A PNR (Passive Noise Reduction) aviation headset is a type of headset specifically designed for pilots and aviation professionals who require effective noise reduction during flights. PNR headsets utilize passive noise reduction techniques to minimize the impact of external noise on the user's hearing. With a specialized earcup for noise-proof insulation, it's worked by mechanically blocking sound waves from entering the ear. With NNR of 23dB, it's a perfect choice for aviators.

What Is The Difference Between PNR And ANR Headset?

The terms PNR and ANR refer to two different types of headsets commonly used in aviation and other noise-intensive environments. Here's a breakdown of their differences:

PNR (Passive Noise Reduction) Headset: 

PNR headsets are equipped with passive noise reduction technology. They use physical materials and design features to block out external noise. The primary components of PNR headsets are ear cups with sound-absorbing foam padding and a tight seal around the ears. The foam absorbs and dampens the ambient noise, reducing its impact on the user's ears.

Pros of PNR headsets:

  • Affordability: PNR headsets are more budget-friendly than ANR headsets.

  • Durability: PNR headsets are known for their sturdy construction and ability to withstand wear and tear.

  • Reliability: PNR headsets do not rely on batteries or electronics, making them less prone to power-related issues.

  • Lower power consumption: PNR headsets don't require power, making them suitable for situations with limited power sources.

Cons of PNR headsets:

  • They do not eliminate noise completely, as some sound can still leak in.

  • They are less effective in reducing low-frequency noise.

  • May cause ear discomfort during extended use due to the tight seal.

  • Relatively simple and less expensive compared to ANR headsets.

  • No reliance on electronics or batteries, making them more reliable.

  • Provide a consistent level of noise reduction across different frequencies.

ANR (Active Noise Reduction) Headset: 

ANR headsets utilize active noise cancellation technology. They incorporate microphones on the outside of the ear cups that detect ambient noise. The headset then generates an "anti-noise" signal that is precisely out of phase with the detected noise. When the anti-noise signal combines with the ambient noise, they cancel each other out, resulting in reduced noise levels reaching the user's ears.

Pros of ANR headsets:

  • Effective noise cancellation: ANR headsets use active technology to cancel out external noise, providing a quieter listening experience.

  • Enhanced comfort: ANR headsets are designed with ergonomic features and cushioning for a more comfortable fit during extended use.

  • Customizable noise cancellation: ANR headsets often offer adjustable noise cancellation levels, allowing users to control the amount of noise reduction based on their preference and the surrounding environment.

  • Improved audio clarity: By reducing background noise, ANR headsets enhance the clarity and intelligibility of audio communication and entertainment.

Cons of ANR headsets:

  • ANR headsets are generally more expensive due to the added technology.

  • They require batteries or power source to operate the active noise cancellation circuitry.

  • Some ANR headsets may introduce slight audio artifacts or a faint "hissing" sound due to the cancellation process.

  • Highly effective in reducing both low-frequency and high-frequency noise.

  • Offer superior noise reduction compared to PNR headsets.

  • Provide a more comfortable listening experience as they don't rely solely on physical pressure around the ears.


In summary, PNR headsets use passive methods like foam padding and a tight seal to reduce noise, while ANR headsets employ active noise cancellation technology to actively counteract ambient noise. ANR headsets generally offer higher noise reduction capabilities, but they come at a higher cost and rely on batteries or power. The choice between PNR and ANR headsets depends on personal preference, budget, and the specific noise environment in which they will be used.

Key Features of PNR Headsets

PNR (Passive Noise Reduction) headsets offer several key features that contribute to their effectiveness in reducing external noise. Here are some of the important features you can expect to find in a PNR headset:

  1. Ear Cups: PNR headsets typically have large ear cups that encompass the ears entirely. The ear cups are designed to provide a secure fit and create a seal around the ears, preventing external noise from entering.

  2. Sound-Absorbing Padding: The ear cups of PNR headsets are lined with sound-absorbing padding or foam. This padding helps absorb and dampen ambient noise, reducing its impact on the user's ears.

  3. Sealing: PNR headsets employ a sealing mechanism to enhance noise reduction. The ear cups are designed to fit snugly around the ears, effectively blocking out external sounds and creating a quieter listening environment.

  4. Adjustable Headband: PNR headsets typically feature an adjustable headband that allows users to customize the fit according to their head size and comfort preferences. The headband ensures a secure and comfortable fit during extended use.

  5. Boom Microphone: Many PNR headsets come with a boom microphone attached to one of the ear cups. The boom microphone allows for clear voice transmission and communication with air traffic control or other personnel.

  6. Volume Control: PNR headsets often have built-in volume control options. These controls enable users to adjust the audio output to their desired level, ensuring clear communication and comfortable listening.

  7. Durability: PNR headsets are designed to withstand the demanding conditions of aviation environments. They are typically constructed using durable materials that can withstand frequent use, rough handling, and exposure to various elements.

  8. Weight and Comfort: PNR headsets aim to provide a balance between noise reduction and comfort. They are designed to be lightweight and ergonomic, minimizing discomfort during prolonged use.

  9. Compatibility: PNR headsets are compatible with standard aviation audio systems and intercom systems commonly used in aircraft.

It's important to note that the specific features and design may vary among different models and brands of PNR headsets. It's recommended to review the specifications and features of a particular headset before making a purchase to ensure it meets your specific needs and preferences.
