Bowers & Wilkins PX7 S2 ✓

Sennheiser HD 350BT ✗

Twisted headphone cables can be a great source of annoyance and inconvenience, Bowers & Wilkins PX7 S2'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 completely damaging your headphones.

Cable Length

Bowers & Wilkins PX7 S2 1.2meters

Sennheiser HD 350BT ✗

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

Bowers & Wilkins PX7 S2 ✓

Sennheiser HD 350BT ✓

Over-ear headphones have larger earpads that fit around your entire ear Sennheiser HD 350BT 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.

Has Active Noise Cancellation (Anc)

Bowers & Wilkins PX7 S2 ✓

Sennheiser HD 350BT ✗

Active noise cancellation uses more advanced technology to actively counter noise. 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.

Bowers & Wilkins PX7 S2 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

Bowers & Wilkins PX7 S2 ✓

Sennheiser HD 350BT ✓

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 Sennheiser HD 350BT 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 Bowers & Wilkins PX7 S2 isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

Bowers & Wilkins PX7 S2 ✗

Sennheiser HD 350BT 18Hz

Low-frequency response measures if and how well a particular audio component reproduces low audible frequencies and if it makes any changes to the signal while at it. Sennheiser HD 350BT's lowest frequency is at 18Hz, the lower the low-frequency response, the stronger and juicier the bass.

Highest Frequency

Bowers & Wilkins PX7 S2 ✗

Sennheiser HD 350BT 22,000Hz

High frequency response measures if and how well an audio component reproduces high audible frequencies and if it makes any changes to the signal while at it. Sennheiser HD 350BT's highest frequency is at 22,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Sound Pressure Level

Bowers & Wilkins PX7 S2 ✗

Sennheiser HD 350BT 108dB/mW

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, Sennheiser HD 350BT's measurement is 108dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

Driver Unit Size

Bowers & Wilkins PX7 S2 40mm

Sennheiser HD 350BT 32mm

The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Sennheiser HD 350BT driver unit is 32mm in diameter, bigger drivers are more powerful and can produce better bass.

Bowers & Wilkins PX7 S2 driver unit is 40mm in diameter, making them have a larger driver unit than that of Sennheiser HD 350BT by 8mm , 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 produce better sound.

Impedance

Bowers & Wilkins PX7 S2 ✗

Sennheiser HD 350BT 32Ohms

Defined as the device's resistance to the electromagnetic current, as electricity flows through a conductor, it faces electrical resistance that counters the flow of current. The resistance of a conductor is measured in ohms. Sennheiser HD 350BT's impedance is 32Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.

Has A Neodymium Magnet

Bowers & Wilkins PX7 S2 ✗

Sennheiser HD 350BT ✓

Neodymium magnets if used in audio devices produce a higher sensitivity and substantial sound output using less power to do so. They can help produce music at quite a high sound pressure level, SPL, with the use of high magnetic flux. The Sennheiser HD 350BT have this type of magnet.
