About this item ZEXPro is the first Electrostatic & Dynamic & Balanced Armature hybrid earphone of KZ. Three kinds of high-performance, sound generating units are integrated, and the electrostatic field formed by the change of the two electrode plates makes the sound more uniform and the quality consistency is more stable. 20kHz high frequency even better performance than Balanced Armature,benefit from the high density sounds and Hi-Res audio performance of the electrostatic,ZEX Pro has more details and greatly improved high-frequency ductility. Wide sound field satisfies the sense of hearing The aviation-grade zinc alloy radium carving surface cover is matched with the imported skin-friendly resin cavity. Delicate metal texture and stylish streamlined beauty coexist. The 2PIN interface used by ZEXPro can freely assemble and upgrade the wire. The structural design has been improved, and the limit slot protection design has been added, which effectively protects the pins from breaking and prolongs the number of plug-ins and the service life of the interface. The excellent ergonomic design fits the cochlea and accurately matches the ear structure of the mainstream people, ensuring that the headset provides a comfortable, safe fit and effective noise isolation.

A drop-dead gorgeous Italian tube amplifier for electrostatic headphones. Okay, you now have my undivided attention!
Equipped with unique features and state-of-the-art technology these headphones transform music from something you listen to, into something you live in. 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.
The operation of various electrostatic machines is described.
Electrostatic Motor: 3D printed electrostatic motor Goal: No ball bearings, easy mounting, new different design with low power requirements Requires: 1x 3mm screw about 10mm long e.g. unused screw from old PC hardware 1x 50 mm wire ~0.5-1mm e.g. paperclip 1x alumin…

This year at CES -- as always -- there's been waves and waves of new technology. Not everything of interest is always white hot, though. We're talking about the above pair of headphones -- the Orpheus HE90 from Sennheiser. Those in the know will be somewhat familiar with these headphones, as they made their initial debut in 1991. Yeah, 1991. The limited run of 300 pairs has secured these exclusive cans a special place in audio folklore. The electrostatic headphones combined with a companion all-valve amp are what many consider to be a reference point in hi-fi. As a small example, most consumer headphones offer a frequency response somewhere in the region of 60 - 20,000 Hz. The Orpheus offer from 7 - 100,000 -- we're guessing even some bats could struggle to hear frequencies that high. Of course, audio can't truly be measured in pure numbers and specifications. There's some clever custom technology, such as the dual-electrodes the HE90 have between the diaphragm that is the cornerstone of the push-pull principle, that go a long way to helping these cans use to produce their sound. And what about that sound? Well, we were lucky enough to get some quality time with them, and what can we say. The first thing that hits you is the clarity. Bright, plucky, light audio dances its way from the large and comfortable ear-cups. In fact, these things are so comfortable that you could wear them for long, long periods of time and we'd wager you remain comfortable, without any ear fatigue. The build is wonderful, and the leather cushions on the cups changes to a cloth material on the part that rests on your skin. The size of the ear-cups is also a major factor in the overall luxury of the Orpheus, and the ovular design means your ears sit snuggly inside, while they dish out the delicious audio. We'd normally tell you about price and availability at this point, but in the case of the HE 90s, it's a bit of a misnomer. These were priced in the double-thousands of dollars at launch, and with only 300 pairs produced, that price will have increased somewhat over time. If you can find some though, even if it's at a trade show, we recommend you take the opportunity to have a listen. Billy Steele contributed to this report.
