If you are looking for a new pair of headphones for your cellphone, computer or MP3 player, it is obvious that you want to choose a good pair with the best sound possible. To make a smart choice, most of the times one gets carried away by appearances or advertising and that in fact does not influence anything in addition there is a great variety of styles of headphones and brands … Well, this post has the intention to help you choose good. Below we offer you a complete guide so you do not miss any details when choosing the Best Headphones.
There are different types of mobile headsets that are distinguished by their mode of insertion to the ear and according to this, they adapt to different needs .:
The most common classic headphones, which come in almost 100% of the products you buy. These go above the ear canal and respond very well at high frequencies. They are the most economical, and present an acceptable quality of audio and have low isolation from the outside sound, so you can be aware of what is happening around you. They are suitable for going on the street or in public transport. Personally I do not like them and In my case they are uncomfortable
In-Ears or Intraaural (In-Ear Headphones)
They are the best quality of the type of compact earphones, are introduced into the ear ,. In this way, they hold the ear very well, in addition to having an advantage of canceling the noise passively (reduces noise due to materials and positioning) provide us the deepest bass. Due to having this great insulation, it is recommended to use them for long trips or in environments where your attention is not needed. If you walk in the street with them, you should use only one to be aware of the outside. They are highly recommended for people traveling in microbus or for walking on the street, and for sportsmen. Personally they are my favorites !, they are very comfortable and they listen well they are not of a great size
Highly used as headphones for DJs and computer headsets. Nowadays they are fashionable to be so visible they do not normally contain a cap as big as the Headphones and they put almost on covering the ear. Its main defect is that the sound is not completely isolated but, they present an excellent quality of audio and isolation. In hot weather, they are also often uncomfortable, as they heat up the auditory area.
They come in various shapes and sizes, Their noise cancellation level is medium and can be used for both professional and personal use. They are very comfortable, because they cover all the ear, and they are fastened of the head, thus they are not falling to you. Your audio is excellent (if you choose!). They have an active noise cancelation.
And have a high level of comfort in the ear, although they are somewhat uncomfortable as they warm the hearing area. These types of hearing aids are recommended for spaces where you do not have as much physical activity or require too much attention because of their great isolation from outside noise.
Well, we have already seen the various types of headphones available in the market, Now, also in addition to considering the types, you must consider the quality of the hearing aids. These are 4:
- Spectrum of Frequencies
The impedance is the resistance to the passage of electric current. It is measured in Ohms (Ω) – (Ohms), while less impedance, better volume (eye, more volume does not always mean better quality). Also impedance is like the current expenditure you need to function properly. Note that there are headsets that ask for 300Ω like the Senheiser HD 800. Those you can not connect them to an iPod or a conventional computer, since they would listen very low and require if the hearing aids need more power than our equipment can give, we will not be able to enjoy them Completely or we will have to buy some portable amplifier. For an MP3 they must have very little impedance (10O or less) to work hard and well. While lower range of Ohms cover the headset, better!
Spectrum of Frequencies
It is one of the most important characteristics when choosing. Basically, it consists of the range of sounds that we will be able to hear with the headphones. It is measured in Hertz (Hz). The sounds that a human is supposed to hear range from 20 Hz to 20 kHz (20000 Hz), but in general we do not hear exactly that, but almost all headphones have from 20 Hz to 20 kHz, or an approximate.
From 20 to 260 Hz are the SERIOUS sounds
From 260 to 2000 Hz are the MEDIA
From 2000 to 20000 Hz are the ACUTE
Any tone below 20 Hz is an infrasound, so we will not hear it, just like any tone higher than 20000 Hz, which is an ultrasound. The greater the range in Hertz (Hz) but the dynamic bone the first number is the lowest possible frequency. The lower the number, the better.
The second number is the highest frequency the hearing aids can reach. The higher the number, the better.
It is measured in decibels (dB), and is basically the maximum volume that the headset can output. The vast majority reaches 100 dB. The higher the decibels, the more “high” or “stronger” you hear. This number is important because at 100 dB hearing aids can slowly damage your ears and bring you serious problems in posterity. The maximum limit that frequently rules are 100 dB. The 0 dB is the theoretical silence. It is worth mentioning that decibels are a logarithmic measure.
To give you an idea of the volumes: A normal conversation goes from 60 to 70 dB. The sound of a crowded restaurant is 85 dB. The barking of a dog can reach 100 dB. One chainsaw, 110 dB. The sound of an airplane taking off goes for a tremendous 140 dB that would leave you without ears. As a rule, as of 125 dB, pain is beginning to be felt. Decibels (dB) is basically the maximum volume. The higher the decibels, the more “high” or the “stronger” you hear. Should not exceed 1oo dB
There are 2 types: Active and Passive. The passive is the one we saw in the types of Inner Ear Earphones, which based on materials reduces noise (Sponges, Gums, Pressure on the ear, etc.). And the Activa, which also influences the price of the phones and needs extra energy, has its main feature, eliminate in almost 99% the outside noise, that is, you will hear the music without hindrance, and the best, at a low volume.
