The DPA d:fine sets the standard for
ease of use and sound quality, but the price is obscene. The Countryman E6 is good for sound quality, but a lot harder to fit to people. On the single ear model, shaping the
wire to fit someone's ear is an exercise in frustration for me. I haven't gotten my hands on a dual, but assume it would be easier to fit for stability.
I recently recorded an event where the
house sound guy brought Mic Madness duals. They sounded good and needed just a touch of EQ to add presence. For the price, I would happily buy them and toss the whole thing when the
cord inevitably breaks. I regret that I didn't have time to
play with
fitting them on someone, but it didn't take the
house guy long to put them on the talent.
YMMV.
