Sennheiser PXC 450 NoiseGard Active Noise-Canceling Headphones
The Sennheiser PXC 450 is a premium around-the-ear travel headphone set featuring Sennheiser’s exclusive NoiseGard 2.0 active noise compensation system, which effectively reduces up to 90% of ambient noise. Adaptive baffle damping and patented Duofol diaphragm technology deliver pristine audio production. The extremely comfortable headphones offer audiophile-grade sound combined with a foldable construction for maximum enjoyment and convenient storage.
NoiseGard 2.0 and TalkThrough Technology
The switchable NoiseGard 2.0 technology reduces ambient noise up to 90%, with active/bypass mode for use as a noise cancelling or closed-back audiophile headphone. The innovative new TalkThrough function allows the user to communicate with neighbors without taking off the headphones. Unwanted background noise, such as the roar of the airplane engines, is filtered out so that only the neighbor’s voice is passed on through the headphones at top quality.
Comfortable headphones offer audiophile-grade sound combined with a foldable construction
Just one AAA battery is all it takes for up to 16 hours of serene enjoyment with NoiseGard 2.0 and TalkThrough technology. The PXC 450 also functions as a passive headset when used without batteries, so audio always works. A simple-to-use volume control is integrated into the headphone.
The Sennheiser HD 280 PRO features rugged construction with user-replaceable parts, including the cable and the earpads. The single-sided, coiled cable has a 3.5mm mini jack and comes with a locking 1/4″ adapter for home or studio stereo equipment, as well as an In-Flight Entertainment adapter for airplanes.
