1) It is a full range single diaphragm planar magnetic design. Due to the nature of the driver design and due to the damping material we have used, there is very little leakage outward. The sound level drops by 60dB by the time it reaches a meter outside the ear!
2) The geometry of driver housing along with the ear tip and damping material blocks a lot of ambient sound and provides reasonable passive isolation. Yes, you will hear gunshots from the outside. Light-sabers are inaudible.
3) Open design on IEMs allows comfortable and long listening sessions without fatigue. The open and light weight design along with incredible imaging, clarity and sound transparency of our earphones would make you forget that you are even wearing them.
4) The LCD-i3 is more like an LCD4 put through a shrink-ray, but much, much easier to drive - the impedance will be around 20-25 ohms. All of our in-ears can be driven directly by portable devices.
5) There is an audible advantage in coherency and clarity by using a single planar driver instead of dynamic voice coil divers or multiple drivers, like balanced armatures.
6) Planar drivers helped us achieve a very good bass extension down to 10Hz and also helped us get a great treble extension that is quite uncommon in IEMs. When you hear them, you 'll realize no one has ever designed an in-ear with the overall coherency and bass response of the Audeze products. We are talking ruler-flat from 900Hz down to 10Hz. And the widest soundstage of all the in ears we have heard.
7) No, we don't expect everyone to love them.
8) All iSINE and LCD-i3s are the same size. They differ in driver design, diaphragm materials, and finishes. We'll have more info on the LCD-i3 in a few weeks.
9) By including the Lightning cable and having an affordable $399 price point, we are hoping to attract new people to the audiophile community. So we look at the iSINE 10 & 20 as the "next step up" for many customers; not a step down from the LCD series. iSine10 and 20 can stand on their own against most in-ears in the market over $1K easily.
As one Audiophile reviewer commented at IFA after listening to them for the first time..."It sounds like the LCD2 when I heard it the first time"
The iSine's sound like no other in-ears. They are very different.
