Until now, the audiophile headphone experience could only begin with Sennheiser’s open back design A design that paved the way for an entire class of precision listening devices. This standard of sound reproduction would go on to surpass hi-fi systems exponentially larger in size and cost with the understanding that listeners would not be isolated from their surroundings. The HD 820 sacrifices neither detail nor sound field thanks to its innovative acoustical systems in a closed, dynamic headphone.
