Earpiece Issues (searched)

Hey everyone, I just recently bought a Storm and I'm addicted to it. It's almost stupid how much I've been playing with it since I got it. Anyways, the only complaint that I have with it is the call quality on my end. Whenever I call anyone it sounds muffled through the earpiece, and it sounds like it should be louder. I've searched the forums and tried the treble and bass enhancements. Also, from what I've gathered not everyone is unsatisfied with the earpiece. I'm coming from an LG that had pretty good quality, so I don't know if I was just spoiled or something to that effect. I guess I'm just wondering if anyone could have a clearer answer than what I found while searching. Thanks in advance

p.s. Whenever I call my voicemail it's really clear and loud, but not in actual calls (I read some other people had that issue in a couple threads as well) so would that be network issues? (Verizon)
