Read Audio In-Ear Monitors

REV33 is an innovative new product for musicians, engineers and audiophiles
to use in conjunction with Read Audio IEM (in-ear-monitors).

 Read Audio In Ear Monitors

  • The REV33 reduces noises and distortions that are inflicted into the audio by correcting the electrical relationship between the amplifier and driver. This is achieved without processing the actual audio.
  • The REV33 dramatically reduces the symptoms of temporary-tinnitus, ear-ringing, ear-fatigue, buzzing & dampened hearing caused from using IEMs and headphones.
  • The REV33 is physically small and contains an analogue passive PCB. It is supplied with a small leather pouch that attaches to your wireless pack or connects in line with your listening device.
