Noise canceling headphones against isolation headphones. Which to buy.

Η πιο πρόσφατη μόδα στα ακουστικά είναι η θορύβου, αν και δεν είναι νέα τεχνολογία. Τα ακουστικά ακύρωσης θορύβου υπάρχουν εδώ και αρκετό καιρό. Ας δούμε τις διαφορές που έχουν με τα απλά ακουστικά απομόνωσης θορύβου και πως να διαλέξετε τι να αγοράσετε.


Two what you need to know when deciding to buy headphones, is “noise cancellation” and “noise isolation”. You may also see them as "active noise cancellation" and "passive noise cancellation", or in the English terms noise cancellation and noise isolation, respectively. The type of headphones you will need to buy will depend on how powerful and quality your ambient noise you need to cut while listening to music.

And no, it's not so simple to say that "one is better than the other". Each type has its own advantages. Check out this article to find out the differences between noise cancellation and noise isolation and which ones you really need.

How does noise isolation work?
Sound isolation is the simplest of the two noise reduction methods. The purpose here is to isolate your ears from as much environmental noise as possible, without using electricity.

Noise isolation is usually provided by two types of headphones: in-ear and over-ear. In-ear headphones, also known as headphones , συνδέονται απευθείας στο ακουστικό πόρο του αυτιού σας και τον σφραγίζουν πλήρως. Τα ακουστικά πάνω από το αυτί χρησιμοποιούν αφρώδες υλικό, υψηλής πυκνότητας, για να καλύψουν ολόκληρο το αυτί σας από όλες τις πλευρές. Αυτού του είδους τα ακουστικά σε ορισμένους χρήστες προκαλούν κοκκίνισμα και ιδρώτα στα αυτιά, ιδιαίτερα αν τα υλικά s is of low quality.

The more complete the ear seal is, the better the isolation of the noise. It's simple, really, but the important thing in this method is the quality of sealing. The materials used, the ability to isolate the outside air that transmits noises and the overall adjustment of the headphones to your ears are important elements. These factors are what distinguish the poor headphones that isolate the noise from those that really work impeccably.

How does noise cancellation work?
The noise cancellation is a bit more complicated than the noise isolation. While noise canceling headphones may well be using noise-canceling headphones, they focus more on intelligent, active technology on the handset itself.

The noise canceling headphones have three additional elements: a tiny microphone, a digital signal processor (DSP) and a battery.

The microphone is listening to them of the environment. These sound waves are analyzed by the DSP, which then produces opposing sound waves. The speakers in the headphones, along with the music, also play these opposing sound waves, which clash with the ambient sounds and cancel each other out. And, of course, the battery supplies electrical power to all these circuits.

The whole process happens so quickly that you can not understand that it really is. However, it is not so fast that it can handle any sound. This is why noise canceling works best against consistent noise, such as hum in an airplane or people who speak with constant intensity. New and sudden sounds, such as the blow of a knocking door, can be heard as the system prevents them from canceling them.

Headphones with Lightning and USB type C
Smartphones have a new answer to noise canceling headphones. Recently, the iPhone 7 removed the classic stereo jack and some Android phones opted for the USB Type-C jack instead of the 3,5 millimeter round hole. This means that a new line of noise canceling headphones is coming to market.

The need for a DSP and a battery made it difficult for headphones to have noise canceling. But as the headphones can now be plugged into the phone's charging jack, they can draw power from the phone itself (and no longer has the internal battery). They also have access to the internal DSP of the phone, which can process the sound waves and produce waves of cancellation.

Example Libratone Noise Canceling Headphones with Lightning Plug, which cost 159 pounds from Amazon, benefit from these features. As manufacturers are removed from the 3,5 socket, we should see more and more such devices.

But what kind is best for you?
Now that you know the difference between the two types of external noise reduction, you need to see which of the two is the best for you. It's not a simple answer. Both have their own pros and cons.

Levels of Noise Reduction
In general, noise cancellation is more effective than noise isolation. This is simply because the noise canceling headphones usually use both cancellation and isolation, so you have twice the efficiency of noise reduction.

However, low-cost noise canceling headphones lack the thick foam required for good isolation and instead rely more on active technology. This means there are more ambient noise inputs to your ears. Because of this, high-quality noise-isolating headphones are often much better than low-quality noise-canceling ones.

Sound quality
This depends entirely on how much you love the fidelity of sound. In noise canceling headphones, built-in DSP and extra sound waves can affect the sound quality. While you do not have a problem if you are willing to pay a reward for high quality noise canceling headphones, when you lower your budget then the quality goes down and then the difference is definitely noticeable.

In noise-isolating headphones, no extra waves are created, so the it is truer to the original sounds. Sound engineers prefer sound-isolating headphones, since sound is what needs to be heard.

Noise canceling will not work if the battery is over and this means it is another gadget that you should charge regularly. You probably have already used and mechanically charged the process of charging various electronic trinkets (mobile, power bank, wireless keyboard, mouse, cordless headphones etc.), but it is something that you have to consider.

But remember that high quality noise canceling headphones also include strong isolation, so even when the battery is dead, you can continue listening with good audio fidelity.

Given the additional technology required, it is no surprise that noise canceling headphones cost more than equivalents that have only noise isolation. It's one of the most expensive headphones but it's worth it.

For example, the price of Audio-Technica ATH-W5000 can you trouble !!!!

What should you buy?
Basically, everything is relevant. It has to do with the faithfulness of the sound you are looking for and your wallet. And you should also read the above analysis to find out which headphones are right for you. What you really need and not what's the best model.

In the first place, decide whether you prefer ear lice (in the ear), just headphones or headphones that cover the entire ear.

Second, decide your budget. You need to know how much you are willing to pay.

Thirdly, figure out which device to connect to. If it is your new single-port iPhone X, then it may be sensible to make the purchase of best bluetooth headphones.

Fourth, where will you use them? If the noise you want to cut is fixed (like airplanes or trains) then cancellation is useful. If you're going to run with them in parks and roads, maybe noise isolation is not a good idea, since you will not hear car traffic or other major sounds. Think again.
