Pink Cellphone

The headphones are made of a flexible bow, metal or plastic, can offer comfort, as may be required several hours even on the ears. On either side of the bow are attached pavilions containing earphones. Headphones connected to an audio source via wires, or with new technologies that do not include the use, as described below. Typically, the earphones are made of: connector for the charger (if rechargeable and independent from the phone), multifunction button, volume control key, clip for the ear and microphone.

Mobile phones now in circulation are very numerous, and each of us possesses at least one. This object so loved / hated it has become almost an add-on of our body. If so has become an integral part of our life, we cannot do without, then try to use it intelligently.

Among the numerous of accessories for existing cellular, there is certainly a valuable headphones.
The headset, in its various forms and models, we shall see later, allows us to direct the sound directly to the ear, without interference, but also gives us the possibility of not having to hold the phone. Easy to imagine situations where it might be useful: every time for any reason our hands are occupied by shopping bags, from bags, or books, and especially when we’re driving. It ‘important fact for our safety and that of others, does not distract and keep your hands firmly on the steering wheel.

Of all the reasons why the use of the headset is recommended and highly recommended, one of the most important is to reduce the effect of radiation produced by the phone, very harmful to health, as we shall see later.

Reasons for use

As mentioned earlier, it is important to avoid using the headset, especially those radiation or other adverse effects that the phone can have on our person.
For some time talking about electromagnetic waves emanating from electronic devices are harmful to health, but then he actually knows little, and people continue to absorb them unconsciously.

As we know, people who use mobile phones significantly increase from year to year, including now even the children. These scientists have found that electromagnetic radiation emitted by mobile phones, like any other electronic device (TV, computer, etc..) can cause changes in human cells that affect the brain.

Let us go into detail to understand. The phones produce non-ionizing radiation, these radio frequencies, which represent a health hazard, if they exceed certain amounts. The level of exposure to such radiation depends on various factors including the quality of transmission, the size of the apparatus, the antenna length and above the amount of phone calls you make. The main source spectrum of a cell is, as you might think, right antenna. So this is more close to the head, the more one is exposed to radiation that produces heat, and removing it reduces the amount quickly.

Just think that after only two minutes of phone conversation phone impulses disable the safety and blood brain barrier that protects and insulates the brain from toxins in the blood. It appears from these studies that when the phone is switched on, the toxins in the blood can cross the barrier and reach the brain.

Therefore one can conclude that, in addition to seeking to reduce telephone traffic, you absolutely must try to keep as far as possible the antenna of the phone, then using the headset. Another reason to use this tool is if you have the habit of talking on the phone while driving a car.

The types of headphones available on the market are many, but the distinction is practically made between two broad types: with or without headset cable.
Earphones with wires are those described above, classical compound from the headphone speaker, wire and connector. Closely resemble the earbuds that were used for the Walkman and now we use with MP3 players.

Depending on the quality may have different characteristics, such as multifunction buttons and what to adjust the volume. There are three types: retractable, earbud and boom. In the first cable is rolled up into a special space and can be adjusted to suit your needs, without having to use force in its full length. In earbud headphones instead is introduced into the ear and the microphone is applied to the cable, with a small clip to attach the jacket or sweater.

It’s easy to find in the shops of mobile phones and accessories, as well as in supermarkets and large department of electronics, but usually are however already included in the packaging of mobile phones.
The wires are perhaps not very comfortable and practical, but if you do not have large claims this type of headset that is more suited to its function.

Wireless headset

Through the application of Bluetooth headsets has been created that allow a great expression of wireless mobility. In fact, with headphones and telephones that supports this type of technology you can make and receive calls while on the move without using wires and cables connected to the phone. This course allows a greater range of motion and removes the obstacle that sometimes the wires can be. Bluetooth technology also does not require that the two devices are necessarily facing each other, but simply that they are at a maximum distance of 10 meters.

These earphones have an ergonomic shape, are lightweight and flexible. Unlike the original which are equipped with an internal rechargeable battery, and therefore it is important to choose one compatible with your phone and who has the specific charger.

Their cost is a bit ‘higher than those with the wires, but these are easy to find everywhere. Before you buy remember to evaluate the ergonomics, battery life and guarantees, of course cost that varies from model to model. Be aware that there may be restrictions on using bluetooth in some countries, and that you should never leave magnetic storage media and credit cards too close to the headset, it may be demagnetized.
