Has Active Noise Cancellation (Anc)

Sony WH CH520 ✗

Bose QuietComfort 45 ✓

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 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.

Bose QuietComfort 45 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

Sony WH CH520 ✓

Bose QuietComfort 45 ✓

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 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 Bose QuietComfort 45 isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

Sony WH CH520 20Hz

Bose QuietComfort 45 ✗

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. Sony WH CH520's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.

Highest Frequency

Sony WH CH520 20,000Hz

Bose QuietComfort 45 ✗

High frequency response measures if and how well a particular audio component reproduces high audible frequencies and if it changes to the signal on the way through. Sony WH CH520's highest frequency is at 20,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Sound Pressure Level

Sony WH CH520 97dB/mW

Bose QuietComfort 45 ✗

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, Sony WH CH520's measurement is 97dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

Driver Unit Size

Sony WH CH520 30mm

Bose QuietComfort 45 40mm

The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Sony WH CH520 driver unit is 30mm in diameter, bigger drivers are more powerful and can produce better bass.

Bose QuietComfort 45 driver unit is 40mm in diameter, making them have a larger driver unit than that of Sony WH CH520 by 10mm , 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 it's true that, larger drivers are capable of generating louder sound, but this does not mean that they deliver better sound.

Impedance

Sony WH CH520 35Ohms

Bose QuietComfort 45 ✗

Impedance is the device's resistance to the electromagnetic current, when electricity flows through a wire, it experiences electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms. Sony WH CH520's impedance is 35Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.

Has A Neodymium Magnet

Sony WH CH520 ✓

Bose QuietComfort 45 ✗

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 Sony WH CH520 have this type of magnet.
