IP ratings refer to the rating of protection offered by an enclosure, against dust and water. The letters 'IP' are followed by two values 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 AZ60'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 AZ60, Sony WF 1000XM4 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

Active noise cancellation uses advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it studies the sound pattern outside and inside the earbud and then inverts the soundwaves to counter it. Simply put, it's like having +1 (sound from your surrounding) then producing -1 (counter sound by the device) giving 0 hence "diluting" the noise.
