Hi GX ! Hey DL !
DL, it's just poor sound quality - a little muffled, not crisp and clear like my cheapo $20 set. Kind of like I have a facecloth between the earphone and my ear. I've experienced this with other headsets as well. In fact, it's been my experience that the cheap headsets often seem to have the best sound quality. I just get tired of replacing them every six months, so I decided to try this more expensive set.
BTW, I checked my ears. No facecloths.
