Question about Bose Radio Communications

1 Answer

I have a Bose Quietcomfort 2. There seems to be a loose contact on the left side of the headset. It doesn't help to re-insert the jack or replace the battery. I would like to open the left side to see if I can fixt it myself (solder or other solution). My question ... how do I open it without twisting, forcing and damaging the headset for good?

    Yes I was now able to open (even without having to cut the soft-part). I also went on taking out the 4 screws to open the outer-lid. However I cannot see any visible damage or loose wires (however tiny they are). It still doesn't work, so it may be the loudspeaker itself that is out of order. I guess my only option is to buy a new unit ... as Bose stores don't seem to accept repairs. Your final opinion on this may be helpful. Thanks.

In the large number of cases, the head phone cushion is the last piece of the headset to be put into place, often with glue or some other bonding agent.
To get into the area you are speaking of, you may need to perform a slight 'operation' on the left heaphone to gain access including, in a worst case scenario, cutting the ear cushion, just make sure you have an epoxy resin or some other form of glue or bonding agent that you will be able to use to put everyhing back together with.
I hope this helps. Good luck.

    The best way to test the headphones is to use a multimeter and test the continuity (aka, the beep test) from the plug that plugs into the stereo to the wire inside the headphone. If the problem is interrmittent you may need to wiggle it around inside the headphone to see the fault.

    If you can see point of contact from where the wire meets in the headphone, as long as you don't over solder it, you can apply a small amount to ensure the contact has clean fresh solder as a dry solder joint may cause this intermittent problem. I hope this helps. Thanks for the rating as well.

Raven01@Hi, The left hand speaker has snapped off the head band on my bose qc2. Also, the blacl plastic that hold the headband together above the right speaker is coming apart. Can I buy a replacement...

No, Bose doesn't cover any damage done to products that is any fault of the buyer. You might be able to if you contact a Bose retailer and special order it through them. Just a note, it will cost you more for the new speaker due to it being a special order. Probably around the lines of 40-50% of the original sales price (which is outrageous). If I were in your shoes, I'd try to find the same unit on craigslist or Ebay.

The right ear phone doesn't work but the other one does

check that the wiring in the plug is not broken. if you pull the plug out a little so that one contact in the jack contacts both sides,you will hear the dead side come on. If it does not,the wire is either broken in the plug ,or where the wire goes into the headphone.

I have lost sound in the left earcup of my Bose QC3 headphones, although sound comes from the right earcup. How should I proceed to fix it?

The solution to this problem is not for the faint hearted. You will break your headset, you will void your warranty, and you quite likely will end up with a non-working headset. You will also have to solder very small electrical components.

I also had the left channel audio not working, so the first thing to do was to take apart the headset.

Step 1. Remove the battery. Remove the two tiny screws from under the u-shaped plastic piece that holds the earpiece to the headset. You will have to pop out the end furthest from the audio jack. A #0 phillips is needed. Put the tiny screws in a safe place.

Step 2, Break the silver cover free from the black plastic earpiece by sliding a flat blade screw driver down between the joint towards the bottom of the earpiece. Be very careful not to insert the screwdriver blade too far into the earpiece because the circuit board is just inside. For some reason Bose decided to glue the two attachments for the bottom of the silver cover to the earpiece.

Step 3. Unscrew the 3 screws holding down the circuit board and put them in a safe place. Gently pull up the circuit board about .5cm. Look at the audio jack, the tab on the circuit board on the bottom right is the left channel audio. You can try to reflow the solder at this point on that tab using a 25W iron. It didn't work for me, but if your connector is not as bad a mine, it might work.

Step 4. Remove the solder from the 4 tabs holding the audio jack to the circuit board. Remove the audio jack from the circuit board (this is hard and accompanied by much cursing). Try not to overheat the board and lift the lands. Use a pliers to pull out the contact for the left audio channel and bend the jack contact out 1mm or so. Insert it back into the audio jack. Get your audio cord, plug it into the jack and check and see if you have continuity with an ohmmeter. If it all checks out, continue on.

Step 5. Resolder the audio jack back into the circuit board (also accompanied by much cursing). Screw the circuit board down. Put the battery back in and see if everything still works. If it doesn't, check to see if you broke the fine wires just above the audio jack on the circuit board. They run to the other earpiece through the headset.

Step 6. Reassemble everything and see if it still works. If it does, then congratulations and enjoy your restored audio. If not, open it back up and look for broken wires.

Disclaimer: This solution will likely destroy your headset. Proceed only if you have experience working with modern surface mount parts. I am an electrical engineer with 30 years experience in troubleshooting and repairing electronics and it still was not an easy fix. Total time to repair was about 4 hours.

Only left earphone is working

You should return them to the place you bought them. They should be able to sought the problem out. You might need the sales ticket. Or visit the Bose website. They should have telephone number helpline.

Loose connection in Bose headphones

Cut the ******** and replace it with a new one. You will need to solder the wires on to the new one. Keep the old one, cut it open and it will tell you which wires go to which terminal.

No Sound/No Power

I used your site to research the problem further. I found an answer which recommended rubbing the suspect terminal lightly with a pencil eraser. It worked! I now have battery power and my headset works fine.

Less sound on one ear than the other

Yeah, based on all of your problems, i would safely say that you have a blown speaker. Call up Bose at 1-800-999-2673. If the headphones are under warranty (1 year) they will replace them for free. If now, they will charge you $100 for a replacement pair, which is quite a deal considering that the headphones cost $300.
