Ingress protection ratings refer to the rank of protection offered by an enclosure, against dust and liquids. In the format of IPXX, 'X' represents a number The first value of the IP rating means protection against solids such as dust, followed by the one that refers to resistance against liquids (sweat).
Having a value of IPX4, the Technics EAH AZ100's rating for solids indicates that no data available to specify a protection rating, and the second number of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. In comparison to the Technics EAH AZ100, Bose SoundSport Free have a rating of IPX4 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,
they both have the same rating against liquids
