30% higher risk of falls, a leading
cause of injury in older adults
40% higher risk of depression
Greater social isolation
and withdrawal

What Are The Benefits of Hearing Aids?
Hearing aids do more than improve hearing. They help you stay connected, confident, and engaged in everyday life
Clearer Conversations
Hearing aids improve speech clarity up to 40% compared to other hearing aid technology, making it easier to follow conversations in quiet settings and noisy environments without constantly asking others to repeat themselves.
Better Brain Health
Research shows untreated hearing loss is linked to increased COGNITIVE decline and DEMENTIA risk. Treating hearing loss helps keep the brain stimulated and engaged, supporting long-term brain health.
Improved Balance and Safety
Hearing plays an important role in spatial awareness. Wearing hearing aids has been shown to reduce fall risk and improve awareness of your surroundings.
Stronger Social Connections
Hearing aids make it easier to stay involved in conversations with family and friends, reducing isolation, frustration, and withdrawal from social situations.
Greater Confidence and Quality of Life
When hearing becomes easier, daily interactions feel less stressful. Many people report increased confidence, improved mood, and greater enjoyment of everyday activities.

My husband and I had the most informative and pleasant visit with Kim. We both had been to other places and had other hearing products. Neither of us had been as thoroughly tested and then shown what could be done to improve our hearing. We were both fitted with new hearing aids and are very pleased with them. Thanks Kim for your patience and taking the time to explain our hearing loss and what hearing aids could do to improve it.
I could not have asked for a better experience! Kim was thorough in every aspect of my visit. We discussed options and compared my current hearing test results to my last hearing test. I did my research and I was impressed with the more than 90 5 star reviews K&K have rightfully earned.
I had a great visit. Kim is very knowledgeable and makes the testing very easy. His explanations are detailed and thorough. He answered all my questions with detail and patience. Being greeted by Dena starts the whole visit off with a very comfortable and fun experience.
The owner of this business is A # 1.very thorough and takes time to make sure that you are satisfied with your new hearing aids. Would highly recommend you go see this business if you need hearing aids. Great business 👏
I’ve worked with K&K since I first got hearing aids four years ago. Kim and his team provided great assessment, explanation, provision, and top-notch ongoing customer service. Got the newest generation aids a month ago and couldn’t be happier. I highly recommend K&K Hearing Associates!
The customer service from start to finish was extraordinary. They take the time to educate you on the type of hearing loss you personally are dealing with. The options to help and the expectation you may get from the device. You will not find a better Hearing Center than K & K. Thank you
This is the second time I've been to K&K. I've updated my hearing aids, and I am very pleased. Mr Keller was, and is, professional, but he also puts you at ease. I will remain a client with K&K Hearing.
Kim Keller is superb in his talents to analyze and address hearing impairments. I have been a patient for 8 yrs and have had nothing but positive experiences. My most recent visit involved a VERY thorough assessment with excellent results. I highly recommend K&K.
My dad had gotten his hearing aids from K and K, and was extremely satisfied with them. So I knew without a doubt that was the place I was going to go. They did amazing work for me, I would highly recommend them!!!
I looked for the best and got the best! Kim sat down with my husband and I and he told us the tests he would be doing and explained the results to us. He took his time with us and even helped us set up an app on the phone. I am so glad we chose K&K!
