The foam they came with at the moment.Smart talk is meant to work like that .audio goes to 0 volume whilst you are talking . A shame the music doesn't pause though .
Did u use the default foam tips they came with or something else.?
I think the smart talk thing should work by pausing the music or by lowering the volume, there's no point in keeping the music going at 0 volume. I hope they fix it, and yes the music should pause and I should have the option to touch the bud to return to the music if I stop chatting. There are a lot of options for the "ambient control" but I think they are messy and the touch controls are limited to those three set.
