Default Koss KSC75 behind the head conversion

So I have had some ksc75s in my drawer for....well, ever. I dont use them because they are a pain to get on and they dont press on my ears enough for me to get the good sound from them. I have been thinking how great they would be if I could get some press to them. The parts express head band mod is kind weak in that area too. I have seen a set mounted to a px100 band, but they are pricey phone to rip apart. So I decided to practice on a set of cobys I had laying around from a portable DVD player.

First I popped off the drivers. that was easy. just pull. Finding out how to remove the plastic backing was tougher.



After poking around it for a little bit the silver logo piece went flying and exposed a screw.



took out the screws and pulled the wire out of the band. and ended up with this...



I used a nail file to grind down the little nipple on the ksc75 to get a flat surface. Here is where I did something dumb. I was doing all of this at work and didn't have my small drill bits. So I thought I could just use the screw to thread the whole. Of course this ended up being crooked and jacking up the montuing surface. I hate being impatient sometimes. It causes problems. So after I messed up one of them I decided to wait. When I got home I drill out the other side and was able to get it on the headband.



I am going to try and build the mounting post back up with epoxy and then drill into the epoxy and see if it will hold a screw. If not...hot glue gun, here I come.

finished...but unfortunately this became a permanent mod instead of the reversible mod I originally intended. the side that I threaded crooked had to be reinforced with glue once I got it on there. behind the head experts may notice that the drivers are a bit forward on the arms. no choice because the mount point on the Koss were mid driver instead of on the edge like the original drivers. its ok, it still fits on my head and feels like it clamps ok. I have to let the glue dry for a couple of hours before I put it anywhere near my ears. I like the Koss but dont really want them glued to my head. I'll stop typing and post pics since that the only thing people care about anyway...

just slapped them on for a second and noticed right away that I can hear that bass response that I know these can do. cord is already annoying me so recable to make them single side entry will be next.

That's one thing about the KSC75 when used as the default clip-on...no bass response, they sound wimpier than my Grados unless I press them against my head with my hands.

thanks...I thought I just had a weird head. Seriously, I was getting a complex because of the way everybody raves about them.

I've never bothered getting a headband for them, since they only cost me $5.74 apiece for the two sets I got....I just add a bass boost to them. One of them is dying now, the cable connection into the volume controller is getting sketchy, and sending them in to do a warranty replacement would cost as much or more than I paid for them, so I don't know if I will do it or not.

where did you get them for $5.74? If I ever get my hands on a px100 headband I still want a foldable set of Koss...that dont look like the portapro.

Couple years back, they were on clearance at Radio Shack....when I bought them, I was upgrading from Skullcandy Ink'd (first thing I ever got besides stock Fuze buds), so I liked the KSC75 so much I went back the next day and bought a second one, and I gave the Skullcandies away the next day.

was super easy. try to find one that mounts a bit more centered if yo can. some may not like the tight fit on the top of the ears. I only plan on using these about 3 hours a week though, so its cool

If you prefer a headband to a neckband, it's even easier: http://anythingbutipod.com/forum/sho...75&postcount=7

eh...that one has very low clamping power from what I hear. Didnt think it would do what I wanted. It is a popular and super simple mod though.

That headband works fine for me, it stays in place well.
