    flinkenick's 17 Flagship IEM Shootout Thread (and general high-end portable audio discussion)

    Dryer is better for eject excesive moisture from sound tube, damper and driver. But for UV light, i can not guarantee. At hearing aid UV light sterilizing but CIEM it may cause deformotion. Because UV light changes polimers moleculer structure so a fast aging occur. edit: I can say that for...

    No, focus on connector. I mean the 4 pin connector used before the patent date. So there is no protection on connector. (Still not sure :) )

    flinkenick's 17 Flagship IEM Shootout Thread (and general high-end portable audio discussion)

    For measurements; Here are some interesting pages from the Colloms book about assessment of sound. It is directed at speakers, but still applicable to iems. The main topic is what part can be attributed to measurements, and what part to objective evaluation, and how to combine both. The next set...

    Hi; Your understanding of mechanical side is so rudimentary to think logically. But I want to add some words from my point of view. At dynamic system modelling, there is 3 types of elements; Mass, spirng and damper.(all ideal case everthing are rigid objects) At damping case behaviour a bit...

    Introducing Lotoo PAW Gold

    Did you try by-pass the caps, just short circuit? If there is no shift on base voltage, it will be good.

    Sony announces the "Just ear" brand of custom IEMs

    Haha, I should have known   But my opinion is different from others. I am an old school boy. To my opinion old machines( generaly) work better than todays sophisticated technological machines. For example, old coal fired powerplants( as I saw from my technical inspection) are working more...

    Home-Made IEMs

    The masking is very and very very improtant phenomenon to my opinion, todays sound industry mostly based on it(recordings, theatre effects(dolby digital i.e.), some concert effects and usage of compressor(as I know, not sure completely) etc.). Therefore, in that area, it also important. Too...

    Home-Made IEMs

    Exactly, The worse thing is, sometimes, it destroys the stable operation at bass and mid region, if it occurs someone extinguish the fire, he will be a hero.

    Home-Made IEMs

    The CI(sonion 2000 series similarly) has very much bass at mid-bass region especially. A intervention needed sometimes but they are really powerful. Very old but good.
