Update the firmware for your Kirkland Signature hearing aids
If you use Kirkland Signature hearing aids from Costco, update their firmware to use them with your iOS device if it has iOS 9.2.
When you update your iOS device to iOS 9.2, it will unpair your Kirkland Signature hearing aids from your device. You need to make an appointment with your Costco audiologist to update the firmware for your hearing aids. After the firmware is updated, you need to pair your hearing aids to your device again.
