Sound Quality

Has Active Noise Cancellation (Anc)

Sennheiser HD 450BT
Bose QuietComfort Ultra

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 hence "diluting" the 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.

Bose QuietComfort Ultra 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
Bose QuietComfort Ultra

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 Bose QuietComfort Ultra isolates you from ambient noise instead of actively using technology to cancel it out.

Lowest Frequency

Sennheiser HD 450BT 18Hz
Bose QuietComfort Ultra 20Hz

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 450BT's lowest frequency is at 18Hz, the lower the low-frequency response, the stronger and juicier the bass.

Bose QuietComfort Ultra's lowest frequency is at 20Hz, this means that Bose QuietComfort Ultra got a juicier bass than the Sennheiser HD 450BT

Highest Frequency

Sennheiser HD 450BT 22,000Hz

High frequency response measures if and how well a particular audio device 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.

Bose QuietComfort Ultra's highest frequency is at 20,000Hz, this means that Sennheiser HD 450BT got a clearer and crispier treble than the Bose QuietComfort Ultra

Sound Pressure Level

Sennheiser HD 450BT 108dB/mW
Bose QuietComfort Ultra

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.

Driver Unit Size

Sennheiser HD 450BT 32mm

The driver unit is basically a mini speaker 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.

Bose QuietComfort Ultra driver unit is 35mm in diameter, making them have a larger driver unit than that of Sennheiser HD 450BT by 3mm , 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 can generate louder sound, but this does not mean that they produce better sound.

Impedance

Sennheiser HD 450BT 18Ohms
Bose QuietComfort Ultra 32Ohms

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.

Bose QuietComfort Ultra's impedance is 32Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
