While BTunes is Connected to Two Devices I Get Bad Signal Quality/A Large Amount of Signal Dropout

When BTunes is connected to two devices at once sometimes they can interfere with each other making signal quality much worse than what it should be. 

To resolve this issue disconnect BTunes from the device you are not using to stream audio at the time. For small transmitters simply turn off that transmitter. For phones/tablets/PCs go to the bluetooth options, look for the BTunes under devices and select disconnect. This will disconnect that device from BTunes

    This sounds like a bug not a fix.

    Many times when I'm connected to my computer and my phone at the same time and I get a phone call, the call quality is very choppy and digitized.

    Hello Domonic, 

    This is a case of different bluetooth profiles being used by your computer/phone for different processes. When you are streaming music the computer/phone uses the A2DP (Advanced Audio Distribution Profile) profile of bluetooth to send the signal to BTunes. This profile is specifically made for music playback and gives high quality audio info for BTunes to receive and play on your headphones.

    However, when you are on a phone call or using the microphone to talk in a game the computer switches to the HFP (hands free profile) of bluetooth and this profile carries significantly lower quality audio information to BTunes and also only carries Mono audio. With usage of this profile sound quality will be bad with any bluetooth receivers so while this profile is effective for making calls it is not good with sending high quality audio.

    I can understand the different data transfer modes and that makes sense. This is not just lower quality audio, this is unusable audio. I can't make out what the person on the phone call is saying.

    Hello 

    I have exactly the same problem as the one described by Domonic... furthermore when I use another BT transmitter ( samsung) with the same headphone QC25 I do not have these distorsions when making a call

    I am not sure if that resolution you gave is a fix, its more of an annoyance.  I have to turn this thing on and off a lot.. it causes some big lag, not to mention actualy causes my computer to get sluggish if stuttering on a video.  is there an update, firmware or something?

    I also have this issue when connected to my PC and mobile phone simultaneously. Disconnecting one device after answering a call is not a practical solution. Have there been any updates to this issue?

    Bluetooth technology is mainly a point-to-point technology. Qualcomm extends it with its own chip to make it possible to connect one device (the BTunes) with two other devices (transmitting). We use Qualcomm's technology in the BTunes. However, the Qualcomm's technology can't work with two devices simultaneously, although they can connect with two devices simultaneously. It works it this way. 1) When you turn on the BTunes, it connects with two devices. It's ready to work with either one of the devices. 2) Let's say that you listen to or interact with one device, to work with the second device, you need to pause/stop playing with the first device (note, it's not to disconnect with the first device), there's a time delay, up to 30 seconds or so, when it's ready to work with the second device. 3) When you stop/pause with the second device, up to about 30 seconds or so, the BTunes is ready to work with the first device.  Basically, as you switch between those two devices, it's not instant. It's the limitation of the Qualcomm technology.
