Use a grounded outlet - no tingle. For balanced sound in earphones the plug must be fullt inserted. Is it? If it is then hardware fault. Buzzing also hardware fault. The dent - if it was not there on delivery then it's manmade.

Do a search. This has been an issue since the Ti-books. It's a grounding problem. Just add the extension cord that is wait for it grounded or simply stick the 2 part into a grounded outlet. It has even solved in some cases the buzzing through the headphone jack.
