I have had a Creative WP-350 Headset for a while, and the bluetooth and headphone quality are great. My problem is that I can't use the headphones and microphone at the same time without having the headphones default to "telephone quality" audio.
This is the screenshot of the Windows Playback Devices:
If I select the Bluetooth Audio Renderer as the main device, I get normal audio quality, but whenever I use the microphone, the audio cuts out. If I select the Bluetooth Hands-Free Audio as the main device, I get "Telephone Quality" audio and the mic works. See below for a screenshot of the audio quality when using the mic:
When I use my phone with the headset, I get the audio and the mic at the same time with the good quality, so I don't think it's a hardware problem. Does anyone know of a software solution to this problem?
