IP ratings refer to the rank of protection given by an enclosure, against solids 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 protection against liquids (water).

Having a value of IPX4, the JBL Tune Flex's rating for solids indicates that no data available to specify a protection rating, 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 JBL Tune Flex, Sennheiser Momentum True Wireless 3 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

ANC uses more advanced technology to actively counter noise. How it works, it detects and analyzes the sound pattern of incoming noise and then generates a mirror signal to counter it. Simply put, it's like taking +1 (sound from your surrounding) and producing -1 (inverted noise) giving zero therefore "diluting" the noise.

JBL Tune Flex have Active Noise Cancellation allowing you to listen at lower levels of volume, good for your ears as you don't need to crank up the earbuds volume to outcompete background noise.
