Headphones are very important for any PC user, especially if in the room other than him there are other people doing their own things. Only this way it will be possible to play games or watch movies without disturbing anyone. One thing remains - to choose suitable headphones.
Here's an interesting article on how to choose them correctly and what you really need to pay attention to. But first you need to learn - the headphones can be either premium-class, or budget. But it does not say that inexpensive models are necessarily worse than expensive ones.
When choosing headphones, decide on the type. Closed models are good if you spend no more than 3 to 4 hours in them, otherwise get ready for hearing problems. Otherwise, take the open, so you do not have to swallow tablets every night from a headache and suffer from other disorders.
Do you sit at the computer and very seldom have to leave it? Take wired models. Do you often have to leave your workplace? Then you should think about buying a wireless headset, but in this case always keep a few charged batteries handy.
The frequency of sound plays a role only in one case - you are a music lover, unable to live without your favorite tracks. In this case, this indicator does play an important role, in the case of an average user, there will be enough headphones to output sound at a frequency of 18,000 Hz or less.
Impedance (resistance), too, does not play a special role.
In the case of computer headphones "with a head" enough standard 30 Ohm. But you can take models with greater resistance, the sound will be cleaner, but it's important, again, for music lovers or those who are extremely critical about sound quality.
Weight - but this is very important. Do not forget that you will have to wear headphones on your head. Make sure that they are really comfortable sitting and you will not be hard. Otherwise, the ears and neck will get tired much faster.
