4 stars: I would give it 5 star. But there is a single problem. Can't play through Bluetooth headset. Please add this feature. This application really help me when I'm riding a motorcycle. Wearing helmet I still hear surrounding sound, horns through this application. Adding Bluetooth headset will boost the feature furthermore. Keep on Google. 💙
3 stars: Even when loaded on Pixel 4 App doesn't show until turned on in Accessibility setting. Want to use with Made for Android connection with my hearing aid but can't yet. Look forward to an upgrade. Hope it is announced. I have not used the program so this review should not be viewed as negative. Not my intention but necessary to send this message.
5 stars: First google app I rated 5 stars. BUT I have a request. In addition to sound amplifier, it should have noise cancellation as well. It can take input from mic and generate 'anti-waves' to cancel out the noise. No need for costly headphones. People can use it to sleep comfortably or study in noisy environments.
5 stars: this app even I gave it five stars because I'm sure some people have it working properly on their phone. It has never worked on my phone properly once. I have contacted support and still all it does is pop up to plug in your phone half of the time when I don't eat them I don't even have a pair. Your friend Michael's spinelli's family
4 stars: It is better than most of apps. If I use stereo mic. which is bigger than headphone's and can be attached ...
