Wireless headphones are relatively simple and important products, their main advantage - high mobility. They do not restrict the user's freedom of wire length. But the abundance of offerings makes it difficult to choose from, why decide how to choose a wireless headset can be difficult.
To ease of use of the equipment is maximized, it is necessary to determine the possible application conditions:
This will help determine the best working properties of equipment.
Radius of action
At home while working on a computer for watching TV or listening to music is not a great distance from the transmitter is required. Enough to provide freedom of movement to the minimum distance. And if you use headphones while household chores, then needed more freedom of movement around the apartment. This will require a reliable communication over large distances.
For this fit headphones with a range of up to 100 meters. It will be enough for a good signal in an apartment or small house. Radius reception Bluetooth significantly less. It will provide active movement without losing the connection within 10 meters. headphones with IR connection operable only by direct contact with the transmitter port.
acoustic requirements
Of particular interest to the audio quality typically exhibit music fans. But the general attitude to this indicator individually.
At radionaushnikov small ratio of the net signal to noise ratio. They are more susceptible to interference over long distances, especially if there are many broadcasting devices. On their background looks better analogues with Bluetooth and infrared port are immune to background noise.
In addition to protection from interference, acoustics evaluated for resistance and frequency range. Computer 32 is considered adequate resistance to ohms. For professional audio systems better suited impedance of 250 ohms. Best acoustical earphones must have a frequency range with a lower frequency close to 70-80 Hz.
The sound quality is also determined by the frequency response indicator (frequency response). It is usually placed on the packaging or on the product itself. Perfect sound corresponding to the image straight line.
transmission unit
Headphones without wires work equally well with all types of modern electronics, a Bluetooth or other types of remote connections. This is a different stationary television and audio transmission devices, personal computers or mobile equipment, including a laptop, tablet, player and so on.
Correctly identify the model of headphones can be required by the type of connection. Having Bluetooth and IR-port requires built compound of the same type of computer, smartphone or other device, and in their absence - of a suitable adapter.
Under hospitals can take inexpensive headphones with infrared connection. Smartphone is better to buy a Bluetooth headset.
Among other features, consider also the weight, ergonomics, battery type and capacity.
Overall options
Wireless headphones can weigh several tens of grams, or even half a kilo. Average weight - 200-300 grams. They are heavier than normal due to the batteries. With long-term use is better to think about choosing a gadget with optimal weight, which will be comfortable to wear all the time.
Ergonomics
Equipment to comfortably sit, shall be possible to adjust the size of the bow of the head, a soft shock absorber, convenient form of lip to the ears. This will reduce fatigue and improve the listening experience.
batteries
Here you can select a removable or built-in battery. Among the commonly used removable battery sizes AA or AAA. Integrated supply element must provide 8-12 hours of continuous operation, followed by charging.
Before buying always check customer reviews of popular models and consider their wishes, not to be mistaken with a choice.
