If the AE2 sounds anything like the Triport, it's nothing special but nothing terrible, either. I think your experience is about what's to be expected.
Big bass doesn't really equate objectively with sound quality, though; most young people prefer it (see: the Beats) and most audiophiles dislike it because people lose treble hearing first and so increased treble sounds like increased detail to the older, deafer audiophile audience. So a lot of the best headphones are treble heavy and a lot of the more popular ones are bass heavy...
That said: if you like bigger bass, go after it. This kind of purchase is best made subjectively. But you might find a distorted frequency curve is muddy or fatiguing after a while even if it sounds great at first.
If you look here the IE2 has a ton of bass, just a whole lot of it:

The red line (Etymotics) is a very close approximation of diffuse field equalization, which is an approximation of the subjective frequency response of speakers from a normal listening distance. So in essence it's a simulation of perfect speakers. And the Bose has WAY more bass.
The AE2, which most reviews don't praise as highly as the in ears, has a much flatter curve (still quite bass heavy):

So it's more technically accurate. Maybe subjectively worse.
If you already have a portable option with the IE2s, consider returning the headphones and going for the Sennheiser 518. I've never heard it, but it's only $100 and the biggest complaint I've read is that its bass is too strong (probably still weaker than the Bose IEMs) and it's apparently much better than the 515, which is excellent, and if it's anything like a bassier 595 it's probably just awesome.
