No, not in the context of IEMs at large, but juxtaposed with the SM3 I found that the EQ-5 was a skosh brighter. More treble presence does not necessarily make it sonically brighter, it is the sound signature as a whole that I found brighter than that of the SM3 but not by a large margin. Everyone hears a bit differently though, so take my opinions with a grain of salt.
Yes, I understand. I would say that SM3 is warmer than EQ-5. That says about the same thing. Neither is overly warm and neither is overly bright.
