IPX7 waterproof definition

You can find many reviews of Bluetooth Waterproof Headphones on this site. Many of them are certified as IPX7. But what are ipx7 waterproof headphones?

IP code ( ingress protection ) identifies the resistance of electrical equipment against the intrusion of foreign objects (typically dust) and liquids. The code consists of a two-digit number, the first value indicating the degree of protection just before entering foreign objects and the second number indicating the degree of protection against water penetration. The maximum protection degree can be IP68.

The following tables provide a detailed description of the numbers:

Degree Dangerous touch Intrusion of foreign objects
IP 0x without protection without protection
IP 1x palms big ones
IP 2x finger small
IP 3x tool (> 2.5 mm) small ones
IP 4x tool, wire (> 1 mm) very small
IP 5x by any means dust partially
IP 6x by any means dust completely


Degree waterproof definition (IPX specification)
IPx0 without protection
IPx1 Protected against falling water at rain equivalent of 3 to 5 mm of falling water per minute over 10 minutes. The unit is located in its working position.
IPx2 Protected against falling water when the appliance is in the 15-degree position. Same as IP x1, except that the unit is tested in 4 positions, tilted 15 ° at each position from the normal operating position.
IPx3 Protected against water spray. Water sprays at 60 degrees vertically, at a rate of 10 liters per minute and a pressure of 80-100 kN / m2 for 5 minutes.
IPx4 Protected against splashing water. Same as for IP x3, except that the water sprays at all angles.
IPx5 Protected against splashing water. The water drives a 6.3 mm nozzle at all angles at a flow of 12.5 liters per minute at a pressure of 30 kN / m2 for 3 minutes from a distance of 3 meters.
IPx6 Protected against waves. The water is directed by a 12.5 mm nozzle at all angles at a flow of 100 liters per minute at a pressure of 100 kN / m2 for 3 minutes from a distance of 3 meters.
IPx7 Protected against immersion in water. Immersion for 30 minutes to a depth of 1 meter.
IPx8 Protected against sinking into the water. The device is capable of continuous immersion in water under conditions specified by the device manufacturer.


In practice, this means that if the device meets the protection class IP67, it is fully dustproof (numeral 6 in the label) while being protected against water penetration to a depth of one meter for 30 minutes (digit 7 in the name).

Some devices on the market meet IP57 protection. This in practice means that they are partially dust-proof and at the same time last for 30 minutes at a maximum depth of 1 meter without damaging them.
