Southwing sa505 bluetooth with Meizu M8 problem

Hello I bought Southwing Sa505 bluetooth headset to use with Meizu M8, but there is stridulation in sound with music and with phone talking.

Headset works great with my friend's iPhone, but not with my Meizu M8SE
Also other headsets with bluetooth works fine with Meizu

Now with details:
my firmware is 0.9.6.9, I also tried with 0.9.6.12 and 0.9.3.9

nothing works. It connects perfectly but sound is like it is consistently interrupting. When watching video using this headset, sound comes after the video and the audio and video interleaving increases in time.

What do you propose?

Please help!!!

maybe it helps if you set a com port with bt com
you can find it here in the download section

I downloaded and installed it. But nothing changed!

Any more ideas?
