Can I fix the my headphones so the sound in the left ear works?

My BOSE headphones are about 3 years old. Sometimes the sound in the left ear stops working. If I mess with the connector cord, where it connects to the computer, then I can get the sound to work.

"it looks that the cable is broken near the connector - if is cuts in and out when you move the cable near the connector, not the plug itself.

If you intend to replace the cable anyway, I would cut the cable say 10cm from the plug, to get access to the inner cables. there should be 3 or 4 signal paths: Shield (optional) equal to ground, ground (usually black), right channel (usually red) and left channel (Mostly white).

you then can strip the wires back, connect the ground by twisting the wires together, and try the headphones by touching the others together.

In your case you say get right all the time, so use the red from the plug with the left channel from the headphones and see it it works reliably, then use the right channel from the plug with the right channel from the headphones just to confirm that works too.

If it checks out, your headphones are proven ok, and you can either replace the cable, or just solder on a new plug, as the break seems to be near the old plug in the cut off portion (this is the case most often)"

"You may only have to replace the mini stereo plug you can get that at Radio Shack or a local electronics/hardware store.

Do Not use too much heat! you can cause short circuits if you melt shielding.


Red == Right == Ring.

Good Luck,

I would send them back to Bose. The are a good company and in my experience dealing with their headphones if there is a problem I send it to them and it comes back repaired. No charge. Be sure to obtain a return authorization number first.

"Often times dirt will contaminate the contacts on the female part of a 3.5mm audio connection, and these Bose headphones aren't immune to this problem. The symptom of this is audio that cuts in and out when you rotate or apply sideways pressure to connector on the end of the cable.

To fix the problem yourself, moisten one end of a cotton swab stick in rubbing alcohol (do not soak it). With the headphones held upright (so that drips exit the 3.5mm jack instead of entering the speaker assembly), gently clean the metal contacts. Also clean the connectors on the cable. Allow 15 minutes for the rubbing alcohol to evaporate before using.

Do the same for the audio source (an MP3 player, stereo system, phone, etc)."

"does it work well plugged into something else? other than the computer?

also bose should offer a repair service to their customers for little to no cost... probably try that route first before replacing the cable and voiding any kind of warranty they might offer"

"This is a common weakness in BOSE headsets. You need to replace the jack to do the job right. It is a simple $1.00 part at Radio Shack. If you don't know how to do it there is an excellent video on YouTube which walks you through it.


Also, Rich's Methods (His video's are ALL awesome) has a no solder method which is good for the more non techno among-us!


Good luck. It really is an easy fix and your BOSE will be working great again. I buy a lot of these sets on eBay and repair them to resell. I can buy a pair for $10 & resell for $75 or more depending on the headset. Some people don't want to be bothered fixing them and will sell them for parts or repair for next to nothing not realizing they could do the repair themselves for next to nothing.

God Bless,
