Amplifier

I needed to hook up headphones to my Samsung Ultra TV and wasn't sure if this was the answer but it works perfect and more than what I expected at a nice price.

Product OK, Vendor Sucks.

Not bad for something this inexpensive. However, I needed them on a deadline and paid for expedited shipping and the supplier did not ship them correctly. While they did refund the difference in shipping charges, it wasn't easy to do because of the HORRENDOUS customer service and a voice mail box that is always full.
