Overall Score 7.2 Represents average audio ecosystem compatibility score.
Overall Score 6.4 Represents average audio ecosystem compatibility score.
Ingress protection ratings is the rating of protection offered by an enclosure, against dust and water. In the format of IPXX, 'X' represents a number The first value refers to protection against solids such as dust, while the second refers to resistance 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 the second number 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 Bowers & Wilkins PI7, Anker Soundcore Liberty 3 Pro have a rating of IPX4 meaning that
no data available to specify a protection rating

The Anker Soundcore Liberty 3 Pro also have stereo speakers
Active noise cancellation utilises advanced technology to actively cancel noise. How it works, it detects and analyzes the sound pattern of incoming noise and after generates a mirror signal to counter it. In simple terms, it's like having +1 (sound from your surrounding) and adding -1 (inverted noise) to make zero which results in a reduced level of noise.
The Bowers & Wilkins PI7 have ANC allowing you to listen at lower volume levels, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background noise.

making them have a larger driver unit than that of Bowers & Wilkins PI7 by 1.4mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty producing high frequencies so yes, larger drivers can generate louder sound, but this does not mean that they deliver better quality sound.
The Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response measures if and how well a particular audio device produces low audible frequencies and if it alters the signal on its way through.
Anker Soundcore Liberty 3 Pro's lowest frequency is at 20Hz, this implies that
Bowers & Wilkins PI7 can produce a juicier bass than the Anker Soundcore Liberty 3 Pro
The Bowers & Wilkins PI7's highest frequency is at 20000Hz, high-frequency response measures if and how well an audio component makes high audible frequencies and if it changes to the signal while at it.
