Australian microphone company Rode have established themselves as one of the top mic manufacturers in the world. Their outstanding build quality, backed up by a 10 year warranty, and excellent clarity, makes them a popular choice for a multitude of recording assignments. The NT5 pair gives you two NT5 microphones with identical sonic charateristics, meaning you can use them as a pair together (for example on drum overheads) and know that between them they are giving a true representation of the sound.
Here's what Rode say about the NT5:
The NT5 is the perfect small-diaphragm condenser microphone for recording acoustic instruments, drum overheads, cymbals, live performances and other sound sources which benefit from stereo miking.
This compact externally polarized mic, sold in matched pairs, employs a .5" capsule and top-quality components throughout, and is simply awesome in stereo X/Y mic setups.
Also perfect for individual instrument miking applications.
