this is what i got, now how do I open them without prying all the plastic enclousure?

Doesn't the rear cavity volume/air leak determine the bass response? I'd be careful about opening up the back.

Ok this is where it gets slightly tricky. As your cables are already disconnected I am going to assume that salvage is not an issue cablewise.

 

Take an Xacto knife with a number 11 blade. Carefully go around the rear edge and cut out that circle (the one with the hole in it) It's thin plastic so it doesn't take a lot of pressure or time. With that circle removed the cable end plug will be exposed. Take a hat pin or pick and prise out the cable plug and rear of the driver is there.

 

There is no real worry about bass venting as that hole was covered by the logo disc in back and sealed by the cable end plug in front. The only real "porting" is in the top of the housing where metal meets plastic and through the cable strain relief jacket itself.

 

As an aside I run these with the rear fully open and they sound quite good.

Anyone that has the VSonic black stock tip should give the a try with these MH1Cs. :)

 

Man oh man re-listening good ol' Sony MH1Cs again with the black stock VSonic tips is CRAZY nice!!! The sound is actually more clear with better dynamics due to the stiffer VSonic tips/ slightly wider bore compared to the gel-like stock tips, which made the sound more bassy/ smooth. These are still sonic diamonds despite all that has transpired so far, still likes them better than the LG Quadbeat 2s, though technically they are almost on par and is wayyy better than the Pistons.

 

These even puts the FAD Vs into proper perspective tbh, cuz they have VERY similar sonic characteristics/ presentation. The FAD Vs no doubt sound more refined and is technically more superior in every way but it ain't even THAT far ahead. My lame sauce sources back in the dayz didn't do these MH1cs that much justice, these sound so sweet now with my simple venturecraft go-dap amp hooked into my ipod classic. :basshead:

 

The schitty cable is still the same ol' schitty cable though. haha Nuff said.:triportsad:

On Mine the logo cap was just on with what appeared to be contact cement. A small jewellers flathead screwdriver popped it off quite easily.

The trick then is the cabke plug end use a pin or something similar to pop out the cable plug and genltly pull it through the"strain relief" jacket. It moves pretty freely once you do get a grip on it.

 

This is not a mod friendly earphone and 3rd hand vise is pretty much mandatory. And a really good hig mag loupe.

 

Edit. Now this is Odd. I just popped open the other driver and under the logo cap is a plastic cap with a hole in it. This appears to be molded into the shell. I cut that away with an xacto knife (it's about 1/5 mm thick) and the cable end plug is under that. This was not present on the other driver, which explains the awful channel imbalance these have. Hmmm.

 

I wouldn't think this would affect channel imbalance as long as they are both properly sealed other than the vents. But perhaps you are correct. I'm looking for a cheap mh1 to destroy, so I'll let you know if mine is the same. Did you open both sides cls? Is one of your sides open? I'm assuming they must all be the same like that. Strange.

I'm assuming a manufacturing flaw. That the one side had the end sealed and the other was open. The cable end plug is not completely circular so I think the slight volume difference in the chambers was the culprit. With both ends open the balance is fine.

makes sense.

In retrospect if I was going about disassembling a pair again, I would most likely try heating the steel sleeve a little to see if the rear capsule would pull out. I am not about to go into any more RD on these though:D

post #2994 of 3333

So I'm having the same issue as a lot of people with the sound being super low and muffled on one side.

I did see some moisture on the membrane so I tried to let them dry out lose moisture but the sound just aint coming back.

I've had them drying in a well ventilated place for a day now and still nothing.

It's so bad, that the left side is nearly completely inaudible compared to the right.

Is there anything else I can do? Should i try and open them up? If so how would i go about doing that without destroying them :S

bought a X cacto style blade today since I only have those big clumsy box cutter knifes at home

you will need

drying agent for these small home/office type single use dehumidifiers http://www.ebay.de/itm/161251897463

a lock&lock box http://www.ebay.de/itm/251179150630

 

just put the phone in the box close it and leave it for 24hours should work fine, I "repaired" alot of smartphones, Handheld gaming devices (gameboy and stuff) with this easy technique

 

kind regards

Serhat

An alternative to the drying agent is a simple bag of rice. The rice will leach moisture out of just about anything.

Rice will attract Asian people and these will repair it overnight.. Just kidding but rice will work to. I successfully dried even smartphones and stuff that have been completely submerged into water classic water closet accident

I saved a friend's entire laptop this way. He spilled water all over it and it was working. I had him put it in a box full of rice and a day and a half later it was fine. He still uses the laptop today.
