The Sony DR BT20NX are wireless headphones that allow unrestricted movement and thus increase comfort while listening to music. Because of this feature wireless headphones are especially popular with casual users. On the other hand, the limiting factor of wireless headphones is a certain delay in sound transmission between the source and the headphones (almost indistinguishable for the average user), and they also need to be charged regularly. Unlike wired headphones, where the headphones are charged by the connected cable itself, wireless ones must be charged separately. The maximum range of the headphones is up to 10 m. This range represents the distance from the sound source at which the headphones with wireless sound transmission can be used. However, the maximum range may be affected by obstacles such as walls or people, etc.
These headphones are in-ear type and are therefore designed to fit directly into the ear. This allows them complete or at least partial isolation from external noise. Such headphones may also have an ambient sound isolation function, which affects the degree of their isolation capabilities. Compared to over-the-head headphones, in-ear headphones are much more portable The weight of the headphones is 33 g.

The sound quality can be affected by many factors. For many users the frequency range is a key feature of headphones. The wider the range, the more detail and nuance you will hear while listening. However, every individual perceives frequencies differently, so the frequency range of headphones varies according to individual needs. The average person perceives frequencies in the range of 16 to 20,000 Hz, so headphones with a frequency range of 20 to 20,000 Hz are most commonly available. If you are looking for headphones with a good bass performance, you should aim for lower range values (bass represents frequencies up to about 256 Hz), while high range values (frequencies roughly above 2,048 Hz) will be better for reproducing high tones. The frequency range of headphones Sony DR BT20NX is 20 - 20000 Hz.
Headphones consist of many important parts, including the diaphragm, which is responsible for converting electrical signals into sound. The diaphragm, with a thickness of around 6 mm, is very sensitive to changes in high frequencies but less sensitive to bass. For a relatively balanced sound profile, a medium-thick diaphragm of around 10 mm is used, which can reproduce both bass and treble. A diaphragm with a thickness of around 20 mm is not as quick to respond to changes in the audio signal, and this results in poorer bass listening. However, it is very sensitive to higher frequencies. In the case of this model, the diaphragm is the PET.
