I was handed down a pair of Sennheiser HD205 headphones. I had used them a few times before and they sound awesome! However, since I got them they make my music sound weird. For example, sometimes it turns every song into an instrumental version or it is really soft and will get really loud if you jiggle the cord right.
I cut off the jack and found 4 wires inside. 2 copper wires, 1 copper wire painted blue and another copper wire painted red. I removed the paint using acetone nail polish remover and fine sandpaper. Now that I have the exposed wires, I connected them in a new 3.5mm jack from radio shack. I think the colored wires are + and the unpainted copper wires are -. Note these wires are actually bunches of wires with tiny radiuses.
Sadly, when I connect the wires in I still have the distortion problems. It mostly has to do with losing the vocals. If I move the balance on my computer to all right or all left it will sound perfect. If I also connect the former red bundle to the ground of the 3.5mm and the former blue to either the L or R I can get mono.
I am thinking of cutting the wire higher and repeating the acetone procedure and rewiring again. Will that work because I don't want to keep cutting and cutting and eventually cut the whole wire to small pieces!
Your help is greatly needed and most appreciated. I really think these headphones will complement the voodoo sound on my I9000 nicely

Balancing audio?
I know this is probably a bit late. But i had a similar problem. My Sennheiser HD205 Headphones Started acting weird. They have an excellent sound of them and are really comfortable for someone like me who would wear them for a long period of time. Recently I had to get the cable fixed that went into the actual headphones because if they moved ever so slighty all sound was gone. I got them fixed and then the sound went weird the next day, when ever I played a song with a heavy bass, once the bass part came on the whole song was muted until it stopped and the vocals were distorted, then I was playing around with the sound settings on my computer and i noticed the audio balance was a bit off then usual (Left=78 and Right=78) so I brought them back down to 50:50 and it was all better . I thought maybe you should try that, seeing as nobody else left a suggestion! (If you dont know where to find the sound setting on your comp, go to: Control Panel>Hardware and Sound>Sound, and a window should pop up. right click on the speaker output you use (its called Speaker by default) and click properties then click on the tab properties and balance it to 50% on both sides) NOTE: Make shure your not playing any music (eg. Itunes) while your doing this. it MAY stop the program from working! Good Luck!

Hello,
I had the same problem. Unlike most headphones, the Sennheiser HD205 uses two separate ground wires, these are the two uncolored wires. The red one is for the right (the pin that's closer to the middle) the blue one is for the left (the pin that's further from the middle). The colorless wires both go to the ground pin.
I connected them this way, now I don't have any distortion, and I can hear the vocals loud and clear on both sides.
Sounds like you don't have ground connected to the signal source (jack).
If the jack has 3 connectors (tip + 2 sleeves) the wires go like this: tip - blue, first sleeve - red, second sleeve (furthest from the tip) - ground (usually golden).
Try an connect the two sides separately and check if they work individually. Only then connect them both. If the cable doesn't have any shor circuits it should work just fine.
Good luck!

