Bluetooth Speaker Booster by TS Systems is an Android app designed to enhance your Bluetooth speaker sound. This free app stores individual profiles depending on the connected Bluetooth audio device, so you don't have to switch your audio equalizer each time you connect to a different speaker, headset, or car. The app automatically informs you which device is currently connected and which profile is running.

The app comes with several profiles for different speaker types and also allows you to create custom equalizer profiles per device. You can also change the profile strength to apply to each device individually. Additionally, the app has a beta feature called Auto Volume, which allows you to set a default volume each time you reconnect with a device. This is useful if you connect to Bluetooth audio in your car or other devices that offer volume control.

When applying profiles, some users have reported that the audio output gets quieter. However, the app has a Loudness feature that compensates for this issue. You can also use the Volume Boost feature to enhance the output volume, but use it carefully as it can push the output beyond the specified range.

Overall, Bluetooth Speaker Booster is a useful app for anyone looking to enhance their Bluetooth speaker sound quality.
