There is... I'm afraid...
The Ety ER6i's, which I've had for a day so far, sound, in every way much better than the EX71's. More transparent, greater detail to the recording, tighter bass...
BUT! If you've never heard the ER6i's then you would never know. I've had my EX71's for 6 months now... and for that period of time I loved them. People who aren't into earphones say, "Hey, aren't those the 'phones that make the sound go in your head?" And I respond with, yes, they do just that....
The trouble is, if you buy the EX71's you'll know that there's a better pair out there...
There's always a bigger fish... (the Ultimate Ears UE10's come to mind)
