Query: "So called" Sennheiser Earbuds

I'm sure if these were an authentic pair of Sennheiser earbuds, they would be great. What I received was a $5 knock off. Be careful who you purchase an item from. If it sounds too good to be true, it probably is. The pair I received are junk. I tried to leave negative feedback for the merchant but removed it for editing and was unable to rewrite my feedback. I contacted Amazon about resetting the option for me to leave feedback for the merchant and haven't heard anything back. I also wrote the merchant an email and they didn't get back to me yet either. Junk.
