How to identify your retention size:

To ensure the correct fit when selecting a hearing aid retention lock, it’s important to match the variation of the lock to the power level of your receiver wire. Your receiver will be either  Standard (S), Medium (M) or Power (P) , and this is indicated by a small S, M or P printed on the end of the receiver. Once you’ve identified whether you have a Standard, Medium or Power receiver, simply choose the corresponding retention lock in the same variation for optimal performance and comfort.
