IPX7 is a rating that indicates the level of water resistance of an electronic device. Specifically, it means that the device can be submerged in water up to 1 meter deep for 30 minutes without being damaged. This rating is one of the highest levels of water resistance and is commonly found on recent outdoor speaker models, smartphones, smartwatches, and other electronic gadgets. It is important to note that the IPX7 rating only applies to water resistance and does not indicate protection against dust or other solid objects.
