It can be easily adjusted sounds to obtain your optimal listening experience by using your iPhone mic and headphones. By using this app to watch TV or conversations in a noisy environment, you will learn how assisted hearing could help. You can also make the simulated experience of hearing loss.

All sounds are a combination of frequencies, and our voices produce sounds at different frequencies. As you get older it is natural to have difficulties with hearing in the higher frequency spectrum. The other hearing difficulties are often quite specific, so you may need to experiment to find the appropriate compensation to you.

"Listening Tuner" helps you to hear better by using our proprietary digital processing technology, Graphic Equalizer, Preset-Equalizer, Noise Suppressor and more sounds control functions. In addition, On RePlay function, you can playback the sound you missed listen on just before 15 seconds.