This is not something new and have been shown many times in YouTube. It is interesting to have for any phone with 3.5mm audio jack that can be easily done within a few minutes. I do not use my headset with my phone so this would be a nice hack to have around to listen with your friends on some local radio without consuming your data plan and phone battery.
Find a headset that you do not need. We only want the part with the 3.5mm audio jack. Just trim it down to about 20cm in length and fold it in half and tie a knot at the end. I tied a lasso knot at the end just so I can adjust the length of the receiver later on though it may not help much in reception quality.
Tested several length from 1 meter all the way to 20 centimetres and found not much difference in reception quality for a fact that you will be using your loudspeaker to listen to the FM radio. The same with whether to loop or not to loop the receiver but looping the receiver gives it a cleaner look while maintaining the same reception frequency.
Putting your phone too close to a human body greatly interferes with the FM signal. On the other hand, placing your phone on a metal table may enhance the FM reception.
Perhaps those who have knowledge in electronics can shed some light to optimize this simple hack further.
Have fun...
I didn't know. Works like a charm !! Thank You
Doesn't work for me. When I plug in the trimmed headset cable with the ear pieces cut off, the FM App keeps asking me to plug in a headset. Works OK when I plug in an untrimmed headset and switch to speaker in FM App menu.
Is there a further trick to getting this to work? Are you using the stock FM App?
I had the same problem myself, and it stems from the fact that smartphones will interrogate any headset you plug in to check if it is suitable. There are basic stereo headphones with three contacts on the jack plug (from the tip they are left, right and ground) and should work on any phone regardless. But there are two variants of headset (i.e. those with a microphone) that use four contacts, the difference being whether they connect the mic on the third or fourth contact.
As of 2016 most manufacturers have standardised on one system (left, right, mic then ground), but there are enough older phones and matching headsets out there that use the alternative pinout scheme. For example my old Sony Xperia used L-R-G-M (the same as say Blackberry), necessitating the use of an adapter for certain accessories. My latest Z5 however, has moved to the L-R-M-G pattern, which means I can no longer use my favourite old Sony headset anymore, not even as plain headphones, the Z5 just refused to talk to them.
That explains why a dumb wire might not work with a smartphone, because it is looking for a signal loop on all four (or three) contacts to try and figure out what's been plugged into it. The solution is to short out the wires to fool the phone into thinking there actually is something on the other end. Simply bare all of the wires at the cut end of the cable, burn off the fine lacquer or cotton that is used as an insulation, then twist the wires together to short them all to the ground. Better still, solder them together and cover with a bit of heat-shrink for a proper finish.
Found some pre-made antennas in ebay, you can try searching for 3.5mm antenna. They look pretty decent. I am also looking for compatible antenna, if any, that is compatible for steven303's new headphone jack.
Edit: did some research and found that the 3.5mm steven303 mentioned is called '3.5mm 4 conductor' or 'TRRS antenna 3.5mm', you can try searching for them in ebay or look for similar ones lying around with wires long enough to be loops around to be used as antenna for new phones with the new type of head jack.
I got two item I think can be suitable for this purpose; search with the following keyword in ebay;
1. 3.5mm 1/8'' Male To Male 4-Pole 3 Ring TRRS AV Audio Extension Cable 1.2M/4Feet
2. 4-Pole 3Ring TRRS 3.5mm (1/8'') Male To Female AV Extension Cable 3FT/1M Black
I have an additional issue. I use my phone's fm radio feature with an old pair of headphones for an antenna and listen via blue tooth headphones when I'm running or just working around the house, etc. My problem is that as the phone moves around in my pocket, the movement causes the phone to think the headphones came unplugged for a second and the radio turns off. When that happens I have to take the phone out and turn the radio back on. This happens often enough that it is a pain in the neck.
A separate but related issue. With some old, non functioning headphone cables the phone doesn't think there is anything plugged into it. I am lucky in that my phone gives me the option to "Play anyway through speaker or bluetooth". So even though it thinks there isn't anything plugged into it, I do, and I have good FM reception.
Here is what I want: I want to know what to do to my old headphone wire so that my phone doesn't think there is anything plugged into it when it is, in fact, plugged in. I hope that makes sense!
I searched around for some better headphones for my galaxy S3 (GT-I9300), to unleash the full music experience the phone got. As I prefer a more powerful earphone I feel not as comfortable with the sound of the original ones, but I don’t wanted to lose the comfort of the Samsung Headset - Microphone and Remote control.
As you can see here, I changed the original Samsung headset cable to a pair of Sennheiser Headphones. In case you are interested in doing the same here is what I Did.
What i used:
A Pair of Samsung Headset Headphones, in my Case Samsung Galaxy S3 (GT-I9300)
A Pair of Headphones, as shown in the Pictures a Sennheiser CX 300-II
A Solder Station, a bit of soldering wire
A Tool called third Hand, or another little vice
Fine Pliers and a little slot screw driver
A Voltmeter
Just to ensure. I am not responsible for any injuries, damages and defects on the headphones, your mobile, other components or your health. The following hints worked for me and my equipment, yours may be different.
If you aren’t use in Voltmeter testing’s, soldering and fine mechanical works you shouldn’t do this.
First I dismounted the silicone Ear Adapters from all headphones. Then I used the pliers to demount the Samsung headphones. In My case I grabbed the stick where the Ear Adapter was on and ripped it off. I have no further use for them, so I broke its housing.
Inside the Cables are mounted on the speaker. I used the solder station, to liquefy the soldered cable connection from the speaker.
In next step I opened the cable knot and got the cable out of the Samsung housing.
Openig the Sennheiser Headphones:
I used my fingernails to get of the silver ring of the housing, maybe also a guitar plektron will do the same. In my case it worked when I turned it around while pressing my nails in.
Please see Picture 1
With the little slot screw driver I opened up the in key and slot position of the housing.
Please see Picture 2 and 3
I also used the solder station, to liquefy the soldered cable connection from the speaker.
I noted myself on which connection which colour of wire was. On the back side of the Sennheiser Speaker there was a red sign on one of the contacts.
I opened the knot and pulled out the cable. Then I inserted the white Samsung cable in the rubber bumper. I think its important to make sure inserting the right side of the Samsung cable into the right side of the new Earphone. To ensure better gliding I used a little of my wives hand cream on the cable.
When mounted the cable in the headphone, I fastened it again with a knot. I had to be carful, the cable isn’t as strong as it seems.
This is the pin configuration I measured on my headphones. As I heard that there is more than one pin configurations in different countries, please ensure what’s yours. So the wire connection I made may differ to the one which is the correct in your case.
Please see Picture 4
Soldering, I made,
Please see Picture 5
Right Headphone:
In my case I attached the red wire of the Samsung headset cable on the Sennheiser headphone at the solder position where the red dot was.
Left Headphone:
I attached the green wire of the Samsung headset cable on the Sennheiser headphone at the solder position where the red dot was.
Please see Picture 6
Reassembling should be no problem then.
Have fun with your modified headphones.
Please see Picture 7
Nice work looks pretty good do they sound alot better?

