Question about Sony MDR-NC6 Consumer Headphones

MDR-NC6 Sony Noisecancelling headset

The audio in the right speaker has died. The noise cancelling still works on both speakers. There is no visible wire stress, breaking or otherwise, and the casing appears all intact. Any ideas?
Sony's repair charge is equal to getting a refurbished pair. I could probably take it apart if that is suggested.

    I'm with you. My sound has also simply gone away in the right speaker. I've taken it apart, but I have no idea what I'm doing. Any suggestions?

    I have the same problem but it's on the left side, weirdly enough. Any thing I can do? I fear it's too late to return them, the receipt and packaging are long since lost.

  • theTONIC Aug 14, 2008

    My pair was working fine and then the right speaker just went out. The noise canceling works in the right ear but not in the left. Weird.

    I too am having the same problem. There is no apparent damage and I stymied. I will eagerly await a solution with the rest of you.

    Same problem - left ear. Cable connections seems to be intact internally and otherwise.

  • pmetelski Nov 04, 2008

    Same problem. There is no crackling when I wiggle the cable, so I don't think the plug is damaged. Plus, the other speaker works just fine. Any solutions?

  • ianpstark Nov 07, 2008

    Well, my problem is similar - the audio in BOTH ears has gone and all I get is a hum, as though it's just the sound being picked up from the noise cancelling mics - I'm guessing this is the noise cancelling working. Also no crackling when I wiggle the wire. I opened them up and couldn't see any loose or broken connections. Any help appreciated as over 6 months out of warranty.

    I have the same problem. Right head phone is dead and no obvious wire problems.

  • Anonymous Jan 19, 2009

    Same here everyone. The right side is dead. No ripped wires, no nothing. I don't use the headphones all the time either so they couldn't have just burnt out or something. Not that old about a year. Anyone with a suggestion on how to fix this please post thanks..

    Same thing here. Had them for two days, didn't even get a chance to enjoy. The right speaker just cut off completely, even the noises. No reaction to jerking the wires or anything.

  • Anonymous Feb 20, 2009

    Just had them for two days. The right side quite unexpectedly cut off, including the power-on noise. No obvious wire problems.

  • jlmoulton496 Apr 22, 2009

    I do not get stereo out of both sides. I get sound out of both sides but it is the same track. It sounds out of phase.

In the off chance someone (like me) was hoping to resurrect their set of MDR-NC6 headphones, I'm going to echo what slon_vitaliy discovered in his/her solution - the right speaker died. Unlike some of the other posters here who said they had no sound but they did have noise cancellation, I had neither. I disassembled the right cup and started testing the wire connections. All were fine. I finally narrowed it down to the speaker wires and then the speaker itself. Like slon_vitaliy, I ran a second spare speaker in parallel with it. The second speaker started playing music.

I also have no idea where to get a replacement speaker. Time to treat myself to some new headphones...

I think I have it. I've only had a chance to listen to a couple of songs till the brand new headset's right ear died. I took it apart and found that when I hook up another speaker in parallel with the dead one, it works, which can only mean that the circuit is fine and the 'dead' speaker is really dead. No idea where to get a replacement though.

I developed the same problem after 3 years of use. I took the thing apart and checked the continuity of all internal cables. In my case, I had no audio from the right cup, but could hear the white noise whtn I turned the NR on with no audio source connected. Here what I found.

The 4 conductor wire which goes from LEFT to the RIGHT cup is very flimsy. Usually the black wire or the green wire takes a lot of stess and breaks (where the cup slides in the headband). There is unfortunately no simple way to fix it. You have to take the whole thing apart, de-solder the cable, find a replacement cable (difficult) and re-solder all 4 (red, green, black, ground). I plan to drilling a small hole to run a diffrent cable to fix my problem,

I have a pair of philips SHN-9500 noise canceling headphones and the left speaker is not working how do i fix this?

