Over the years, Sennheiser has built a solid reputation with its high-performance audio products ranging from Loudspeakers to headphones. As a matter of fact, the company's name holds quite a grip for audiophiles around the world. In an effort to manufacture once again the best headphones, Sennheiser is bringing an update to the critically acclaimed Orpheus HE90 that debuted back over two decades ago.

The German company first created the Orpheus HE90 back in 1991, which was then branded as the best pair of headphones available on the face of the planet. However, it cost a whopping US$16,000 and only 300 units of it were made. In fact, even buying a pair today would at least double its price.

Fast forward to today and Sennheiser updates the Orpheus, and this time it would cost interest buyers about US$55,000, which makes it more than triple the price of its original counterpart. According to reports, the new Orpheus Headphones have been in development for more than 10 years.

According to Sennheiser, the new Orpheus features an audio range from 8 Hz to more than 100 khz, as well as the lowest distortion ever measured in a sound reproduction system at 0.1 per cent at 1 kHz, 100 dB SPL. It's also the first electrostatic headphones with Cool Class A MOSFET high voltage amplifier that is integrated into its ear cups, thereby eliminating the capacitive reactance of the cable. Furthermore, it comes with a 2.4-micrometer platinum-vaporised diaphragm, gold-vaporized ceramic electrodes, and an amplifier that is encased in glass and a solid block of Carrara marble.

The new Orpheus headphones feature eight digital-to-analog converters to coax the most exquisite sound even to anyone's low-quality music tracks through its digital amplification.

Reports suggest that while the Orpheus from 1991 came in limited production, Sennheiser will offer the newest version "from next year onwards." Its production however, will only be limited to 250 produced per year.
