Does Micromax Canvas Fire A093 follow CTIA or OMTP standard for audio jack??

Most of the earphones of some brands like lenovo, samsung, sony, skullcandy etc. are not compatible with my canvas A093(Fire-yeah its history). So i figured that(not confirmed tho) the jack must be an OMTP standardized one. Is it so??? If it is OMTP, which earphones can i use with it, like those of ATH/Brainwavz/Sennheiser. HAAALP

I think you have OMTP standard because I have mobile A092 and i haveĀ  problems too
