I've had good experiences with Grado Labs. When I had a short in my SR-80s, they fixed it in a timely fashion for a reasonable fee. Later, when one of its gimbals broke, they sent me a free one that I was able to install myself. I still used my 80s even after I invested in the lightweight, audiophile GS-1000. I use it every day because I like its lively open sound, rather than the veiled sound of other headsets I've tried. I like 'phones that are light enough that I can wear them for hours. I've found the Grado company friendly to deal with.
