guide)
What this means: once you set your preferred cycle, the stem press becomes a fast toggle. No need to pull out your phone for a mode change.
If you use AirPods 4 on a Windows laptop or Android device, the force sensor still works – but you need to preset the cycle on an Apple device first.
The catch: without an Apple device for initial configuration, you cannot change the listening mode cycle.
How to tell if noise cancelling is working on AirPods?
Several cues confirm ANC is active, and a few checks can help if it seems weak.
Check status in Control Center
- When ANC is on, the volume slider in Control Center shows a small noise cancellation icon
- You can also ask Siri: “Is noise cancellation on?” – she’ll reply with the current mode
Listen for ambient noise reduction
- The biggest tell: low-frequency hums (fans, engine noise, air conditioning) drop noticeably when ANC engages
- If there’s no change, try re-seating the AirPods or checking that both earbuds are firmly in your ears
Verify firmware version
- Outdated firmware can cause poor ANC performance. Check your firmware in Settings > General > About > AirPods (Apple Support guide)
- The latest firmware as of writing is version 6B34 – automatic updates happen when AirPods are charging and within Bluetooth range of an Apple device
A crackling or popping sound may indicate a hardware issue – if cleaning the mesh doesn’t help, contact Apple Support.
Do AirPods 4 have the double tap feature?
No. Apple replaced the double-tap gesture with a force sensor on the stem, starting with the AirPods Pro. Here’s how the controls work instead.
What gestures are available on AirPods 4?
- Single press: play/pause music or answer a call
- Double press: skip forward
- Triple press: skip back
- Press and hold: cycle between listening modes (ANC, Transparency, Off) (Apple Support)
How to customize touch controls
- Open Settings > Bluetooth > tap “i” next to your AirPods 4
- Under Accessibility, you can adjust Press Speed (how fast you must press) and Hold Duration (how long to hold for the mode switch)
- You can also assign the press-and-hold to Siri instead of noise control if you prefer
The pattern: Apple unified the control scheme across AirPods models, so muscle memory transfers between AirPods 4 and AirPods Pro 2.
Why are people ditching AirPods?
While AirPods 4 have strong features, some users move away for reasons that matter to know before you buy.
Battery degradation concerns
- Lithium-ion batteries in AirPods naturally lose capacity over time – some owners report noticeably shorter battery life after 12–18 months of daily use
- AirPods batteries are not user-replaceable; Apple charges £79 for out-of-warranty replacement per earbud
Fit issues with open design
- The open-fit design doesn’t create a seal, so people with smaller ears may find the AirPods feel loose
- Without a seal, ANC effectiveness drops because ambient noise leaks in around the edges
- If you’re sensitive to that, AirPods Pro 2 with silicone ear tips are more secure (Recording Now review)
Price compared to competitors
- AirPods 4 with ANC cost £179 / $179 – same as the AirPods Pro 1 used to cost
- Competitors like the Sony WF-1000XM5 (premium earbuds) offer deeper ANC and longer battery life, though at a higher price
Health tangents: can ANC trigger tinnitus?
- Some users report that the pressure-venting sensation of open-fit ANC can feel disorienting at first, but no clinical evidence ties ANC to causing tinnitus
- On the contrary, using ANC at moderate volumes can reduce overall noise exposure, which may help protect hearing over time
The catch: AirPods 4 ANC aren’t for everyone. If you value maximum noise cancellation or a snug fit, the AirPods Pro 2 or competitors like the Bose QuietComfort Earbuds are better bets. But for comfort and awareness, the open-fit design has a clear audience.
AirPods 4 ANC vs AirPods 4 vs AirPods Pro 2
Three models, three levels of isolation. Here’s how they stack up:
| Feature | AirPods 4 (no ANC) | AirPods 4 (with ANC) | AirPods Pro 2 |
|---|---|---|---|
| Active Noise Cancellation | No | Yes (Adaptive, Transparency, Conversation Awareness) | Yes (same features plus adaptive transparency) |
| Chip | H2 | H2 | H2 |
| Battery (single charge) | 5 hours | 4 hours (ANC on) / 5 hours (ANC off) | 6 hours (ANC on) / 7 hours (ANC off) |
| Total with case | 30 hours | 20 hours (ANC on) / 30 hours (ANC off) | 30 hours (ANC on) / 36 hours (ANC off) |
| Fit type | Open-fit (no ear tips) | Open-fit (no ear tips) | In-ear with silicone tips (XS, S, M, L) |
| Water resistance | IPX4 | IPX4 (earbuds) / IP54 (case) | IPX4 (earbuds) / IP54 (case) |
| Price | $129 / £129 | $179 / £179 | $249 / £249 |
The pattern: AirPods 4 ANC sit in a middle ground – you get the core ANC features of the Pro model but in a lighter, more breathable shape. The trade-off is battery life and maximum noise reduction.