I changed hearing clinics in July of 2023 because I was not satisfied with the hearing aids nor with the service. I came to K&K with some apprehension expecting marginal improvement. The service I received at K&K exceeded my expectations. Kim spent whatever time he felt was necessary tip satisfy my needs. The new hearing aids I purchased are definitely an upgrade. After a week and half of wearing them, I came back to have them programmed to mask my tinnitis. After an hour and a half of testing, Kim and a factory tech reprogrammed the hearing aids to customize to my needs. I am currently wearing them during all my wake hours to get used to them. Time will tell how well I will adapt to them. I appreciate all the time spent and care shown by Kim and his team to help improve my hearing and quality of life. Updated review (Oct. 2024 after 15 months of wearing experiences): Wearing my hearing aids became part of my daily routine because they did make a difference in my life. K&K accommodated my needs whenever I had real or potential issues with my hearing aids during the 3 month interval checks or in between times - always took great care to make sure I was comfortable. At the annual visitation for re-testing and re- programming, Kim took the time to first explain the process before proceeding. The tests indicated changes in both ears of different levels. Following Kim’s complete explanations of the meanings of my changes, he proceeded to re- program each hearing aid to be in sync with the test results. I immediately picked up of the improvements. To top off my annual visit, Kim set up my hearing aids through blue tooth to communicate with the Audibel app . on my phone. Now I can listen music, take phone calls and even monitor my health related vitals. If you’re searching for a very knowledgeable, experienced and mostly careing professional to help with your hearing impediments, I strongly recommend you stop in a visit K&K in Hagerstown Stan P
I've been going to Kim for hearing aids for several years now. I actually own two sets of hearing aids bought from Kim! Some years ago, I took my father to Kim who also bought hearing aids. These days you can get hearing aids from almost anywhere. But the best brands to buy are Starkey and Audibel- like what K&K sell! But the most important concern for hearing aids is service and support. Just prior to the pandemic, my 2 year warranty was about to expire when I had an issue come up with my original hearing aids. They sent them both to the factory and had them refurbished. I still use them today as spares and when I visit places where Bluetooth tech isn't allowed. My one of my new aids have needed work recently. They just issued me a brand new unit. BTW, they have also taken great care of my father. He lives in Ohio which makes things a bit more challenging! But both Kim and Deana bend over backwards to keep things working smoothly. Hearings aids for me was a challenge to get used to. I wasn't convinced I needed them at the time. But now, I truly struggled to stay engaged in conversation without them! My wife and children are glad I have them as well. If you or a loved one need hearing aids, I highly recommend calling K&K Hearing Associates with offices in Hagerstown and Frederick MD. They will take great care of you!
I am very pleased wt today's visit with K&K. I got both ears tested, one needed more help so the hearing aid was adjusted accordingly. Also both devices got a software upgrade. AND I got a quantity of wax removed from both ears. All and all a very good visit.
Meeting Kim Keller was a changing moment in my life that I will forever be grateful. He took the time to explain hearing loss to me that no one else had ever done. I learned so much from him that day. The hearing tests were thorough as well as enlightening. My husband saw a difference in me during the appointment and decided we were getting the hearing aids. What a difference!!! I had no idea just how much I had been missing. Kim is amazing to say the least. I don't have words to say just how grateful I am.
Kim and Diana were wonderful helpers and we so appreciate all they did to get me into new hearing aids! We will see them every three months for a cleaning and supplies! Thank you! And Merry Christmas!
Had a good experience with Kim. He tested my hearing and we saw there had been a decline. Kim is very knowledgeable and easy to work with.
Excellent staff, very knowledgeable and thorough, making sure you are taken care of and treated with the utmost respect. Would definitely recommend for anyone with a hearing problem.
WOW Just WOW!!! As a Vietnam War helicopter pilot and career a commercial pilot, I have been exposed to significant noise all my working life. I've been wearing hearing aids since 2013 made available through the VA. My hearing loss is profound and even with my VA hearing aids, which I replace every four years, as my wife would attest, my hearing is hit and miss. It is affecting my quality of life. On a whim, I went to K&K to see if there was anything that could be done to improve my lousy hearing. Kim took me through a detailed evaluation and carefully explained the dynamics of hearing measurement. When he did a comparison test between my present hearing aids and the Audibel Vitality AI aids he offered me, I was literally shocked by the discernable difference between the old and the new. On a graph depicting the difference of the test results, he explained that my old aids were not even reaching the range where I could hear acceptably. A chart depiction is one thing, but the actual experience of the improvement of both loudness and clarity is something one needs to experience for oneself to believe! Words can not express my gratitude to the folks at K&K for their excellent service, attention to detail, patience, and professionalism.
I have been going to K&K hearing for over 10 years and their support and service to address my hearing loss has been invaluable. Kim and his staff are always accommodating to my hearing needs and scheduling. And Kim’s technical understanding of auditory deficiencies and how best to address each client's needs far surpass that found in other low cost hearing aide ‘department’ stores. In addition, K&K provides continuous support to their clients through the years following the purchase, at no additional cost.
The whole experience was fantastic, from booking the appointment to getting new hearing aids. The hearing test was above and beyond the last places that gave me and maintained my hearing aids. I can hear better than before and understand my family better than before.
