Ingress protection ratings is the rating of protection given by an enclosure, against dust and water. In the format of IPXX, 'X' represents a number The first value of the IP rating represents protection against solids such as dust, while the second refers to protection against liquids (water).
Scoring IPX5, the Boult Audio Z40's rating is read as, the first number of X denotes that no data available to specify a protection rating, and of liquids that they can withstand medium pressure jet that's 6.3mm diameter, similar to garden hose from any angle for 3 minutes at a distance of 2.5 to 3 metres. Compared to the Boult Audio Z40, JBL Live Free 2 have a rating of IPX5 meaning that
we are not yet certain of their rating with solids (dust)
and that of liquids is that,
