I have been born with big lugs, they have advantages and dis-advantages. At school there were a burden but as I got older, they became enjoyable, in that I can hear very low frequencies, helicopters miles away, earthquakes a second or so before they hit. you get the idea! Due to having big ears, I usually need to use the biggest seals on any iem's I buy, or get headphones that have big enough cups to fit my ears in, Sennheiser HD598's. So, this is not a slag off but I have been watching this forum for a long time and been reading the reviews from quite a few people but lately those recommendations have fallen very short of what I need. Recently I got a set of Soundmagic PL30 earphones as they are supposed to be good at bass and a great all rounder, well not to me, they have no bass, the mid and treble sound good, just no bass! I got hold of a set of Audiofly AF78's again no bass and no top end either, a set of Shure SE215's are pretty good but again I find the bass lacking a bit, the rest is super clear. A set of Xears XR120 pro's have a decent amount of bass when the right foam tip was used but a bit muddled in the mid and treble, not as clear as the Shures, yet my favorite set of earphones at the moment are my Soundmagic E10's. They lack a bit of treble extension but bass and mid are wonderful, what I am looking for is a set of iem's that can produce the bass of the E10's, the detail and control of the SE215's. My son has a set of "Able Planet" S1210s and the bass is so controlled and extends down sooooo loww! Please help me to stop throwing money away, I need to know what earphones match the sort of thing I am looking for, does anybody have any useful ideas? Help.
