That is exactly what I am finding....my pitch gets off with the in ears in. Instruments sound great but I can't live with the pitch problems. I'll know more once we try some practice with the whole system. With the over ear headphones I don't have the pitch issues but it would look goofy using them live. Thanks for all the input on this....I had just seen so many of the pro acts use the in ears so I thought I was missing out on something.
