Is SILK 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 SILK.  We may also need to phone you to determine a number of other factors.

Email to further enquire about suitability and/or to send your audiogram.

How is SILK custom programmed?

The SILK 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 silicon sleeves in different sizes, so you can easily fit and adjust them to your personal preference.

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

Trial period

The trial period for the SILK demo hearing device is two weeks.  The SILK 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 SILK Primax hearing aid is required to be programmed by a clinician at a Partner Clinic in conjunction with a fitting appointment.
