Hearing aids come in various styles and features, so it’s essential to understand the different features of each style before you invest in one. These features include directional microphones, direct audio input, rechargeable batteries, etc. Read on to find out which one is right for you.

Directional microphones

Directivity is a critical component of hearing aid technology. The microphones inside hearing aids must have the same directional properties. These characteristics can be achieved in two ways. One is by incorporating two microphones into a single device, while the other uses a combination of both. One way is to combine two directional microphones into one. Then, the hearing aid will be able to provide a directional pattern.

Adaptive directionality is similar to fixed directional systems but may allow the user to adjust the frequency range of the directional microphones manually. Some hearing aids offer fixed directional microphone settings and frequency-specific adaptive directional microphone settings, and these settings can be manually or automatically adjusted. However, these additional features may not always be beneficial to all patients. If you consider purchasing a hearing aid, it is crucial to determine what kind of directional microphone is best for you.

Rechargeable batteries

Disposable batteries are the preferred choice of many users because they provide general reliability and are easily accessible from local stores. However, they require weekly replacement and are often prone to damage. To enhance your hearing aid’s longevity, it is best to recharge it regularly. Keep the battery compartment dry and clean to prevent moisture from affecting the battery. Similarly, store your hearing aid’s batteries in a cool, dry place to prolong their lifespan.

Rechargeable batteries for hearing aids are becoming increasingly popular. They’re convenient, low-maintenance, and more eco-friendly than ever before. 

Direct audio input

Hearing aids with Direct Audio Input can bypass the microphone used by conventional acoustic devices, resulting in a better audio signal. People who use their cell phones near EMI sources often need this feature. Select behind-the-ear hearing aids have this feature. Direct audio input is not possible in all hearing aid models, however. The wires connecting the hearing aid to the audio source must be shielded so that they do not act as antennas for nearby radio transmitters.

Another alternative for direct audio input is a wireless headset. These products consist of a microphone and a receiver that the user wears. The latter is a headset worn over the ear or neck, and the microphone receives the signal via invisible IR light waves and transmits it to the receiver. Those wearing wireless headsets can receive the sound through a neckloop or silhouette. 


One of the best ways to maximize your comfort with hearing aids is to get custom-made ones. Custom-made hearing aids are more comfortable than store-bought models, and they allow you to move your jaw while wearing them. You may also get adjustments to accommodate your glasses. And most RICs come with rechargeable batteries.


In addition to the wearer’s lifestyle and environmental conditions, the type of hearing aid used can also affect the durability of a device. ITE and behind-the-ear styles of hearing aids tend to have a longer life span due to more electronic components in the ear canal. The use of a specialized cleaning solution for hearing aids can also help extend the life of a device.

Hearing aids are usually made of various materials, including plastic and silicone, and they are vulnerable to damage from moisture, water, and other substances. While most modern hearing aids are made with protective nano coatings that prevent water, dust, and moisture from entering the device, it is still important to treat them gently. It will help avoid damage caused by accidental drops and prevent the device from losing its function. When considering durability, it is essential to look for a product designed to withstand everyday use.

In addition to these factors, routine care is essential for prolonging the life of hearing aids. Audiologists can recommend dehumidifying products for the hearing aids to remove excess moisture from the device. These products can be purchased at a local hearing aid store or online. Moreover, they can also be used in humid environments. Cleaning hearing aids can also increase the device’s durability. In addition to routine care, hearing aids should be cleaned every four to six months by audiologists.
