Part 4: Active headphones or Passive Headsets?What would be the difference?

That’s one of our most commonly asked questions, we get it all of the time and, frankly, we are sick of sending the same stock reply over and over again. So, we decided to solve it once and for all.

Now, before we go to any extent further, I’m off to draft the stock email that directs someone to this article, back in any minute…….You’re still there? Good. I stopped off to buy a vitamin drink and a cup of tea too, sorry.

OK. To put it plainly, there are two varieties of noise reduction, active and passive.

Passive noise cancellation/reduction is often a by-product of wearing the headsets in the first place. If a headphone covers your ears up, it fundamentally has a similar noise cancellation effect as a set of earmuffs. The sound has to work that much more difficult to travel to your ear if it must initially pass through a hard surface. Passive noise reduction comes mainly from blocking, or covering your ears and playing a louder sound in closer proximity. If the friend is trying to talk to you and you can’t pay attention to them due to the headphones, then that is passive noise reduction.

Active noise cancellation/reduction is a little more scientific. Earphones that actively cancel outer noise do so by producing a low field of white noise around your ear, this effectively masks outside sound and is a function in and of itself, away from the sound reproduction performance of those speakers.

Being truthful, anything you put in or around your ear features a passive noise cancellation effect, but only headphones pre-loaded with noise cancelling functions will create a masking white noise. This noise won’t interfere with the working of the headphones, but it’ll cover the sound from wind, rain, road works and the other train passengers and their noisy mobile conversations.

Noise cancellation/reduction earphones will do a much better job of drowning out the sound pollution generated by barking dogs, train bulletins, bad street buskers and those charity trolls who stop you in the street.

Joking aside, this is the FAQ because it is a very good one to pose. Noise cancellation functions considerably add to the cost of your headsets and it is completely worth knowing what you’re purchasing before you lay your hard earned down onto the counter.
