How to take apart

My left headphone rarely works, the only time it might work is if the is tilted head set in a certain position, usually if i just tilt my head to the left the headphone will work to a certain extent. I do not know why this started happening. I took good care of the headphones, but one day this problem seemed to just randomly start. Could you tell me how to take apart the headset to try to repair the wires in side with out making the problem worse I have only had them 2 month and already a short in head set I am a women and have never tried this before but so tried of buying pair after pair thank you so much any info i would be grateful for

I figured out how to remove the headphone clip without causing cosmetic damage to the headphone casing. Unfortunately for me, this was after I had scratched up the casing already. Anyway, to avoid the cosmetic damage, use some kind of plastic tool, like a plastic spoon. After pulling off the headphone cushion, you will see the aforementioned 4 slots. Carefully slip the handle end of the spoon underneath one of the slots(not through them), and apply gentle pressure toward the center of the speaker. Do this for each of the 4 slots, and the tabs should easily come loose. Hope that helps.As for figuring out how to get the headphone to work, I'm waiting for that solution myself. The right headphone is out, but the left one works, none of the wires are loose, so the damage must be from my nephew being careless with the headset cable, and probably tugging on it once too often. Don't let your 15 year olds use your headsets, if they tend to be clumsy :)

On the side that has the wires going into it remove the Padded ear cushion. There is a Black Ring with 4 holes in it this is basically a clip you do have to pry a bit at it but it does come off and with some luck without snapping, luckily mine didnt. There are then 4 small screws exposed to dismantle. And thats it now all wires are exposed hope this helps.

I was facing this same issues around a week ago. Left speaker became inoperable, only periodicly playing sound. Just by that symptom I knew there was a short or a disconnect somewhere within the wires. I was just hoping that it wasn't somewhere in the plastic that the wires run. Here are the steps I to correct this flaw in my Logitech headset. (This will not work on the Logitech USB headset.) I removed the black padding that goes around the ear. This is pretty easy just needs a little bit of force. Dont be afraid to remove it. It is just a force clip, meaning it is just pressed between 2 pieces of plastic not fastened to any specific part. After the black padding is removed you will see a black ring with 4 screws. Remove the screws and pry the plastic ring off the silver headset. (I used an apple iPhone repair tool, but a simple guitar pick or thin credit card should be just fine.) After the black ring is removed you will have a series of wires paired by small solder sections in my case 2 soldered and 2 shrink wrapped. The problem lies within the 2 shrink wrapped pairs. They should be ("red and blue/green") I can tell these headphones were assembled in china or some other mass producing country because there is no care done with the shrink wrapping. Simply grab the black shrink wrap (black rubber sleeve) and pull it off. It should slide off rather easy. Once the shrink wrap has been removed from both pairs, check to make sure they are connected properly. (Note: These wires are extremely small and can not be stripped, they are dipped wires so if you need to remove some of the coating, take a common house lighter or match and wave it quickly over the wire. (PLEASE DON'T LET CHILDREN DO THIS. KEEP KIDS AND UNSUITABLE PEOPLE AWAY FROM LIGHTERS AND MATCHES ;) ) This method will crackle and pop the wire until the coating is gone. Twist the pair together. After both pairs are properly connected push the corresponding pairs (try each) onto the silver soder on the main speaker. (Listen to both speakers to test.) You should hear both speakers play loud and clear! Now you can tape the correct pair back to the soldered section of the headset (a small section maybe 3/16th of an inch was enough for me. May vary with each case.) Now your wires are correctly positioned. (BTW do not glue the wires to the soldered section as glue does not conduct electricity. Use electrical tape.) After everything is in place reassemble the headset plug in and BOOM! Better sound than the first day you bought them! I hope this helps someone! Have a great day and new year!

