Active noise cancellation uses more advanced technology to actively counter noise. How it works, it listens to the sound pattern outside and inside the earbud 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 0 resulting in a reduced level of noise.
Bowers & Wilkins PX7 S2 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.
Has Passive Noise Reduction

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 OneOdio Studio Wireless C 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.
Sound Pressure Level

OneOdio Studio Wireless C 110dB/mW
Sound pressure is the average variation in atmospheric pressure caused by the sound, the sound level .i.e how loud something is can be perceived differently by different people so we need to have a way of getting an objective measurement of sound level expressed in numerical terms.
The sound pressure level, SPL, is the pressure level of a sound, measured in decibels, dB, OneOdio Studio Wireless C's measurement is 110dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.
Driver Unit Size

40mm
OneOdio Studio Wireless C 50mm
The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. OneOdio Studio Wireless C driver unit is 50mm in diameter, bigger drivers are more powerful and can produce better bass.
Bowers & Wilkins PX7 S2 driver unit is 40mm in diameter,
which means that they have a smaller driver unit than that of OneOdio Studio Wireless C by 10mm
, many people have a misconception 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 deliver better sound.
Impedance

✗
OneOdio Studio Wireless C 32Ohms
Defined as the device's resistance to the electromagnetic current, as electricity flows through a wire, it experiences electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms. OneOdio Studio Wireless C's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.
Has A Neodymium Magnet

Neodymium magnets if used in audio devices produce a higher sensitivity and substantial sound output while using less power. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The OneOdio Studio Wireless C have this type of magnet.
