The large ring represents the general size of a standard electrostatic earphone drive unit, and the small ring represents the general size of the KSE1500 drive unit, which is only 1/8 to 1/11 of the standard electrostatic earphone drive unit.
Electrostatic technology has been used for a long time, but the products are mainly large diaphragm floor-standing speakers or full-size on-ear headphones, most of which have no effect of isolating ambient noise.
The amplifiers of these systems usually need to be connected to an AC power source (wall) and are not suitable for mobile use.
The KSE1500 is portable, lightweight, and soundproof, and its features will maximize its utility in today's digital world, such as DACs and high-quality DSPs.
Unparalleled audio clarity and precise detail, with the fastest and most accurate transient response on the market
The main advantage of an electrostatic drive unit is that it has almost no weight diaphragm. It can be said that there may be no scale in the world that is sensitive enough to weigh the weight of the KSE1500 diaphragm. Mathematically, the diaphragm weight is about 0.0002 grams, while the one dollar bill has a weight of 1 gram, which is 5000 times that of the diaphragm. Therefore, it moves much faster than the diaphragm in a conventional moving coil or a balanced armature drive unit.
Imagine what it feels like to quickly shake the bowling in your hand.
Then think about how simple it is to shake the table tennis. The lighter the weight, the faster the shaking.
Similarly, an electrostatic diaphragm with almost no weight vibrates very quickly, and a single such diaphragm reproduces the sound quality of the original audio with unparalleled precision.
A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe. A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.
Although the word flange generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as 'flanges':
There are many different flange standards to be found worldwide. To allow easy functionality and interchangeability, these are designed to have standardised dimensions. Common world standards include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped publishing B16.5 in 1996, and the standard is ASME B16.5
