Hear Wave In-Ear Monitors

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

 Hear Wave Custom 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

British company Hear Wave was founded by Lewie Winters after he learnt the hard way about the importance of hearing protection. Lewie damaged his ears while drumming in a rock band for five years. Once he did start looking into hearing protection he found there weren't any custom affordable options on the market. Lewie founded Hear Wave with the express aim of offering effective and obtainable hearing protection and in-ear monitors to both professional and up and coming artists. Today, Hear Wave products are used by musicians, engineers, audiophiles, motorcyclists and athletes.
