What is ENC technology? Decoding the noise cancellation feature on headphones.

When choosing Bluetooth headphones or gaming headsets, users often wonder about audio terms like ANC and ENC. A lack of understanding of the function of each technology can easily lead to the wrong choice, directly impacting the call or music listening experience. Let's explore what ENC is in this article from GearVN.

 

Key points

1. ENC (Environmental Noise Cancellation) technology uses microphones to filter out background noise, making your voice clearer to the listener.
2. ANC (Active Noise Cancellation) technology creates sound waves in opposite phase to cancel out noise, providing a quiet environment for the headphone wearer.
3. ENC clarifies your voice for others, while ANC helps you hear better by blocking out surrounding noise.
4. ENC is ideal for gamers and online meetings, while ANC is suitable for listening to music, traveling, or when high concentration is required.

 

1. What is ENC technology?

1.1. Definition of ENC technology

ENC (Environmental Noise Cancellation) is a technology that eliminates ambient noise by identifying and removing background noise around the speaker. This technology optimizes the clarity of the audio transmitted during calls.

ENC is an environmental noise filtering technology that helps to make your voice clearer during phone calls.

1.2. Operating mechanism of the intelligent noise filtering system

The operation of an ENC (Environmental Noise Cancelling) microphone is based on a combination of hardware recording and software signal processing:

1. Dual Microphone System: The main microphone is placed near the mouth to capture the voice frequency range, while the secondary microphone is pointed outwards to pick up all surrounding background noise.
2. DSP (Digital Signal Processor): Analyzes the signals from the two microphones, then uses signal processing algorithms to identify and eliminate ambient noise frequencies, retaining only the speaker's voice frequencies.

ENC separates speech and cancels out background noise, useful in voice calls.

 

2. Comparison table of differences between ENC and ANC technologies

Criteria	ENC technology	ANC technology
Main purpose	Filter out background noise and improve call quality.	Noise cancellation enhances the listening experience.
Beneficiaries	The listener on the other end of the line	The person is wearing headphones.
Scope of intervention	Processing audio input from the microphone.	Processing the sound emitted from the speaker to the ear.
Application environment	Online meetings, team calls, voice calls	Traveling by plane, train, or bus, in noisy environments.

 

3. Practical applications of ENC technology

3.1. Importance for gamers and streamers

The microphone quality on a gaming headset greatly impacts teamwork. When gaming in a computer lab, teammates often hear mouse clicks, keyboard typing, or the sound of your cooling fan.

ENC technology thoroughly solves this problem by identifying and filtering out mechanical background noise. Your voice during team calls in Esports games will become clearer, allowing for faster and more accurate information transmission.

ENC helps filter out noise, keeping your voice clear during team calls or streams.

3.2. Benefits for office workers and students

During online conferences, noise from cafes, fans, or other household sounds can easily cause distractions. Headphones equipped with ENC (Earth Noise Cancellation) help to smoothly process these background noises before transmitting them to your partners or instructors.

This not only helps maintain the continuity of the conversation but also demonstrates the speaker's professionalism. Users can confidently work or study in any environment without worrying about being disturbed by noise.

ENC helps filter out background noise during online meetings, keeping your voice clear.

 

4. Advice on choosing headphones with ENC or ANC based on your needs.

4.1. Headphones for communication and online meetings

ENC technology should be prioritized. If you focus on conversational skills, consider the following criteria:

1. Choose a gaming headset with a boom microphone (sound pickup lever) that directs the sound close to your mouth.
2. Choose TWS earbuds equipped with a powerful integrated omnidirectional microphone system and ENC.
3. Reference product lines from Logitech and Razer offer stable voice chat quality.

4.2. Headphones for entertainment and travel

For listening to music or frequent travel by plane, train, or car, headphones with ANC technology are a top priority. You should choose wireless over-ear or in-ear headphones that support active noise cancellation.

This feature will filter out engine noise and street noise, creating a quiet personal entertainment space. This helps protect your hearing because you don't need to turn up the volume too high to drown out external noise.

You should choose headphones with ANC for better music listening, quiet movement, and ear protection.

4.3. Premium headphones to meet all needs

If you have a generous budget, invest in gaming headsets with the best ENC technology currently available, along with built-in ANC. These are high-end audio devices that perfectly meet the needs of both listening and calling.

Reputable brands like Logitech, Razer, Corsair, ASUS ROG, etc., all have flagship models that combine both technologies. Investing in these products provides long-term value and a professional communication experience.

High-end headphones feature both ENC and ANC for the best listening and calling experience.

5. Frequently Asked Questions about ENC Technology

5.1. Does ENC technology reduce the sound quality for the user?

No. ENC technology only intervenes in and processes the audio signal received from the microphone before transmission. This feature operates completely independently and does not affect the quality of the audio output from the headphone's speaker.

5.2. Do current mobile devices support ENC technology?

Yes. Most modern smartphones and laptops have built-in ambient noise cancellation. This digital processing algorithm works through the device's built-in microphone system or through software integrated by the manufacturer.

ENC technology processes background noise to clean up the transmitted voice signal, while ANC blocks out noise to clean up the sound you hear. Depending on your needs for online meetings, team calls, or personal entertainment, choose the right headset.
