I do quite a lot of interview work.

I find two CM4 spaced about 8 inches apart on a little K&M bar, just pointing a tiny bit outward, gives me BBC Radio 4 type sound no matter where they move their head. Single mic would not cut it I feel.

Same technique on various Spots in Orchestra recording too.

Love the CM4 more every day!
