A breakdown of the review per specifications

Design

Ingress Protection (Ip) Rating

Anker Soundcore Liberty 3 Pro IPX4
Bowers & Wilkins PI7 IP54

Ingress protection 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 represents protection against solids say dust, followed by the one that refers to protection against liquids (water).

Scoring IP54, the Bowers & Wilkins PI7's rating for solids indicates 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 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 Bowers & Wilkins PI7, Anker Soundcore Liberty 3 Pro 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

Sound Quality

Has Active Noise Cancellation (Noise Control)

Anker Soundcore Liberty 3 Pro
Bowers & Wilkins PI7

Active noise cancellation uses advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes the sound pattern of incoming noise and generates a mirror signal to counter it. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make zero resulting in a reduced level of noise.

The Bowers & Wilkins PI7 have ANC enabling you to listen at lower volume levels, causing less ear fatigue as you don't need to crank up the earbuds volume to overcome background noise.

The Anker Soundcore Liberty 3 Pro too have ANC which makes both earbuds ideal for plane rides and rush hour travels. The Bowers & Wilkins PI7 and Anker Soundcore Liberty 3 Pro operate with different noise cancellation settings, pick the mode that suits your commute or that enhances your chill time.

Has Passive Noise Reduction

Driver Unit Size

Anker Soundcore Liberty 3 Pro 10.6mm
Bowers & Wilkins PI7 9.2mm

Bowers & Wilkins PI7 driver unit is 9.2mm in diameter, bigger drivers are more powerful, therefor producing better bass. The driver unit is the component that makes sound in the earbuds, its size corellates with the loudness of the earbuds.

Anker Soundcore Liberty 3 Pro driver unit is 10.6mm in diameter, making them have a larger driver unit than that of Bowers & Wilkins PI7 by 1.4mm , a common assumption that driver units of a bigger size automatically produce better sound quality.

However, large drivers find it difficult to produce high frequencies so yes, larger drivers are capable of generating louder sound, but this does not imply that they produce better quality sound.
