Adaptive Noise Cancelling Headphone Kit with ESP32
Silence the World: Build Adaptive Noise Cancelling Headphones with ESP32
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine wearing headphones that intelligently mute the drone of a fan, traffic hum, or lab chatter — all without a commercial ANC chip. This kit guides you to implement feedforward adaptive noise cancellation using dual INMP441 MEMS microphones and an ESP32's processing power. By the end, you'll wear a fully functional noise-cancelling headset and understand the core algorithms behind modern audio gear.
What You'll Build
You'll build a pair of over-ear headphones equipped with active noise cancellation. Two tiny digital mics capture external noise; the ESP32 calculates the inverted waveform in real time and feeds it into the audio path through a DAC and amplifier, canceling low-frequency rumbles before they reach your ears. The final result is a standalone, battery-powered ANC headphone with a 3.5mm input for your music source.
What You'll Learn
- Implementing I2S communication between INMP441 microphones and ESP32
- Real-time adaptive filtering and phase inversion on an embedded microcontroller
- Interfacing multi-channel DACs (MCP4728) for precise audio signal generation
- Designing a power-efficient audio system with LiPo battery and charging circuit

Who This Kit Is For
It's purpose-built for third-year and final-year B.Tech students in ECE, EEE, or CS tackling audio DSP as a major or mini project. Ideal for participants in Smart India Hackathon or Tinkerers' Lab initiatives at IITs, NITs, VIT, and BITS Pilani who need a working ANC prototype. Students with prior ESP32 and soldering experience will find the challenge right-sized.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Our AI companion guides you through every connection and code block. If you need a human, WhatsApp our support team for personalized help.
Do I need prior experience with DSP or the ESP32?
Familiarity with Arduino IDE and basic C++ is recommended, but our build companion explains the DSP principles and code step by step. You'll learn as you build.
Can I use these headphones with my phone or laptop?
Yes, the kit includes two 3.5mm TRS jacks: one for input from any standard audio source (phone, laptop, MP3 player), and the other for output if you want to bypass the built-in ear cups.
What kind of noise does this system cancel?
The feedforward ANC design is most effective against low-frequency continuous noise like engine hum, fan drone, or AC rumble. Sudden transient sounds are not cancelled.
Two INMP441 mics on ESP32 compute anti-phase signal and mix with audio to cancel ambient noise.
