Has Active Noise Cancellation (Noise Control)

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.

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.
Lowest Frequency
Anker Soundcore Liberty 3 Pro
20Hz
Bowers & Wilkins PI7 10Hz
Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response inidcates how well an audio device produces low frequencies that can be heard, and if it makes any changes to the signal on its way through.
Anker Soundcore Liberty 3 Pro's lowest frequency is at 20Hz, this implies that
Bowers & Wilkins PI7 produce a juicier bass than the Anker Soundcore Liberty 3 Pro
Highest Frequency
Anker Soundcore Liberty 3 Pro
40000Hz
Bowers & Wilkins PI7 20000Hz
Bowers & Wilkins PI7's highest frequency is at 20000Hz, high-frequency response shows how well a particular audio component produces high human frequencies and if it changes to the signal while at it.
Anker Soundcore Liberty 3 Pro's highest frequency is at 40000Hz, this means that
Anker Soundcore Liberty 3 Pro can generate a clearer and crispier treble than the Bowers & Wilkins PI7
Sound Pressure Level
Anker Soundcore Liberty 3 Pro
92dB/mW
Bowers & Wilkins PI7 ✗
SPL, is the pressure level of sound, measured 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.
