“The Grado’s presentation was extremely easy to live with and comfortably communicative. It didn’t ram feisty music in my face but maintained it’s lively character. For that reason alone, the Grado will probably gel in a great many systems. And as it only costs $180, yet holds its head up in more expensive company, its a definite Best Buy.”

-HI-FI CHOICE, Alan Sircom

Red1 & Blue1
The newly redesigned Blue1 and Red1 have had their coil design reconfigured, and the effective moving mass of their generating system has been reduced by 17%. The Blue1 and Red1 models use a four piece OTL cantilever technology, standard oxygen free wire in the coils and Grado’s specially designed elliptical diamond mounted on a brass bushing. The Red1 model is selected from the Blue1 production run and meets higher test specifications. Approximately 10% of the production run will meet these standards and become Red1 models.
