Has Active Noise Cancellation (Noise Control)

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.
Anker Soundcore Liberty 3 Pro too have ANC making both earbuds ideal for plane rides and morning travels. Each work with different noise cancellation settings, pick the mode that suits your travel or that enhances your relaxation time.

Driver Unit Size
Anker Soundcore Liberty 3 Pro
10.6mm
Bowers & Wilkins PI7 9.2mm
Bowers & Wilkins PI7 have a unit size of 9.2mm in diameter, the bigger the unit the more powerful, therefor producing better bass.

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
, 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.
Lowest Frequency
Anker Soundcore Liberty 3 Pro
20Hz
Bowers & Wilkins PI7 10Hz
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
Highest Frequency
Anker Soundcore Liberty 3 Pro
40000Hz
Bowers & Wilkins PI7 20000Hz
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.
Anker Soundcore Liberty 3 Pro's highest frequency is at 40000Hz, this implies that
Anker Soundcore Liberty 3 Pro generate a clearer and crispier treble than the Bowers & Wilkins PI7
Sound Pressure Level
Anker Soundcore Liberty 3 Pro
92dB/mW
Bowers & Wilkins PI7 ✗
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.
