The problem was that the new driver didn’t have sufficient sound isolation from the microphone, which is meant to pick up passive noise. I could be just as wrong, but those capacitors and inductors could be parts of two (or more) switchmode power supplies, to create a symmetrical power supply from an asymmetrical supply like a battery, and possibly a separate supply for the digital circuit. I’d think it would be fairly difficult to suppress the local feedback from the speaker back to the microphone, and to provide just the right amount of power and phase shift to cancel external noise, over a large frequency spectrum, with just analog processing.
You could build an adapter cable with a 3.5mm jack and socket connected straight through, with 33 ohm resistors between the signals and ground. I just replaced my worn out earpiece covers for about $10 (ebay) and 5 minutes (following a Youtube instruction). Intermittent cutting out of the right side of my QC15s brought me here, I have to tap it to get it to work. I actually disassembled the headphones again and there aren’t any significant chips on the other side. Nice, its amazing how much useful stuff gets needlessky trashed these days because it needs a 2 dollar part.
As something between trashing it and fixing it, Bose will give you a new pair of QC15 headphones for $100 plus return of the old ones, at any time. You know, if you are going to sell headphones for 400 bucks, you’d better make replacement parts available I say. I’m an engineer for a company that provides In-Flight Entertainment systems to commercial airlines. I guess designing specifically for airplane noise can boost the performance of the system, but I find it hard to belive that a $3 headset can be very much effective in active noise cancelling. If you could point us to a consumer piece of hardware that rivals this hardware, in particular in-ear QC20i (sounds like what you’re referencing is an in-ear) — please let me know! In the photo on this page, look at the series of colored wires that are soldered on the right side of the board. First sorry about hit the report button on your question hope its better well ill share this your battery cleaned out right so I would say that its NOT touching each end the spring it might have moved this is on the open lid or your battery fluid got dried and know you must re move it stop am just sharing this I would get them looked at there is some one on ebay who repair base head phone and maybe he is the right place name affordable. I was recently travelling and noticed, what appeared to be, my battery had exploded within my headphones. The only reason I found it was that it happened right after i changed the battery which got me thinking about what could have possibly happened just from changing the battery.

Bose is king of Noise Cancelling Headphones, especially for music-loving business travelers.

Bose QuietComfort 15 inherit the excellent noise cancellation tradition of its predecessor.
An expansive inflexible case keeps the pricey jars sheltered in your stuff, and Bose additionally incorporates a plane connector. With the noise cancellation immediately, you will have a virtually silent environment by QC15.
I already have some sound testing; this Bose QuietComfort 15 deliver us the warm and lively audio with strong and clear highs bass.
While we like the general sound of the Qc15, we incline toward the more precise Denon, and we wish it were conceivable to listen without force.
As the Quietcomfort name intimates, to us at any rate, these earphones are significantly more about solace than a cool look, however. In my opinion, this QuietComfort 15 is not so beautiful but in design, they are still nevertheless brilliantly with more comfort and concessions.
In package box, we have the high-quality protective carry case with a replace cable and an airline adaptor.
This QuietComfort 15 is $50 cheaper than the QuietComfort 3 because there are no rechargeable batteries included in package box.
We need to distinguish the different between Cancellation and noise isolation, whereby the external sound is blocked by your earphones or headphones. With this design of Bose QuietComfort 15, the sound will be leaked a little than other fully-enclosed headphones.
But sometimes, the noise cancellation brings the less effective, especially talking to the female, even it does not entirely eliminate human’s voices, just making some affected to conversations. And if you’re looking for something to block out all of the noises from outside while listening to music or having conversations with a friend, this Bose QuietComfort 15 is the best solution.
Because of the basic material science included, the Quietcomfort 15 increment weight in your ear, a vibe that some individuals discover uncomfortable, prompting cerebral pains and queasiness. Bose provides the tricky assess range to this QuietComfort 15, with the price $299, these headphones are expensive for sure, but it worth for its price. There’s an intentional endeavor to make the sound warm and smooth, with a slight accentuation on the low-mids that can mellow music in a somewhat charming style.
Up against other prominent sets like the Beats Solo HD, however, the Quietcomfort 15 show much better adjust and a through and through more adult sound.

So whether you are after a full surround sound system, a new TV or a pair of headphones, you can be sure you are in good hands. These headphones have active noise cancelling, which uses a microphone to capture ambient noise and digital signal processing to insert an out of phase signal.
These were designed for a different set of headphones, but matched the impedance of the original Bose part. I have a pair of QC3s and after 5 years of fair use the fine plastic parts just crumbled and the pads skinned horribly, Still usable, though. The full-up system – servers, video displays, handset controllers, audio jacks, everything but the headphones because those are throwaway.
Would you be able to share any details about this In-Flight systems… like what is the perceived noise attenuatinon for each frequency range, where is the power supply located, MICs, etc.

I am repairing a pair of this headphone where the negative terminal in the battery compartment was broken off so I wanted to know if someone knows where the wire from negative terminal enters the main earpiece unit.
That is just plain old robbery for an almost built in failure point on a pretty expensive pair of headphones. I have no experience in soldering and glueing like mentioned above and frankly it is all daunting.
The broader range of frequencies will be blocked to reduce the background noise even you don’t play any music. Upper mid could be a bit merciless, prompting mellow audience weakness throughout long listening sessions. Their traditionalist silver and a dark outline have long been connected with the working class, center age demographic.
Customers spend more money on their trying, but, commotion scratch-off remains something of a corner, restricted to unreasonable on- and over-ears sets like the Bose Quietcomfort 15 and a sprinkling of generally disagreeable in-ear options. In the QuietComfort 15, amplifiers behind little grilles on the again of every earcup screen surrounding commotion. Engine snarls and the droney buzz of cooling units vanish making them ideal for utilization on trains, transports and planes. Nonetheless, in case you’re eager to forego the commotion scratching off and the basically delightful knowledge of wearing the things, better sound quality could be had at the cost. Have had some problems with feedback and my phone not recognizing them probably because they present a higher-impedance load than passive headphones.
I would be grateful for any description or a close-up picture showing the wire going in from negative battery terminal. But, if what you say is true, perhaps I can be inspired to push myself in learning and fixing the fatigued wire from the negative terminally the battery to the soldering blob.
Keeping in mind that is to the extent that to Bose’s promoting as their genuine look, they offer little of the elaborate style of the comparatively prominent Monster Beats range. Whether you incline toward a restrictive lithium particle result or the all inclusive style here is the purpose of inclination, however, its something to think about.
Simply strolling along a way, the degree to which they hose the noise of passing autos is truly noteworthy. On the other hand, such as splashing your proposed day by day admission of foods grown from the ground with a covering of sugar, its not out and out right. While treble clarity is great here, to a degree restricted determination and imaging prevent the earphones from entering the major alliances the value may propose they have a place in.
So I’m thinking about modding them so I can bypass the fancy active electronics when needed. I have little electrical engineering experience so I’m probably overlooking some obvious reason that would fail.
With that microphone signal the signal processor performs some trickery so that the result is a signal that is roughly the inverse of the amount of ambient noise that would pass through the headphones to reach your ears.
These headphones are very good in blocking outside nose to create a peaceful place for your ears.
