K&B Audio Happy Sound Guarantee



Send line level audio up to 100m using inexpensive CAT5 cable. We have tested these using the headphone jack from an iphone and also using the line output from a CD player as a source. We blind tested between using a 100m CAT5 cable with these adaptors and using a 1m interconnect and we could not hear any difference. Using a signal generator there is approximately a 4db roll off at around 19Khz. In short, they are cheap but they work extremely well!

Note they are intended for point to point use with a single CAT5 cable ONLY. They are not able to be connected to a LAN or any type of network adaptor/splitter/hub/switcher

For reference, the pins used on the CAT5 socket for the C5AUDIO adapters are as follows:

  • TIP is wired to pin 8
  • RING is wired to pins 5 & 6
  • GROUND is wired to pin 7


  • Colour: Black
  • Sold as Pair
  • Female Cat5 / Cat6 to Male 3.5mm stereo jack
  • Upto 100m
