Xperia Z1 Bluetooth audio quality

[furreb]

I am experiencing a very bad audio quality through Bluetooth with my headset. On my other phone it's fine.. there is a lot of distortion and background noise.. anyone else have the same problem or know a way to fix it? Most likely Sony needs to make a fix for this in an updated firmware?

It's especially noticeable when listening to rock music.

I am also experienceing the same problem when listening with my Smart Wireless Headset Pro. Sound lot of distortion like speaker was damage. There is no distortion if play music video on YouTube or other music applications.
