What's the best Android app for using Bluetooth earbuds as hearing aids?

Hearing Aid App for Android is a practical solution for individuals seeking to enhance audio clarity through their mobile device. Developed by Firehawk, this app uses the phone's microphone to capture and amplify sounds, making it useful in scenarios like group conversations or watching TV. Key features include adjustable volume levels, noise reduction filters, and preset profiles for different environments such as restaurants or quiet rooms. Users report that the amplification is effective with wired headphones, but many highlight a recurring request for seamless Bluetooth earbud integration to improve mobility and convenience. For instance, someone in a noisy café could benefit from the app's sound enhancement, though the current limitation with wireless audio may require sticking to wired options. The interface is straightforward, with sliders for fine-tuning frequencies, and it supports real-time processing for immediate feedback. However, occasional latency issues have been noted in user reviews, particularly when switching between apps. Overall, while not a replacement for medical-grade devices, it serves well for casual hearing support, with future updates potentially addressing Bluetooth connectivity.
