As an audiologist with experience fitting a wide range of hearing aids, open fit hearing aids are one tool in the toolbox. These hearing aids are very popular among patients with normal low frequency hearing and patients on the lower end of the hearing loss spectrum.
However, they're not the right option for everyone and come with their own list of pros and cons. In this article, I will explain what open-fit hearing aids are, their pros and cons, and the different styles that exist.
What is an Open Fit Hearing Aid?
An open-fit hearing aid is a type of receiver-in-the-canal (RIC) or behind-the-ear hearing aid that is fit with an open-style dome tip.
The difference is in where the speaker (or receiver) is located. A RIC hearing aid places the receiver directly in the ear, while a BTE attaches to the hearing aid and funnels the sound through a slim tube and dome tip. What sets it apart is its unique design that permits a certain amount of low-frequency sound to leak out. This feature minimizes the occlusion effect, a common problem associated with more closed-fit hearing aids where users with normal low-frequency hearing may hear their own voice as overly loud or distorted. Primarily, this style of hearing aid caters to individuals with normal low-frequency hearing but require some degree of amplification in the high frequencies. Thus, open-fit hearing aids offer a more natural listening experience, especially for those whose hearing loss is predominantly in the higher frequency range.
Open dome tips will look slightly different depending on the manufacturer but have vents or holds in the dome that allow sound through. Read more about earmolds and domes here.

- "I had gotten so used to diminished hearing, I had no idea what I was missing. I no longer say “can you repeat that” or “what?” And my phone rings in my ear and all I have to do is tap the unit behind my ear. No more fumbling to get me phone out of my pocket in time to answer." - Richard
- "I love my new Resound Nexia 9. They seem to pick up sounds my previous 5-year old hearing aids picked up and they seem to process background noise much better. I am very happy with my purchase." - Mitch
- "My new Nexia “ears “ are very comfortable behind the ears. They seemed very loud at first but I have adjusted and are obviously better than my old “ears” . The sound is clear and less tinny . I can hear a phone conversation very clearly using the Bluetooth ability, although I still need my phone very close for the caller to hear me. After a day of wearing my “ears” the left one hurts, I think from the wire, however I have not had a follow up appointment so that may be fixable. The right side is no problem." - Fiona
- "The rechargeable battery is a HUGE plus—no more keeping batteries on me at all times. The moisture resistance is another plus—no more bulky desiccant case. The charging case is small enough to be easily portable, but might be a bit uncomfortable in a pocket—maybe in a jacket pocket. It took me a few days to figure out a good workflow for getting the hearing aids to connect and stay connected to my Pixel 5 (listed on the manufacturer's website as compatible). The connectivity is good when it works but sometimes one of the hearing aids drops out and has to reconnect. I was not able to get them to connect to my work computer (a MacBook) using MFi." - Matt

Wearers praise its sound quality and robust Bluetooth streaming. The main complaints we found relate to the larger size and occasional automatic mode switching. Some highlights from our partners at ZipHearing.
- "Wearing these new Phonak Sphere Hearing Aids has been very comfortable and an easy adjustment for me. These are my first hearing aids and the sound with them on sounds very natural. I've been able to understand my friends in a crowded restaurant and have been able to turn off the closed captioning on my TV. The Bluetooth feature has worked well for both streaming music and phone calls. I haven't found any drawbacks yet!" - Eileen
- "I have been wearing hearing aids for 6 years. I started my journey with ReSound which lasted nearly 5 years. I then went to Costco and discovered Costco aids are fine for people with modest hearing loss, but I needed more. I then went with Phonak Sphere and have been very happy. I am active and discovered early on the aids I had purchased were being negatively impacted by sweat. Phonak replaced them with water resistant aids for a very small charge. I am very pleased with my new aids." - David
- "Sound quality is excellent. Definitely an improvement over previous HA. Still trying it out in noisy environments but I definitely see an improvement when in noisy situations in understanding speech." - Ken
- "I am currently wearing the Phonak Audio Sphere 90 hearing aids. Had them about two weeks now and the sound quality is very good. I am a bit frustrated with the Automatic program selection as it does not really seem to pick the correct program for the situation. I have not noted the sphere function working as of yet, even though I have been in a few very noisy situations. They are comfortable and only took a few days to adapt to the thicker design of the body. The battery life is exceptional. After wearing them for 15 to 16 hours they still have 45 percent batter life. The only other complaint is the charger case. It is not easy to get they in and almost kink the wires to the domes. I wish they were bigger like my previous Marvels." - Brian

