64 Audio In-Ear Monitors

REV33 is an innovative new product for musicians, engineers and audiophiles
to use in conjunction with 64 Audio IEM (in-ear-monitors).

 1964 Ears 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


64 Audio, formerly known as 1964 Ears, was founded by sound engineer Vitaliy Belonozhko who, as a direct result of his personal experience using existing brands, felt that the market needed a better and more affordable solution to in-ear monitoring. The 64 Audio products available today (both custom and universal fit) are the result of many months of extensive sourcing, designing and field testing. 64 Audio have recently partnered with Stephen Ambrose (who invented the first in-ear monitor in 1964 - yes that fact does relate to the choice of company name!) to introduce a revolutionary audio technology called ADEL.
