The Sony WH-1000XM4 is one of the most popular and highly-regarded noise-cancelling headphones on the market. With its advanced noise-cancelling technology and sleek design, it’s no wonder that many people swear by them. However, some users have reported that they can still hear external noise while wearing the headphones, which can be frustrating and confusing. If you’re one of them, you’re not alone. In this article, we’ll delve into the reasons why you might still be able to hear with noise-cancelling Sony WH-1000XM4 headphones and what you can do to optimize their performance.
Understanding Noise Cancellation Technology
Before we dive into the reasons why you might still be able to hear with the Sony WH-1000XM4, it’s essential to understand how noise-cancelling technology works. Noise cancellation, also known as active noise control or active noise reduction, is a technology that uses one or more microphones to capture ambient noise, and then produces a “negative” sound wave to cancel it out. This results in a quieter listening experience with less external noise interference.
The Sony WH-1000XM4 uses a proprietary noise-cancelling technology called Noise Cancellation Algorithm, which uses a combination of microphones and advanced signal processing to identify and cancel out ambient noise. This technology is designed to adapt to various noise environments, such as airplane noise, background chatter, and traffic sounds.
Types of Noise and How Noise Cancellation Works
There are two types of noise that noise-cancelling headphones can tackle: constant noise and sudden noise. Constant noise refers to steady, ongoing sounds like the hum of an engine or the rustling of leaves. Sudden noise, on the other hand, refers to abrupt, intermittent sounds like a car horn or a door slamming.
Noise-cancelling headphones use two primary methods to cancel out noise:
- Passive Noise Isolation: This involves using materials like foam or rubber to block out noise physically. Passive noise isolation is effective against high-frequency sounds like metal clinking or high-pitched conversation.
- Active Noise Cancellation: This involves using microphones to capture ambient noise and produce a “negative” sound wave to cancel it out. Active noise cancellation is effective against low-frequency sounds like engine rumble or airplane noise.
Why You Might Still Hear with Noise-Cancelling Sony WH-1000XM4
Now that we’ve covered the basics of noise-cancelling technology, let’s explore some reasons why you might still be able to hear with the Sony WH-1000XM4:

A proper fit is essential for effective noise cancellation. If the headphones don’t fit snugly around your ears, external noise can seep in and compromise the noise-cancelling effect. Make sure to try different ear tips or adjust the headband to achieve a comfortable, secure fit.
Environmental Factors
Environmental factors like wind, background chatter, or loud music can overpower the noise-cancelling technology. If you’re in a particularly noisy environment, it may be challenging for the headphones to cancel out all the noise. Try to find a quieter spot or adjust the noise-cancelling setting to compensate for the ambient noise.
Volume Level
If you’re listening to music at very low volumes, you may still be able to hear external noise. Try increasing the volume to a comfortable level to mask out the ambient noise.
Audio Content
The type of audio content you’re listening to can also impact the effectiveness of noise cancellation. For example, if you’re listening to music with a lot of high-frequency content like treble-heavy tracks, you may still be able to hear external noise. Try switching to music with more balanced frequency response or using noise-cancelling settings optimized for speech or music.
Technical Limitations
While the Sony WH-1000XM4 is an excellent noise-cancelling headphone, it’s not perfect. There are technical limitations to how well noise-cancelling technology can perform.

Why can I still hear external noise with noise-cancelling headphones on?
Noise-cancelling headphones, including the Sony WH-1000XM4, are not designed to completely eliminate external noise. Instead, they use advanced noise-cancelling technology to reduce ambient sounds, making it easier to focus on the audio you want to hear. While they can significantly reduce external noise, they may not block out every single sound.
The type of noise that can still be heard through noise-cancelling headphones often depends on the frequency and volume of the sound. For example, high-frequency sounds like screams or sirens may still be audible, while low-frequency sounds like rumbling engines or airplane noise may be more effectively blocked out.
How do noise-cancelling headphones work?
Noise-cancelling headphones use a technology called active noise control or active noise reduction. This involves placing one or more microphones on the headphones that capture ambient noise, and then producing a “negative” sound wave to cancel it out.
