*** REVISED: I'm sending the q-jays back ***
After an hour of listening I was impressed by the clarity and strength of the bass with the q-jays, and I wrote a positive review. Later in the day I listened to two very densely produced pieces of music that I love -- Brian Eno's "Burning Airlines" (back when his own work was glam and interesting, before he started cranking out art school muzak) and Catherine Wheel's "Heal". They sounded AWFUL on the q-jays. Midrange and high frequency instruments all blurred together into mush, overwhelmed by the low frequency ones.
With the Etymotics, every instrument in Eno's kitchen sink of sound is distinct. Each time Rob Dickinson yodels the chorus, "it's how high you are and the time it takes to heal," it's the way his voice cracks that makes it heartbreaking. You don't hear it with the q-jays. They completely obscure the breathiness in his voice, which is a sin.
So the q-jays are going back. (Thank goodness headroom.com lets you return them) The SE530s are more expensive and big, but they have a 2' cable plus they would give me the strength and clarity of the q-jays bass without giving up the airiness and separation of the ER4s at the high end. I have to go to Brookstone and listen to them again...
I'm also considering the M-Audio IE40s (UE triple.fi's, clear rather than teal, sold in music stores). They're more uncolored and revealing, supposedly -- closer to studio monitors, which is what I use at home (KRK VXT6's). I'll have to cut the cable to 2' and solder a plug onto it, but at least the cable is replaceable so I won't be doing permanent damage to them. Anybody have these? If you hang them inside your shirt, do the memory wire ear loops look freakish, or do they lay flat pretty well?
The q-jays sounded great playing reggae. If all you listen to is bass heavy music, you might really like them for the price. But they're not for me.