I think the originals are ok but, I'm am a bit of ambitious in music, the original samsungs speaker don't have such powerful bass and not so clear highs. So they don't give a good picture of what a great sound experience the Phone itselve provides.
If you buy a original Headset at Amazon its about 5€, the Senheiser are 35€. There might be the difference from .
Greetings
Awesome
I don't understand though why you used the samsung cord couldn't you have just bought headphones from amazon that had their own cord? Or did you have to have the samsung cord because of the plug to match the microphone? Thanks

Nice job. Thanks for sharing.
Hi,
I have been trying to troubleshoot my issues and have had no luck.
one day my headphones stopped playing in my right ear so I figured it was a bad headphone jack. I bought a new one and replaced it. Now it only plays when button control headphones are plugged in (the plugs with the 3 black stripes not the 2 like standard earbuds). It does play but if I turn the headphone plug it stops playing at certain points while turning. the rear speaker works fine.
I tried having the jack plugged in with the metal outer case off and I have the same issue (again, I don't think a short is an issue).
I checked everything and the headphone jack appears to be fine, doesn't appear to be a short anywhere. I am at a loss on what my next step would be.
Thank you.
There are lots of possible solutions, that you can try.
Sounds like you might just need to replace the audio receiver.

I've had Samsung's in the past but decided to take a chance to buy the above phone due to cost saving.
The supplied earphones work perfectly though they are bigger than the bud type supplied with galaxy phones so they hurt my ears after a short period.
I've tried plugging in my old and a new set of Samsung headphones but they at first make a deep buzzing sound with low sound coming through, after moving jack around and pulling out a bit the sound works but as soon as I let go the sound goes back to buzzing again.
After inspecting the jack plugs I noticed that they are quite different, one is bigger than the other and the rubber rings are in differing points - until now I never new that jack sizes were different. I've attached a picture of them together (gold are Samsung)
my question is can I get a pair of bud type headphones with the larger plug? if so what do I look for?
I thought I'd ask hear before considering Bluetooth headsets.
thanks in advance.
same problem
I got the exact same problem and also discovered that if you remove the case, the smaller headphone jack will fit. Although this is not a solution. Sometimes i just loosen up the case a little on the area of the headphone jack so that it does fit. I'm looking foor a bigger jack now too.

Is it normal that the headphone jack is a bit wiggly, can wiggle a little bit up, down, left, right... Headphones still click a bit harder than on another phones, and are harder to remove, but when inside it seems to wiggle a little bit... Sound is working normally (although audio seems a bit on the left side (very, very slightly, I don't know is it my imagination or what, I don't know is it actually more on the left, but right side adds some weirdness to the sound and my ears feel clogged after listening), but I have a cold so I don't know is it me or electronics) , I am just worried is this a normal thing...
Mine is same but sound is normal. So i don't care about it.
I think its the male connector. I have TRN V80 IEM and it wiggles so i went to showroom and I connected the IEM to demo G7 unit and it still wiggled. But all of my other earphones are fit. So i think its the male connector.
