The phones are smaller than I expected, and weigh less than Monster Turbine.
Just tried them without burning in. Surprisingly, coming from a Sony product, the bass is noticeably weaker than Turbine. And there's more hiss than both RE0 and Turbine, using my Sansa Fuze.
Have to try more after burn-in. But I just realized that I got huge ear canals - have to use the second largest tips.
