This product is a genuine GN ReSound item, not an imitation. Each model includes 10 retention locks. Through the purchase menu options, you can choose compatibility with either Surefit 2 receivers or Surefit 3 receivers. This product helps keep the hearing aid speakers firmly in the canal during talking, chewing, and most physical activities. These retention locks can wear out over time, and it is recommended to replace them approximately every 6 months.
On the tip of the hearing aid speaker you will the find the letter that corresponds to the power level of your speaker.

Hi, can my Imagine hearing aid use this?
Hearing Shop –
Hello, if you are referring to the Beltone Imagine hearing aid, it can be used. You need to choose Surefit 3. We will compile a list of compatible models later.
