This is the microphone used by Billie Eilish. Used only about 3 times at home. The sound is also fine. The TLM 103 is a large-diaphragm condenser microphone that follows the K 67/87 capsule of the Neumann U 87. Its sound is Neumann-esque, following the U 87, while achieving an affordable price by streamlining features, such as only having a cardioid polar pattern. It can be used for vocals, as well as guitar, piano, and instrument recording, making it a truly "modern U 87" microphone.
