Hello All, I have a set of over-the- ear earphones that I have been using daily for about three years. It is the JVC HA-RX300, and I got it cheap.
A few weeks ago, the wires became loose at the jack end and the signal became inconsistent.
Now, since they were cheap, and the fact that I am comfortable wearing them for 5+ hrs a day, I decided to try to fix them instead of just buying a new set of cans.
I went to Radio Shak and got a 1/8”(3.5mm) TRS Jack. I wanted a solderless one, and the rep gave me a screw on jack. Unfortunately, the wires still need to soldered and I do not own a soldering iron. So, as a temporary solution, I rigged up the headphones wires by wrapping them around the connectors and using electrical tape to hold in place.
This worked temporarily, however, if I move the wire too much some of the signal drops out. So I borrowed a soldering Iron form a co-worker, and plan on soldering the wires this weekend.
I have read up on soldering and think this is a good starting point; however, I have some questions.
I know that I need to clean the tip, and ‘tin’ it. I understand the basics of soldering circuit boards. However, how do I solder the copper headphone wires to the silver (steel,nickel?) TRS jack? The three headphone wires are the basic red, green, copper(-,+,ground).
1)Do I need to remove the colouring on the wires(if I burn them the colour comes off and the ends fray)
2)Do I need to tin the wire tips?
3)How do I get the most secure connection to the TRS Jack? Wrap the wire around, tie a knot with the wire through the hole, etc…?
Also, since I am only borrowing the soldering iron, I do plan on buying one. What should I be looking for, i.e. watts, iron vs gun, temperature reading, etc…?
Any and all help is appreciated.
By the by, I found these steps on the Internets, seems like good advice, but I am not sure I understand step #8. (http://www.ehow.com/how_7670935_make-headphone-cable.html)
