A breakdown of the review per specifications

Design

Ingress Protection (Ip) Rating

Anker Soundcore Liberty 3 Pro IPX4
Sennheiser CX 500BT IPX4

Ingress protection ratings refer to the rating of protection offered by a casing, against dust and water. The letters 'IP' are followed by two values The first value of the IP rating means protection against solids say dust, while the second refers to resistance against liquids (sweat).

Scoring IPX4, the Sennheiser CX 500BT's rating for solids indicates that no data available to specify a protection rating, and of liquids that they can withstand low pressure spray similar to that of a shower head when tilted at 180° for 10 minutes.

Compared to the Sennheiser CX 500BT, Anker Soundcore Liberty 3 Pro 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

Sound Quality

Has Active Noise Cancellation (Noise Control)

Anker Soundcore Liberty 3 Pro
Sennheiser CX 500BT

ANC makes use of advanced technology to actively cancel noise. How it works, it detects and analyzes the sound pattern outside and inside the earbud and after inverts the soundwaves to counter it. In simple terms, it's like having +1 (sound from your surrounding) then producing -1 (inverted noise) to make zero thus "diluting" the noise.

The Sennheiser CX 500BT have ANC allowing you to listen at lower volume levels, causing less ear fatigue since you don't need to crank up the device volume to outcompete background sounds.

Anker Soundcore Liberty 3 Pro too have ANC making both devices ideal for flights and morning travels. The Sennheiser CX 500BT and Anker Soundcore Liberty 3 Pro operate with different noise cancellation types, pick the mode that you prefer for travel or that suites your relaxation time.
