Now Offering CAT5 Stereophone Cables!

Posted by Jeff Eggebraaten (Creator)

Thanks to everyone who expressed interest in Stereophone cables for Ethernet. It's a growing trend for modern custom built homes to be wired for Ethernet, but not telephone. The CAT5 Stereophone cable might be for you if your home is wired for Ethernet and;

  • Your internet comes to your home as a coaxial cable, and you use a wireless router for internet.
  • You're using the phone lines for internet (i.e. DSL, Dial-up).
  • You don't have a computer or care about the internet.
  • You're using a wireless receiver to steal internet from your neighbor's unsecured network.

To everyone who falls into one of the categories above, I introduce to you Cable E. Ethernet on one end, 3.5mm on the other, perfect for homes with unused Ethernet wiring.

      In answer to Ronson's question below:

      Please note that your speakers have to be self-powered, whether internally of via a stereo. It's the same idea as not being able to power band speakers off of an ipod.

      That being said, just plug an audio source into one Ethernet jack and your stereo or self-powered speakers into any other Ethernet jack. The audio signal will arrive at your stereo as if you had plugged it into the stereo directly.

      Awesome update. Since Ethernet has 4 pairs, would it be possible to run two separate audio feeds through the same cable or would that cause too much interference?

      I would love to be able to use the Ethernet port by my couch to power my two surround speakers.
