Need help recabling Philips Citiscape Uptown

post #1 of 10
Thread Starter 

I REALLY hated the in-line mic, so I tried to remove it. It wasn't quite as simple as removing it and connecting like colors, though, so I've just resorted to recabling. There are 4 wires in the stock cable, but it also had a mic and I'm not sure how that would affect it. It also only connects to one side. I'm wondering what cable and aux tip I should get that would be cheap (<$10) and durable. I'm thinking about a 26 awg cable, but I don't know if they come sleeved (I'm not interested in custom sleeving) or if I'd have to do that myself. I also don't know where I'd start for getting an aux connector that I could connect the cables to by myself. I can solder, so that's not a problem.

 

TL;DR:not sure how many wires I'd need in the cable and where to get an aux connector.

 

Here is a picture of the headphone side of the stock cable: http://imgur.com/FZljL

Hey, I'm also planning on recabling these headphones due to crazy channel imbalance caused by the volume slider.

 

Did you figure out which of the four exposed wires goes to what?

I am new to this forum.  I am interested to know if you have already figured out how to recable your Philips Uptown, as I want to buy the same headphone and do the similar modification – removing the mic and the volume control, and modifying to to detachable cable design similar to the Philips Fidelio L1.

 

In case you haven’t done it yet, I would like to offer my suggestion, based on my knowledge as a hobbyist in amplifier and loudspeaker building/repair for many years.  The 4 wires of your headphone are no difference from the 4 wires of a pair of loudspeaker cables.   In the case of hooking up a pair of loudspeakers to an amplifier, the most important thing is phasing – red terminal of the left loudspeaker is hooked up to the red terminal of the left channel of the amplifier,  black terminal of the left loudspeaker is hooked up to the black terminal of the left channel, so on and so forth, so that the diaphragms of the left and right loudspeakers would push and pull at the same time, and the sound waves, particularly of lower frequency, coming out from the 2 loudspeaker would not cancel each other and produce a hollow sound.

 

In case of your headphone, by following the color of each wire, you would be able to trace them to the 2 terminals of the left and right drivers.

 

The next thing is to combine 2 of the 4 wires.  Just pick any one wire first.  If that wire is connected to the LEFT terminal of one driver, combine that wire with the wire connected to the LEFT terminal of the other driver.  Connect this combined wire to the sleeve (or the “earth”) of the plug.  See the link: http://www.head-fi.org/t/510290/female-1-4-headphone-jack-need-help-identifying-left-right-posts for the parts of a plug.

 

To complete the job, simply connect the remaining wire of the left driver to the “tip” of the plug, and the remaining wire of the right driver to the ring of the plug.

 

Good luck.  Let me know the outcome.

I did end up finishing it with a cable from some old crap Sony headphones a friend didn't care about. The cable is hefty and has 2 sets of wires which simplified things, but there was a tiny board that seemed to just connect the wires to the speaker leads in the headphones, so I just took it out. I'm not sure of the effect it had, but I made an imgur album with all the pics from the mod: http://imgur.com/a/9nrc1

 

Hopefully this helps

I recabled some uptowns about a week ago.

 

I cheated though, I took them apart, pulled out the existing cable, and drilled a couple little holes in each side, then ran my new wires thougth the holes.

Anyone want to offer some advice as to how to crack them open? The pads don't seem removable, the rear does not show any obvious access.

You have to pull them apart and end up breaking the plastic that holds the two parts together inside. They're not fun to work with

They have different versions.  On my set, the pads just pulled off, so it was easy.  I remember reading that some versions do not have removable pads.

I managed to break the wire on my uptowns, and the pads do not pull off, but after I looked closely it looks like I can get into them with a couple of screws on the inside of the cups

When I find a small enough screwdriver I'll see if I can crack em open and update

Thanks guys. I've come back to this thread after recabling them.

 

Correct, 4 screws (sides, top and bottom). the pads are removable after the 4 screws are out.

 

Definately worth recabling, better bass extension (to my ears anyway). The issue is the cables are largely unaccessable, so I had to use a Y cable and make my own way in.

 

I'll be updating the Original review thread, few photos and me gushing over how much I like them here
