Useless Product.

AnthonyP from Westchester NY on 12/27/2012

Crutchfield Customer Review (What's this?)

I did not head the warning of other users and bought this product to connect my Sony CD changer to my Onkyo receiver. The round ends did not stay in the optical ports of either product. To inexpensive to return it and not long enough to use it to skip rope. Crutchfield should ditch this useless product> I have not seen any ports that are round in this country they are either square or Toslink why then sell it?



slip out easily

Crutchfield Customer Review (What's this?)

dont like these, they are round shape and come out easily while moving box around. prefer the D shaped ends specific to toslink.



What I expected

Dan from North Babylon, NY on 1/8/2010

I did not see that review before I bought this product. In any case, once i discovered the round connectors, i was not sure if they would work. On my setup the cable worked fine. One end is plugged into my Sony receiver and the other into my high-def set-top box. The sound comes through fine, and even on the dolby 5.1 setting, the sound still sounds good. I compared it to my Monster optical cable, and the sounds quality is comparable (for my use). Don't be frightened by the round connectors though, they are designed to fit into the standard toslink optical port, but they rotate once they've snapped in (actually slightly helpful during setup).



I can't believe Crutchfield sells this product

Crutchfield Customer Review (What's this?)

A round peg in a square hole. That is what the arista optical cable is. Optical ports are (mostly) square. This cable has round plugs, it would not stay in the optical ports of 3 different components (Dell TV, Sony BlueRay player and Pioneer amplifier).
