The Evoke2 Ambient features not one but two single wide band balanced armature drivers that punches out a low end, which will really make you feel the music. Also featuring ACS exclusive Sound Stage Imaging (SSI) technology, the Evoke2 allows you to hear parts of the music you never knew existed before. This together with a precision tuned vent and filter to help cancel the occlusion effect and stay in touch with your environment will really evoke a new listening experience.

If you are looking an entry level in-ear monitor with professional specification, the Ambient Evoke2 is the one for you.

Please note: To manufacture your custom-made, bespoke fitting IEMs we require impressions of your ears. Our ear impression service is available throughout the UK and is provided free of charge with your purchase with one of our recommended trade partners. Manufacture times can vary dependent on demand.

    Order Notes

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 at the factory it has optimum contact to the cable socket, therefore we strongly recommend that you don’t disconnect the cable unless it requires replacing.

Care and Maintenance

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 your in-ear monitors – this will eventually put strain on the connector and will damage the cable or socket.
  • Ensure moisture from either humidity or sweat is removed straight after use. We supply silica gel and a zip up pouch for this purpose. We recommend using your ACS Revivo Dryer and Sanitiser after each use.
  • Finally, read the instructions supplied and watch our cable fitting guide.
