Has Active Noise Cancellation (Noise Control)
Razer Hammerhead True Wireless Pro
✓
Bowers & Wilkins PI7 ✓
ANC utilises advanced technology to actively counter noise. ANC works when, it studies the sound pattern outside and inside the earbud and after generates a mirror signal to cancel it out. In simple terms, it's like having +1 (noise) and producing -1 (counter sound by the device) giving zero hence "diluting" the noise.
The Razer Hammerhead True Wireless Pro have Active Noise Cancellation enabling you to listen at lower levels of volume, good for your ears as you don't need to crank up the device volume to overcome background noise.
Bowers & Wilkins PI7 too have Active Noise Cancellation which makes either of the devices ideal for flights and morning commutes. Each work with different noise cancellation settings, pick the mode that suits your travel or that suites your chill time.
Has Passive Noise Reduction

The Razer Hammerhead True Wireless Pro sit well in place, this creates a sound covering that tones down background noise and also prevents the earbuds voice audio from leaking out .
Both Bowers & Wilkins PI7, and Razer Hammerhead True Wireless Pro have passive noise reduction which implies that both tone down ambient noise instead of actively using technology to cancel it out.
Driver Unit Size
Razer Hammerhead True Wireless Pro
10mm
Bowers & Wilkins PI7 9.2mm
The Razer Hammerhead True Wireless Pro have a unit size of 10mm in diameter, bigger drivers are more powerful, and can produce better bass.
A driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the earbuds.
Bowers & Wilkins PI7 driver unit is 9.2mm in diameter,
which implies that they have a smaller driver unit than that of Razer Hammerhead True Wireless Pro by 0.8mm
, 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 it's true that, larger drivers are capable of generating louder sound, but this does not indicate that they deliver better quality sound.
Lowest Frequency
Razer Hammerhead True Wireless Pro
20hz
Bowers & Wilkins PI7 10hz
The Razer Hammerhead True Wireless Pro's lowest frequency is at 20Hz, low-frequency response measures if and 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.
Bowers & Wilkins PI7's lowest frequency is at 10Hz, this implies that
Bowers & Wilkins PI7 make sound with a juicier bass than the Razer Hammerhead True Wireless Pro
Highest Frequency
Razer Hammerhead True Wireless Pro
20,000hz
Bowers & Wilkins PI7 20,000hz
Razer Hammerhead True Wireless Pro's highest frequency is at 20,000Hz, high-frequency response tells how well an audio device generates high human frequencies and if it adjustments to the signal on its way through.
Bowers & Wilkins PI7's highest frequency is at 20,000Hz, this implies that
both devices produce equal treble
