Do manufacturers honor their express warranties when you purchase from non-authorized dealers? If, for example, you buy a factory-sealed pair of SE530s on ebay and later discover a defect, will Shure stand behind them or tell you to get bent?

Hi, long-time lurker and first-time poster. In a former life, I spent stupid amounts of money on high-end audio...digital separates, tube amps, Avalon speakers, etc. I even had some of those fat interconnects people love to talk about. Anyway, I'm now looking for some good IEMs to mate with...
