No bother - adaptors by and large are rubbish, I have a set of 'not insignificantly expensive' headphones from one of the top manufacturers and the 6mm adaptor that came with that was rubbish so I cut the plug off and soldered my own 6mm on.
Sometimes you get lucky, another issue I've found with them is that sometimes the extra mass that they add can open up the contacts inside the plug too.
It's a nice easy fix, I'd spend a few of whichever is your favoured currency unit on a formed cable rather than use adaptors, you can get RCA to 3.5mm TRS very cheaply, even for good quality cables so might be worth an investment.
Glad it's sorted for you!
