Noise Cancelling Headphones
Listening to music on public transport, in the street or at home can sometimes be complicated because of the surrounding noise. Whether it’s the discussions next to you, the work or the unbearable sound of the train, you do not always get the most out of your music. To better isolate you, more and more manufacturers of headphones offer models embodying active noise cancellation, in addition to passive isolation due to the pads of the helmet.
Noise cancellation, what is it?
On paper, the principle of phase cancellation used in the technology of these headsets is simple: against a disturbing external noise, earphones generate a noise that counteracts the disruption. Thus, persistent background noises such as that of a train or plane are annihilated. The noise reduction headphones are equipped with an ingenious system based on microphones that analyze the external noise. They then insert an opposite sound that cancels the first.
The main problem is on the one hand the relative efficiency of some, but especially the propensity to create another buzz that can be very unpleasant depending on the model.
Helmet supra or circum-aural
Two models of design compete in this comparison: supra-aural helmets and circum-aural. The former rest entirely on the ear and thus cover only the auditory flag. This is for example the case of Philips Fidelio NC1, AKG K 495 NC or Sony MDR-ZX750BN. The advantage of this type of helmet is obviously the size and compactness. Although smaller, they are easier to store and are also lighter. Disadvantage: their wearing can be painful after a few tens of minutes since they fully support the ear. Eyeglass wearers will have for their expenses, their ears being stuck on their branches. We knew more comfortable.
The second, circum-aurals, rest on the top of the skull and encompass the entire ear. They are therefore much more insulating. It is logically towards this type of helmets that the majority is oriented manufacturers in terms of noise cancellation, whether it is Bose, Sony or Beats. The ear is thus spared and only surrounded by the helmet. The downside, the helmet is necessarily bigger and cumbersome. Difficult for example to store in a jacket pocket, a bag will necessarily be necessary. Moreover, worn all day in an open space environment, for example, a heavy helmet with bad padding at the hoop can be embarrassing. This is also a point to observe when buying all types of headphones.
2 Best Noise Cancelling Headphones 2019
The the buyers trend guide editors have compared about 100 products and selected the best earmuffs.Lets see 2 among them.
1. Sony WH-1000XM3
If you are looking for a headset to isolate yourself from the outside world, the Sony WH-1000XM3 is an unbeatable choice. This latest revision of the Japanese manufacturer's flagship helmet offers a particularly effective active noise reduction, which immerses you in your music. The official application allows you to refine the rendering, choosing a profile that can identify station or airport announcements, for example, so you do not miss anything. To avoid spoiling, the audio quality is high.
2. Bose QuietComfort 20
When one thinks of noise-canceling helmets, one always imagines large arches and enveloping auricles, like a hard hat. In-ear customers will be delighted to learn that Bose is successfully venturing into this market through the QuietComfort 20. Comfort is ideal, with silicone earmolds matching the roof, and active noise reduction. We are not in an audiophile reproduction, but the rendering remains quite convincing, considering the great miniaturization. A solution to consider if you prefer a minimum footprint
Finally, this difference in design does not only affect comfort, but also the efficiency of the noise reduction system. A circum-aural headset will be much easier to isolate disturbing sounds. By its form, it already filters passively much better than a supra-aural model much less insulating by nature. That's why Sennheiser, which has been putting the package on noise canceling headphones for a few years, has opted for a circum-aural design on its HD 4.50BTNC.