Unless you are really good and have the correct soldering gear, I\'d sudgest taking it to a repair centre. If you are going to have a go, you need a variable temp, needle point solder iron, a solder \'sucker\', a magnifying glass and a steady hand. The wires to each side are in s single unit. Here is a break down, from the centre, + then insulation,then the common which is rapped around that with another layer of insulation. Good luck!

Left Ear cup not working.

Either ship them back to manufacturer if still under waranty or you'll have to re-solder the wiring to that speaker if they have become disconnected or yanked accidentally of which the leftside is usually where the headphone cable first enters in the left side.

Severe squelch in left ear phone

The design of these headphones includes a microphone on the outside and on the inside of each earcup. The outside microphone detects outside noise. The inside microphone monitors what you are hearing and when it detects that the outside noise is present inside, the active noise-canceling circuits remove that noise. This happens fast enough that you perceive a significant reduction in the outside noise getting to your ears.

The airspace inside the earcup is a tuned chamber defined by the shape of the foam in the ear cushion. This is important because with the inside microphone in close proximity, but at a 90-degree angle to the speaker, the circuit must be designed to eliminate the normal feedback that occurs.

If the foam in the ear cushion has weakened/deteriorated to the point that it no longer has it's original shape, (in particular the lower half of the ear cushion), the size and shape of the air chamber inside of the earcup is directing more of the speaker sound toward the microphone than the design can compensate for causing audio feedback to occur. You are hearing that feedback.

On my QC-3 headphones, I can cause the feedback squeal in both earcups, with the left earcup being more sensitive to the shape change than the right.

It is probably time to replace the ear cushions. If so, they are available from Bose for $35/pair.

Riley, it could be that the membrane on the cone of the speaker is damaged, if that were the case, then you will have to replace the headset with a new one; also check the wiring to the speaker there may be a bad connection to the speaker, if that is the problem, it can be solved by soldering the connection back to the the speaker. you can also squeeze the cord starting from the bottom and slide your fingers up the cord, listen through the headphones for any break inn signal, if that happens,cut the wire and re-splice the wire and tape the wiring with electrical tape. good luck.

Can bose QC3 work without noisecancelling/battery?

No, the audio input must go through the active noise-canceling circuits that drive the speakers in each earcup. The noise-canceling circuits require a charged battery to operate. Unfortunately, there is no way to bypass these circuits and drive the audio input directly to the speakers.

Cat chewed through right speaker wire that supplies right speaker...tried sawdering wires together...still no there a special way to connect these??? thanks

Look carefully over the entire length of the wire for any puncture or crushed insulation. Cat teeth, especially kitten teeth, can exert needle-like pressure that could sever the wire without leaving easily visible damage. My rock-headed cat does this too.

Almost universally, a red or green colored wire is (+) and a copper colored wire is the ground (-). Make sure the same colored wires are soldered together.

The best way to repair headphone wires is to offset the solder joints of the (+) wire and the ground wire so that they don't short circuit. Inotherwords, don't have the solder joints opposite of each other so that they might touch together.

A good quality shrink tubing should go over the repair to relieve stress on the soldered joints. These wires, by the way, are enamel-coated and need to be tinned with resin-core electronic solder before joining and soldering the wires together.

Don't breathe the fumes when soldering and wash your hands after you are done handling the solder.

I have Sony MDR-IF140 and the left phone has stopped working. Right one is fine . Will I need to buy a new headset?

That generally happens when there is a break in the cord or if the device is set to mono. If it is a break you could patch it if you knew where it was otherwise you'll want to buy a new pair of headphones.

One side of my Bose quiet comfort on ear headphones isn't working...can you help?

This is a problem that has to do with the wiring of the headset and any attempt to open it up to work with it may damage your headphone further.
It might require you to open up the part that doesn't function and ensure that the wires are properly connected and to make sure they are not jamming one another as this can cause failure in the speakers.
If you are able to go through the wiring and there is nothing wrong, it is therefore the speaker at that part of the headset that is not working and has probably exceeded it's lifespan and needs to be changed.
If you do not want to go through all these stress, you can send it to a technician.
please comment if you need more information.
