The Sony WH-1000XM4 is renowned for its exceptional noise-cancelling capabilities, providing an immersive listening experience that transports you to a world of calm and serenity. But despite its impressive credentials, many users have reported that they can still hear external noises while wearing these headphones. This phenomenon has sparked a flurry of questions and concerns, leaving many wondering: why can I still hear with noise-cancelling Sony WH-1000XM4?
Understanding Noise Cancellation: The Science Behind the Silence
Before we delve into the reasons behind this phenomenon, it’s essential to understand the principles of noise cancellation. Noise-cancelling headphones work by employing a clever technique called active noise control or active noise reduction (ANC). This technology uses one or more microphones to capture ambient sounds, which are then processed by an amplifier and a speaker driver. The amplifier generates an “anti-noise” signal, which is the exact opposite of the captured sound waves. When this anti-noise signal is played through the headphones, it combines with the external noise, effectively cancelling it out.
This process, although impressive, is not foolproof. Noise cancellation is most effective against constant, low-frequency sounds, such as the hum of an engine or the rumble of a plane. However, it may struggle to eliminate higher-frequency sounds, like conversations or sudden noises.
Why You Can Still Hear With Noise-Cancelling Sony WH-1000XM4: Common Explanations
Now that we’ve covered the basics of noise cancellation, let’s explore the reasons why you may still hear external noises while wearing the Sony WH-1000XM4:
Inadequate Fit
A poor fit can significantly compromise the noise-cancelling abilities of your headphones. If the earcups don’t seal snugly around your ears, external sounds can seep in, reducing the effectiveness of the noise cancellation. Make sure to adjust the headphones to fit your ears comfortably, with the earcups sitting snugly around your ears.
Insufficient Noise Cancellation
While the Sony WH-1000XM4 is an excellent noise-cancelling headphone, it’s not a miracle worker. If you’re in an extremely noisy environment, such as a construction site or a busy airport, the headphones may struggle to completely eliminate the noise. In such cases, consider combining the noise-cancelling headphones with earplugs or earmuffs for added protection.
Sound Leakage
Sound leakage occurs when sound from the headphones escapes and mixes with external noises, creating an unsettling experience. This can happen if the earcups are not sealed properly or if the headphones are not designed to handle high-volume listening. To minimize sound leakage, keep the volume at a reasonable level and ensure a snug fit.
Additional Factors: Noise Types and Volume
Two critical factors can influence the effectiveness of noise cancellation: the type of noise and its volume.
Noise Type
Noise cancellation is most effective against constant, low-frequency sounds. However, it may struggle to eliminate high-frequency sounds, such as:
- Sudden noises (e.g., car horns, door slamming)
- High-pitched conversations
- Squeaky or creaky sounds
Noise Volume
The volume of the external noise also plays a significant role in the effectiveness of noise cancellation. If the noise is extremely loud, even the best noise-cancelling headphones may struggle to completely eliminate it.

What is noise cancellation technology?
Noise cancellation technology is a process that involves the use of one or more microphones to capture ambient sound, and then producing a “negative” sound wave to cancel out the unwanted noise. This results in a quieter listening experience, allowing the listener to focus on the audio they want to hear. Noise cancellation technology is often used in headphones, earbuds, and earplugs to improve sound quality and reduce distractions.
The technology relies on the principle of destructive interference, where the out-of-phase sound wave cancels out the unwanted noise. This is achieved through the use of advanced algorithms and digital signal processing. The microphone(s) in the headphones capture the ambient sound, and then the electronics in the headphones generate an “anti-noise” signal that is the exact opposite of the ambient sound. When the anti-noise signal is played through the headphones, it combines with the ambient sound, resulting in a quieter listening experience.
How do noise-cancelling headphones work?
Noise-cancelling headphones work by using a combination of passive noise isolation and active noise cancellation. Passive noise isolation involves the physical design of the headphones, such as the ear cups and ear pads, which block out some of the ambient sound. Active noise cancellation involves the use of microphones and electronics to capture and cancel out the remaining ambient sound.
The process of active noise cancellation starts with the microphone(s) in the headphones, which capture the ambient sound. The microphone(s) send the sound signal to an amplifier and a processing unit, which analyzes the sound and generates an “anti-noise” signal. The anti-noise signal is then sent to the headphones’ drivers, which play the sound back to the listener. The anti-noise signal combines with the ambient sound, resulting in a quieter listening experience.
What are the benefits of noise-cancelling headphones?
The benefits of noise-cancelling headphones include improved sound quality, reduced distractions, and increased comfort during long listening sessions. By reducing the ambient noise, listeners can focus on the audio they want to hear, and enjoy a more immersive listening experience. Noise-cancelling headphones are particularly useful for commuters, travelers, and individuals who work in noisy environments.
In addition to improved sound quality, noise-cancelling headphones can also help reduce fatigue and stress caused by constant exposure to loud noises. By reducing the ambient noise, listeners can relax and focus on their tasks, resulting in increased productivity and better overall well-being.
