Both Sennheiser HD 350BT and Sennheiser HD 450BT have stereo speakers Active noise cancellation uses more advanced technology to reduce unwanted ambient sounds.
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 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.
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 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 Sennheiser HD 350BT isolates you from ambient noise instead of actively using technology to cancel it out. 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 driver unit is 32mm in diameter, making both devices similar in how loud their sound gets , many people have a misconception 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 deliver better sound. 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. Sennheiser HD 350BT's impedance is 32Ohms. The impedance of earbuds is the electrical resistance of the driver unit present on the inside.
