Sure - it`s actually Ostry, not Osty. It was my typo above and I`ve fixed it.
They suddenly appeared here in Tokyo and nobody seems to know much about them. They are from Ostry, the chinese IEM maker, but as far as I know they are not included with their IEMs. They are marketed as sibilance-controlling tips, and come in three strengths, called OS100 (blue), OS200(red) and OS300(strongest, black). They look a lot like Spinfits (translucent white silicon with colored insert) but fit nothing like them. There`s no flexible joint, the sound tube is completely rigid -cannot collapse because there is a metal ring inside, and there is a metal mesh in there too. I bought all 9 variations (3 strengths x 3 sizes) I`ve been testing the M size OS200s all morning on both my Dunu DN2K and Fitear Parterre and the results are quite interesting, and kind of confusing.
First off, I am getting a perfect, effortless seal with both ears, with the M size. They don`t insert as far as Spinfits, but the quality of silicon is such that the seal, for me, is simply perfect.
Second, for some reason I am hearing a definite increase in detail. Assuming the metal mesh is there to block certain frequencies (associated with sibilance), I was expecting a loss of detail.
Third, with the Dunu DN2K, I am losing significant bass frequencies, the low end is rolling right off. I think this is due to the excellent seal and grip of the Ostry tip, its rigid nature, and the weight of the DN2K: The drivers are simply being held at an un-optimized angle by my outer ear canal shape. If I use my hands to change the angle, the bass returns as clear as ever. The DN2K do include all those little silicon add-ons to hold it in place, so I am sure I could align them perfectly, but it`s too much of PITA for me to do that, because the DN2K with Spinfits is perfection.
With the Parterre, there is no loss of bass, I assume because the rigid over-ear cable is holding the drivers where they need to be.
It is still very early stage of testing these; I will be taking them out today with both IEMs to do some shopping so it`ll put more real-world challenges on them.
They really are beautifully made. I didn`t think silicon tips could get more complex but Ostry managed to do it.
How does it compares to spin fit in other earphones? What i heard that Spinfit has some problem with Dunu DN2k?
