Other than you are running in low power mode and you are dropping half of your packets, that works fine.
This is going even more farther from headphones, but OK :) BT2.0 is 3Mb/s in theory. More than 2Mb/s in practice. That's twice more than one needs for uncompressed 16 48 stereo. And _original_ 802.11 is not really Wi-Fi (802.11 legacy was released around 1997, Wi-Fi Alliance founded around 1999).
