I bought them in January 2007. Very quickly, 3 months afterwards, I noticed a defect with the jack connector (a channel would cut off). So I took the headphones back to the store (in Paris) where they immediately said I probably ripped the cable. One month later, they offered me to have the cable changed by a technician for €90. I told them I was surprised that it wasn't covered by the Grado warranty and asked them to put me in direct contact with the Grado importer in France. Three months later I had no news, so I got in contact with them again and they said Grado "had no cables in stock." So, with no cables after March 2009 the only solution was to let their technician repair it for €90. I refused and demanded they give me my headphones back, which they did, one week later. I noticed that the cable of my headphones had in fact been severed with a cutter where the left and right headphones split. I contacted the Grado importer who confirmed that they had indeed been contacted by the reseller for a spare cable, and they also told me that they didn't offer after-sale service and had forgotten to order the replacement from Grado USA. The result? I payed almost €400 for a pair of headphones and also have pay for the repair. My impression of GRADO as a brand is very poor.
