Meet Sennheiser HE 1
Beauty with a purpose
Sennheiser HE 1’ striking design marries form to function. Its amplifier sits on a housing crafted from glass, and a solid block of Carrara marble. This luxurious natural stone—the type made famous by Michelangelo’s Renaissance sculptures—lends beauty but also prevents structure-borne noise. To create a visually stunning design, control dials are painstakingly crafted to the highest quality. Each dial is milled from a single piece of brass before being plated with chrome. This is music turned into an object.
The relentless pursuit of perfection brings with it a uniqueness. Thus, the Sennheiser HE 1 is the first electrostatic headphone with a Cool Class A MOS-FET high voltage amplifier integrated into the ear cups. Eliminating the capacitive reactance of the cable, delivering an ultra-high impulse fidelity 200% more efficient than any other solution currently available. 2.4-micrometer platinum-vaporised diaphragms are employed as their size was shown by Sennheiser’s research to deliver optimal sound reproduction. Outstanding electrical and acoustical performance is ensured through gold-vaporised ceramic transducers, while 99.9 % silver-plated OFC cables are used for optimal conductivity. To allow you to immerse in the result of all of this are Sennheiser HE 1's ear cups, precision-machined from solid aluminum, featuring handmade ear pads of finest leather and a soft, allergen-free velour/microfibre construction.
Everything but Compromises
The advantages of tube amplifiers and transistor amplifiers— with Sennheiser HE 1 you have them all. Thanks to a patent pending circuit design. Its vacuum tubes connected to the spring-loaded, damped marble housing to prevent structure-borne noise and surrounded by high quality quartz bulbs that protect against air-borne noise this state-of-the-art amplifier delivers ultra-high impulse fidelity at an ultra-low distortion level. For digital to analogue conversion, the amplifier can receive digital signals via optical and coaxial SPDIF inputs or USB input, it also accepts high-resolution PCM and DSD data. Music data is converted to analogue signals using the 8 internal DACs of the ESS SABRE ES9018. Four channels in parallel are used for each stereo side to enhance accuracy and decrease distortion and noise level.
