Help! Which earphone should I upgrade to from SoundMagic ES 18?

Hi,
I usually watch videos on laptop and listen to songs on mobile. I had Sound Magic ES18 which is broken. I cant find warranty centre for it. Now I am searching for next IEM. Please suggest the best IEM below rs 1000. I dont like much bass. Is the double price of PL21 over es18 justified? Which one should I buy? Suggest some IEMs, preferably with warranty and good noise isolation.

Thanks
