Hi and welcome to the modern group of responses to the Earpiece inquiries. Ever desired to know about something headphone, earphone or headset related? Now is your opportunity. Due to a great deal of questions we are so regularly asked, we have reached into our mailbag and chosen the nine most significant (and most often submitted) questions. Enjoy.
Oh, by the way, if your inquiry isn’t here, then merely mail us an email and come back in a few… you might see it featured in the later series. Thanks.

That is one of our most commonly asked questions, we get it all of the time and, frankly, weíre sick of sending the exact same standard email over and over again. So, we chose to resolve it once and for all.

Now, before we go any further, Iím off to draft the standard email that directs someone to this post, back in a minute…


…You still there? Good. I stopped off to buy a vitamin drink plus a cup of tea as well, sorry.

OK. To say it plainly, there are two types of noise reduction, active and passive.

Passive noise cancellation/reduction is generally a by-product of wearing the headphone in the first place. If a headset covers your ears up, it fundamentally has the identical noise cancellation effect as a set of earmuffs. The sound has to work that much more difficult to travel to your ear how it must firstly pass through a hard surface. Passive noise cancellation arrives mainly from blocking, or covering your ears and listening to a louder sound in closer proximity. In case your friend is trying to speak with you and you canít hear them due to the headphones, then that is passive noise cancellation.

Active noise cancellation/reduction is a little more mechanical. Headsets that actively cancel outer noise achieve this by producing a low field of white sound around your ear, this actually masks outside sound and is a meaning in and of itself, from the sound replica performance of the speakers.

Being honest, anything you put in or around your ear has a passive noise reduction effect, but only headsets equipped with noise cancelling functions will generate a masking white sound. This noise wonít interfere with the working of the headphones, but it’ll cover the sound from wind, rain, road works and other train passengers and their noisy smart phone conversations.

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

Joking aside, it’s much a FAQ because it’s a good one to pose. Noise reduction features considerably help to increase the price of the headphones and it’s completely worth knowing what you’re buying before you put down your hard earned down onto the counter.
