Received my MTPG from amazon today ( authorized dealer ) and i am very disappointed. The only other high end earphones i've had are radius DDMs and they sounded far superior. I cannot get a proper seal with any of the tips, which includes super tips and sony hybrids. They sound very tinny and bass-less, comparable to stock apple buds with eartips. Could this be a tip issue or may i have received a faulty pair? I have tried over a dozen of the tips Monster included and none of them seem to work !
