The summer heat has already arrived, and with it the desire to cool off on the beach or in the pool to the rhythm of our favorite music. At that time, wireless speakers took center stage and allowed us to turn our mobile or tablet into multimedia equipment. Teams that have significant enemies in the water and dust.

To avoid these elements, which could damage devices, more and more brands are offering protection certificates. Made up of two letters and an attached number, they indicate the degree of protection from which we will benefit and to dispel any doubt, we will detail what each of them consists of.

Are expensive headphones always better than cheap ones?

The importance of protecting yourself

It is about taking care of our devices to prevent them from being damaged by premature use due to the entry of elements such as water and dust. And this is achieved by creating small watertight compartments, well insulated from the outside. Thus come the degrees of protection, a value that appears on the box of all devices that have some type of insulation.

A degree of protection varies depending on the resistance offered by an enclosure against access to sensitive parts, solid foreign objects or the ingress of water and dust.

The protection of a device against external factors is determined by means of the well-known IP code. This indicator is the coding system used to mark the degrees of protection of devices against hazardous objects and substances. It consists of a code made up of the letters IP followed by two single-digit numbers and sometimes one or two optional letters.

With the first digit we will refer to the protection against access to dangerous parts of the device from solid foreign bodies. Thus, this first digit oscillates between the values ​​of 0 and 6 so that the higher the value indicates greater protection against smaller solid bodies.

For its part, the second number refers to the degree of protection offered by the enclosures against the effects caused by the ingress of water. The higher the number, the higher the degree of protection.

Protection against the ingress of water from all directions even in the event of strong pressure against the frame. (high pressure cleaner or steam jet, 80-100 bar)

With all this data, when buying a device and as they tell us from Motorola, we will see how the two digits are not always present and many manufacturers choose only one depending on the element against which they offer protection. These are the most common values ​​when it comes to determining water resistance, which is what interests us most for the summer:

IPX1 and IPX2 degrees: these degrees of protection strongly advise against exposure to water. They only protect for a short time against small drops of water falling vertically or at an angle of 15 °. For a vacation trip, a device with a higher degree of water resistance is recommended. IPX3 degree: devices with this degree of protection can withstand drops or splashes of water, falling on the device at an angle of 60 °. Rain, for example, is not dangerous for this type of headphones or speakers, but they could easily be damaged by water jets. IPX4 degree: at this point the devices begin to offer water resistance to consider. With IPX4, they have protection against water jets from any angle. They will be protected from rain and sweat, and can be used near swimming pools, taking precautions to prevent them from falling into the water. IPX5 and IPX6 grades: Audio devices with this type of protection can be directly subjected to strong and nearby jets of water. They can get wet without a problem and you can even use them in the shower, but avoid submerging them completely in water. Degrees IPX7 and IPX8 – The two highest resistance degrees in the rating allow full immersion of the device for at least 30 minutes. In the case of the IPX7, a depth of one meter is considered, while in the IPX8 it is the manufacturer who must specify the depth limit up to which no leakage will occur.

With this protection, we will find out how our devices are protected against certain conditions and we only have to know what these values ​​consist of to determine to what limit we can collect our gadgets without putting their integrity and our wallet at risk. .
