Query: Wrong plug

Unfortunately, the plug on this headset has a collar on it that prevents usage on certain phones. After purchasing for roughly $10 and paying over $5 to ship, I now have a $16 piece of something I cannot use. Doesn't make any sense to pay to ship it back. MAKE SURE YOU KNOW IT FITS BEFORE ORDERING. THEY ARE NOT ALL THE SAME.
