Sound Quality

Has Active Noise Cancellation (Anc)

Sennheiser HD 450BT

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 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 zero 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.

Has Passive Noise Reduction

Sennheiser HD 450BT

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.

Lowest Frequency

Sennheiser HD 450BT 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 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.

Highest Frequency

Sennheiser HD 450BT 22,000Hz

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

Sound Pressure Level

Sennheiser HD 450BT 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 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 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 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.


Sennheiser HD 450BT 18Ohms

Impedance is 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 450BT's impedance is 18Ohms, the lower the impedance, the easier it is to get higher volume and requires less power.


Battery Life

Sennheiser HD 450BT 30hours

If your headphones play wirelessly, cancel ambient noise, or enhance your listening experience with active features, their battery life will reduce over time.