All I can say is today was the best of my life. I met Kim from K and K hearing to have my hearing checked I knew I was having a problem but they showed me I had a major problem a lot of hearing loss Kim was very professional during his testing he explained everything thoroughly to me and my wife never rushed us . I don’t know how to thank him enough walked out of there that evening with hearing aids and a changed life I want to thank them so much and if you’re in the need for hearing aids don’t hesitate K&k hearing in Frederick Maryland A1 Business thanks again Kim
Answers to Common Hearing Care Questions
What causes hearing loss?
Hearing loss can develop for many reasons and often occurs gradually over time. Common causes include natural aging (Presbycusis), long-term exposure to loud noises, genetics, certain medical conditions, medications (Ototoxicity), and ear health issues. In many cases, hearing loss is the result of multiple factors working together, which is why a professional evaluation is important to understand what’s happening and determine the most appropriate next steps.
How often should I have my hearing checked?
For most adults, a hearing evaluation every 1–2 years is recommended, as hearing can change gradually over time. You should schedule an evaluation sooner if you notice changes in clarity, increased difficulty following conversations, ringing in the ears, or concerns from family members.
If you are 50 years or older, it’s recommended to establish a baseline hearing evaluation every two years, even if you don’t believe you have a hearing loss. If a hearing loss is present, annual hearing evaluations are advised to monitor changes and ensure proper treatment. Regular hearing checks allow changes to be identified early and help support long-term hearing and brain health. Especially if you are currently wearing older hearing aids (3 years or more).
How do I know if I need a hearing evaluation?
If you’re asking this question, it’s often a sign that a hearing evaluation is a good idea.
If you're noticing yourself asking people to repeat themselves, having trouble following conversations in noisy environments, or finding yourself turning the TV or phone volume up higher than others prefer, these may be signs of hearing changes. You might also notice increased listening fatigue or difficulty understanding certain voices. A hearing test provides clear insight into what you’re experiencing and helps determine whether treatment would be beneficial.
What if I don’t think my hearing loss is bad enough OR why can't I wait until it gets worse to do something?
That’s a great question. There are two things to consider: hearing loss and clarity loss. While your hearing loss may feel mild, clarity loss is often the bigger concern.
Clarity loss is caused by auditory deprivation, which occurs when the brain doesn’t receive clear sound for extended periods of time. Even if your hearing levels don’t significantly worsen, the brain’s ability to process speech can decline, making words harder to understand. Over time, this loss of clarity can become permanent. For example, speech understanding that may be around 92% today could drop to 72% if hearing loss goes untreated — and that lost clarity may not be fully regained later.
Procrastination is the biggest risk, even with mild hearing loss. Untreated hearing loss can make conversations more exhausting, cause you to miss important details, and lead to frustration or social withdrawal. An early hearing evaluation helps preserve clarity, supports brain health, and allows you to take a proactive approach to protecting your hearing and overall quality of life.
What is the difference between OTC hearing aids and prescribed hearing aids?
OTC hearing aids are designed as one-size-fits-most devices and are NOT based on a professional diagnosis. Prescribed hearing aids are customized using advanced testing, real-ear measurements, and professional programming to match your exact hearing loss. That level of precision is not possible with OTC devices.
Can hearing aids help with tinnitus?
In many cases, yes. About 90% of people with tinnitus also have hearing loss, and treating hearing loss often reduces tinnitus symptoms.
Are hearing aids noticeable?
Modern hearing aids are designed to be discreet, lightweight, and comfortable. Many styles sit behind the ear or inside the ear canal and are barely noticeable during everyday interactions. They’re available in natural skin tones and low-profile designs that blend in seamlessly, allowing you to hear clearly without drawing attention to the device. You could be wearing your hearing aids for 6 months to a year before anyone notices you are wearing a hearing aid (unless you tell them). And! Untreated hearing loss is much more noticeable than wearing a hearing aid.
What kind of follow-up care is included?
Follow-up care is an essential part of successful hearing treatment. Your care includes scheduled follow-up appointments, fine-tuning adjustments to improve comfort and clarity, and ongoing support as your hearing needs change. We take the time to ensure your hearing aids continue to perform well in real-life situations, not just on day one, so you feel confident and supported long-term.
