Well, so far, I have narrowed it down to these two. But without listening to them, I just can't decide which to buy. So I ask you which sounds better? I listen mostly to rock and some techno and at first I was set on the 225s because they are supposed to be the best rock phones.
But,
I then came across the Etys and I very much like the whole isolation thing and the great, detailed sound certainly didn't hurt. I guess my question would have to be: Would the Etys really sound all that bad for the music I listen to? Because I'm leaning toward the ER4s because I tend to listen in noisy environments. Thanks in advance for any help you can give me.

If you tend to listen in noisy environments, there is no contest, the Etys win. I close the doors and windows in my living room before donning my SR225.

Ety's!

Hmm. Looks like my choice just got a little easier. Thanks.
