Phonak - Unitron Hearing Aid Domes

Phonak – Unitron Hearing Aid Domes are the small silicone bell-shaped pieces located on the end of a thin tube or Receiver-In-Canal (RIC) hearing aids. This is the actual physical piece that is inserted in your ear. The proper choice of style and size dome makes a significant difference in comfort and sound quality when wearing hearing aids.

Phonak – Unitron Hearing Aid Domes come in three (3) styles (open, closed and power) and each with three (3) sizes (small, medium and large).

Note:  Phonak no longer produces the clear domes.  All domes will be the dark or smokey gray color.

Phonak – Unitron Open Fit Hearing Aid Domes have openings in them that allow sound to pass through from outside of the ear through and into the ear canal. This open fit concept allows for a very natural sounding hearing experience with hearing aids. This open fit style also helps prevent the occlusion effect or the plugged up feeling some experience while wearing their hearing aids.

Phonak - Unitron Open Fit Hearing Aid Domes in Small, Medium, & Large Sizes.
Phonak - Unitron Closed Hearing aid Domes in Small, Medium, & Large Sizes.

Phonak – Unitron Closed Hearing Aid Domes are mostly closed hearing aid domes with small vents. These domes are more occluding and hold sound in the ear more than open domes.

Phonak - Unitron Power (Double) Hearing Aid domes in Small, Medium, & Large Sizes.

Phonak – Unitron Power (Double) Domes are the most occluding hearing aid domes. Power Domes have no vents. These domes hold the most sound in the ear and are generally used for low frequency and more severe hearing losses.

  • Small – approx 5 mm
  • Medium – approx 7 mm (Most Common)

  • Replace every 6 – 10 weeks or whenever they pull off the hearing aid tip too easily.
  • Always ensure that the new replacement dome is pushed firmly onto the tubing completely before inserting the hearing aid tip into the ear canal.

  1. Garrett P. From Frisco, TX.

    Work great. No issues. Normal transaction.

  2. Larry B. From Bend, OR.

    I was concerned about ordering these because it is difficult to discern the size from the description but I picked a medium and got lucky because it was a perfect match to what I had. The smoky color was also a perfect match. Fast service and delivery. I am happy with the product and purchase.

  3. Coretta W. From Spencer, IN.

    These tips fit my Phinak RIC hearing aids perfectly. They are comfortable in my ears. Good pricing and quick shipping from HearSource.
