I've been researching this a bit, and getting a replacement for a lost earbud isn't hard from the usual places. It turns out, Samsung did not make it to easy from a user standpoint to be able to get them to work together. The two earbuds need to be able to talk to each other to form a stereo pair, and if you replace one, you'll be stuck pairing one at a time. Apparently, a Samsung service center can perform a sync process to get them to talk, and I am wondering if anyone has access to that software tool that can do that for us end users. I know Odin was the tool of choice for everything ROM related, is there such a thing for these earbuds? Thanks for any help you can provide!
