post #151 of 2381
ohh no!

please someone help!

i just got my velour pads and the hd650 cable
the cable doesn't fit!!
it is to thick to go in the canal in the head band...
what to do?
the hd580/600 cable is thinner?

i want some cable to make these babes sound more mellow/smooth.
so now i send the hd650 cable back and get what replacement?

please someone help!

Quick fix? Try removing both cups, flipping them downwards, and putting them on again so that the cable entry is from the bottom. You'll lose the single-entry capability but at least you'll be able to taste what the cable offers.

At least I think you can do that.

That's what I read to: you have to flip the cups in order to plug the hd650 cable. Please provide feadback: does it work, how does it sound?

How are the velour pads? I have to admit that the standard pads are a little painfull when I use my hd25 too long. Does it change the sound?
post #154 of 2381
thanks for the response 3xo + ljs.
the velour pads feel better on my ears and lessen the clamping somewhat.
ljs have you tried opening the twin head band?
that also reduces the clamping force.
they look neat too
sound wise i can't say yet.

i read flipping the cups works and the connector plugs look the same...
(i don't want to rip open the bag the cable came in since i'm returning it.)
i liked the single-entry.
that's why i'm still hoping someone here knows which senn cable i can use.

You cannot replace the HD25 cable unless you flip the cups and do dual-entry. But it's worth it! The stock cable of the HD25-1 is it's biggest weakness. Better cable makes a HUGE difference with this headphone.
post #156 of 2381
then what is this?
if not a recable hd25 with the single-side entry...

hd600 cable, mh.
is that thinner?

Those with a nervous disposition, look away now...

I'm not sure I understand if you have or have not opened the cable bag. If you haven't how do you know you can't fit the cable? If you can wait 5 hours I can check when I get back home, I have a hd650 and the hd25.

Look on page 6 in this thread for ways to use non-hd25-cables on the hd25 (edit: and the second of the above pictures)

i did not oopen the bag.
i can see the size (thickness)difference...
and i tried pushing the cable in the groove with the plastic.
post #159 of 2381
If somebody else hasn't managed to answer your question I will try to fit my 650-cables on my hd25 when I get back from work and get back to you.
post #160 of 2381
thanks snejk.
would love to keep the hd25s single-side entry...
post #161 of 2381
Maybe the groove in the headband is only very slightly elastic and you might need a lot of force to force the cable in.
post #162 of 2381
Tried to fit the 650 cable in the hd25 headband now and I didn't manage to fit it in the groove. I don't feel comfortable with using more pressure than I did. Anybody else who has succeeded in fitting the 650 cable in the groove?

This is the HD580/600 replacement cable which goes for $16.80. Today it came in the mail. This cable will fit into the groove channel in the HD25-1 headband exactly where the original steel cable goes. It does not require flipping the driver cups, and it can be mounted single sided! In order to install it single-sided you must cut off the plastic retainer where the two leads go their separate ways and force them apart a further 4 cm or so. Since this cable was not designed for single-sided mounting, and both leads are exactly the same length, one side will end up with a loop of 25 cm extra wire, which needs to be coiled and taped out of the way. The little twin-screw clamp secures it to the right ear cup, just as with the stock steel cable. I don't have any after-market 580/600/650 cables for comparison, but sonically it's an immediate improvement over the stock steel cable, even before burn-in. The one feature I'm not happy about is that it terminates in a straight 3.5 plug, which is not as convenient for portable use at the 3.5 right-angle plug on the stock steel cable. If retaining the single-sided mount is important consideration to you, I'd say go for this cable. If you don't already have the velour pads, add that to your order and save some postage.

But I thought to myself: "What difference can it make? Probably some minor improvements".

So my first thoughts were that I rather get a new CD or two. But eventually curiosity got the better of me and I ordered the HD25-13 replacement cable #74532. A 3,5 meter cable with a nickel plated 1/4th plug from thomann.de



The cable was surprisingly cheap (A lot cheaper than the HD580 replacement cable or the standard steel cable and way cheaper than what my local senn dealer asked for it = €52 ! ) at €15,90.
I had to order for at least €25 and I ordered two pairs of HD414 pads along to mod, dye black and sell later in the for sale forums to get my €10 back

Now to the sound differences!
Much much bigger than I expected. The easiest way to explain it is that the steel cable sounds like steel. You got the feeling that the music had trouble getting trough. It got there eventually but had to leave a lot behind.

The soundstage never got through the steel but it does through the copper. Was the music before just on two places nexts to your ears, now it's wider. If you heard the sound only in the cups before you would now think that the cups have grown to be five times their size.

The sound is much fuller. The music sounds more rounded. And smoother. A more relaxed sound.
Where the music felt strained, like it had trouble reaching the driver it now flows straight into your ears.
The soundsignature of the HD25-1 doesn't really change much.

For ones I'm happy I let curiosity get the better of me.
this seems like a nice solution and it is ten euros cheaper then the first one...


here's a how to use the hd650 cable:

----------------------------------------------------------------------

Changing from the stock cable to the hd650 cable isn't too tough & honestly, for most of you, this tutorial is unnecessary. But it may be helpful for some, so here goes...

The stock configuration on the hd 25 has both left & right channel wires routed to the right ear cup. This results in unequal length wires since the left channel wire has to run the extra distance over the headband to reach the left ear cup. The headband has a groove that the wire fits snugly into...this groove is exposed when you pull the split-headband halves apart & the cable is easily removed from this groove.

