We have for our son, who owns a Samsung Galaxy Si9000, the Apple apple earbuds bought Apple apple earbuds with remote and mic, as it has problems with the conventional in-ear headphones. Allegedly, these should also be compatible with a Samsung smartphone - in our case it was unfortunately so that the full sound could be heard only when you held the microphone button. Looking for a solution, we are then on these two adapters FiiO LU1 Adapter Cable - Use the iPhone specific headphones on different brands of phone and Fiio LU2 Adapter Cable - use of iPhone specific headphones on different brands of phone encountered. We opted for the LU2 with the angled connector, in the hope that the angled connector has a longer service life when it is stuffed and stored in jacket and trouser pockets. The function test was positive - the sound was full as, the functions for microphone, loud and soft, as expected, but that's for our son not been important. The connector is high-quality and you can check even the "authenticity" to the manufacturer's site using a code.
We are very satisfied and can recommend this adapter fully, if there is incompatibility issues of Apple headphones on a Samsung Galaxy Si9000 smartphone.
