JBL J33i not supported by Sony Xperia Ray (ST18a)

Hello. Am currently facing an issue with my Xperia Ray ST18a, whereby it is detecting old earphones, but not my JBL J33i, giving the message "Accessory not supported" when I plugin in the earphone. I've seen that my older earphones have only 2 black stripes on the jack, while the Sony one itself has 3, and the J33i has 3 as well but white ones. The J33i however plays on a SGS5. Any one knows why the ST18a is not identifying this earphone :confused:
Thanks...
