You are not alone on this observation. I can normally tell the difference as I can hear some minor compression with my EPH-100 on 128kbps, but its not terribly distracting. Put on these new Pistons and man... every little artifact is just front and center. Overall, the pistons are a solid $25 headset with mic. They aren't game changing like the Sony MH1C was when it was under $30, but they are more than competent for their pricetag.
