The era of
wireless headphones
is reaching its greatest point of exposure.
Today, the variety of Bluetooth (BT) models available accommodates all requirements in price and performance.
In this note, the best
for less than 5,000 pesos that are obtained in the country
and its main technical characteristics.
In this selection, the six headphones from
Sony, Philips, Klip Xtreme, BlackPoint and Primus
, are rated for hands-free talking on the phone, listening to podcasts and streaming music
,
while some models
they are
exclusive to sports or play online
.
One of the specifications that define
the condition of a headset is its drivers or internal speakers
, responsible for transmitting sound.
But also the autonomy it provides and the version of BT it uses to communicate with the mobile.
There are other secondary aspects such as portability, the materials in which its structure is affirmed and the design that it deploys, which must also be taken into account.
According to their level of isolation, there are headphones for outdoor or home use.

The cheapest are those that are placed in the ear canal - called in-ear or in-ear - and
start at less than 2,000 pesos
.
The supraural or diadem, which are supported on the ear,
are around 5,000 pesos
.
The circumaurals or HiFi, where the ear is covered by the padding, are obtained
from 8 thousand pesos
.

Technical aspects
The perception of sound, like the olfactory trace or taste,
are totally subjective impressions
.
Some may find something comfortable that for others is borderline tolerable.
To referee in this sensitive maze, technical specifications can serve as a quality stoplight.
However,
it is always advisable to try them before deciding
.
The key aspects, which are not always indicated at a glance by the manufacturer, are summarized in the following points.
The drivers are the emitters of the sound and their performance depends on
the acoustic clarity, the bass balance and the consumption of electrical energy
.
The in-ears come with drivers from 8 to 15 mm, while the supra-aurals range from 20 to 50 mm.
As a logical rule, the size will determine the maximum volume but not the quality.
Scope and autonomy
Being wireless,
these headphones depend on the autonomy provided by the battery.
However, its duration depends on the volume at which it is heard, whether noise cancellation is activated and the distance between the emitter and the receiver.
While the larger models
can provide up to 10 hours of music
, those that wear on the ear, can
not exceed 4 hours
, although through their case, they can extend their charge for another 4 hours.
The difference, both in cost and result, between two similar pieces of equipment is based
on the BT technology
that the device has adopted.
The condition for entering the TWS category is that the headphones are of the in-ear type (in-ear).
It is convenient that it is 5.0 onwards.
Since it achieves a greater range and transmission speed, together with energy efficiency.
The most suitable is Bluetooth 5.2. It
was conceived to improve audio quality and reduce energy consumption.
At the limit of what is justifiable is the frequency range.
It refers to how low or loud the headphones can ring
.
In this race the limit is imposed by the human ear,
which captures sounds between 20 and 20,000 hertz
(Hz).
The closer the range of the headphones to these values, the better they will hear.
Thus, those that fall between 80 to 19,000 Hz will be
able to reproduce the sound they receive with maximum fidelity
.
Those that are between 150 to 14,000 Hz will have disadvantages in the low tones, the sounds with low frequencies of the audible spectrum.
