These cables allow you to connect your BeoLab 4 /4 PC speakers even if you do not have a Bang & Olufsen Audio and/or Video system. If you have any other model BeoLab speakers, and indeed the more recent B&O BeoLab speakers, with RJ45 'line' input sockets (e.g. BeoLab 17, 18, 19 & 20) we have special cables available for these loudspeakers as a different product.
