The world’s most famous studio mic.
Since its introduction in 1967 as a FET-based successor to the legendary U 67, the Neumann U 87 Ai has been one of the world’s most popular and in-demand studio microphones, and for good reason. It achieves a miraculous sonic balance of remarkably flat response, tempered with a personality and vibe that shines through. Versatile enough to use for vocals, acoustic instruments, drum overheads, even for guitar and bass cabinets, the U 87 Ai’s natural sound and charismatic midrange has made it a microphone that engineers in the know reach for when they need to make sure that track is everything in can be.
