How to decrease the volume during call in Xperia V?

[pets]

During call, the volume buttons increase and decrease the loudness, but it's not possible to decrease the volume less than certain volume (about 1/5-th of the volume bar). With normal phone speaker it's not a problem, but using headphones (Sony headphones MH750) that were included in the box, it is sometimes still too loud, especially listening a long conference calls. When I'm using same headphones to listen music with Walkman app, the volume level goes from zero to maximum as it should. But during the call the minimum is blocked. Is it a bug or "feature"? And how to get over of this?

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

That is correct that you cannot decrease the volume to zero when you are using the headset during a call. And unfortunately, it's nothing that you can change. But I will forward your feedback to relevant department.
