Question about Sony MDR-NC11 Consumer Headphones

Sony MDR-NC11 Left Earbud has no sound

About 3 months after purchasing these headphones, the left earbud started cutting out. If I jiggled the earbud while listening to music, the sound would come in and out. It actually seems that if I pressed the earbud into my ear, the sound would come in. When I released the pressure, the sound disappeared. The condition continued to worsen until now the left earbud does not work at all anymore. I'm sooo disappointed because otherwise I really like these headphones! Everything points to a problem in the earbud - not in the cable. I've looked for a service manual for free online, but can only find it for approx. $15. I *think* I need to disassemble the earbud to find the problem and fix it, but can't figure out how to get the dang thing apart and really need some expert advice. I have some experience with soldering (if necessary) and feel comfortable doing minor repairs. If I damage the headphone beyond repair, I'm okay with that because at the moment they're essentially not usable anyway. Thank you in advance! Brian I have the same exact problem. After about only 1.5 months the left earbud stopped working. I am so sad, I do not know what to do. -nat

They should come apart right where the metal meets the plastic, just below the buds themselves - be careful, one set like that I took apart were actually surface-mounted to the housing, there weren't any leads to repair...

Why did my left earbud become silent?

you can make both of the earbuds work. You can open the earbud where the speaker is that you use to hear the musik. Use a soldering iron and a lead. check if the wire inside has removed, fix it back and you will hear sound on both earbuds.

Take care.

Left earbud problems

Well, I had the same problem with the right earbud. Luckily I was under warranty with Target, so they told me to contact Bose. I did and they had me send in the headphones (to make sure I waas telling the truth) and about 2 weeks later I got my earbuds back. Their customer service is excellent, so that's what I would reccomend

Try another pair of headphonesif they work on both channels then your headphonesare faulty ..replace under guarantee if you have one otherwise buy a new pair as thay have probably a stretched wire that is causing a loose connection and aren't worth repairing.

Sound in left earbud shorts in and out

If its not hard to open the case, just solder the connection again (only if you found out that the problem is inside).
Also check the wire if it have 100% connection. You may also check skin of the wire. If found out no good, so possibly this could fix the problem.

My left earbuds on my JVC gummy earphones went out.

I have this problem all the time with my JVC earbuds. This may sound a little gross but it will work. I put the ear phone in my mouth and **** on the end of it pretty hard. What I have found is that sweat or even wax will plug the little hole and prevent the sound from coming out.
