What are headphones?

headphones are wearable, stereo, miniaturized speaker systems.

The traditional headphones were relatively large and bulky, consisting of the left and right speakers contained in padded eggs called ears. The cups were attached to a secret headband that supported the leaving wire of the left right speaker. Following each ear cup was a signal conductor of the left or right channel, connected at the intersection and created a single stereo cable with a connector. The connector joined the headphone connector.

Today's headphones have gone a long way from the bulky sets of previous years. Lightweight, portable headphones, called ears , are almost imperceptible. Rather than the old headband, these small speakers sit inside the ear opening itself. The connection is much thinner and more flexible, which allows a more comfortable and pleasant experience.

There are several types of headphones for each purpose today. The vast majority of headphones sold to the wide publicis hi-t are usedEch gadgets such as personal sound players. Mobile phones can also be used with a headset, which consists of a single mono and miniature microphone. The headset connects to the phone to allow the hands-free operation of the phone.

There are two main styles for earphones for stereo use: those that fit freely in the ear; And those who have a small flexible arm that wakes over the ear to hold the bud in place. The latter style is great for active use, such as jogging, eating, skating or skiing. The first is advantageous for quiet activities such as walking or home use. The headphones for headphones are very cheap and a decent couple costs only $ 10 (US dollars).

advantage of headphone headphones for personal activities is that one can enjoy high loyalty and at the same time maintain a certain amount of audible consciousness freethe middle environment. The ears do not block all thexic sound so that the wearer can be aware of things such as traffic or other people.

For those who want to use headphones in a noisy environment, it may be desirable to block part of this external noise. In this case, the isolation of sound insulation or may be desirable.

Some headphones suppressing noise use headphones with foam or plastic sleeves to fit in ear, such as ear zate. This design passively and without difference blocks most of the external noise. Another style uses ear cups equipped with an external microphone for the sample of the surrounding noise. Based on the sample, the headphones generate mirror image wool to cancel the undesirable noise discrimination . This is useful in an environment such as the metro, where it wants to block mechanical noise and drone, yet heard a wire announcement that passes through the barrier of sound interference. The disadvantage of these headphones is that they are operated by the battery. They are also expensive.

Another inoVace is wireless headphones that use the base of the transmitter to pass the signals to the headset, eliminating the need for conductors. For example, it releases the wearer to go through the house while listening to the entertainment center.

Finally, traditional style, high -quality headphones for professional use in recording and musical environments are also available. These will use ears cups to block competitive noise.

Loyalty varies greatly between headphones. Some sets will emphasize the bass, but too many bass without a sufficient amount of medium and high frequencies will cause muddy sound. More often, headphones can miss bass, but decent headphones will bring high quality, satisfactory sound.
