Has Active Noise Cancellation (Anc)
1More SonoFlow
✓
Bowers & Wilkins PX7 S2 ✓
Active noise cancellation uses more advanced technology to actively counter noise. How it works, it listens to the sound pattern of incoming noise and then inverts the soundwaves to cancel it out. In simple terms, it's like taking +1 outside (noise from your surrounding) and adding -1 inside (counter sound within the device) to make zero hence "diluting" the noise.
1More SonoFlow allow you to listen at lower volume levels, causing less ear fatigue as you don't have to crank up the volume to overcome background noise.
Bowers & Wilkins PX7 S2 too have active noise cancellation making both devices ideal for plane rides and morning commutes. Each may work with different noise cancellation modes, pick the setting, mode, or noise cancellation type that you prefer for commute or that enhances your relaxation time.
Has Passive Noise Reduction
1More SonoFlow
✓
Bowers & Wilkins PX7 S2 ✓
Passive Noise Cancellation uses well-designed ear cups to seal out environment noise. This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out.
The 1More SonoFlow sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.
Both of these devices have passive noise reduction which means that also the Bowers & Wilkins PX7 S2 isolates you from ambient noise instead of actively using technology to cancel it out.
Lowest Frequency
1More SonoFlow
20Hz
Bowers & Wilkins PX7 S2 ✗
Low-frequency response measures if and how well a particular audio device reproduces low audible frequencies and if it makes any changes to the signal on the way through. 1More SonoFlow's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.
Highest Frequency
1More SonoFlow
20,000Hz
Bowers & Wilkins PX7 S2 ✗
High frequency response measures if and how well an audio device reproduces high audible frequencies and if it makes any changes to the signal while at it. 1More SonoFlow's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Driver Unit Size
1More SonoFlow
40mm
Bowers & Wilkins PX7 S2 40mm
The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. 1More SonoFlow driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.
Bowers & Wilkins PX7 S2 driver unit is 40mm in diameter,
making both Bowers & Wilkins PX7 S2, and 1More SonoFlow similar in how loud their sound gets
, as many tend to believe that driver units of a bigger size automatically produce better sound quality.
However, large drivers usually have difficulty reproducing high frequencies so yes, larger drivers can generate louder sound, but this does not mean that they produce better sound.
Impedance
1More SonoFlow
32Ohms
Bowers & Wilkins PX7 S2 ✗
Defined as the device's resistance to the electromagnetic current, as electricity flows through a conductor, it experiences electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms. 1More SonoFlow's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
