Earphone jack connection

My earphone jack doesn’t make a tight enough connection with my jack. Is there a way to open up the case and tweak the jack contacts?

Much obliged for any help in this matter.

Thank you for that post!   I was getting ready to send mine back… it would cut out and would jiggle lose.  I hated pushing it in so hard, afraid I’d damage something.  You did it right!   Thanks!   Works great now with my little X-mini speakers that are great also!
