Light and comfortable, Ace™ primax is the smallest in the family of RIC hearing aids. Despite its compact form, Ace primax is packed with powerful features to deliver the natural ease of hearing. Ideal for first-time wearers and those who demand the utmost in discretion and functionality, the new Ace primax RIC sits unobtrusively behind the ear.

Is ACE suited to you?

Before proceeding with a demo, you will need to send us your audiogram for our in-house audiologist to review and determine whether your hearing loss is suitable for a ACE.  We may also need to phone you to determine a number of other factors.

To enquire further about suitability of the Siemens Signia ACE hearing aid, contact us today by sending your enquiry and/or audiogram.

How is ACE custom programmed?

The ACE Primax demo hearing device will be programmed to your audiogram by our in-house audiologist and shipped directly from The Hearing Care Shop to you. We’ll include a range of domes in different sizes, so you can easily fit and adjust them to your personal preference.

You can trial the ACE demo for two weeks to experience if the ACE Primax is suitable to your hearing loss and needs!

Trial period

The trial period for the ACE demo hearing device is two weeks.  The ACE demo hearing device is not a fully functional hearing aid, it has an integrated clock that will stop the demo hearing device from operating after three weeks of it being programmed.

A fully functional ACE Primax hearing aid is required to be programmed by a clinician at a Partner Clinic in conjunction with a fitting appointment (approx 1 hour).
