My experience with this sony hesdset is not soo good .I purchased sony headset five months ago .The built quality of this headset was really very good . The output noise was pretty good .
The problem was that
Example : When I plugged the headset in lenovo device so it worked well
But I faced a lot of issues with moto and gionee devices.
-The wire was bit thin .
-The output was good but there was no bass in the headset.
So my experience was not so good .
