I've had Sony MDR-7506s for about 7 years now, two cup replacements but otherwise going strong. I've also had my Audio Technica ATH-M50 for a solid 12 years, one cup replacement, sound great and work perfectly. I have basically worn one of those two pairs of headphones every single day at work since I bought them; I guess I've just had good luck.
