It's not just you, the reports I've read are that EA500LM is too bight, even some reviewers that praised it said stuff like "best suited for mid volume listening" which is code for too bright.I got a set recently and I have to agree, it's not that great (to my ears)
I like the treble but the low end is a bit disappointing, to my ears it sounds warm but without much substance and there is no punch or rumble. Other people reports though are fairly positive so not sure if it's just my ears.
For many reasons I feel there are many reviewers who are the least decerning.
