Yes, I think that the IE800 does have more bass. Next time I go to Hong Kong, I can make a direct comparison. (Edit: Just saw Jame`s post above. That looks right to me.)
I no longer find the IE800 to have too much bass. In particular, I have not used my -1db EQ setting since the Pico Slim arrived. I received a PM from a Head-fier who had also tried the Pico Slim + IE800 combination in Singapore and liked it. He said
The point about reining in the bass is interesting. The Pico Slim certainly does not reduce bass quantity; I have confirmed this on direct comparisons. (It does make the bass impact tighter.) However the slight rebalancing of the IE800 sound using the Pico Slim makes the bass fit in better. So I agree with the quotation above.
That's probably what he means by reign-in. It makes the bass noticeably tighter (more controlled) which I generally see a a big plus. I don't mind having a lot of quantity but I want it to be well controlled and not fart-like ;).... As James says the IE800 has quite a bit more bass quantity in the sub bass region in comparison to the Fit Ear 334. That doesn't sound so bad IMO. I generally don't have a problem with deep sub bass as long as it doesn't overshadow the mids and treble.
