A2DP Volume vs Noise Cancelling
Side-by-side comparison of two open source alternatives
A2DP Volume
Automatically adjusts the media volume on connect and resets it on disconnect. This is done so that stereo streaming audio can work properly. Intended primarily for car Bluetooth systems. It can read out text messages using Text To Speech (TTS) services while you are connected. Each paired Bluetooth device or virtual device (home dock, car dock, power connection, or headset plug) can be configured to your liking. There is a manual on the website. A secondary feature is the ability to capture location information so you can find where you left your car. The location can also be automatically captured when exiting Car Mode on your Android device and read by any app that understands GPS data.
Noise Cancelling
This app allows you to quickly turn off noise cancellation on Bose Noise Cancelling Headphones 700 (NC 700) and Bose QC 35 (QC35) headphones. It also allows a (less-useful) change of mode on Bose QC Earbuds and Bose QC 45 headphones (but not able to fully disable active noise cancellation on these devices). For example, the Bose Noise Cancelling Headphones 700 can cycle through noise cancellation presets, but these are on a scale from actively passing external sound through, to cancelling out external sound. In a very quiet room, any setting on this scale can result in an audible hiss, and you may not want any active pass-through/cancelling at all, but just the source sound. This app allows you to turn off noise cancellation, either in the app, or by adding a quick settings tile, or adding a single touch shortcut you can pin to your launcher. Noise cancelling will turn back on if you alter the noise control settings on the headphones, or when you next turn the headphones on.
