Ingress protection ratings refer to the level 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 represents protection against solids such as dust, followed by the one that refers to protection against liquids (sweat).

Having a value of IP54, the Momentum True Wireless 4's rating is read as, the first value of 5 denotes that ingress of dust is not totally prevented but dust does not enter in harmful quantities to interfere with the correct operation or impair safety, and the second value of 4 means that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes. Compared to the Momentum True Wireless 4, Technics EAH AZ80 have a rating of IPX4 meaning that no data available to specify a protection rating and that of liquids is that, they both have the same rating against liquids Momentum True Wireless 4 have a weight of 12.4g . We prefer a lower weight best for the reason that lighter devices are more comfortable to carry.

Technics EAH AZ80, at 14g are heavier than the Momentum True Wireless 4 by of 1.6g For a device to be true wireless it should have no wires linking any part of the device together, Momentum True Wireless 4 are true wireless for this case since they don't have cables.
