electronics fedi i need your help.
so i have these headphones that have been broken for years now and want to see if i can repair them. the issue as far as i've been able to tell is these solder joints (pictured) are broken and not properly connecting.
how hard would it be for someone who has never even breathed in the same room as a soldering iron to go about this? can i just buy the cheapest junk soldering iron and solder online and make it work? what do i need to know before attempting this?
(before you pledge allegiance to your favorite solder brand or send amazon US links my way let me clarify i am reasonably confident none of the brand names you recommend will either be available to buy over here or as cheap as you expect)
