Outside phone call sound heard when wearing earbuds

[AC Question]

Newbie here.....

i hope i can explain this properly. lol i'm new to this phone... i noticed when i listen to music with my earbuds on, and the phone rings, it not only rings through the earbuds, but everyone around me can hear it also (as if i'm not even wearing earbuds).

is there a setting for this that i am missing? when i'm wearing the earbuds, i only want sound coming through them, no where else.

thanks for any help
