Great for Churches!
Our pastor had grown increasing annoyed by the way his previous headset mic seemed to slip out of place at the worst possible time. And while it didn't sound all that bad, neither was it a great sound. As the music pastor, I asked a number of trusted friends for their suggestions for an upgrade. The DPA 4066F came out on top by a comfortable margin, and that was confirmed by our Sweetwater rep.
Its sound is rich and full, without being harsh, and it works perfectly with our wireless system. It's light weight, comfortable and nearly invisible, and it stays where you put it. We have only used for a few weeks, but it seems to be well designed and sturdy enough for years of trouble free use, especially if designated for one person. It might not be the best for multiple users with varying size and shape of their faces. The only reason I'm not giving it a full five stars is its price. I'm not quibbling - it's worth every penny - I'd just be even happier if was less expensive. Still, would I buy it again? Yes, absolutely!
