I love the E series. I'm using E935. Just got it after years of using E855, which they no longer make.
I've also tried and used a number of others with pretty good results, but always return to the Sennheisers. They have almost zero handling noise and very little if any e.q. is necessary.
I can see where one might get high-end feedback if you apply the "traditional" V-curve e.q. that is considered necessary for SM58s and many of its imitators. Just set e.q. flat, and then adjust in very small amounts to suit your voice, if necessary.
E935 is a little on the pricey end, but 835 is more affordable and close in performance.
