I have since November 2009. Grado Labs, Brand New-York, is best known in the Anglo-Saxon and the SR60 has received several awards. Its construction is not exceptional but it is still reliable. I can keep this headphone more than 2 hours without discomfort. As the sound is balance, space and harmony. I quite agree with the previous opinions. Good definition, no more aggressive bass found on many headphones as some Sony MDR.La sound is really nice. The value is good: 130,00 € in France so that many European brands can get dressed!
