The headset is an indispensable accessory for some users, whether to spend time in traffic or even to exercise.However, when buying a device, several questions may arise with the numerous specifications and features that the devices offer.
Enhancing the sound of the headset with the Dolby Surround function
To understand the operation of the headphones and decide which device is worth investing, check the list with the answer to some questions.Here’s how to interpret the impedance and power data and which connector to choose.Also find out if a cordless and noise canceling accessory is worth it.
1) Understanding the numbers
When searching for a headset the user finds several specifications that, for beginners, may only complicate the choice of the accessory.So when viewing the information of the model, remember that the impedance is directly linked to the music volume and the higher the impedance, the clearer and the better quality is sound.Good headphones, for example, have numbers above 25 Ω.
The power of the headset follows the same line of reasoning, and the higher it is, the louder the sound will be.In addition, the sensitivity, measured in decibels, indicates the volume that the handset can reach.It is understood that from 85 dB is already high enough to affect the hearing.
The loudspeaker, better known as speaker or driver, is directly linked to the quality of the handset.The larger it is, the better the impedance, power and sensitivity.

2) Plug copper, silver or gold?
More fragile and more common in cheaper headphones is the copper plug, which oxidizes easily and consequently loses the ability to function.The most expensive is the gold, which has a higher resistance because it is more malleable material, different from the copper and silver that are harder.By having a slower oxidation process, the golden connector guarantees a much longer durability to the handset, which directly reflects the price, being found in the more expensive models.
3) Is a headphone better than an in-ear earphone?
The quality of the headset depends little on the format and more of the specifications, ie a headphone may be better than an in-ear earphone in the same way that the headset can be better than a headphone.
For those looking for portability, the intra model is the most appropriate because it is more discreet and light.The model fits directly into the ear canal and, precisely because of this, is what most isolates external noises.
The so-called supra-auricular models, which cover the entire ear, are indicated for activities that do not require many movements.The accessories are usually padded and very comfortable, being preferred by those who value the sound quality and especially the bass.Proof of this is the model chosen by professionals such as DJs and music producers.
4) Wireless handset loses audio quality?
Wireless-enabled headsets work with three connection options, and each works differently on the accessory, interfering with or not in audio quality.
The Bluetooth connection, which is best suited for those seeking compatibility with the major devices on the market.Although it works with limited range, usually up to 10 meters, the models are less susceptible to interference that may affect the sound.
There is also the infrared connection, which in order to function must be in the same environment as the transmitter.Otherwise, there are failures in audio transmission, meaning there is not much portability.
Radiofrequency connection is most affected by interference from other devices, thus interfering directly with sound.
It is worth remembering that all wireless models need energy to work, and it is necessary to evaluate the operating time of each model.
5) Noise cancellation: is it worth it?
Some headphones are able to isolate any external sound, avoiding mixing what is heard in the accessory with what happens around.The blocking can be done by noise cancellation or sound insulation.
Noise canceling is when the handset itself picks up ambient sound through the microphone and emits a reverse wave frequency to override external sounds.Isolation is a physical barrier against ambient sound, which is usually the case with intra-earphones that fit directly into the ear canal.
Headphones that have noise cancellation, because it needs to pick up sound and emit new waves, requires power to activate the feature, either through rechargeable batteries or batteries, which makes it the most expensive option most of the time.
For those who want to muffle the sound environment, but do not want to invest in a more expensive model, choose headphones that fit directly into the ear canal.For those who want to completely isolate the sound and look for something more professional, choose the headphones with the function of noise cancellation.
