A breakdown of the review per specifications

Bowers & Wilkins Px8 320g
Bose QuietComfort 45 240g

Bowers & Wilkins Px8 have a weight of 320g, these weigh below 320g, which we consider as the highest average a headphone should weigh for comfort during long use. We consider a lower weight better because lighter devices are more comfortable to move with.

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, Bowers & Wilkins Px8 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

Bowers & Wilkins Px8
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

Bowers & Wilkins Px8
Bose QuietComfort 45

Twisted headphone cables can be a great source of annoyance and inconvenience, Bowers & Wilkins Px8'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 completely damaging your headphones.

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

Cable Length

Bowers & Wilkins Px8 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. Bowers & Wilkins Px8 comes with a 1.2meters cable.

Has An Over-The-Ear Foam

Bowers & Wilkins Px8
Bose QuietComfort 45

Over-ear headphones have larger earpads that fit around your entire ear Bowers & Wilkins Px8 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.

Sound Quality

Has Active Noise Cancellation (Anc)

Bowers & Wilkins Px8
Bose QuietComfort 45

Active noise cancellation uses more advanced technology to actively counter noise. How it works, it detects and analyzes 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 resulting in a reduced level of noise.

Bowers & Wilkins Px8 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 you prefer for commute or that enhances your relaxation time.

Has Passive Noise Reduction

Bowers & Wilkins Px8
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 Bowers & Wilkins Px8 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.

Driver Unit Size

Bowers & Wilkins Px8 40mm
Bose QuietComfort 45 40mm

The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Bowers & Wilkins Px8 driver unit is 40mm in diameter, bigger drivers are more powerful and can produce better bass.

Bose QuietComfort 45 driver unit is 40mm in diameter, making both Bose QuietComfort 45, and Bowers & Wilkins Px8 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 it's true that, larger drivers are capable of generating louder sound, but this does not mean that they deliver better sound.

Battery Life

Bowers & Wilkins Px8 30hours
