Waterproof IP ratings

When looking for a waterproof Bluetooth speaker, it is important to know what the IP ratings mean. IP stands for “Ingress Protection” and it measures how well a device is protected from liquids and solids. 

An IP rating is given to a product that undergoes testing by a certified, independent company. 

The rating will have the IP designation, and then a number for solids and a number for liquids. 

The higher the number for solids between 0 – 6, the better the protection. The higher the number for liquids between 0 – 8, the better the protection. 

If a product had an IP rating of IP00, it would have no protection against liquids or solids. If a product had an IP rating of IP68, it would be the best protection you could get for solids and liquids. 

IP Ratings:

  • IPX0: The device offers no protection or resistance to water
  • IPX1: The device protects against small vertical drops of water
  • IPX2: The device offers protection from water dripping from a 15-degree angle
  • IPX3: The device provides protection from finely sprayed water
  • IPX4: The device offers protection from splashing water
  • IPX5: The device will protect against low-pressure jets of water coming from every direction
  • IPX6: The device provides protection from strong jets of water, ideal for use on ship decks
  • IPX7: The device is waterproof when submerged in water up to 1 meter
  • IPX8: The device is waterproof when submerged for long periods of time at depths greater than 1 meter
