Are you tired of being distracted by the constant din of background noise while trying to focus on your music, podcast, or video conference call? Do you wish you could immerse yourself in a world of pure, unadulterated sound, free from the distractions of the outside world? If so, you’re in luck! With the right kind of headphones, you can block out background noise and tune in to the audio that matters most.
Active Noise Cancellation: The Holy Grail of Noise Reduction
When it comes to blocking out background noise, active noise cancellation (ANC) is the gold standard. ANC technology uses a combination of microphones, amplifiers, and speakers to actively eliminate unwanted sounds. Here’s how it works:
- The microphone in your headphones picks up ambient noise around you, such as the hum of the air conditioner, the chatter of passersby, or the rumble of the subway.
- The microphone sends the sound signals to an amplifier and a processing unit in the headphones.
- The processing unit analyzes the sound waves and generates an “anti-noise” signal, which is the exact opposite of the ambient noise.
- The anti-noise signal is then played through the headphones’ drivers, effectively cancelling out the background noise.
ANC is incredibly effective at blocking out constant, low-frequency sounds like engine rumble, air conditioning hum, and airplane noise. However, it’s not as effective against high-frequency sounds like conversation or keyboard clacking.
Passive Noise Isolation: The Alternative to ANC
Not all headphones with noise reduction capabilities rely on ANC. Some use passive noise isolation, which is a more straightforward approach. Passive noise isolation involves using materials and design features to physically block sound waves from entering the earcup.
- Materials like memory foam, rubber, and plastic are used to create a snug, comfortable fit around the ear, preventing sound from leaking in.
- Some headphones feature earcups that are specifically designed to fit closely around the ear, reducing the amount of sound that can enter.
- Others may use noise-isolating ear tips, which fit deep into the ear canal to block out external noise.
Passive noise isolation is often less effective than ANC, especially against low-frequency sounds. However, it can still be very effective, especially in noisy environments like offices or public transportation.
Headphone Types: Which Ones Block Out Background Noise Best?
When it comes to blocking out background noise, not all headphones are created equal. Here are some of the most common types of headphones and their noise-reducing capabilities:
In-Ear Headphones: The Ultimate Noise-Blockers
In-ear headphones, also known as earbuds, are the most effective at blocking out background noise. This is because they fit deep into the ear canal, creating a tight seal that prevents sound from entering. In-ear headphones with noise-isolating ear tips can reduce ambient noise by up to 25 decibels.
Some popular in-ear headphones with excellent noise-reducing capabilities include:
- Bose QuietComfort Earbuds
- Sennheiser Momentum True Wireless
- Sony WF-1000XM4
Over-Ear Headphones: The Best of Both Worlds
Over-ear headphones, also known as circumaural headphones, completely enclose the ear with cushioning, blocking out ambient noise. They often combine passive noise isolation with ANC technology for maximum noise reduction.
Some popular over-ear headphones with excellent noise-reducing capabilities include:
- Bose QuietComfort 35 II
- Sony WH-1000XM4
- Beats Solo Pro
On-Ear Headphones: A Good Compromise
On-ear headphones, also known as supraural headphones, sit on top of the ear, rather than surrounding it. They often provide some degree of noise isolation, but may not be as effective as in-ear or over-ear headphones.
Some popular on-ear headphones with decent noise-reducing capabilities include:
- Grado SR60e
- Sennheiser HD 4.50 BT
- Beyerdynamic DT 240 Pro

Remember to consider the type of noise you want to block out, the level of noise reduction you need, and the additional features that matter most to you. With this guide, you’re one step closer to finding the perfect headphones that block out background noise and let you tune in to the audio that matters most.
What is Active Noise Cancellation?
Active noise cancellation is a technology used in headphones to actively eliminate unwanted ambient sounds. It works by using one or more microphones to capture ambient noise, and then producing a “negative” sound wave to cancel it out. This results in a quieter listening experience with less external distraction. Active noise cancellation is often used in combination with passive noise isolation to provide even better sound quality.
The effectiveness of active noise cancellation can vary depending on the type and quality of the headphones, as well as the environment in which they are used. In general, active noise cancellation is most effective against constant, low-frequency sounds like engine rumble or airplane noise, and less effective against high-frequency sounds like conversations or sharp noises.
What is the Difference Between Noise Isolation and Noise Cancellation?
Noise isolation and noise cancellation are two related but distinct concepts. Noise isolation refers to the physical blocking of sound through the use of materials or design features that prevent sound from entering the earcup. This can be achieved through the use of earcups that fit snugly around the ear, or through the use of materials like foam or rubber that absorb sound.
Noise cancellation, on the other hand, is the active elimination of sound through the use of electronic noise cancellation technology. This technology uses microphones to capture ambient noise, and then produces a “negative” sound wave to cancel it out. While noise isolation can be effective against certain types of noise, noise cancellation is often more effective against constant, low-frequency sounds.
How Do Noise-Cancelling Headphones Work?
Noise-cancelling headphones work by using one or more microphones to capture ambient noise, and then producing a “negative” sound wave to cancel it out. This is achieved through the use of electronic noise cancellation technology, which is built into the headphones. The microphones capture the ambient noise, and the electronics then produce an “anti-noise” signal that is the exact opposite of the ambient noise.
When the anti-noise signal is played through the headphones, it combines with the ambient noise to cancel it out. This results in a quieter listening experience with less external distraction. The effectiveness of noise-cancelling headphones can vary depending on the type and quality of the headphones, as well as the environment in which they are used.
