Are these CX300-II's worth fixing?

post #1 of 9
Thread Starter 
I had, until last night, a perfectly working set of Sennheiser CX300 in-ear headphones. Due to my own stupidity, the input jack got snapped off and they are now useless. Would it be worth it to try finding a replacement jack say from Radio Shack and solder it on? I fear that the sound quality would be lessened because I'm ok with a soldering iron at best plus the quality of the new jack may not be up to par with what was originally included.

If it would be better to throw these used and abused headphones into the trash bin then I'd like some suggestions for a new pair (preferably in-ear) for under $100.

If you make good soldering joints it should sound just like the original plug. Heres a really cheap and decent jack for under $2 shipped:

They have good ones at radioshack too. But they aren't over priced. Radioshack is a store with overhead. I got a nice gold plated 6.3mm jack there for 5 bucks after tax. Online it would have been like 4 bucks. I certainly don't mind giving the extra dollar to actually buy it instead of waiting for shipping.

For it to be over priced, it has to be like 12 bucks like what best buy charges.

I feel like Radio Shack prices vary depending on the area, I live in SF which is arguably one of the most expensive places. Will stop by a local shop and see whether I can find what you're talking about.

If I were to buy replacement buds/headphones the bass would have to be of the same quality or better. I listen to a lot of electronic music and metal (kind of makes it hard), plus play BF3, The split between the two is about 60/40 (music/games). The most common problem that I've run into with over ear headphones is that they start hurting my ears from the pressure after about 20 minutes of wear, although I haven't really tried many high end sets.

Again the price is preferably below $100 but I'd be willing to spend a bit more if the quality upgrade is significant enough. Keep in mind that I'm currently using onboard sound with plans to build a new rig with a discrete sound card probably a year from now.

So I got a new headphone jack then proceeded to strip the headphone wire on the headphones which resulted in this:




Can someone please explain which wires go where? This is my first rodeo as far as soldering headphone jacks goes. I assume red (positive) goes to the middle length post, red/green (negative) goes to the short one, and copper (ground?) goes to the super long one but what about the 4th green (no idea what this one is, positive for the 2nd channel?) wire?

On a side note, these wires are TINY and have fiber insulation, will solder hurt them at all?

With the help of Google, I was able to find instruction on setting things up correctly. The trick was to burn the coating off the wires so that they would make proper contact with the posts.

Color codes are as follows:

red: right channel positive
copper: right channel ground
red/green: left channel positive
green: left channel ground

Here's a youtube video I used as reference in case anyone ever runs into this problem.

I had to join the green one with the red/green one in order to make the sound work correctly on both earphones.
