Earlier than shopping for a pair of waterproof headphones, it is vital to work out whether or not the pair in query shall be immune to the water situations you will want them for. The principle means producers measure this resistance is thru an ingress safety (IP) score, which measures safety towards each mud and water. The IP score will normally take the type of both a two-digit quantity (for instance, IP68) or a single digit with an X (say, IPX7). The primary digit pertains to mud safety, whereas the second digit pertains to waterproofing, so it is the vital one right here. The X is not something to fret about — it merely means the producer hasn’t examined the gadget for that exact kind of safety, so within the case of an IPX7 score, mud ingress safety hasn’t been measured.
Scores lower than IPX5 shouldn’t be thought-about waterproof in any respect, and any product with both IPX5 or IPX6 scores will solely have the ability to stand up to water spray, not submersion of any type. IPX7 is what most individuals would take into account true waterproofing, for the reason that product will have the ability to stand up to submersion in water for half-hour at depths of as much as 1 meter (roughly 3 ft). IPX8 is the highest stage present in most commercially-available headphones, which means they are often submerged deeper than 3 ft, with the precise limitations specified by the producer.
