IPX5 is an ingress protection rating that indicates the resistance of electronic devices, such as headphones or speakers, against water ingress. The letter „X“ in the first position means that the device has not been tested for protection against the ingress of solid particles, such as dust. The digit „5“ then specifies that the product is protected against jetting water from any direction. In practice, this means that the device can easily withstand heavy rain, sweat during sports, or rinsing under running water, but it is not designed for submersion.
