Shure Olive Guide (Strech & Decore)(Photos)

post #1 of 3
Thread Starter 
Disclaimer: Both of these ideas came from this forum.

Equipment:

Headphones: In my case I own Panasonic RP-HJE900

Shure Olives $13

Needle Nose Pliers (I paid $15 for a kit at Lowes)

X-Acto Knife $4 (Fresh Blade!)

Optional (but a useful tool)
Flush Cutter $14 (not to be confused with Side cutters/Diagonal cutters/Snips ect )


First I went with the Stretching method.




-Just put the pliers until the tips hit the end of the plastic tube so you don't strech the ends more then needed.


Put something in the back of the pliers so they stay streched, leave for a few minutes, then rotate 90* ~ repeat.
(Notice I use a paint brush in my pliers.. yeah, the paint brush method discussed on this forum just caused me to mutilate my tips from putting them on and off different size brushes)

Finally once stretched enough keep the pliers in and streched and get the lip of the headphones into the olive and then slip the pliers out. Yes, this will be a pain and takes a few tries.

This might be the end for you...
However I found that in my setup this destroyed the bass response. I attribute this to the long distance between the driver and the tip of the olive and the super narrow tube that the music travels down. (This might increase the sound stage ect ect ect)


De-Coring


Keep your X-acto angled so that you cut close to the center tube as much as possible. At first I recommend you use a stabbing motion cutting to the tip of the olive, then pull out and move a bit forward. Once you finish the first circle I suggest that you keep it in the groove and use a slight sawing motion. Go in a couple rotations so that you get a clean cut (the area at the tip will be the hardest)



I'm sure many of you can do even better on your core getting almost no foam when you pull it out. Notice the much bigger hole in the olive.. we can fix that.






The olive is already to long for my IEM, so I will kill 2 birds with 1 stone. If you cut the Olive you will not only get the driver closer to the tip of the olive (which is close to stock) but also the Olive is tighter towards the tip.






(*Note, I used my Flush cutters instead of the X-Acto knife on the rest of these and they came out better)

It's hard to see, but the driver is only a bit under the tip of the Olive, which is closer to the stock headphones. This increases bass response to a normal level in my case. Also, because I cut 1/4~1/3 of the big end of the Olive off it was much tighter.

FYI The Olives stay on my IEM without any further modification. They stay on unless you pull on them pretty hard (I haven't had them come off in my ear yet, but maybe after a few days/weeks/months that will change who knows)

The Olives in my opinion modified (decore) feel better then stock, stay in better, Isolate better, and sound about the same to me.
(Tip: I wet the Olives ever so slightly when I put them on so they get a better fit.)

Hope this helps.

What if the olive isn't too long for my IEM? How would I go about getting a tight fit on the nozzle?

Others have used a method of gluing a piece of plastic or heatshrink where the tube used to be. Before you starting modding your Olives I suggest you have extras in case you ruin one
