Ingress protection ratings is the rank of protection offered by a casing, against solids and liquids. In the format of IPXX, 'X' represents a number The first value of the IP rating refers to protection against solids such as dust, followed by the one that refers to protection against liquids (sweat).
Scoring IPX4, the Anker Soundcore Liberty 3 Pro's rating is read as, the first number of X denotes 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. In comparison to the Anker Soundcore Liberty 3 Pro, 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,

Active noise cancellation utilises more advanced kind of tech to reduce unwanted ambient sounds. ANC works when, it detects and analyzes the sound pattern of incoming noise and after inverts the soundwaves to counter it.
Simply put, it's like taking +1 (sound from your surrounding) and producing -1 (inverted noise) to make 0 resulting in a reduced level of noise.
Anker Soundcore Liberty 3 Pro have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears since you don't have to crank up the earbuds volume to overcome background noise.

both devices can produce equal treble
The sound pressure level, is the pressure level of sound, in decibels, dB, Anker Soundcore Liberty 3 Pro's measurement is 92dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source. Sony WF 1000XM4's sound pressure level measurement is 105dB/mW.
The sound pressure level, a device is can be perceived differently by separate people, so we need to have the means to get a standard measurement of sound level expressed in numerical terms. The Anker Soundcore Liberty 3 Pro's battery life is 8 hours, these last longer than 5 hours of listening which is considered average before recharge.
