Two questions if someone can help?

1). I'm interested in these headphones to take mobile / bluetooth calls (besides music) but I need to know for certain if they will play back my own voice in my ears when I'm talking on a call. This is important as it's difficult to talk to someone if your own voice is isolated from your ears due to full covering headphones. All you hear is a low mumble from your voice and it's very fatiguing. Some other headphone manufacturers such as Bose and Beats have implemented this for their bluetooth headphones. Also if these do not but there are other Sony Bluetooth headphones that support this feature can you please tell me the models?

2). I've heard that this model is being retired. Is this true and if so what is the replacement and when are they due to be released?

Thanks for your help.