- "I've had these Oticon Intent hearing aids for a couple of weeks now, replacing Phonak Audio Lumity hearing aids. My impression is that I am hearing sibilant sounds slightly better and hearing conversations in restaurants slightly better. Even slight gains mean a lot to me. I have moderate hearing loss in the upper registers (normal in the lower). Anything that improves comprehension is welcome. In addition, the design of these hearing aids makes them more comfortable for me than the Phonaks and I wear them all the time without noticing that they are in except very occasionally feeling a little itching in the left ear, which goes away if I take out the hearing aid for a moment and rub the area. I would recommend these hearing aids to others." - John
- "Certainly like the change of hearing clarity. Very simple to use without making adjustments due to background noises or audiences. Very comfortable and no feedback. Glad I moved forward with Oticon Intent." - David
- "These hearing aids are great for me. I am able to hear with no problem at all. they are just as good or better than another brand that I tried that cost over 3 thousand dollars more. they are doing fine and I use them everywhere. I am outside most of the time and they do fine by staying in and not having to worry about them falling out or getting knocked out of my ear." - Stephen
- "I have been wearing HA for over 10 years. Experience with COSCO and others. Although these took some getting used to, my conversational hearing has greatly improved. My husband and friends have noticed without my asking. Still have to get used to the sound of my own voice - which is strange to me - but patience prevails. The music setting works pretty well such that I have resumed playing piano - which I had abandoned. This was an unexpected element in my hearing impaired world! While no hearing aids can provide total hearing correction, I no longer feel isolated in conversational situations. Thank you to the engineers at Oticon!" - Arlene

Pros of Open Fit Hearing Aids
- Natural sound quality: As mentioned before, open-fit hearing aids allow for a more natural listening experience by reducing the occlusion effect.
- Discreet design: Open-fit hearing aids are usually small in size and have a sleek design that makes them less noticeable when worn.
- Comfortable fit: The open dome tip provides good ventilation and prevents the feeling of fullness in the ear, making it more comfortable for extended wear.
- Immediate fit: There is no need to wait for a custom earmold to come back, as dome tips offer an immediate fit and come in a range of sizes.
- Cost savings: some clinics may charge an additional fee for an earmold.
Cons of Open Fit Hearing Aids
Despite their many advantages, open-fit hearing aids are not suitable for everyone. Here are some of the reasons why:
- Insufficient Amplification: Patients with a steep sloping loss, flat hearing loss, or more than a mild hearing loss may find that open-fit hearing aids do not provide enough amplification. This means that they might struggle to hear clearly, especially in environments with a lot of background noise.
- Limited Directional Microphone Control: Open fit hearing aids naturally allow more outside sound into your ear canal which gives the device less control over what you hear.
- Less Comfort and Retention: An earmold will always provide a more customized fit than a dome tip. An earmold has the best retention options and can be comfortably fit to the shape of your ear. While the different size dome tips work for most ears, they aren't the right fit for everyone.
Consult a Hearing Care Professional
If you're unsure whether open-fit hearing aids are the right solution for your hearing loss, consulting with a hearing care professional can be of immense help. They have the expertise to assess your hearing condition and lifestyle, and can provide more detailed information on the suitability of open-fit hearing aids based on your specific needs.
They can also guide you through other potential hearing aid options and assist in making an informed decision about your hearing care. Always remember, the best hearing aid for you is the one that meets your hearing needs, fits your lifestyle, and is comfortable to wear.
Final Thoughts
In conclusion, finding the right hearing aid can feel like navigating a labyrinth, especially with the array of options available. Open-fit hearing aids stand out for their unique design and the natural sound quality they offer, making them a popular choice among individuals with normal low-frequency hearing but require some degree of amplification in the high frequencies. However, these devices are certainly not a one-size-fits-all solution.
They come with their limitations, making them unsuitable for some people. Hence, it's crucial to consult with a hearing care professional who can provide expert advice tailored to your specific hearing situation and lifestyle needs. Remember, the goal is to find a hearing aid that not only enhances your hearing but also aligns with your lifestyle and comfort.
Various styles of open fit hearing aids are available in the market, each with their unique features catering to different preferences. Whether you need an immediate fit, a discreet design, or a device capable of connecting to your Smartphone, there is something for everyone.
