I was really impressed with the wider and more uniform frequency response of the Earthworks mics and I love the fact that I don’t encounter phase cancellation issues when using multiple microphones together. These mics have excellent rear rejection characteristics, which eliminates unwanted sounds and they handle the fast attack transients beautifully.
