Initially I was looking around for a good set of headphones to use with my K750. The supplied ones were just not confortable, and the local SE dealers failed to fetch me an original HPM-70, even though I was ready to pay in advance.
Ideas come from an idle mind - remember Newton? Well, I just came across a damaged set of original K750 headphones, and decided to put it to good use. And here's what I did......
Er.....This is the NOT what I have created, this is the original SE stuff to show you what I was trying to achieve.
For creating the cable, I used one of these.....
And after a lot of experimentations and soldering/De-soldering, I finally achieved this...........
But the above contraption still had some exposed wires around, and had the risk of damaging the wiring/contacts. So I used some epoxy adhesive to Finally achieve THIS.........My own HPM-XX!!
I know it looks too crude, but hey, it absolutely rocks with my woofer system! I am still on the lookout for a pair of *good* earphones for testing - my existing Philips earphones aren't much good anyway, and the list time I used them was 2 yrs back!.
All the more, the entire setup cost be barely a few cents. (To be very precise, it cost me around barely 5 Rupees here in India, equivalent to 10 cents!!!

Good work, but perhaps a little less epoxy adhesive, and a proper shape would have done a lot to improve it's looks

Hmmmm.....had been prowling around electronics shops, and came across this one today - a stereo socket with a well-built housing.
If you see the pics of the original contraption, it was all crude and ugly - and I was rarely using it.
So now immediately I set to work, and I've modified my cable to fit the new socket. Also, I cut my wire short, making a good-looking as well as a very wearable device - this:
Pretty much resemples the original thing, doesn't it? BTW all I need is an orange Walkman logo/sticker!!!
[EDIT] : Hey!! just noticed....this is my 50th Post - hit a halfcentury here on Esato!!!

@Kamikaze, I got mine free of cost from a distributor and you can get one too if you have deep contacts with the distributors. The service centre guys are tough nuts to crack, though u may like to try your luck.

may i ask, where's the mic in that jack? were you able to make calls using that jack? like in the real walkman jack, it has the mic in the jack, so you can still make calls and the other party will be able to hear you... i'm interested in making one too, for my current phone, and i don't want to change my headset at the expense of losing the mic... (hope i made my question clear)

@VRL29, I got ur qn.
I don't have the mic added in yet, and to talk to someone, i need to take the cable off. As of now, I can only hear the caller thru my earphones, but he can't hear me thru the jack.
Technically it's less than a minute's work and very much possible to embed a mic in the jack. There are 5 wires in all, of which 3 are used for the stereo/earpiece, and the remaining 2 wires that are unused, are for the mic. The mic is also there with me and all I need to do is to solder them on to the wires - and it's done.
There are some qns in my mind though:
* Where is the mic in this thing? It's the original accessory offered for sale on some website.
http://www.esato.com/board/img.php?id=49041
* Where exactly is the mic of the HPM-70? Is it inside the pod where the 3.5 pin is connected? But that's so far from my mouth and very close to the phone, right?
* If the mic will be so far from my mouth, how will my voice reach the mic? How is it in the real HPM-70?
* So if the mic is embedded in the jack, i have to keep the phone in my shirt pockets at all times and can never keep the jack and the phone in my pant pockets, right?
I haven't actually seen the HPM-70's layout. Does anyone have a detailed diagram/pic? W800 user please post some detailed images.
Also, anyone having the original accessory (the one inthe pic shown) may kindly shed some light on the layout of their device.
Thanks & Regards
BG

yes, the mic is in the jack itself (if you'll see the pic, there is a vertical hole near the "walkman" logo). my GF has a W550, and i've seen the cable with the mic itself...
as for your query, you have a point there... since the mic is "far from your mouth, how can the caller hear you if the mic is in your pocket? that's also one of my questions in the said design, and my "observation" on the matter is that  have strong microphones; they can capture sounds that are at least a feet away(at least that's what i noticed when i'm on a call)...
