Minerva In-Ear Monitors

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

 Minerva 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.

Love Your Ears & Protect Your Hearing with REV33

Minerva has decades of experience in the hearing protection industry having been founded in Wales back in 1952. Pioneers in custom ear moulding, Minerva set up the very first ear mould laboratory and invented many of the materials and processes used within the industry. They continue to be trailblazers and are the first UK laboratory to use 3D printing to scan and design their products, which offers even greater accuracy and comfort to wearers. Minerva have made over 8 million ear pieces and their products are used by many prestigious companies including the NHS, F1 teams and the Royal Mint to name a few.
