Headsets have three main options structure, each of which has the features:
Overhead are placed outside the pinna and have the greatest amount of all types. Their main advantage is rich sound, especially in the bass, but because it is they should pay attention to fans of high-quality sound. Disadvantage - large size, difficult to store and transport. Surface models can have different acoustic design - from the closed (with a maximum sound insulation) to open (with a minimum). In a noisy environment, or for maximum "immersive" handy closed type (for example, in computer games), and where it is desirable to hear sounds from the outside - open.
Inserts are designed exclusively for the portable equipment (eg, players). They have a small size and mounted in the ear outside of the ear canal. The main advantage is the compactness. However, the sound quality and sound insulation inserts are relatively low, they are designed mainly to undemanding users, as well as those for whom convenience is critical in storage and transport.
In-ear monitor similar to the inserts, but they are located outside and inside the ear canal. It provides a rich sound and good sound insulation in the same tiny size. This option is suitable for those who wish to combine a good sound quality and compactness.
Headphones are usually equipped with a headband, but there are models with temples for an individual mounting of each earphone to "his" ear - they are comfortable to wear with a cap or a complicated hairstyle. Inserts and intracanal headband does not have, but also can be equipped with arches - in this case, for more reliable fastening.
In general, any headphones before you buy should ideally try - as they will be comfortable.
By connecting headphones are divided into wired and wireless. In most cases it is enough of the first type, while the second can be recommended for those who require maximum ease of movement (so the wire does not interfere).
The optimal length of wire headphone will be different depending on the application. For mobile equipment is sufficient 1-1.5 m for the computer - at least 2, for TV studios and -. 3 m Wired model with a 3.5 mm plug is compatible with the absolute majority of modern audio equipment (including a "professional" yields 6.35 mm, with adapter), and models with USB are only designed for computers.
If sound quality is especially important - pay attention to the headphone frequency response: it is wider than the richer, as a rule, the reproduced sound. A useful system of active noise cancellation in noisy environments.
For outdoor enthusiasts, and those who have been in adverse conditions, produced a model with Ingress protection housing.
