In the source's own words
“The rendered audio is of lower quality (similar to that of a standard phone call) and mono.”
Bluetooth profile comparison, Unity Technologies, Unity Vivox developer guide, Android, n.d., Tradeoffs of using SCO or A2DP.
Open the original- What it measures
- The same section describes A2DP audio as high quality and stereo, so the switch to a voice connection is a trade in quality.
- What it does not show
- A developer description of the Bluetooth API for Vivox, not a measurement of any headset.
