We have introduced our patent-pending IRIS and exclusive SSI technology across our entire IEM line-up.

IRIS – Intelligent Resonance in Silicone is a patent-pending technology we have created to maximise the potential of miniature balanced armature speakers. IRIS construction methods allow for very precise acoustic tuning to deliver our unique ACS sound signature. IRIS brings an added dimension to music in a way that mimics the warm, lush and open sound that valve amplifiers provide.
SSI – Sound Stage Imaging is a tuning technique achieved by using our own purpose-designed manifold technology. Implemented into our custom and universal in-earphones, SSI positions the audio into a wider array than other earphones, bringing a superbly defined and very detailed response to further enhance your listening experience, positioning all the instruments as if you were sitting in front of the stage listening to the live performance.

The ACS Evolve IEM’s come with the highest quality Kevlar cables

The cable fitted to your ACS monitors is of the highest quality. Manufactured to our own specification, each cable contains 80 strands of 100% oxygen-free copper with each strand plated in pure silver. Aramid fibres (Kevlar) are woven into the twists to provide exceptional pulling strength and breaking strain. The sheathing on the cable is treated to dismiss harmful UV rays and will not discolour or oxidise like many other inferior cables. The design of the cable provides the best connectivity between your audio source and the earphones. When the cable is fitted in the lab it has optimum contact to the cable socket, therefore we strongly recommend that you don’t disconnect the cable unless it requires replacing.

Combining the latest ACS technologies and the new detachable cable system the Evolve IEM delivers a truly reference quality, high fidelity In-Ear Monitor. If you are looking for a well-balanced, detailed and accurate sounding IEM without breaking the bank then the Evolve is the one for you.

Care and maintenance of your Evolve Triple Driver Monitors

We make our in ear monitors with pride and like all things worth having, they are worth looking after. Just follow these simple rules and you should receive many years of trouble-free service.

  • Check the sound ducts after each use and use the wire pick supplied to remove any ear wax that has made its way into the tubing
  • Never use the cables to remove the IEMs – this will eventually put strain on the connector and will damage the cable
  • Ensure moisture from either humidity or sweat is removed straight after use
