If you’ve been shopping for wireless earbuds recently, you’ve probably seen terms like ANC, ENC, and AI Noise Cancellation.
Many brands use these terms in their marketing, but what do they actually mean?
More importantly, which technology matters most when choosing earbuds for calls, online meetings, commuting, or everyday listening?
Let’s break down the differences.
What Is ANC?
ANC stands for Active Noise Cancellation.
Its primary purpose is to reduce the noise you hear around you.
ANC works by using microphones to detect surrounding sounds and generating an opposite sound wave to cancel unwanted noise before it reaches your ears.
Common noises ANC can reduce include:
- Airplane engine noise
- Air conditioning hum
- Train and MRT noise
- Office background sounds
- Traffic rumble
Best For
- Travelling
- Commuting
- Working in noisy environments
- Listening to music
Limitation
ANC helps you hear better.
It does not necessarily help other people hear you better during calls.
What Is ENC?
ENC stands for Environmental Noise Cancellation.
Unlike ANC, ENC focuses on improving your microphone performance during calls.
ENC attempts to reduce surrounding noise so the person on the other end of the call can hear your voice more clearly.
Typical sounds ENC tries to reduce include:
- Crowd noise
- Traffic noise
- Office conversations
- Cafe background sounds
Best For
- Phone calls
- Video meetings
- Voice recordings
Limitation
Traditional ENC systems often struggle in extremely noisy environments and may make voices sound robotic or unnatural.
What Is AI Noise Cancellation?
AI Noise Cancellation is the latest generation of noise processing technology.
Instead of relying solely on predefined rules, AI-powered systems analyse audio in real time and learn to distinguish human speech from environmental sounds.
Modern AI systems can identify:
- Human voices
- Wind noise
- Vehicle sounds
- Keyboard typing
- Crowd chatter
- Background music
The result is significantly improved voice clarity compared to traditional ENC systems.
Best For
- Business calls
- Remote work
- Online meetings
- Public transport
- Outdoor environments
Limitation
Performance depends heavily on the quality of the AI processor and microphone system used by the manufacturer.
ANC vs ENC vs AI Noise Cancellation
While the scores above are illustrative rather than laboratory measurements, they reflect how these technologies are typically used.
| Technology | Main Purpose | Best For |
|---|---|---|
| ANC | Improve what you hear | Music, travel, commuting |
| ENC | Improve what others hear | Calls and meetings |
| AI Noise Cancellation | Intelligent voice enhancement | Calls, meetings, noisy environments |
Why AI Noise Cancellation Is Becoming More Important
The way we communicate has changed.
Today many people spend hours every week on:
- Zoom
- Microsoft Teams
- Google Meet
- WhatsApp Calls
- Telegram Calls
- Video conferencing
As remote work and hybrid work become more common, voice clarity is becoming just as important as sound quality.
This is why many premium earbuds now combine ANC, ENC, and AI-powered processing together.
How Soundcore Anker Liberty 5 Pro Uses AI Noise Cancellation
One of the best examples of next-generation AI call technology is the Soundcore Anker Liberty 5 Pro.
The Liberty 5 Pro combines:
- Eight microphones
- A 10-sensor voice detection system
- Bone-conduction sensing
- ANKER Thus™ AI Chip
- Advanced voice isolation algorithms
These technologies work together to identify your voice and suppress surrounding noise in real time.
The result is call quality that earned the Liberty 5 Pro a Guinness World Record certification for achieving the highest speech quality score (G-MOS) among true wireless earbuds.

Final Thoughts
ANC, ENC, and AI Noise Cancellation are not competitors. They serve different purposes.
ANC improves what you hear.
ENC improves what others hear.
AI Noise Cancellation takes communication to the next level by intelligently separating voices from surrounding noise in real time.
