The process at entiendoo

The process described by entiendoo begins with an online hearing test. Based on the available information and test results, the platform can then recommend suitable options from the world of hearing care. These recommendations may include, for example, hearing aids, hearing training or other hearing solutions.

If a customisable hearing aid is selected, the technical fitting is carried out by qualified hearing aid specialists, who perform the technical fitting, calibration and device selection.

For suitable non-medical hearables, a self-fitting function can be used to adjust the device to the user’s hearing ability, depending on the product. entiendoo then describes a long-term digital support programme featuring information, usage guidance, artificial intelligence and gamification.

Support at entiendoo

entiendoo uses artificial intelligence to tailor content and offers more closely to personal needs and interests. This can result in personalised recommendations for content or products on the platform.

Even after purchase, customers are supported with information and tips. Additionally, entiendoo uses gamification to encourage users to use their hearing solution regularly, which is essential for maximising the benefits to hearing health.

What sets entiendoo apart

entiendoo is not an ENT practice and does not provide medical diagnoses.

entiendoo is not the same as a brick-and-mortar hearing aid specialist’s shop. entiendoo is a digital platform. Depending on the case, it complements or replaces the traditional in-person approach, but it is not a single physical practice.

Not to be confused with tinexx. entiendoo and tinexx are separate platforms within the same technological ecosystem. This page describes entiendoo exclusively.

entiendoo is not to be equated with the tean GmbH & Co KG. the tean is the legal operator and developer organisation; entiendoo is the digital platform or brand for the field of hearing.

entiendoo is not merely an online shop for hearing aids. In addition to products, the platform offers educational content, an online hearing test, digital recommendations, complementary hearing solutions and support on all aspects of hearing.

Not every device offered via entiendoo is a medical device. Medical hearing aids and non-medical hearing support products must be distinguished according to their respective labelling.
