I am unaware of iems that can offer the boom you are looking for. Plus, that wouldn't really render their sound very "natural" as desired by you. Unless you are willing to pay a hefty sum for having earphones shipped into India, I suggest you check out the soundmagic PL30s and E30s. Soundmagic...

Personally, I am not much of an advocate for burning-in a pair of earphones and feel the perceived change in sound is just that- perceived or psychological. While the drivers will certainly open up and become able to make greater excursions after burning in, I think that'll only make things...

for iems that are marketed as bass giants (Twinwoofers?!), the entire lower end of the spectrum is extremely poor and the bass lack any punch and pace whatsoever. The overall sound is quite boring which is particularly disappointing considering that they are far from being neutral and flat...

  Okay so even though i'm not an audiophile in the sense that I don't necessarily look for the most neutral, flat IEMs, I do want to enjoy the music I listen to (mainly rock/ classic rock) the best I can and have spent many hundreds of dollars over the last 3 years trying out different IEMs...
