The sE7 matched pair stereo set is a set of high-quality back-electret small-diaphragm condenser microphones intended for a wide range of studio and live sound applications, from acoustic guitars to pianos to drums and beyond. They are super quiet, offer a super clear sound, come equipped with a pad and high pass filter, and come in all-metal housing for durability. It is a great pencil microphone set with a low price tag but punches way above its weight.
