A breakdown of the review per specifications



Sony WH CH720N 192g
Bose QuietComfort 45 240g

Sony WH CH720N have a weight of 192g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We prefer a lower weight best for the reason that lighter devices are more comfortable to move with.

The Bose QuietComfort 45, at 240g are heavier than the Sony WH CH720N with a difference 48g

Has A Detachable Cable

Sony WH CH720N
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 an audio source. Some new headphones, and not just the expensive ones, are coming with detachable cables, Sony WH CH720N are one of those.

With a detachable cable, Bose QuietComfort 45 too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.

Can Be Folded

Sony WH CH720N
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 CH720N
Bose QuietComfort 45

Twisted headphone cables can be a great source of annoyance and inconvenience, Sony WH CH720N'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.

Cable Length

Sony WH CH720N 1.2meters
Bose QuietComfort 45

A long cable ensures more freedom of movement, but remember that every cable based on the conducting material used has a certain amount of parasitic resistance, inductance, and capacitance. How much depends on the length and construction. Sony WH CH720N comes with a 1.2meters cable.

Has An Over-The-Ear Foam

Sony WH CH720N
Bose QuietComfort 45

Over-ear headphones have larger earpads that fit around your entire ear Sony WH CH720N 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.

Bose QuietComfort 45 with this design offer potential for maximum bass and loudness levels.

Has Stereo Speakers

Sony WH CH720N
Bose QuietComfort 45

Sony WH CH720N have stereo speakers, what this means is that Sony WH CH720N's speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience.

The Bose QuietComfort 45 also have stereo speakers

Sound Quality

Has Active Noise Cancellation (Anc)

Sony WH CH720N
Bose QuietComfort 45

Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds. How it works, it detects and analyzes 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 zero hence "diluting" the noise.

Sony WH CH720N 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.

Bose QuietComfort 45 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

Sony WH CH720N
Bose QuietComfort 45

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 CH720N 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 CH720N 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 while at it. Sony WH CH720N's lowest frequency is at 20Hz, the lower the low-frequency response, the stronger and juicier the bass.

Highest Frequency

Sony WH CH720N 20000Hz
Bose QuietComfort 45

High frequency response measures if and how well a particular audio device reproduces high audible frequencies and if it changes to the signal on the way through. Sony WH CH720N's highest frequency is at 20000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Sound Pressure Level

Sony WH CH720N 99dB/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 CH720N's measurement is 99dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

Driver Unit Size

Sony WH CH720N 30mm
Bose QuietComfort 45 40mm

The driver unit is basically a mini speaker that produces sound in the device, its size dictates the loudness of the headphone. Sony WH CH720N 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 CH720N 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 yeah, larger drivers can generate louder sound, but this does not mean that they deliver better sound.


Sony WH CH720N 31Ohms
Bose QuietComfort 45

Defined as 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 conductor is measured in ohms. Sony WH CH720N's impedance is 31Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.


Battery Life

Sony WH CH720N 50hours
Bose QuietComfort 45 24hours

If your headphones play wirelessly, cancel ambient noise, or enhance your listening experience with active features, their battery life will reduce over time.
