At the moment, a large part of the hearing aid brands on the market have connectivity for mobile devices. This feature offers a multitude of benefits that extend the range of control of your hearing aids. By connecting your hearing aids to your device you can receive everything that the mobile would normally emit through the speakers but directly to your ears through the headphones, thus providing greater clarity. Come on, as if your headphones were wireless hearing aid. Can you imagine how well phone calls can be heard using this connection method?

In addition, the application provides us with multiple control tools about our hearing aids, such as changing the volume, and offers us the function of remote assistance with your hearing care professional.

In this post we are going to explain in detail and in a simple way how you can connect your ReSound hearing aids to your mobile phone and the “Smart 3D” application so you can do it yourself.

The process of connecting headphones with android is different from the way to connect them with IOS, therefore, we are going to explain the two versions so that you can carry out the process using the operating system you have.

Regardless of whether you wear one or two hearing aids, the process will be exactly the same.

If you press here, we are going to direct you to the official ReSound website in a section where you can check whether the mobile phone you are holding is really compatible with the connectivity of Resound hearing aids or whether your hearing aids have a bluetooth connection.
