The initial RS1e headphone (which I subsequently call the "original RS1e" in my discussion below) sounded markedly different, generally regarded as worse, than the RS1i, RS2, or any of the other Grado headphones. It had poorer bass and poor treble, with the treble dropping off at about 3 kHz.
This plot combines two plots from innerfidelity.com. The solid red and blue lines are the frequency response of the right and left earpiece of an original RS1e; the dotted line is a tracing I added of the frequency response of the RS1 (original). You can see the dropoff in the treble of the RS1e.
Spectral response of original RS1e (red and blue) vs. RS1 (dotted black line) shows poorer bass and severe treble attenuation of the RS1e above 3 KHz.
The RS1e moved from the 44 mm driver of the RS1i and RS1 to the 50 mm driver also used by the PS1000e and GS1000e. It was found that the original RS1e had the driver extending above the rim of the wood cup toward the ear. Pictures from
@Oracle compare this "protrusion" of the original RS1e to the flatter, non-protruding edge of the RS1e made today.
Original RS1e - driver protrudes above edge of wood.
Current version of RS1e - driver does NOT protrude above edge of wood as much.
The protrusion arose because the driver itself was moved closer to the ear in the original RS1e. This can decrease soundstage and treble. The more recent RS1e, which is regarded as better sounding than the original RS1e, moves the drivers a bit further from the ear; hence, less protrusion and better soundstage and treble.
Rather recently, Grado changed the color of the RS1e headband from black to brown. Though the timing is not exact, it seems that if you buy an RS1e with a BROWN headband, you can be relatively sure of having the better non-protruding version. If you get the black headband version, it will likely have the protruding drivers.
Here are images of the RS1e original and RS1e current from @Oracle that correspond with the two detailed pictures of the driver/earpiece above:
"Original" RS1e - black headband; protruding drivers (per picture two above)
"Current" RS1e, with brown headband and non-protruding drivers.
Another observation is that when the same L bowl pad as used on the RS1 and RS1i with 44 mm drivers is put on the RS1e with 50 mm drivers, the bowl pad is stretched, becoming flatter and harder, and moving the driver even closer to the ear. There were also complaints of the driver actually touching the ear in the original RS1e headphone.

I do not yet have an RS1e headphone. I HAVE compared an original RS1e to both my RS1i and my RS2i at a Grado dealer and found it to sound the poorest of the three. When I get an RS1e, it will be the one with brown band and non-protruding drivers.
