How to find the size of the concha lock:
When you remove the dome, there is a number and a letter printed on the speaker itself, e.g., 2M – here, the number 2 indicates the length of the speaker tube, and the letter M indicates that it is a Medium speaker. In this case, you should choose a Medium concha lock. If it says S, you should choose Small, and if it says P, you should choose Power.
Features:
Support legs for all Siemens, Signia, and Rexton hearing aids. Different sizes for S (Small), M (Medium), and P receivers (Power – large). Easy to handle.
