How to choose headphones

Sooner or later, each computer user, MP3 player or mobile phone thinks about purchasing good headphones. Quality models are durable and provide good sound while listening to music. The market presents many options that differ in both the type and price.

Decide with the type of headphones. They can be closed or open. Closed models (Beyerdynamic DT 770 Pro) have good sound insulation, so those surrounding do not hear music playback. In open-type headphones (Beyerdynamic DT 990 Pro) there are holes in the bowls, through which the sound gets out. There are also overhead and plug-in models (liners). The first (Sony MDR 1A) closes the ears, and the second (Creative EP 830) must be inserted. Inserts attract customers compactness and low cost, but overhead models are distinguished by the best sound quality. For athletes produce special models with our arc to secure them from falling during sports (Sony XBA S65).

Headphone connection type can be different. There are wired (Sennheiser MX 475) and wireless (SONY SBH20) models. Each of them has its advantages and disadvantages. Most of the models are wired, but they often constrain movement, unlike wireless versions that allow you to move freely. If you want to purchase wireless headphones, make sure the availability of automatic adjustment. Wireless type headphones have one minus - the battery that you have to constantly change. Therefore, its service life must be long enough.

The frequency range is very important, which affects the sound quality of headphones. The average value should be 18-20000 Hz (Philips SHC1300). To sound really high-quality, select a model with a diameter of a membrane from 30 mm (AKG K 702). Another important detail is harmonious distortion. They allow you to estimate the transfer accuracy with the input audio headphones. For high-quality sound, the harmonic distortion coefficient must be less than 1% (Sennheiser HD415).

The sound of sound in headphones is affected by sensitivity. Overhead models always provide good volume, but the liners can bring. Optimal sensitivity for such models should be at least 100 dB (Panasonic RP HT223GU S). Otherwise, the sound may be too quiet. Another important point is an indicator of headphones resistance. If it goes beyond the limits specified in the instructions for technology, it can simply fail. For portable equipment, models with resistance from 30 to 40 ohms are ideal (Audio-Technica ATH W5000).

If you are going to use headphones only at home, the option with a long cable is suitable. But on the street to walk with him uncomfortable. There are universal variants - cords whose length can be adjusted. They will be a good option for all cases (Sony MDR EX100IP).

Standard Type of Headphone Connector - Jack. It is divided into several diameters - 2.5 mm, 6.3 mm, 3.5 mm. The last two species are most common. In some headphones, the diameter of the connector is 3.5 mm, but in the kit there is an adapter by 6.3 mm (Audio-Technica ATH T200). It happens on the contrary.

If you are looking for a budget model, pay attention to such companies as Sony, Genius., Philips., Logitech, Panasonic, A4Tech.. More expensive options produce companies Grado., Sennheiser., Etymotic., Ultimate Ears., Beyerdynamic, KOSS., AKG., Audio-Technica.. The cost of simple models is from 500 to 1000 rubles. Audio handmade middle class will cost from 1500 to 3000 rubles. The prices of high-end models vary from 3500 to 13,000 rubles.
