Just thought I'd share my most recent experience with Shure. I purchased a pair of second-hand SE535's not too long ago, and upon delivery, they were faulty. One earpiece experienced diminished sound, and there was no visible material clogging the nozzle. Fortunately, the seller provided his original Guitar Center receipt, with which I contacted Shure requesting service under warranty. Being that the warranty was under the original seller's name, I was informed that I shouldn't encounter any problems since the warranty is transferable. I sent the faulty pair back in, and only 4 days later, I received an email notifying me of a brand new replacement unit being dispatched, only they weren't sending me the SE535, but instead, the SE535V! They arrived just minutes ago at my door, and I'm once again enjoying their blissful sound.
Hats off to Shure for their wonderful warranty coverage!
