It is not an all sound amplifier. Doesn't work with built-in speakers. Viper4Android is better. Trying to enable it without headphones tells me it requires headphones. Five star review requires amplifying the built-in speakers. The name isn't even right. It should be, headphone sound amplifier.
On the Samsung Galaxy S22, this app does not recognize bluetooth-connected hearing aids as being headphones.
realy works great! My phone speakers & earphones sounds even louder & clearer now! Fast, easy setup & No Ads! Thanks
it works ok but to adjust for every song is a bit much i think for Pandora or any other music services out there
completely useless!! distorts the audio even when boosting just a little. I miss my Samsung Galaxy. they have better audio.
I know this one real well and it works very well when you had the life experience that I've had. sometimes our hearing isn't so good. still works. just not as good. anyway, touch is life. it will work though
Tried this, listening to tv. using wired, open back headphones. It seems that there is just enough latency to make the headphones sound conflict with the airborne speaker sound. Result - disappointing.
I tried it again and it works now. But doesn't work to select USB mic, only phone mic. pretty nice settings to adjust and volume and noise cancelation and frequencies boosted. no ads. unfortunately no way to record the audio as well.
New review: just tried this app for the 1st time in years and discovered it now works with Bluetooth devices like hearing aids. There is a slight delay but it's great for situations like hearing someone across a table in a noisy place. Great to see Google addressed the wired headphones only limitation especially since Pixel phones don't have a headphone jack and you have to use a special USB adapter to use wired devices - and who carries all that stuff with them... This app is now useful!
Noise reduction works! (Although I have yet in an extremely noisy environment.) There is a lag in bluetooth, but that's understandable because that's a hardware limitation. It's also acceptable when you just want to hear voices from far end of the table without reading their lips. with slight distortion - acceptable, though.
