Hey, My newest app is Amplify and its free. Here is the link followed by the description. Amplify App Store Link. Amplify will listen to audio through the earbuds headset with a mic and amplify it to the earbuds. If you talk into the mic you will hear your voice and know what you sound like. This applies to singing along with a song or hearing yourself for a speech. It is also a partial hearing aid. All the audio goes through the earbud headset with a mic. You simply flip the toggle switch to turn it on and flip the toggle switch again to turn it off. Very simple, easy, and fun to use. - Matt
