can a headphone cable be too long?

Question

Just put our Tv on the wall in the bedroom, and I use headphones at night if the wife is asleep, however I sometimes fall asleep with them on and am worried that our five year will run in in the morning trip over the wire or pull the tv off the wall. The headphones have a 6 metre cable , but when I ran it along the floor round the walls, it was just a little short, so I bought an extension wire. Now all the wire is hidden away nicely but when I listen at night, the sound keeps fading in and out. The extension wire was 3 metres. Could it just be too long, or could it be interference from the power cable, or aerial cable as it runs alongside these in trunking?

Answer 1

The longer the cable, the more the quality of the sound deteriorates. 9 metres of cable would probably mean the highest and lowest notes are a bit quieter, but unless you're a music expert, you're unlikely to notice the difference.

Intereference from the power cable would be a constant 100Hz hum. The aerial cable won't make any difference. Your problem is more likely to be a poor connection where the two cables join. (We can cram 100 million transistors onto a 1mm square chip, but no-one's managed to come up with a satisfactory inline jack socket).

Answer 2

Do what l did - get wireless headphoes, you get a transmitter that plugs into the headphone socket on your tv, and a set of headphones, no wires!! Cost less than £20 too!

Get some remote headphones. No wires. I've got some and you can use them all over the house and even in the garden.
