Opening bose on-ear headphone speaker's cup

Hello,
The left speaker of my Bose on-ear headphones is intermittent. I know the problem is not the outside cable, it come from inside the cup. I tried to open it, but after removing the foam and the two screws hidden behind it, there's steel something preventing me opening the back part. I'm not sure if it's a hidden screw or a clip, I'm a bit afraid to use strength. Any idea on how to open them?

Thanks for your help,
Louis-Philippe Giroux

There are four screws that hold the cup together. Two at the top and two under the foam that goes between the ear pad and the plastic cup. Once I removed the four screws the cup and speaker came apart with no problem. Of course I did not see any issues with the soldering, so I have a bigger problem.

Apparently there are screws hidden in the small foam ring covering the plastic (not the earcushion). Try it removing the foam and tell me how it goes!

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.

Hello, I just got a Bose QC3 on eBay. It works fine except the cable which is not the original one but a one from T'nB and the left earpiece has a very annoying whistling noise when I press it or even...


i would buy a new ear cup.and a new battery. and perhaps a new cord.
i had a problem w/ my ear cups and i noticed that when i bought the new ear cups the sound was better.
i also read that if the battery got alot of usage (4 plus year) then the whistling noise comes from that. i'm starting to have the same problem. i have had my headphones for a long time. i think like anything else that operates on batteries its time to change it.

I have the same problem. The first one that I bought last 1 year. I bought another one and the same problem has appeared today. I think this is because they are assembled in China. Cheap and low quality manufacturer that is sold at very high prices.

Bose QC3 makes a high pitch noise when i press it against my ear


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 siginficant reduction in the outside noise getting to your ears.

The airspace inside the earcup is a tuned chamber defined by 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. When you press the earcup close to your ear, you are changing the size and shape of the air chamber inside of the earcup thus 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. Removing your hand from the earcup should restore the shape of the air chamber allowing the circuits to return to normal operation.

If the feedback occurs too easily when you are NOT pressing on the earcup, then the foam may have weakened/deteriorated and it may be time to replace the ear cushion.

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.
