1. Noise Cancelling Technology

Noise Cancelling refers to technology that reduces or eliminates external noise. Primarily found in headphones and earbuds, it's used to enhance music listening experience and improve call quality by creating a quieter environment.
There are two main types of noise cancelling:

Active Noise Cancelling (ANC)

Active Noise Cancelling uses sound wave interference to cancel out noise. When you see "Noise Cancelling" in product descriptions, this is typically what it refers to.
How it works: Uses microphones and inverse sound waves to cancel out noise.

Built-in microphones detect ambient noise, generate inverse sound waves, and play them back to cancel out the noise.
Features: Particularly effective against low-frequency sounds. Requires power (battery) as it uses electronic circuits.

ANC implementation varies by product.
High-quality models often use a dual-layer structure with external and internal microphones - external mics pick up ambient sound while internal mics detect noise. Lower-priced models typically use single microphones.

Therefore, the number of microphones is an important consideration when reviewing product specifications.
Some products also feature transparency mode, which analyzes ambient sound in real-time and allows you to hear your surroundings naturally while wearing the earbuds.

Passive Noise Cancelling (PNC)

How it works: Uses physical barriers to block external sound. Operates purely through physical means without any electronic components. This is a basic concept that's good to be aware of.

2. How to Choose Noise Cancelling Earbuds

Let's explore the key points to consider before introducing specific noise cancelling earbuds.

Key Considerations

When looking at products labeled with noise cancelling, it's important to check what types of sounds and environments they can effectively cancel. While budget is a factor, products with multiple microphones and transparency mode tend to offer higher quality.

Since Active Noise Cancelling (ANC) consumes significant power, look for models with 4-8+ hours of playback time. While Sony's "WF-1000X" series is a benchmark in Japan, we'll introduce some high-performance, cost-effective alternatives.

EarFun Air Pro4

These earbuds feature noise cancelling technology that can reduce noise by up to -50dB across frequencies up to 5000Hz. While these numbers might be hard to grasp, imagine it as effectively cancelling a wide range of sounds from high to low frequencies! Each earbud is equipped with four microphones.

Edifier Neobuds Pro2

These earbuds feature noise cancelling technology that can reduce noise by up to -50dB across frequencies up to 5000Hz. While these numbers might be hard to grasp, imagine it as effectively cancelling a wide range of sounds from high to low frequencies! Each earbud is equipped with four microphones.

Anker Soundcore Liberty 4 Pro

The company adopts its own Ultra Noise Cancelling 3.5 technology, which uses adaptive technology and multiple microphone configurations to provide next-generation noise cancelling performance.

3. Tips for Making the Most of Noise Cancelling Technology

Usage Scenarios While On the Move

Noise cancelling earbuds are convenient when moving around. For example, during commutes or on public transportation, you can block out surrounding noise and immerse yourself in your favorite music or podcast. It can also help reduce airplane engine noise and car noise, making travel more comfortable.

By utilizing the noise cancelling feature in these environments, you can effectively block external sounds and create your own space. Especially for Bluetooth earbuds with high-performance ANC (Active Noise Cancelling), you can enjoy a comfortable usage experience even when moving.

Comfort Tips for Extended Use

Comfort during extended use is a big factor in choosing earbuds. Not only is the fit feeling good, but also the lightweight design is important. Additionally, factors such as ventilation and material feel affect comfort. Models with soft silicone ear tips that fit well and provide stability are good for your ears.

In addition, if the ANC feature is built in, you can reduce the burden on your ears by adjusting the effect as needed.

Battery Management and Charging Guidelines

Battery management is very important when using noise cancelling with Bluetooth earbuds. Since ANC consumes a lot of battery, even high-performance models may feel short playback time depending on usage.

Before extended use, make sure to charge the earbuds and charging case properly. Also, look for models that support quick charging, which allows for use in a short time.

For example, choose models with sufficient playback time when ANC is on.

Adjusting ANC Based on Noise Levels

It's important to use the noise cancelling feature appropriately according to the actual noise situation. For example, ANC is effective for certain low-frequency noise on trains or airplanes, but it's convenient to switch between the transparency mode and external sound pickup mode in environments with irregular noise like cafes or offices.

Recently, some hybrid ANC models automatically select the optimal mode according to the change in environment. Also, it's recommended to turn off ANC and save battery when the noise is not too intense.
