Hi ssgcarney
Your LG HBM-730 can be found
HERE on LG's Web Site (North America)
You may be able to order a replacement from LG. You can find LG's Customer Care page w/ support contact info.
HERE
eBay has a lot of LG HBM-730 Ear Hooks up for auction. You can find my search results on "LG HBM-730 Ear Hook"
HERE.
I didn't have much luck finding them anywhere else. You can try your favorite Search Engine and perform a search on "LG HBM 730 Ear Hook" or "HBM 730 Ear Hook" or "HBM730 Ear Hook", etc.
