Noise is everywhere, whether you are on the road or in a busy office. To block out daily distractions, understanding ANC vs ENC is essential before buying new headphones. Both technologies offer noise cancellation, but they solve completely different everyday problems for listeners and callers.
ANC (Active Noise Cancellation) blocks out background noise so you can hear your audio better, while ENC (Environmental Noise Cancellation) filters out surrounding sound so others hear your voice clearly. In this guide, you will learn how both work to choose the best noise-cancelling headphones for your daily routine.
Noise is everywhere, whether you are commuting through chaotic traffic, working in a noisy café, or taking important calls. To block out the chaos, you need the right pair of earbuds or headphones. However, while searching online, two terms often create confusion: ANC and ENC.
In this guide, you will learn how both technologies work, their pros and cons, and how to choose the right noise-cancelling headphones for your needs.
What Is ANC? Its Benefits and Drawbacks
ANC means active noise cancellation, and it listens to your surroundings using a built-in microphone before generating anti-noise or inverse frequency that blocks out background noise before it reaches you. Using ANC while listening to a movie, music, or podcast lets you concentrate on the sound even in noisy places like a bus, an airplane, or a café, without needing to crank up the volume.
However, these headphones consume a lot of power and quickly drain the battery. Some users describe a feeling in their ears, as though their eardrums are being tugged. Additionally, ANC may reduce environmental awareness, posing a safety risk, especially when outdoors, for example, while running or cycling.

What Is ENC? Its Benefits and Drawbacks
To specifically target and separate your voice from background noise like traffic, wind, typing, etc., ENC, or environmental noise cancellation, relies on software algorithms and beamforming microphones. ENC ensures that the person listening to you can hear you clearly and hence is best when you are taking work calls or online meetings.
These headphones also consume less battery than ANC headphones. The only drawback of ENC headphones is that you don’t get a listening experience for yourself, as they don’t cancel the noise you hear. You will listen to everything in the background while listening to music or attending calls.

ANC vs ENC: A Quick Comparison
| Feature | ANC | ENC |
| Main purpose | Immersive listening | Clear calls |
| Focus | Incoming sound | Outgoing sound |
| Best for | Music, travel | Calls, meetings |
| Impact | You hear better | Others hear better |
When To Choose What
Choosing between ANC and ENC depends on why you are using the headphones. Since both technologies solve different problems, it would not be right to say one is better than the other. Here are some situations and which headphone will be best suited for you to make an informed decision:
| Situation | ANC or ENC |
| Commuting, flying, or traveling | ANC |
| Working or studying in a noisy environment | ANC |
| Listening to podcasts or music without distractions | ANC |
| Online meetings, work calls, or gaming with voice chat | ENC |
| Taking calls from a noisy cafe or street | ENC |
If you take more calls in a noisy space yet want immersive, quiet listening for the rest of the time, choose headphones that have both ANC and ENC, rather than just one. Even though ANC will improve the listening experience, the headphones will need more battery to run continuously, shortening their battery lifespan between charges.
If you want a more battery-focused headphone, consider this point as well while making your final decision.
What To Consider When Buying
If choosing ANC, basic ANC reduces noise levels by 20 to 25 dB. Up to 38dB can be produced by high-quality ANC, which is sufficient to turn a noisy coffee shop into a quiet library.
If selecting ENC, look for indications of more advanced processing, such as “dual-mic ENC,” “AI noise suppression,” or “CVC 8.0. The most reliable one is user reviews published regularly, which include call quality.
Conclusion
Choosing between ANC and ENC is a tricky decision because they both deliver excellent service performance in different situations. If you’re looking for noise-canceling headphones for your everyday commute, you can opt for ANC headphones. If you need headphones for work or gaming, however, then opt for ENC.