The hd650 cable basically won't allow for the same configuration (at least it didn't for me). The 650 cable is designed to route the wires separately to each cup (with the split occurring somewhere near your sternum as you wear them). Subsequently, the extra length for routing the left channel wire over the headband isn't there. Yea, you could create the unequal length configuration with some modification, but even with that, the insulation on the 650 cable is significantly fatter than what's on the hd 25 cable. See picture here (the stock hd 25 cable is on the left):


In the end, I just couldn't squeeze the fatter 650 cable into the headband groove. I guess if you just had to retain the original hd 25 configuration, you could route the left channel wire over the headband & secure it with some cable ties (or some other method), but you'd also have to do some cutting & re-soldering to achieve the unequal length configuration...in the end, for me, it just made more sense to go with the hd650 arrangement.

So first, remove the stock cable. You'll have to remove the two screws at the right earcup, pull the left channel wire out of the groove, and remove the connectors from each earcup...just grasp the connector firmly, and pull them out. Note that one pin is slightly larger than the other (and the receptacle holes are sized differently)...be sure to match the pin/hole sizes when inserting the hd 650 cable (but if you've upgraded your 650 with an aftermarket cable, and you're performing this mod with the leftover stock 650 cable...you already knew this).

The stock configuration has the connectors inserting into the cups from the top side, but you do have two options:
Option 1: Keeping the stock configuration with connectors inserting from the top side
This configuration retains strain relief for the connectors and the cables, so while it requires a bit more work, it may be preferable...
If you decide to go this route, you'll find that the distance from the left/right cable split point (where the overmold is) to the connector ends is too short...without modification, you'd end up with the split point right under your chin. So, you'll have to remove the overmold at the split point & pull the left & right cable halves apart to create some extra length between the split point & the connector ends. If you're careful & use a nice, sharp exacto blade, you can remove the overmold & still re-use it later (as I've done). If not, I guess you could just use a nylon cable tie at the split point, or I guess you could even just go with nothing. After completing the above, my split point ended up looking like the pic below. I applied some glue to the inside of the overmold, re-inserted the wires, and finished it with some heat shrink tubing.


Since the hd 25 only has a securing point for the cable on its right-side earcup, you may want to figure out a securing method for the left-side cable. Again, I guess you could go with nothing or a nylon cable tie (or your own method, whatever that might be). I used some heat shrink tubing. The end result looks like this:


Option 2: Cable exits from the bottom
The obvious alternative to Option 1 is to simply flip the cups around 180 degrees so that the connectors point straight down. This is definitely a viable alternative, but as there is no strain relief with this configuration, there will be some stress on the connectors and the cables over time. In the end, I did end going with Option 2 (in spite of the risks) even though this is not shown in the pics. I think aesthetically, this option is a little better...the wiring ends up looking a little cleaner, imo. As a side note, if you do decide to flip the cups around with the connectors pointing down, it is possible to remove the hd-25 badge on the left earcup and flip it 180 degrees as well to match the new configuration. If I remember correctly, there are some plastic alignment nubs in there, but they can be safely clipped off & the badge will still stay firmly in place without them.

Next you need to decide if you want to keep the 1/4" jack from the stock 650 cable (and use some sort of adapter when you wanna go with 1/8"). I use my hd 25 most often in my mobile rig, so I definitely wanted 1/8" only. I also used this modification opportunity to cut some of the length out of the cable. It was too long for my mobile needs.
So...if you decide to go this route, you'll need to know a couple of things. The ground/signal conductors inside the hd 650 cables route in the same groove. They are stranded, and color coded. As I recall, there is a copper-colored grouping and a green grouping. Each and every strand inside each grouping is covered with a non-conductive, colored coating which allows them to route in this single groove without making contact between the signal grouping and the ground grouping. I had some concerns about soldering due to the non-conductive coating, but after some experimentation, I discovered that by applying a soldering iron & some solder directly to the coated wires, the non-conductive coating melts right off & allows the solder to do it's thing. So the non-conductive coating ends up being a non-issue really. Just twist the color-coded grouping together and solder as you normally would & watch the coating melt away. ***Very Important! Make sure you don't mix any of the copper-colored strands with any of the green strands or vice versa! Just one strand is all it takes to create a short between signal & ground.*** It's not apparent which color is ground & which color is signal...and I don't remember. Just use a multimeter & measure to be sure.

I found a nice little Neutrik right-angle plug at www.thlaudio.com ... this was what I used & the end result is pictured here:


Here's the finished product:


Peace,

Graz
i think i'll return the hd650 cable + get the 74532 cable and a neutrik right-angle plug

then for some soldering.
mh, i guess i'll find someone to help me with that...

Helo thee knowledged ones.

Well its time for me to buy another pair of headphones, currently Iam going around with a pair of Akg K81DJ, but damn they hurt my head after 30mins(or so) of use. Its the size, the headband (the middle part of it) pressurizes my head, it gets irritating after a while. The Sound is okay, nice bass and so forth.

Thats for background, to my question; How is the Senn HD25-1 in the comfortability area, are they bigger than K81DJ? More adjustable in size?

Hows the Sound; similar to K81DJ? Similar but better? Its so ahead u cant even compare?

atm I have a iriver Ifp-999 mp3player as source, but its gonna get replaced in the near future.
