Headphones that are designed to allow air to pass through their ear cups from the rear of the speaker driver unit are known as open-back. This design provides a very natural and accurate sound, Focal Bathys have this kind of design which means that resonances and low-frequency that tend to build up caused by the rear enclosure are no longer a concern.

Has Active Noise Cancellation (Anc)

Focal Bathys ✓

Sony WH CH520 ✗

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 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.

Has Passive Noise Reduction

Focal Bathys ✓

Sony WH CH520 ✓

Passive Noise Cancellation uses well-designed ear cups to seal out unwanted noise. This is used for both in-ear earphones and over-ear headphones where the headphone itself will keep surrounding noise out. The Sony WH CH520 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 Focal Bathys isolates you from ambient noise instead of actively using technology to cancel it out.

Highest Frequency

Focal Bathys 22000Hz

Sony WH CH520 20000Hz

High frequency response measures if and how well an audio component reproduces high audible frequencies and if it changes to the signal while at it. Sony WH CH520's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Focal Bathys's highest frequency is at 22000Hz, this means that Focal Bathys got a clearer and crispier treble than the Sony WH CH520

Driver Unit Size

Focal Bathys 40mm

Sony WH CH520 ✗

Has A Neodymium Magnet

Focal Bathys ✓

Sony WH CH520 ✗

Neodymium magnets when 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 Focal Bathys have this type of magnet.
