Phonak/Unitron Receivers 4.0 will work with several models. These receivers come as Standard, Medium and Power receivers. 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). Find information and links to Domes under the Related Products tab.
Note: All Tube orders are non-refundable if opened.
