The Items works like a charm. I need them to perform a modding on my Sony Eartips so I can use them on my IE800 MMCX (fake) since I do not possess the real IE800, I can't vouch compatibility. But after this mod.... Oh man... It brings tear to my eyes. The voice is very very flat, Vocal is controlled and falls back, bass was fast, agile, no longer burst, sound staging feels bigger, less centered. If you gave similar stuff with Tesla Driver, and need Flat profile, this is something you need to drive the bass lower.
please note that if the item is shiped to UK, you will be charged extra 50% of the value as customs fee. a good deal but fees too high. also the pad has only 4 sizes on L L S S. no medium.
