Has Active Noise Cancellation (Noise Control)
1More Evo

Bowers & Wilkins PI7 ✓
Active noise cancellation makes use of advanced kind of tech to reduce unwanted ambient sounds. How it works, it studies the sound pattern of incoming noise and inverts the soundwaves to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) and adding -1 (counter sound by the device) to make 0 therefore "diluting" the noise.
The 1More Evo have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't need to crank up the earbuds volume to overcome background noise.
The Bowers & Wilkins PI7 too have Active Noise Cancellation making both earbuds ideal for plane rides and rush hour commutes. The 1More Evo and Bowers & Wilkins PI7 operate with different noise cancellation types, pick the mode that suits your commute or that enhances your relaxation time.

Bowers & Wilkins PI7 ✓
The 1More Evo sit well in place, creating a sound seal that reduces background sounds and also prevents the earbuds voice audio from leaking out at the same.
Both of these devices have passive noise reduction which implies that both limit ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
1More Evo
10mm
Bowers & Wilkins PI7 9.2mm
1More Evo driver unit is 10mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is basically a mini speaker that makes sound in the device, the unit size corellates with the sound produced by the device.
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
which means that they have a smaller driver unit than that of 1More Evo by 0.8mm
, many people have a misconception that driver units of a bigger size automatically produce better sound quality.
However, large drivers find it difficult to produce high frequencies so yeah, larger drivers are capable of generating louder sound, but this does not mean that they deliver better quality sound.
Lowest Frequency
1More Evo
20hz
Bowers & Wilkins PI7 10hz
1More Evo's lowest frequency is at 20Hz, low-frequency response inidcates how well a particular audio component generates low recognizable frequencies and if it alters the signal on its way through.
Bowers & Wilkins PI7's lowest frequency is at 10Hz, this implies that
Bowers & Wilkins PI7 produce a juicier bass than the 1More Evo
Highest Frequency
1More Evo
40,000hz
Bowers & Wilkins PI7 20,000hz
The 1More Evo's highest frequency is at 40,000Hz, high-frequency response indicates how well an audio device makes high human frequencies and if it makes any adjustments to the signal while at it.
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, this means that
1More Evo can generate a clearer and crispier treble than the Bowers & Wilkins PI7
