I bought two digital audio cables and a 3-way digital audio selector switch from eMaxland. The cables worked fine, no complaints, there.
The switch is so cheap it doesn't even have "Made In China" printed on it. I have several digital audio cables. Some of them don't fit into the switches ports. The cables I bought from emaxland fit fine. The switch didn't work. Rather, I should say only one of the three ports carried a signal from my components to my headphones. (PS3, Apple Mac Mini, headphones with mic) I contacted customer support and they offered to send a replacement. The switch is so cheap I didn't have to return the defective unit. Name 3 other products sold at Amazon where you don't have to return a defective product when getting a replacement. Replacement switch works. Shipping from US takes a long time. While waiting for my replacement I found this switch at another site for $9.99. For $47.99 you can get a local audio/video custom installer to get you a digital audio switch.
