Are you sure you're getting a good seal with whatever ear tips you're using? I find that the bass on the IE8 is too much for me, and still a bit much more than what I'd like at the minimum setting; it's one thing for a subjective requirement to say "not enough" and another to say of it "barely feel and hear it."
In any case, have you tried other IEMs, preferably bassy ones? Because you won't really "feel" bass in personal audio, especially IEMs, compared to speakers let alone a subwoofer. With my Wharfedale Pacific Pi10 standmounts (driven by a NAD 304) I can sit around 2m away and still feel the bass drum on my chest many rock tracks; and in my car, while my Polk 10in sub is in a compact sealed box, adjusting the subwoofer output gain on my receiver's processor gets that thing setting off car alarms when I drive through a parking building. You won't get the chest-thumping sensation in personal audio because to begin with the air that the transducers will move will in no way hit your chest, and in case you do feel it especially with IEMs, it usually causes a headache (IEMs can seal your ears so well that the pressurized air has no way to go, and then each successive note further presses against that air, and hten your ear drums get torn up like a virtuoso drummer on a worn out snare drum).
What do you mean? You're supposed to get your money back if you return the product, you'll just pay return shipping and restocking fees - even if you file a complaint that it's counterfeit the only way to get out of paying the return shipping is if the seller decides to just let you keep it after filing the PayPal dispute. Either way people who don't have any audio dealers in their area absorb such fees for demoing them at home (or wherever they'll use them, in the case of portable gear) in lieu of driving 50miles or more to the nearest hi-fi store.
