New Hearing Aid Side Effects
Common hearing aid side effects include headaches, discomfort, issues with new sounds/sound quality, and itchiness caused by irritation and earwax buildup.

Updated:
At a glance:
- Hearing aid side effects are generally mild, and you should reach out to a hearing care professional (audiologist) immediately if you experience ear pain.
- Ensuring that your hearing aids fit properly and get regular fine-tuning from your audiologist is key to better hearing free from side effects.
- The hearing aid adjustment period takes time, so it’s important to be patient with your new device.
For seniors with mild to profound hearing loss, a new pair of hearing aids can play a key role in not only daily quality of life, but also in preserving hearing health. However, as with any medical technology, some mild side effects are possible.
To help ensure that you and your loved ones enjoy the best hearing aid experience, we’ve analyzed the most common side effects users report, as well as how you can limit them. Read on to learn how you can safely reap the benefits of hearing aids, and what to do when things go wrong.
The Most Common Side Effects Hearing Aid Users Experience
For new hearing aid wearers, there are a few possible negative side effects to be aware of. For the most part, these side effects should be mild and fixable in follow-up appointments with your audiologist. For instance, you may experience:
Headaches
As your brain slowly adjusts to the many sounds it hasn’t processed clearly in some time, mild headaches can arise. They’re particularly common in the first few days of wearing the new device. Once you start to adapt, headaches should naturally fade. If they persist or worsen instead, your audiologist may need to adjust the amplification settings or improve the fit.
Discomfort
New hearing aid wearers sometimes report a feeling of fullness or pressure in their ear, especially during the initial adjustment period. Usually, this is just a matter of getting used to having something inside the ear canal, and it tends to resolve on its own with regular use. However, if discomfort persists, there may be a fit issue that needs to be addressed.
Sound Level Issues
As you adjust to your new hearing aids, you may notice previously muffled background noises becoming too loud. While this is part of the adaptation process, you can always tweak the volume settings for effective noise reduction. On most hearing devices, you can use either the onboard button, smartphone app, or paired remote control to raise or lower the volume. If none of these options are present, you may need to contact your audiologist for assistance.
Poor Sound Quality or Feedback
When you use hearing aids, sometimes noisy environments like crowded spaces or windy sidewalks can cause unpleasant whistling or crackling noises. It’s also possible for them to experience interference from electronic or Bluetooth devices. These side effects are fairly rare, but if adjusting the volume doesn’t remedy them, an audiologist can find the cause of the feedback and make adjustments.
Itchy Ears
While hearing aids should not cause ear infections, users with sensitive ears, skin conditions, or poorly-fitted devices might feel an itching sensation in their ear canal. Your audiologist can help by either pairing you with a device that has a different shape or by recommending specific soothing lotions. Physical ear pain is not a normal side effect, and you should contact an audiologist or primary care provider immediately if it occurs.
What Should Wearing a Hearing Aid For The First Time Feel Like?
When you wear a new pair of hearing aids for the first time, it’s normal for it to feel somewhat jarring or overwhelming. Physically speaking, you’ll be able to tell that there’s a foreign object in your ear. Mild pressure is the most reported sensation, and should fade over time.
More noticeably, sounds will appear much louder, sharper, or “echoey,” especially your own voice. You might also pick up on high-frequency sounds you haven’t heard in a while, like birds, typing, or running water. These experiences should become more normal with time, but you can lower the volume if you feel too overwhelmed or confused.
Finally, because your brain needs to work hard processing the new inputs, it’s also common to feel fatigued after a few hours of wearing your new hearing aids. As your brain adapts, it will consume less energy to hear the sounds around you.
Tips For Getting Used To Your Hearing Aids
For most users, getting used to hearing aids takes 30 to 45 days or more. Set yourself up for long-term success with these tips:
- Try them on in a controlled space: Before you try wearing them to your favorite diner or bar, first take a few hours to wear them in a quiet part of your home. This reduces the chance of being overwhelmed by new sounds.
- Practice wearing them: Spend 3-4 hours wearing your hearing aids in quiet spaces to acclimate to how they feel. You can also read aloud or listen to audiobooks to expedite the adjustment process.
- Use soft sounds as a reference point: Use your refrigerator, heater, air conditioner, or other sources of white noise to find the ideal volume settings, long before you throw yourself into noisy environments.
- Gradually increase wear time: Slowly work your way up from wearing your hearing aids for a few hours to 8-10+ hours a day. Carefully remove them if headaches or fatigue are affecting you.
- Regular check-ups: In the beginning, you should meet with your audiologist every 2 weeks for adjustments, reporting on all the experiences you’ve had for the most accurate improvements. Once you’ve adapted, you should still visit them annually or semi-annually.
Our Takeaway: Most Hearing Aid Side Effects Are Temporary and Improve As You Adjust
If your audiologist recommends hearing aids after your hearing test, you should expect a few different side effects. As your brain adapts, the most common side effects are headaches, physical discomfort or itchiness in the ear, and issues with sound level or quality. Many of these naturally fade with regular use, but you can also hasten the adjustment process by gradually wearing them in different settings, changing the volume, and scheduling follow-up appointments with your audiologist.
Ear pain or infections are not common side effects, and you should contact your audiologist and primary care provider immediately if you experience these issues.
Ultimately, mild side effects are a normal part of wearing hearing aids for the first time, and shouldn’t be cause for concern.
Frequently Asked Questions (FAQs) About Hearing Aid Side Effects
The typical adjustment period for hearing aids is around a month (30 to 45 days). However, adaptation can take up to 4 months if you have profound hearing loss, issues with the fit, or need volume adjustments. Realistically, how long it takes the brain to adapt is different for each person, so patience is key.
While a bit of discomfort is normal for the first few days, you can tell if your hearing aids fit if they feel comfortable all day, secure when you move your head, and provide clear sounds without feedback or whistling.
No, hearing aids do not cause tinnitus. Tinnitus is usually caused by damage to the inner ear due to hearing loss, so hearing aids can actually lessen the problem.
Hearing aids should not increase your risk of infection, but always be sure to clean and maintain them properly to prevent harmful debris buildup in the ear. Nightly removal and dehumidification are vital for your long-term ear health.
No, you shouldn’t share hearing aids with anyone. Aside from the risk of unwanted microbes spreading from one person to the next, every prescription is also different. Imagine trying to wear someone else’s glasses, and how that can cause vision impairments, headaches, and fatigue. Swapping hearing aids with someone else has a similar effect.
You can prevent harmful earwax buildup by cleaning devices nightly with a soft cloth or brush, replacing wax guards every few months, using a dehumidifier, and taking them in for professional maintenance at least semi-annually.
Yes, because most side effects are related to the volume, fit, and how you’re adapting to both, hearing care providers (audiologists) can remedy many issues in-house.
