Sony Wh Ch520 Vs. Bose Quietcomfort 45 Review In Detail



Sony WH CH520 147g
Bose QuietComfort 45 240g

Sony WH CH520 have a weight of 147g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We take in account a lower weight best because lighter devices are more comfortable to carry.

The Bose QuietComfort 45, at 240g weigh more than the Sony WH CH520 with a difference 93g

Has A Detachable Cable

Sony WH CH520
Bose QuietComfort 45

Detachable cables are cables that have connectors on both ends. One end goes into your headphone earpieces, while the other end is inserted into a source device. Some new headphones, and not just the expensive ones, are coming with detachable cables, Bose QuietComfort 45 are one of those.

Can Be Folded

Sony WH CH520
Bose QuietComfort 45

Bose QuietComfort 45 are foldable, which makes them more portable. Foldable headphones are easier to transport and take up less storage space.

Has A Tangle Free Cable

Sony WH CH520
Bose QuietComfort 45

Twisted headphone cables can be a great source of annoyance and inconvenience, Sony WH CH520's cable is designed to minimize tangling. Constant twisting of the cables can also lead to bends in the copper wires, affecting sound quality, or rendering your headphones defective.

Bose QuietComfort 45 too have a cable designed to help prevent tangles.

Sweat Resistance

Sony WH CH520
Bose QuietComfort 45

By sweat resistance we mean that the wireless earbuds are protected in the presence of low-pressure water jets at any angle, this is determined by the IP Rating of the earbuds. Based on the ingress protection rating of the Sony WH CH520 they do have sweat resistance

Has An Over-The-Ear Foam

Sony WH CH520
Bose QuietComfort 45

Over-ear headphones have larger earpads that fit around your entire ear Bose QuietComfort 45 have a comfortable full-size form with earcups that fully enclose your ears. This design is loved for its increased sound isolation and the fact that it won't leak sound to your neighbors.

Sound Quality

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 outside and inside the earbud 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 resulting in a reduced level of 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 an audio component 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 an audio component reproduces high audible frequencies and if it makes any 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 the means to get 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 , 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 it's true that, larger drivers can generate louder sound, but this does not mean that they produce better sound.


Sony WH CH520 35Ohms
Bose QuietComfort 45

Impedance is 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. 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 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 Sony WH CH520 have this type of magnet.


Battery Life
