I just got mine yesterday and have been listening to it here in the office with my monster turbin pro coppers... The headphones have a really good low end - never had issues with bass. I listen with my ipod touch and find that when I have the volume leveling on, sometimes its just a tad light volume wise... The E5 has definitely taken care of that issue - plenty of volume with leveling on. When I put the bass boost on, almost too much bass...
The real reason I got the E5 was for running. I've been on an odysee to find good running headphones. The Bose E1 and E2's are good sounding and stay in my ears - issue is that since they aren't "in" my ears, the bass lacks and there isn't enough volume. I think the E5 will help me with that and give me the extra boost I need... We will see. 8 miles tomorrow. With the Coppers, I'm really not noticing a difference in the sound, but they are really good IEMs so I would have surprised had I noticed anything... I just got earmolds done for custom sleeves for the coppers through ACS. I'm going to try running with the coppers, but the bang of my foot on the pavement will probably still be too annoying to work...
