Sennheiser Momentum 4 Wireless Vs. Bowers & Wilkins Px7 S2 Review In Detail

Design

Weight

Sennheiser Momentum 4 Wireless 293g
Bowers & Wilkins PX7 S2 307g

Sennheiser Momentum 4 Wireless have a weight of 293g, 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.

The Bowers & Wilkins PX7 S2, at 307g weigh more than the Sennheiser Momentum 4 Wireless by 14g

Has A Detachable Cable

Sennheiser Momentum 4 Wireless
Bowers & Wilkins PX7 S2

Detachable cables are cables that have connectors on both ends. One end goes into your headphone cups, while the other end is inserted into a source device. Some new headphones, and not just the expensive ones, are coming with detachable cables, Sennheiser Momentum 4 Wireless are one of those.

With a detachable cable, Bowers & Wilkins PX7 S2 too can use alternative cables and if the cable is pulled, it will pop out instead of breaking.

Can Be Folded

Sennheiser Momentum 4 Wireless
Bowers & Wilkins PX7 S2

Bowers & Wilkins PX7 S2 are foldable, which makes them more portable. Foldable headphones are easier to transport and take up less storage space.

Has A Tangle Free Cable

Sennheiser Momentum 4 Wireless
Bowers & Wilkins PX7 S2

Twisted headphone cables can be a great source of annoyance and inconvenience, Sennheiser Momentum 4 Wireless's cable is designed to minimize tangling. Constant twisting of the cables can also lead to microfractures in the copper wires, affecting sound quality, or rendering your headphones defective.

Bowers & Wilkins PX7 S2 too have a cable designed to help prevent tangles.

Cable Length

Sennheiser Momentum 4 Wireless
Bowers & Wilkins PX7 S2 1.2meters

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 PX7 S2 comes with a 1.2meters cable.

Has An Over-The-Ear Foam

Sennheiser Momentum 4 Wireless
Bowers & Wilkins PX7 S2

Over-ear headphones have larger earpads that fit around your entire ear Sennheiser Momentum 4 Wireless 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.

Bowers & Wilkins PX7 S2 with this design offer potential for maximum bass and loudness levels.

Has Stereo Speakers

Sennheiser Momentum 4 Wireless
Bowers & Wilkins PX7 S2

Sennheiser Momentum 4 Wireless have stereo speakers, what this means is that Sennheiser Momentum 4 Wireless's speakers deliver sound from independent channels on both left and right sides, this creates a richer sound and a better listening experience.

Both Bowers & Wilkins PX7 S2 and Sennheiser Momentum 4 Wireless have stereo speakers

Sound Quality

Has Active Noise Cancellation (Anc)

Sennheiser Momentum 4 Wireless
Bowers & Wilkins PX7 S2

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 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 resulting in a reduced level of noise.

Sennheiser Momentum 4 Wireless 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.

Bowers & Wilkins PX7 S2 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

Sennheiser Momentum 4 Wireless
Bowers & Wilkins PX7 S2

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 Bowers & Wilkins PX7 S2 sits tightly in place, creating an acoustic seal that reduces background noise and prevents your music from leaking out.

Lowest Frequency

Sennheiser Momentum 4 Wireless 6Hz
Bowers & Wilkins PX7 S2

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. Sennheiser Momentum 4 Wireless's lowest frequency is at 6Hz, the lower the low-frequency response, the stronger and juicier the bass.

Highest Frequency

Sennheiser Momentum 4 Wireless 22,000Hz
Bowers & Wilkins PX7 S2

High frequency response measures if and how well an audio device reproduces high audible frequencies and if it changes to the signal on the way through. Sennheiser Momentum 4 Wireless's highest frequency is at 22,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Sound Pressure Level

Sennheiser Momentum 4 Wireless 106dB/mW
Bowers & Wilkins PX7 S2

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, Sennheiser Momentum 4 Wireless's measurement is 106dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

Driver Unit Size

Sennheiser Momentum 4 Wireless 42mm
Bowers & Wilkins PX7 S2 40mm

The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Sennheiser Momentum 4 Wireless driver unit is 42mm in diameter, bigger drivers are more powerful and can produce better bass.

Bowers & Wilkins PX7 S2 driver unit is 40mm in diameter, which means that they have a smaller driver unit than that of Sennheiser Momentum 4 Wireless by 2mm , 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 yes, larger drivers are capable of generating louder sound, but this does not mean that they deliver better sound.

Impedance

Sennheiser Momentum 4 Wireless 60Ohms
Bowers & Wilkins PX7 S2

Defined as the device's resistance to the electromagnetic current, as electricity flows through a wire, it faces electrical resistance that counters the flow of current. The resistance of a wire is measured in ohms. Sennheiser Momentum 4 Wireless's impedance is 60Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.

Has A Neodymium Magnet

Sennheiser Momentum 4 Wireless
Bowers & Wilkins PX7 S2

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 Sennheiser Momentum 4 Wireless have this type of magnet.

Power

Battery Life

Sennheiser Momentum 4 Wireless 60hours
Bowers & Wilkins PX7 S2 30hours

If your headphones play wirelessly, cancel ambient noise, or enhance your listening experience with active features, their battery life will reduce over time. The device's battery life is given by the manufacturer, with longer battery life, you get to use it for longer and have to charge the device less often. Sennheiser Momentum 4 Wireless's battery life is 60 hours

Bowers & Wilkins PX7 S2's battery life is 30 hours. Each time you recharge your headphones, they get a little less listening time. The effect is barely noticeable at first. But over a few years, you may find that your device, no longer plays for long like it used to.

Charge Time

Sennheiser Momentum 4 Wireless 2hours
Bowers & Wilkins PX7 S2 2hours
