What follows is an overview of each of the main types of hearing aids...

The first type of hearing aid is one that fits directly into the canal of your ear. Being so small, and being hidden inside the ear means that it is hardly visible at all. The downside of it being so small though is that it is very difficult to make any adjustments to it. A second option is a hearing aid which sits partly inside the canal of your ear and partly outside of it. People you talk to probably will not notice it, even though it is a little bigger than the first type. The battery life is reasonable, but still not as long as you would want it to be.

Your third option is a hearing aid that is worn in the canal of the outer ear. If your hearing is very bad then one of these is advisable over the first two types of hearing aids because these ones typically have a bigger microphone incorporated. They are prone to picking up unwanted background noise, so getting it properly, and regularly, adjusted is important.

The final type of hearing aid is one which is attached behind your ear. Though the bulk of them sits behind the ear, they also have a component that fits inside ear. These are the most customizable, but are also the most visible. They are a good choice, so long as you do not mind it being obvious that you are wearing a hearing aid.

If you cannot decide which hearing aid will be best for you, then ask manufacturers if they offer trial periods for their products. You can also ask your doctor if they can recommend one to you.
