Twisted headphone cables can be a great source of annoyance and inconvenience, Sennheiser HD 450BT'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.

Bang & Olufsen Beoplay Portal too have a cable designed to help prevent tangles.

Has An Open-Back Design

Sennheiser HD 450BT
Bang & Olufsen Beoplay Portal

Headphones that are designed to allow air to pass through their ear cups from the rear of the speaker driver unit are known as open-back. This design provides a very natural and accurate sound, Bang & Olufsen Beoplay Portal have this kind of design which means that resonances and low-frequency that tend to build up caused by the rear enclosure are no longer a concern.

Cable Length

Sennheiser HD 450BT 1.5meters
Bang & Olufsen Beoplay Portal 1.25meters

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. Sennheiser HD 450BT comes with a 1.5meters cable.

Bang & Olufsen Beoplay Portal comes with a 1.25meters cable. Almost any cable should be fine in sound quality If you're looking at lengths up to 2 - 3 meters.

Sound Quality

Has Active Noise Cancellation (Anc)

Sennheiser HD 450BT
Bang & Olufsen Beoplay Portal

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 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 HD 450BT 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.

Bang & Olufsen Beoplay Portal 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 HD 450BT
Bang & Olufsen Beoplay Portal

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 Sennheiser HD 450BT 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 Bang & Olufsen Beoplay Portal isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

Sennheiser HD 450BT 18Hz
Bang & Olufsen Beoplay Portal 20Hz

Low-frequency response measures if and how well an audio device reproduces low audible frequencies and if it makes any changes to the signal on the way through. Sennheiser HD 450BT's lowest frequency is at 18Hz, the lower the low-frequency response, the stronger and juicier the bass.

Bang & Olufsen Beoplay Portal's lowest frequency is at 20Hz, this implies that Bang & Olufsen Beoplay Portal got a juicier bass than the Sennheiser HD 450BT

Highest Frequency

Sennheiser HD 450BT 22,000Hz
Bang & Olufsen Beoplay Portal 22,000Hz

High frequency response measures if and how well a particular audio component reproduces high audible frequencies and if it makes any changes to the signal on the way through. Sennheiser HD 450BT's highest frequency is at 22,000Hz, the higher the high-frequency response, the clearer and crispier the treble.

Bang & Olufsen Beoplay Portal's highest frequency is at 22,000Hz, this means that both devices produce equal treble

Sound Pressure Level

Sennheiser HD 450BT 108dB/mW
Bang & Olufsen Beoplay Portal 95dB/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 450BT's measurement is 108dB/mW. Devices with a higher sound pressure level are generally louder when supplied with any given audio source.

Bang & Olufsen Beoplay Portal 40mm

The driver unit is the component that produces sound in the device, its size dictates the loudness of the headphone. Sennheiser HD 450BT driver unit is 32mm in diameter, bigger drivers are more powerful and can produce better bass.

Bang & Olufsen Beoplay Portal driver unit is 40mm in diameter, making them have a larger driver unit than that of Sennheiser HD 450BT 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

Sennheiser HD 450BT 18Ohms
Bang & Olufsen Beoplay Portal 24Ohms

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 wire is measured in ohms. Sennheiser HD 450BT's impedance is 18Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.

Bang & Olufsen Beoplay Portal's impedance is 24Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.

Has A Neodymium Magnet

Sennheiser HD 450BT
Bang & Olufsen Beoplay Portal

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 Bang & Olufsen Beoplay Portal have this type of magnet.
