They're not overly hard to make, a bit time consuming at first, but not terribly complicated. Just don't get too frustrated if the first one turns out as an abomination. :)
When soldering the Sennheiser connectors, be careful. It is stupid easy to heat the pins up enough to start melting the plastic housing. I'm normally a SAC305 lead-free solder kinda guy, but for headphone cables I generally use the leaded Cardas quad eutectic silver solder (may not be the best price) because it doesn't require as much heat to flow.
I find that doing 4 (or 8) strands braided works rather well. Just put one (or two) strands of wire in four paracord sheaths, and do a flat braid. L+, L-, R+, R- each with their own paracord.
You can either buy a boot/pants to split the cable, or just use heatshrink tube. I tend to use the type of heat shrink with glue.
Here are some example photos of a cable I made a few years back:
BelCantoThe price for these cables is too high, but modding/aftermarket components for hifi gear can often be expensive and its not uncommon to spend nearly as much on supporting components as you do the hardware itself. Its not like this is the only option for replacement cables, and most people buying this are probably going for balanced which is a luxury.
Alternatively, buy the official HD650 cable from Sennheiser for ~$11 + a soldering iron and whatever connector you want, and it would still be cheaper than this. Plus, you would learn a new skill in the process.
bdingI was looking for things to learn in the spring of 2020 and soldering was at the top of my list. Certainly glad I learned and I am now quite good at it. I can pretty much desolder and solder the PCBs in an xbox controller, mistake free, in a few minutes. I've taken out stock cables and added detachable cables in about 5 pairs of headphones.
That said, I dont think this is good advice. I wouldnt recommend learning how to solder just so you can save money on this particular cable. Learn because you want to learn how to solder. You likely lose a lot of money before you start saving. Even if you can make it work on your first, or first couple of tries, its probably not going to be a good job. Before you even start a job youre gonna need to buy a bad soldering iron for $12 bucks that plugs right into the wall, plus some solder and flux for like another 5 or 10 bucks. then youre gonna realize you didnt buy the right solder and you should have bought a better soldering iron. then youll buy a $60 kit with a knob for heat control and a solder sucker for $10 to clean up your mistakes. add in some clamps and a magnifier and im sure there are some wizards out there that can work wonders with that setup, but by then you'll probably have recognized that heat control is very important and certain jobs are best done with certain tips. Thats when you buy a station for over $150 with a screen that allows you to control temps down to the degree and a bunch of tips for different applications.
if youre anything like me youll also probably have fried your fair share of components used for your projects. e.g. if you plan on making your own cable or making a DIY scuff controller, while learning on the fly, my best advice to you all is to buy enough hardware to make two or three of your desired end-product.
I'd buy the Senn 2.5mm if it was offered in a really short length like 1.5", so I could use it with a BT receiver and connect it to an extension for desk use... I've had cables like that made for some of my other stuff but not my 6XX, heh.
StopBadDropsThat's still way longer than I'm looking for, heh, but thanks... About 0.5m would be ideal for use with a clip on receiver when I'm not at my desk setup, probably have to go custom for that which is what I did for my IEM & ZMF.
I don’t enjoy criticizing, but the consistency Drop has displayed when listing products with incomplete specs is plumb damned amazing. Listing cables with no measurements, dac/amp combo with no specs for the output power, etc. Members here are supplying information Drop should include without thought.
