IP ratings refer to the rank of protection given by a casing, against dust and water. The letters 'IP' are followed by two values The first value of the IP rating represents protection against solids such as dust, followed by the one that refers to resistance against liquids (water).
Scoring IPX5, the Boult Audio Z40's rating for solids indicates 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. In comparison to the Boult Audio Z40, JBL Reflect Aero have a rating of IP68 meaning that
they are completely dust proof
and that of liquids is that,
Boult Audio Z40 has a lower liquid rating than JBL Reflect Aero

The Boult Audio Z40's lowest frequency is at 20Hz, low-frequency response measures if and how well a particular audio component generates low audible frequencies and if it alters the signal on its way through. JBL Reflect Aero's lowest frequency is at 20Hz, this implies that
both devices can make sound with equal bass
The Boult Audio Z40's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio device generates high recognizable frequencies and if it makes any adjustments to the signal on its way through. JBL Reflect Aero's highest frequency is at 20,000Hz, this means that
both devices produce equal treble
