A revolutionary in vocal sound isolation! Please try it at the store. A new idea: "covering the back of the microphone." Harmful reflections caused by the shape of the room and various noises that get into the microphone are some of the biggest problems when recording. The Reflexion Filter is a powerful tool that effectively eliminates this problem and delivers clear sound. The exterior is made of aluminum, which diffuses sound, and the interior is made of a thread-like fiber material that has excellent sound absorption properties. It's portable and easy to set up, so it's extremely effective not only for recording vocals and narration, but also for guitar and bass amps and even for external recording.
