There is a very easy way of puting the pads on with no soap and no trouble at all.

I will do a photographed guide later today or tommorow.

Kewl. I had no trouble, but others have had problems.

There it is, the Veloure Pads guide:

1 - Pull the elastic parts on top of the veloure:


2 - The pads will look like this:


3 - Pull a small part of the elastic side back to its original position like this:


4 - Place the pad on top of the cup so that the elastic part you pulled back will be on top like this:


5 - Just hold the pad in place with one hand, and pull the sorround elastic back to its original position.

That is it. No reasone for prestreching the pads, no need of any tools, no need of any type of soap or other chemical that will eventually dry the elastic side of the pads.

I think this may have something to do with the two 'versions' of the K340. Both of my pairs have been the bass light version, and removing the cotton and taping up the backs balances them out nicely. Aerius' pair it the bassy version and he ended up using blue tak, some cotton and no tape on the backs. He was getting some werid resonances when the cups were empty. Mine don't seem to have this problem, and the extra bass from the taped backs is a welcome addition with my pair. I do think that there are other benifits from the taped backs as well in the area of soundstaging and imaging though...

Mine are the bass light version. I had the bass heavy and sold them, they weren't as good.

It might change a bit with amp and source I guess because in my case the taped back affected the bass and had almost no affect on the rest of the sound. When I took the cotton out it sounded "brighter" but actually the extra "detail" is just resonanse from the plastic which looses clarity in the sound.

Omer (MrShadow) nice to see you are following this thread too

Well, I am very sensitive to resonances... one of the reasons I hate the Sony Qualia... but perhaps I should try tweaking mine with varying amounts of cotton at some point.

I really think you should. Not only because I think there is resonanse (which is the one thing that I hate the most! that is why I barely listen to my speakers which are affected by the room). I also think that playing around with the headphones is a great hobby, and a great way to get the sound just right for your seup, music, and ears. That is why I think DIY is the best (besides the fun and low money expance )

markmaxx, I've had the pleasure of listening to your headphones at the last Dallas meet. Larry has performed all the mods on them. I can't remember if that pair has the fabric screens or the old version dremeled plastic screens Larry used to do. I wasn't aware Jeff had sold them, I hope he finds time to stay in the hobby. He's a great guy! In any case those are fantastic sounding K340's, and I wouldn't mess with success!
Thanks I love them. Jeff is out of headphones . He sold everything.

Jeff and I have met 3 or 4 times he bought my Meridian and I borrowed his K340s and then I paid for my K340. things like that. Jeff is a great guy.
Sorry about the hijack.
Jeff still has all the speaker stuff with the 14,000 records! I asked to be invited to listen to a good vinyl setup, he said he has yet to set it up here in Northern Va. I am going to have dinner with him sometime soon! Maybe I can get him to set the speaker stuff up!

Phildox,
I originally tried closing the back before bypassing the XO and rewiring the inside. Now I tried again (but in a diffrent way than yours - I used asmall piece of foam, covered it with black electrical tap, and placed it from the outside. The black tape keeps it in place and makes sure it's not seen as it's black as the cup, and when I put the headphones on the foam closes the back with the pressure ) I must say that it's sound better now than before the XO bypass. The extra punch in the bass is nice. I do think there is a small influence at the highs too, but I'll check it better tommorow morning.

First, open this screw and remove the plastics behind it:
Is that screw supposed to be insanely tight? I've been trying to remove mine for the past 15 minutes and it's not even moving.

No, it should come right out quite easily. Make sure you've got the right bit size to avoid stripping it.

I cannot believe I missed this thread for so long! Can't wait to mod my own pair! You've gotten a good start on it for sure, I'll be adding some blue-tak, headband replacement, elastics replacement, recable/CB bypass, screen replacement and some very nice wodden accents from swt61. As I have the bassier version I'll probably be playing around a little bit with some tak/cotton in the cups to see how I like it.

I have the right size bit size. It seems all the screws are ridiculously tight except the outside screw that holds the K340 cup faceplate on the left cup. All the other screws are impossible to get off.

Hey Azure,
That shouldn't be that way. Try "playing arnd" with the plastic plated a bit, and place a bit of WD40 lubricate and try again after a few minutes.

Redleader,
I want to get the wooden parts for the outside as well, where can I get them for a resonable amount of money?

BTW, I have decided that open cups are the right way to go if you want a bit more "magical" and refined sound.

BTW2, I have order the cable a few days ago, and I have order the TRS connector yesterday, now it's only waiting for them to arrive. Once they do, I'll place a bit of blu tak in the back, some anti-static foan on top of it, and listen to it for a few days to see how it works for me, and keep you guys informed.

BTW3, if someone is going to oder the headband, please let me know and order 2 of them (one for me) and send it to Israel for me (obviously I'll pay for it). I didn't think about replacing the headband when I ordered mine, but shipping to Israel was 30$ from AKG, while the headband is a small thing that can fit an envelop and can be sent for 2$ or so if someone here can help me.
