TV ears are a type of hearing aid that helps people with hearing loss to hear better. There are different types of TV ears, but they all work in basically the same way.
The TV ear consists of two parts: an earpiece that goes over the outer ear and a transmitter that sits on or near the television. The transmitter sends sound waves through the air to the earpiece, which then amplifies them so that the person wearing the TV ear can hear them better.
TV ears can be used with any type of television, including smart TVs. In order to use them with a smart TV, you will need to purchase a separate adapter that connects the transmitter to the audio output of the TV. Once you have done this, you will be able to adjust the volume and other settings on the transmitter in order to get the best sound quality possible.
