that's a big statement , as the eq-5 were selling for 200-250$
i used to own a pair of eq-5 and i really liked them , although they were a little 'hot' in the highs - which was hat led me to sell them
i will try tomorrow RE-400 , i am intrigued even more to see how these sound
I use the RE-400 on a daily 20 mile cycle commute, through towns, villages and windswept country roads. I find it isolates better than any other dynamic I've used, and is as good as some BAs. They're also very comfortable.
I've been comparing them to the eq-5 recently, and far prefer the re-400, in all respects.
