expired 6 Feet 3.5mm Stereo Audio Cable - $0.89 - Free Shipping !
This was posted 1 year 1 month 3 days ago, and might be an out-dated deal
Thought I'd post this before they sell out again, got em the last time, handy since I don't have an fm transmitter and helps with extensions, etc…
Note these do not have gold plated tips, but 89c with free P/H more handy than not… ;)

- the malleability of the gold allows it form form better connections
- its corrosion resistant so I guess better connections for longer?I've been told its not electrical conductivity
http://en.wikipedia.org/wiki/Electrical_resistivity_and_cond...
shows that it loses out to even copper.
I believe this stuff is only relevant to analogue connections. For digital cables a signal is a signal. If the cable aint broke, and theres a signal, doesnt matter what its made of
+11 votesGold is mainly used for its corrosion resistance, but other factors come into play.
Electrical contacts, whether in a switch, a relay or a connector have to conduct an electrical signal without changing that signal. A layer of oxide on the contacts will cause resistance, which is a particular problem with low-voltage signals, as contact resistance is non-linear and can cause noticeable distortion of low-voltage signals like audio signals.
Gold doesn't oxidize, so it it a pretty good contact material for low-power (e.g. audio) contacts. Unfortunately it melts easily, so if you use it for high power, you run a high risk of contact arcing causing the contacts to weld together. Silver-nickel contacts are commonly used in relays for this reason, that material has a low chance of contact welding.
Mercury-wetted contacts are even better than gold, but as mercury vapour is toxic, you will only find mercury-wetted contacts in sealed devices, e.g relays. Even so, mercury-wetted contacts are rare, and only used for very demanding applications.

Some serious knowledge bombs being dropped here.
Thanks for that, I know i learnt something.

At current price its still cheap at $2, already have a 2metre spare one so didn't get one but these are always handy for HTPCs, plugging ipods into amps etc. Even have a small one at work I use to input music into my notebook from my ipod as my ipod internal speaker isn't that good.

Bought, Thanks!
Anyway what's the point of gold plated tips?
