Has Active Noise Cancellation (Noise Control)
Bowers & Wilkins PI7
✓
Nothing Ear 1 ✓
Active noise cancellation utilises advanced technology to actively cancel noise. ANC works when, it detects and analyzes the sound pattern outside and inside the earbud and then generates a mirror signal to cancel it out. Simply put, it's like taking +1 (sound from your surrounding) and adding -1 (inverted noise) giving zero therefore "diluting" the noise.
The Bowers & Wilkins PI7 have Active Noise Cancellation allowing you to listen at lower levels of volume, causing less ear fatigue since you don't have to crank up the earbuds volume to overcome background sounds.
Nothing Ear 1 too have ANC making either of the earbuds ideal for plane rides and morning commutes. The Bowers & Wilkins PI7 and Nothing Ear 1 operate with different noise cancellation modes, pick the mode that you prefer for travel or that suites your relaxation time.
Has Passive Noise Reduction

Nothing Ear 1 ✓
Bowers & Wilkins PI7 sit tightly in place, this creates a sound seal that reduces your environment noise while preventing the device music from leaking out at the same.
Both of these devices have passive noise reduction this means that they tone down ambient noise without using technology to cancel it out.
Driver Unit Size
Bowers & Wilkins PI7
9.2mm
Nothing Ear 1 11.6mm
The Bowers & Wilkins PI7 have a unit size of 9.2mm in diameter, the bigger the unit the more powerful, and can produce better bass.
The driver unit is basically a mini speaker that produces sound in the earbuds, the unit size corellates with the sound made by the device.
Nothing Ear 1 driver unit is 11.6mm in diameter,
making them have a larger driver unit than that of Bowers & Wilkins PI7 by 2.4mm
, a common assumption 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 are capable of generating louder sound, but this does not indicate that they produce better quality sound.
Lowest Frequency
Bowers & Wilkins PI7
10Hz
Nothing Ear 1 20Hz
Bowers & Wilkins PI7's lowest frequency is at 10Hz, low-frequency response measures if and how well an audio component produces low audible frequencies and if it alters the signal on its way through.
Nothing Ear 1's lowest frequency is at 20Hz, this implies that
Bowers & Wilkins PI7 produce a juicier bass than the Nothing Ear 1
Highest Frequency
Bowers & Wilkins PI7
20,000Hz
Nothing Ear 1 20,000Hz
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, high-frequency response indicates how well an audio device produces high human frequencies and if it makes any adjustments to the signal while at it.
Nothing Ear 1's highest frequency is at 20,000Hz, this means that
both devices produce equal treble
