Tech stuff
Two key features from Sennheiser Hi-fi ensure good sound

– Adaptive baffle damping guarantees consistently good bass.
– The patented Duofol diaphragms prevent unwanted
resonances, guaranteeing crisp, crystal-clear sound.

Sennheiser pioneered consumer noise-reduction headphones
over 20 years ago and have unparalleled expertise in this technology

– NoiseGard noise-cancellation technology actively neutralises
unwanted noise: a tiny microphone mounted on the outside of
the headphone picks up ambient noise, a processor calculates
and superimposes the relevant phase inverted sound.

The result: the two acoustic signals cancel each other out and
the unwanted noise no longer reaches the user’s ear.

The new NoiseGard 2.0 uses optimised circuitry design and
even more efficient processors. It also uses better quality
microphones, which enable more sophisticated pick-up of
unwanted noise. Specially developed filter algorithms enable
improved active noise compensation of up to 90% (23 dB).
