I finally decided myself to bought the Grado SR60i after all the great comments I read about them. I already have a few pairs of good headphones, but I wanted to try this "legendary" model.
I have to admit they are good and fun sounding headphones, especially in the midrange and the bass. But they are not the best in this price range for me : the one to beat is still the Shure SRH440, which is more balanced and refined than the SR60i.
The SR60i have well enough bass for me, but the problem is the treble extension. It's funny because I've read a lot of comments stating that Grado headphones can have too much treble. Huh? I really like the SR60i but they don't have enough treble sparkle for me (unlike the SRH440). It's not me having some hearing impairments : I can hear up to 16kHz and clearly at 15kHz.
I think the problem may be the S-cushion "comfy" pads. When I press the headphones onto my ears, I have more treble presence and extension. Maybe the L-cushion "bowl" pads could wake up the treble? Or maybe the mod of cutting a quarter hole in the pad can reveal more treble?
Any suggestions to reveal the treble on the SR60i?
