Bad sound through bluetooth headphones

I have a problem with the sound quality of a pair of Acoustic CHP600BT Solutions Bluetooth Headphones - Black.

When I connect these headphones to my phone (Samsung S2 plus), the sound quality is perfect, but when connecting to my laptop the sound quality is bad with static.

I use Windows 7 Ultimate. I reinstalled all drivers and searched the problem on Google, but found nothing.

I had the EXACT same problem and fixed it from the above comment like this:

1. You have to uncheck “Handsfree Telephony” from the “Services” setting on your Bluetooth device → “Control Panel” → “Hardware and Sound” → “Devices and Printers”.  Select your device and right-click, open “Properties”, then go to the “Services” tab and uncheck “Handsfree Telephony”.  I just fixed it like that.

   This works on Windows 7 and Windows 10.

   

2. Mark it as your default device in “Control Panel” → “Hardware and Sound” → “Change system sounds” → “Playback”.  (It may be good enough to go to “Control Panel” → “Hardware and Sound” → “Sound”.)  Select your Bluetooth device and select set defaults.

   

I just ran into this issue, turns out I had two profiles, Hands Free and Stereo, I was using hands free, changed to stereo and this fixed the issue:

At random times when I connected my bluetooth headset (on Windows 7), the sound would get really bad.

After extensive research on Google, I found out that this seems to be because the Bluetooth protocol as it is right now does not provide sufficient bandwidth for the headset to use the microphone and high quality audio at the same time. This could be consistently proven when trying to use Skype with my bluetooth headset functioning as a microphone and audio output at the same time. The audio would get crappy 100% of the time.

For some unknown reason, sometimes when I connected the headset to my computer, the sound would get horrible, even though I was not using its mic. The fix I found was to simply give up using the headset's mic altogether. To do so, I disabled the bluetooth services for everything other than the audio output. This is how I've done it:

1. Go to Windows' devices
2. Find your headset, right-click it and select "Properties"
3. Go to the "Services" tab and deselect everything but "Audio Sink" (with this, I believe we are disabling all bluetooth drivers but the audio driver, making no other item mess with the bandwidth - beware, if something you'd expect from the headset stops working, it could be because of this)
4. Reconnect your headset (not 100% sure this is necessary, but it might be)

The steps described above worked for me, but I don't have enough knowledge to state that they should work for others. I hope they do. Good luck!
