cable munufacturing fault
Madam has a pair of Philips headphones, with which she listens to the telly
when I'm snoring. She complained that the right side was intermittently dead, so I had a look. At first I thought it was the little in-line volume control, but it wasn't as it turned out. Moving the (very long) cable slightly caused the fault to come and go. I ran the cable along the floor in a straight line and put books on it at intervals to prevent movement being transmitted along it. I wiggled each section until I found one where the fault occurred. Bit by bit I narrowed it down until I became certain that the fault was inside a section of cable only about 100mm long. This bit of cable looked and felt completely innocuous. Nevertheless I stripped the outer sheath off carefully. Inside were three very thin multistranded wires, each insulated with plastic. After only 40mm I found a 25mm section of one wire with no insulation. The bare length included a joint, made by twisting the two wires tightly together. This joint looked as if it should conduct without difficulty, but in fact moving it made the audio come and go. So is this what happens in wire factories? The roll of red comes to end half way though a run so someone starts a new one and just twists the end together? Blimey! Bill |

AW Obviously, a regrettable manufacturing fault! However, all headphones are made this way. I've often had trouble with wires breaking off at the jack. Unforutnately, if you try to solder on a new jack, it's almost impossible, thanks to those multistrand cables. Philips are one of the few consumer electronics groups left in Europe, and in fact have done quite well, after recovering from an earlier disaster.

So is I think you have a good case for getting a replacement on the grounds that its not fit for its intended use. Such joints are probably only there as a termporary job during manufacturing the wire, and should have been cut out and thrown away. Take a photo of the joint for a record, and in the first instance complain to the shop where you got it. And if they won't replace it send a letter to Philips. rusty |

Anyway, I tend to break a set about every 6 months - mainly by sleeping on them, but since they are 79p a set at the local shop this is no real problem. |
