My ears fit perfectly inside the earpads. I love the Momentums, but I do think the bass can get boomy (not uncontrolled) at times with certain songs (with an amp the likelihood of this goes down).
I can totally understand if someone does not like the signature.
You should try the DT1350...it's not as comfortable, but the bass might be more to your liking,
Not really in the market for portable cans. They were there in the shop so I tried them on. DT1350 sounds better to my ears though. Shame they're not so comfortable.
