We know that the variety of names can be confusing. In our product descriptions, you will find detailed compatibility notes for brands such as Phonak, Oticon, Signia, and many more. If you are still unsure, simply send us a quick photo of your hearing system via email or conveniently via WhatsApp. As experienced master hearing aid acousticians, we will reliably identify the correct spare part for you.

The length of your receiver (the numbering varies depending on the manufacturer, often for example from 0 to 4) and the power (S, M or P) are printed on your current receiver. If the numbers are no longer legible, that's no problem: S, M and P receivers have different designs, so you can compare your receiver with the pictures on our product pages or send us a photo by email or WhatsApp. We explain all the details in the guide Ex-Receiver defective: how to identify and replace it yourself. You can find suitable replacement receivers here.

Yes. Earpieces with a push/pull system (such as the SDS 6.0) can be changed without any tools, for all others there is our Ex-receiver tool. The change only takes a few minutes. A step-by-step video guide can be found in the Master Knowledge Library.

We'll never leave you alone with technology! That's why we created our comprehensive DIY section (Hearity Master-Knowledge Library). There, you'll find easy-to-understand video tutorials created by us. We'll show you step-by-step how to safely and professionally replace wear parts yourself.

For brilliant sound quality and the longevity of your hearing system, we recommend a change every 4 to 8 weeks. A replacement becomes absolutely necessary when the device becomes noticeably quieter or sounds distorted.
Our Expert Tip: To save on shipping costs and always have a timely replacement at hand, our practical annual supplies are particularly popular.

In most cases, this can be resolved independently. If the sound is quieter or muffled, the wax filter or dome is almost always blocked; less often, it's the battery, program, or receiver. If there is whistling (feedback), it's usually due to the fit of the earmold or dome. Our two guides will walk you through the check step-by-step: Hearing aid too quiet or muffled and Hearing aid whistles.

Switch off immediately, remove the battery or do not charge it, dry it externally and allow it to dry thoroughly, preferably several times in an electronic drying box. Please do not use a hairdryer or place it on the heater or in the oven. All steps in detail can be found in the guide Hearing aid got wet: First aid.

Perspiration and humidity are the most common causes of expensive technical defects. By using electric drying stations daily, you remove moisture from the system and effectively protect the sensitive electronics from corrosion. This saves you unnecessary repairs in the long run.

Some older filters are no longer manufactured. The CeruShield Disk, for example, has been discontinued by Phonak; it was used in 4.0 generation receivers. We deliberately do not offer it and instead show you the permanent solution: the uncomplicated switch to the 5.0 receiver with the CeruStop system. Details in the guide CeruShield no longer available: your options. If you are unsure which filter fits your device, simply send us a photo of the receiver.

A clear yes. The sensitive technology of your hearing system cannot tolerate cheap copies. We obtain our cerumen filters, domes, and care products exclusively directly from leading brand manufacturers or strictly certified specialist wholesalers. You receive exactly the same uncompromising quality from us as you would in your local specialist store.

Don't worry, that can happen! As long as the factory packaging is unopened and the hygiene seal is intact, you can easily return the item to us within 14 days. In this case, just send us a short email and we will help you with the uncomplicated process.

We know from experience how important your hearing system is for your everyday life. That's why we work especially quickly: Orders received by 12:00 PM on weekdays usually leave our warehouse on the same day.

You can pay conveniently and securely, including with PayPal, Klarna, Apple Pay, Google Pay, Shop Pay, and common credit cards. Within Germany, we ship exclusively with DHL and offer free shipping for orders over 50 Euros; for orders below that, a shipping fee of 3.90 Euros applies.

Statutory health insurance usually covers the costs of repairs, but not for traditional care and consumables such as cleaning cloths, filters, or standard batteries. These items are a private investment in the longevity of your device. However, we will of course provide you with a proper invoice, which you can submit to your private supplementary insurance if necessary.