FIXED****
I had the same thing happen today, and I fixed it by taking it apart by the some of the tips on this page. After i got it open and apart, i plugged it in and starting testing to where the connection was being broken. It was right at the section where the headset and cord meet (there was actually a crease).
So I cut out a one inch section of that creased part of the cord. stripped the 2 ends (headset part/cord). I then matched up the wires (thin red, thin copper, thin blue, thick copper, thick white). After twisting the matching wires, i put a pin head of sodder on each connection and then wrapped a small piece of electrical tape over each one. (i tested it right here) I cut off the excess tape, fit all the new connections behind the speaker, screwed everything back together, put the pad over the black ring and viola! It works like new!
I love these headphones, this bummed me out, that it stopped working. But it totally made my day that I got them working again! Thanks for everyone input and I hope this help someone else!

SOURCE: Left headphone does not work properly

Hi,

Based on your post/description, it would seem that the cable of your head phone developed an open circuit somewhere. I would assume it is pretty near the headset itself. On most occasion, it is at the very entry point where the cable goes into the headset.

Normal repair would involve opening the side casing where the cable enters the headset, cutting the cable about 3 inches from entry point, strip exposing the three or 4 wires and reconnecting inside the stripped ends. Effectively what you have done is trim the cable a bit shorter eliminating hopefully the intermittent section.

Hope this be of help/idea, Post back how things turned out or should you need additional information.

Good l;uck and kind regards.

I got new Logitech Clearchat stereo headphones. I plugged the two pins into the pc - pink and green. When I do a skype test I hear the message from my computer speakers (settings says Realtek HD..with no...


realtech hd is your sound device. go into windows control panel and access the sound settings then navigate to voice settings click the volume button,your mic might be muted. also if you want the headphones to work plug them into the plug that your speakers are using (side-note: mics and head phones never need something installed to work as long as your sound device works and your definitely does work,only when the mic is a special interface like USB do you need to install software and/or drivers)

I am only getting sound in the left earphone of my Samsung SBH500 headphones. I just got them and the right earphone did not work upon receipt, should I return them or am I missing something?


There must be some fault with the pin you inserting. adjust the pin and see whether u get signal in both sides.
orelse chnage the audio settings of the audio u play.. like if it is in stereo change it into mono,left or right.
if it is not working change the headphone. it is a faulty one.

My microphone will not work, and my computer won't recognize!


Common problem with this headset.

In short, the wiring for the mic in the left earpiece is quite shoddy, and over time will be worn away by changing the mic position or come loose with minimal effort.

Have had a over a dozen of these fail in our internet cafe due to this issue after a couple of months use.

Labtec headphone how to get it to work.


Sometimes you need to "burn in" your headphones. Used headphones usually produce a better sound than new ones. Simply let it play some music continuously. I usually burn in my headphones with some AM/FM static.
After a while, the sound should improve.
Good luck!

Can't hear sound on one of the headphone's speaker


It's less common for one of the speakers to go bad in a set of headphones. It's possible - but there are more common problems that will cause this. I assume you have tried the headphones on another device to rule our a problem with the device you are currently listening with and using the other device, you still only hear audio from the left speaker.

The wires in the cord that connect the plug to the headphones are very thin and are susceptible to breaking. The most commmon place for these wires to break is at the point where the cord is flexed or stressed the most. Those points are:

1. Right at the plug
2. Where the wire enters into the left and right speaker.

There are occasions where I have seen the wires become unsoldered from the speaker terminals within the headphones themself.

What You Can Do:

1. While listening with the headphones, try flexing the cord back & forth at the plug and where the wire goes into the right speaker. See if the audio will come back and cut out again.

2. What I have done is cut the cord about 3" back from the plug. Go to Radio Shack and purchase a new plug and install a new plug on the cord.

3. You can also take the headphones apart and cut a few inches off the cord where it connects to the right speaker and reconnect the new end of the wire to the right speaker. The goal is to cut away the bad part of the cord and re-attach the good part back.

4. You can try to replace the entire cord but I haven't been able to find replacement (THIN) cords too easily.

Good Luck,

- Jim

Pairing s9 headphones w/krzr


OK I managed to get my head set to work. Make sure the unit is charged, press and hold both the 'ON' button (on neck piece) and the "PLAY/PAUSE' button on the right earpiece. Keep holding then the LED should flash Blue three times THEN flash alternate RED and BLUE. You should then be able to Pair the Device. Good luck
