A week ago I sniped a pair of broken ER4XRs on eBay for 80€. The seller said that one side didn't play and I was hoping that a simple cable swap would fix the issue. Sadly, it wasn't the cable's fault and instead the driver's. With my multimeter I measured 45 ohm for the working driver and 90...

I was wondering if it would be possible to create a custom pair ofiems that are waterproof to swim with. Yes I know that's insane. The Knowles RAF and RAB drivers are listed as waterproof but what other drivers could I use? Would I need to put wax over the connectors? would the filters be safe?
