Question 1

What Are The Disadvantages for Noise Cancelling Headphones?

Accepted Answer

There are some potential disadvantages of noise-cancelling headphones, that you should be aware of. For example:

Battery Drain: Active noise cancellation requires power to function, which can rapidly drain the battery life of wireless headphones. This means you may need to charge them more frequently.

Pressure Sensation: The way noise-cancelling headphones work, by generating opposing sound waves, can create an odd pressure-like feeling in some users' ears.

Sound Leakage: While noise-cancelling headphones are designed to block external sounds, they can sometimes leak audio, allowing others nearby to hear your music or calls.

Question 2

What is the difference between noise cancelling and active noise cancelling (ANC)

Accepted Answer

Basically nothing. Noise cancelling and active noise cancelling (ANC) are the same thing. They are just different terms used to describe the technology that actively reduces unwanted ambient sounds using microphones and sound wave opposition.

In simple terms, active noise cancellation is using microphones to pick up low-frequency ambient noise signals, and then generating an opposite sound wave to cancel out and minimize those noise signals before they reach your ears.

This is different from passive noise isolation, which just physically blocks out sound waves using insulating materials in the headphone design.

So while the terms "noise cancelling" and "active noise cancelling" are sometimes used interchangeably by different manufacturers, they both refer to this active noise reduction technology as opposed to just passive noise blocking capabilities.

Question 3

What is the difference between noise cancelling headphones and noise cancelling microphone?

Accepted Answer

The difference between noise cancelling headphones and a noise cancelling microphone is:

Noise cancelling headphones use active noise cancellation technology to reduce ambient noise reaching your ears when listening to audio through the headphones.

A noise cancelling microphone, on the other hand, uses noise cancellation to reduce ambient noise being picked up by the microphone itself when you are speaking or recording audio.

So noise cancelling headphones improve what you hear, while a noise cancelling microphone improves the clarity of your voice/audio recording by blocking out background noise from being captured by the mic.

Question 4

Are Over-Ear Headphones Better At Noise Cancelling?

Accepted Answer

Yes, over-ear headphones are generally better at noise cancelling than other types of headphones like on-ear or in-ear models.

The reason is that the larger ear cups on over-ear headphones are able to provide better physical noise isolation by fully enclosing and sealing around your ears. This helps block out more ambient sounds before any active noise cancellation technology is even applied.

Additionally, the increased space inside over-ear cup designs allows manufacturers to include higher quality noise cancelling microphones and circuitry more easily.

So with their physically noise-isolating fit combined with better noise cancelling hardware, over-ear headphone designs tend to outperform other styles when it comes to effectively eliminating unwanted external noises. Their larger size simply makes active noise cancellation more powerful.

Question 5

Will I hear external voices with noise cancelling headphones?

Accepted Answer

Yes, you will. With noise cancelling headphones, you may still hear very loud external voices, but most normal conversations and ambient noise will be significantly reduced or blocked out.

The noise cancellation technology in the headphones is designed to minimize lower frequency noises like engines, fans, etc. Very loud sounds or voices close to you may still be audible to some degree, though muffled and less intrusive than without noise cancelling.
