Product Description

 
The HDC 451 NoiseGard mobile set are open stereo headphones with active noise compensation for mobile applications.

The headphones terminate in a standard 0.125-inch miniplug for portable audio systems, plus a 0.25-inch adapter is provided for connecting to home stereo systems and a 2x-mono adapter for airline audio and some other devices.
