Evaluation criteria
Before buying a pair of earbuds for your PC, it is also good to consider the following
technical characteristics that allow you to identify each model's advantages and
disadvantages. Here's what you need to know on a technical level before making a good
purchase:
The frequency response is the value that indicates the range of frequencies that
the earbuds can cover, and is expressed in Hz. The human ear can perceive a range
of frequencies ranging from 20 Hz to 20,000 Hz, so most earbuds try to stick to
this range,
Impedance is the value that indicates the resistance exerted by the earbuds on the
audio signal and is expressed in volts/ampere (ohms). The higher the impedance,
the better the sound quality. For optimal listening, the earbuds and the PC should
have the same degree of impedance,
Sensitivity is the acoustic pressure expressed by the earbuds about the applied
voltage. In short, the higher this value, the greater the volume guaranteed by the
integrated speakers. The sensitivity value is expressed in decibels (dB).
The advantages of wireless
Why choose a wireless headset to use with your PC? Wireless earbuds are the increasingly
sought after model of earbuds, and in recent years they have had a real increase in sales.
Wireless earbuds, whether earphones or with a headband, are very comfortable and offer
excellent mobility, both at home and outdoors, especially for those who play sports or
those who use their smartphones to listen to music.
They can use different connection systems: wireless, Bluetooth, radiofrequency, or
infrared. The most popular are the Bluetooth ones that can be quickly interfaced with
other devices and have a coverage of about 10 meters.
For the PC (but also for listening to the TV at home), radio frequency (RF) earbuds are
the most commonly used because they offer a more excellent range of action, even up to
100 meters, leaving the person free to roam around the house without losing the signal.
The wireless earbuds are rechargeable and offer an excellent autonomy that can be up to
10-15 hours, depending on the model.
Microphone and controls
Most wireless earbuds have a microphone to talk to friends, and commands that allow
you to control multimedia playback and adjust the listening volume. The commands are
almost always universal, in the sense that they work the same way, regardless of the device
to which the earbuds are connected. Still, there are exceptional cases in which the
