Has Active Noise Cancellation (Anc)
Bowers & Wilkins PX7 S2

Focal Bathys ✓
Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it listens to the sound pattern of incoming noise and then generates a mirror signal 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 hence "diluting" the noise.
Focal Bathys 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 suits your commute or that enhances your relaxation time.
Has Passive Noise Reduction

Focal Bathys ✓
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 Focal Bathys 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
Bowers & Wilkins PX7 S2
✗
Focal Bathys 15Hz
Low-frequency response measures if and how well a particular audio component reproduces low audible frequencies and if it makes any changes to the signal while at it. Focal Bathys's lowest frequency is at 15Hz, the lower the low-frequency response, the stronger and juicier the bass.
Highest Frequency
Bowers & Wilkins PX7 S2
✗
Focal Bathys 22000Hz
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. Focal Bathys's highest frequency is at 22000Hz, the higher the high-frequency response, the clearer and crispier the treble.
Driver Unit Size

40mm
Focal Bathys 40mm
The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. Focal Bathys 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 devices 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 are capable of generating louder sound, but this does not mean that they produce better sound.
Has A Neodymium Magnet

Focal Bathys ✓
Neodymium magnets when used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The Focal Bathys have this type of magnet.
