In a further step towards the direction of a world free of cables, modern models of existing headsets on the market today provide us with an experience and ease of use that cannot be compared in any way to the old method.
Be tied to the sound source via a cable, it is not exactly a pleasant way to listen to music, especially considering the ease that now offer stereos with all your lists functions to be used by remote control.
Moreover, basically, the wireless headset market is dominated by three sound transmission systems: RF (Radiofrequency), IR (Infrared) and Bluetooth.
In the case that we are about to purchase a pair of wireless headphones, it is wise to know some useful tips to make buying intelligently. In this way we can invest the money wisely, buying a product that really suits our needs as a user.
While buying headphones, we must consider a number of parameters to decide which of the three transmission systems is best for us.
Is very important to keep in mind that not all headphones are designed for the same purpose. In the market we can find a wide variety of models covering most user expectations.
Usually in audio or computer stores, we can find models of wireless headsets for indoors, which can be easily recognized thanks to its size and weight, but also are very extended the headphones for MP3 players, mobile phones or computers, lighter, suitable for easy transport and use.
Notably, most of these models incorporate noise cancellation technology to avoid any interference from electrical or similar machinery.
The range, signal coverage and sound quality are determining factors in buying. Consider that if you acquire a certain type of system with the required parameters to be used in a small environment, this equipment will not serve us in larger spaces, and vice versa.
It is also very important to remember that each of the systems used by manufacturers has advantages and disadvantages depending on the type of use in which we will use.
In this sense, the RF, or Radio Frequency, as also it called, offers an excellent coverage distance of almost 100 meters, and a radius of listening to 360 degrees, making it ideal for use in large areas and abroad, the truth is that it susceptible to interference.
In the case of systems IR or infrared are a good choice for when we are tied to a fixed device, as its range is limited by a line of sight, i.e. the components that make up the system must “see” among them for to reach its maximum gain and fidelity.
As for Bluetooth, it stands out as a technology that is incorporated virtually all modern devices, and manufacturers take advantage of this presence to work with audio, but Bluetooth is not distinguished by their audio quality or its scope, and that is why there are some attempts to try to produce a combination of both with the objective of achieving better range and fidelity in the market.
Another point very important to evaluate when buying wireless headphones, is the aspect of autonomy they offer. In this point we have to figure out the time it takes to charge the battery once discharged, some models can reach up to 16 hours. It is also important to know the period of full autonomy before discharge.
Another important consideration to take into account is the ease of use of headphones and weight, and also that it provides some broad helmets to completely cover the ear, an aspect that directly affects their sound quality and mainly in low frequencies.
