Receiver Tubes for Sonic Innovations for MNR and N BTE hearing aids:

The higher the number on the receiver, the longer the tubing will be. If you currently have a receiver, the size you need will be printed in blue or red on the end where the dome connects. (You may need a magnifying glass and good lighting to see this). It is also HIGHLY recommended that you have a professional change the receiver for you. Find information and links to Domes under the Related Products tab.

Note: All Tube orders are non-refundable if opened.
