Technology Breakthrough｜Pengxinfa 9‑Mic Hybrid ANC, Redefine The Listening Experience Of High‑End Noise‑Canceling Headphones

With the rapid iteration of the wireless headphone market, Active Noise Cancellation (ANC) has become a core feature of high‑end headphones. However, many products still adopt a 6‑mic noise‑canceling solution. In complex real‑world scenarios, they suffer from insufficient noise reduction bandwidth, obvious wind noise, unstable noise‑canceling performance caused by loose wearing, and muffled sound quality after turning on ANC.

Shenzhen Pengxinfa Electronic independently develops the 9‑Mic Hybrid ANC Noise‑Canceling Technology. It breaks the technical limits of traditional multi‑mic noise cancellation. Equipped with a 9‑microphone array, feedforward plus feedback hybrid ANC architecture and self‑developed DSP noise‑canceling algorithm, it delivers a flagship noise‑canceling solution for over‑ear headphones covering full‑scenario use, wide frequency range, music playback and call performance. It is also our core selling technology for global markets.

What Is 9‑Mic Hybrid ANC Noise Cancellation?

Conventional ANC solutions are either pure feedforward or pure feedback: ‑ Feedforward microphones capture external ambient noise and perform well in suppressing low‑frequency rumble. ‑ Feedback microphones monitor residual noise inside the ear cup, correct noise‑canceling output and improve suppression on mid‑frequency human chatter.

Hybrid ANC enables the coordinated operation of both feedforward (FF) and feedback (FB) systems.

For Pengxinfa 9‑Mic Hybrid ANC, multiple groups of feedforward, feedback and ENC call microphones are arranged on each ear cup. A total of 9 microphones work together to build a 360‑degree stereo noise acquisition network. Multiple feedforward mics pick up external noise such as traffic, subway and air‑conditioner hum. Feedback mics monitor residual noise inside the ear cup in real time. Dedicated ENC call microphones capture human voices and filter ambient noise plus outdoor wind noise.

The DSP chip analyzes noise spectrum within milliseconds and outputs anti‑phase sound waves for noise offset. Different from mainstream 6‑mic solutions, the 9‑mic array provides more acoustic sampling channels. It achieves wider noise‑canceling frequency coverage and stronger environmental adaptability, balancing ANC depth and high‑definition ENC call performance. The maximum noise reduction depth reaches ‑40dB, delivering stable noise‑canceling effect for commuting, office and outdoor environments.

Four Core Advantages Of 9‑Mic Hybrid ANC Technology

1. Full‑Frequency Noise Cancellation, Stable Performance In Complex Environments

Common pain points of ordinary noise‑canceling headphones: poor suppression for low‑frequency rumble from subways and aircraft, limited reduction for mid‑frequency human voices in busy offices. Noise‑canceling performance drops sharply when the head cup shifts or wearing gets loose.

Pengxinfa 9‑mic array collects external and in‑cup sound via multi‑channel simultaneously. Feedforward mics block incoming noise while feedback closed‑loop system calibrates noise‑canceling output continuously. It effectively suppresses low‑frequency vibration noise from subways or planes as well as chatter in cafes and offices. No sharp degradation happens with minor wearing position changes.

2. Noise Cancellation Without Sacrificing Sound Quality, No Muffled Audio With ANC Turned On

A widespread industry issue: some noise‑canceling products over‑compress mid‑high frequencies by algorithm to pursue higher noise‑canceling parameters. Music loses high‑frequency details and sounds muffled once ANC is activated. It is hard to balance noise cancellation and sound fidelity.

Benefiting from fine‑grained noise sampling brought by 9 microphones, our self‑developed algorithm distinguishes ambient noise and music signals precisely. It only offsets unwanted noise and minimizes damage to original audio. High‑frequency details and dynamic layers of music are well preserved under ANC mode, realizing both noise reduction and Hi‑Fi listening experience.

3. Powerful ENC Call Noise Reduction, Crystal‑Clear Calls In Noisy Surroundings

The 9‑microphone array is designed not only for audio noise cancellation, but also for multi‑mic ENC call processing. Beam‑forming algorithm separates human voice from background interference to suppress wind noise and ambient disturbance when users make calls outdoors, on streets or in moving vehicles. Call recipients can receive clean voice, solving the common defect “great noise‑canceling for music yet poor call quality”.

4. Multiple Modes For Diverse Scenarios

Users can switch freely between deep noise cancellation, mild noise cancellation and transparency mode. Turn on deep Hybrid ANC for commuting to block outside disturbance; select mild ANC in offices to keep partial ambient sound; transparency mode lets users hear surrounding conversations without taking off headphones, safer for shopping and crossing roads.

Self‑Developed Core Strength, Audio Solutions For Global Partners

9‑Mic Hybrid ANC is Pengxinfa’s in‑house technology. Acoustic structural design, microphone array layout and noise‑canceling algorithm tuning are all completed internally. This technology is adopted in multiple over‑ear noise‑canceling headphone models including J28, J20S and J25.

Pengxinfa regularly attends Global Sources Hong Kong Electronics Fair, Hong Kong Autumn Electronics Fair, China Trade Fair In Dubai and other international exhibitions. We provide OEM / ODM customization services for worldwide clients. Based on 9‑Mic Hybrid ANC, we support custom development on hardware, algorithm and appearance to bring flagship‑grade noise‑canceling audio products to global consumers.

Closing Remarks

Competition for noise‑canceling headphones is no longer limited to nominal dB parameters. Real‑world comprehensive performance matters most. With hardware microphone array plus self‑developed algorithm innovation, Pengxinfa 9‑Mic Hybrid ANC breaks bottlenecks of traditional noise‑canceling technology and brings premium quiet listening experience to end‑users.

Moving forward, Pengxinfa will keep investing in audio R&D and continuously upgrade noise‑canceling, bluetooth and acoustic technologies, delivering more competitive audio hardware for global partners.
