I think Grado did a very good job on the new GS1000e. I find the treble very smooth and detailed without any kind of sibilance or graininess. Cymbals actually sound realistic and legible on this headphone without any kind of irritation factor. The midrange is natural and spacious. Electric guitars sound really good and it does vocals pretty well too. Not too forward and peaky like RS1i and not laid back or thick like the PS500. Bass isn't quite as big and solid as the PS1000 but integrates well with the music and does pick up some impact with more hours on the drivers. I have enjoyed my pair a lot and find them one of the most well balanced Grado headphones I have ever owned. Give them a listen if you get the chance and you may be surprised.

The good thing about getting the 60e for example vs ms1 or 80e is that the factor where it hass slightly less bass make them work with flats more.
