What ENC is and how it is different from ANC in earbuds?

In the world of earbuds and headphones, two terms that often come up are ENC and ANC. While both technologies aim to enhance audio experiences by reducing unwanted noise, they operate in different ways and cater to different needs. Understanding the distinctions between ENC and ANC can help you make an informed decision when selecting your next pair of earbuds.

What is ENC?

Environmental Noise Cancellation (ENC) is a feature primarily designed to improve the clarity of voice calls. Unlike Active Noise Cancellation, which focuses on overall noise reduction, ENC specifically targets background noise during calls.

It uses multiple microphones to pick up ambient sounds and then processes these sounds to filter out any noise that could interfere with the clarity of your voice. This makes ENC particularly useful in noisy environments, such as crowded public places or busy offices, ensuring that your conversations are clear and uninterrupted.

What is ANC?

Active Noise Cancellation (ANC), on the other hand, is a more comprehensive technology aimed at reducing ambient noise in general. ANC earbuds use microphones to detect external sounds and then generate sound waves that are the exact opposite (or “anti-noise”) to cancel out the unwanted noise. This process, known as phase inversion, effectively reduces the perception of external sounds, allowing you to enjoy your music or podcasts with minimal distraction. ANC is particularly beneficial for travellers, commuters, or anyone who spends a lot of time in noisy environments.

Key differences between ENC and ANC

The primary difference between ENC and ANC lies in their purpose and application. ENC is focused on improving the quality of voice calls by filtering out background noise, while ANC is designed to reduce ambient noise for a better listening experience. ENC enhances call clarity by processing incoming and outgoing sounds, making it ideal for those who frequently take calls in noisy settings. ANC, on the other hand, offers a broader range of noise reduction, enhancing overall audio enjoyment by creating a quieter environment.

Advantages and limitations of ENC and ANC

Both technologies come with their own set of advantages and limitations. ENC is excellent for clear voice communication but may not significantly impact your listening experience during playback. It excels in scenarios where you need to be heard clearly over background noise. ANC, conversely, provides a more immersive listening experience by reducing overall ambient noise, but it may not address voice call clarity as effectively as ENC.

In summary, both noise cancellation features are valuable in modern earbuds, each serving a distinct purpose. ENC is ideal for enhancing call quality in noisy environments, while ANC provides a quieter, more immersive audio experience for various listening activities. By understanding these technologies, you can choose the earbuds that best fit your needs, whether you prioritise clear calls or a noise-free listening experience.
