1pair 40mm Headphone Speaker Driver 32ohm for Bose QC45 QC2 QC15 QC25 QC35 QC3 AE2 OE2, Studio 2 Studio 3, Solo 2 Solo 3, Kraken 7. 1, Akg K55, Marshall Major 2 Headset Replacement Speaker Part

I bought these for headphones I built. Coupled with the passive resistors I included, they're great. A little hard to drive--I recommend a cheap headphone amp with them to really make them sing.

Great upgrade to my smh-10 helmet speakers. Definitely louder and worth the upgrade. coms can now be heard on the freeway

Just installed these on my Bose QC25s. I had tried a method shoving bits of paper in the speaker in the past that helped the problem temporarily but eventually the speaker went fully out. Buying a new pair is expensive, and frankly just feels wasteful.I was a little cautious after reading some reviews that sound quality wasn't the same but i havent noticed a difference at all. Installation was pretty straightforward, youll need a soldering iron, hair dryer, small Philips head, and glue (i used super glue) this was my first time using a soldering iron and i didn't have any issues. Sound quality and noise cancellation are the same, and for the price i would say i came out ahead.

Had a speaker go out on my son's Audio Technica ATH-S700BT headphones, it made the headphones sound like the balance was way off to one side and no bass whatsoever from that dead speaker.Searched around for a decent replacement 40mm speaker @ 32ohms, which is what the original speaker tested out to be on the meter.Found these and the overall ratings were good, thought I'd take a chance on them.Item arrived right on time and speaker slipped into the housing ever so slightly loose, which is actually a good thing. Bigger would have been impossible to fit in the housing and most likely distort the frame which would have ruined the sound.A little hot glue around the edge of the frame and speaker, soldered in the wires and put it all back together, the sound is a perfect match with the other original speaker! I had already figured I'd have to change both to get the sound balanced, but its exactly the same characteristics as the oem speaker.Just an fyi, if you plan to replace your speakers in an AT headphone like this model, you'll most likely need a security torx or allen driver to remove the 3 screws inside. You can also try some jewelers flat tip screwdrivers,which is what I ended up doing since none of my bits would fit those screws. It wasn't that hard to remove, but be careful not to slip and poke a hole in the speaker when re-installing it.Overall, I'm very happy with how this turned out! These were not cheap headphones, and having to throw out over a hundred bucks worth of headphones is ludicrous! We'll see how much longer these last now that it has a new speaker in it, at least I have one more I can swap out if it goes again!

Have Sony headphones that were my dad's that he purchased in 1964. Turned out they had an issue that required replacing the driver's. Found these with good reviews and decided to give them a try. Only warning they give is not to overheat the circuit when soldering. Replacement went smoothly and they sound much better than the original drivers. Would highly recommend these for your next headphone driver replacement project.

One of the speakers on my bose headphones died and I didn't want to spend the big bucks to buy a new headphone set. Brought this speaker to my electronics repair guy and he replaced it in about 20 minutes with minimal cost. The speakers were really inexpensive and seem to be the same quality as the original.

I bought these to replace one of my QC25 speakers. After replacing the broken speaker, I noticed the new speaker sounded different from the old one on the other side, so I replaced the other one too. Fortunately, both new speakers work properly (with and without the sound cancellation function turned on). Unfortunately, the new speakers are low quality when it comes to sound/audio fidelity. The sound is now flat and muddled. The bass is too loud. They don't sound anywhere near as good as the original speakers that came with my QC25. In fact, they just don't sound good at all really. That said, the speakers do work, and the price was cheap (about $20), so I'd recommend them for a short term replacement until you can buy a new headset that has good sounding speakers in it. PS: if you plan to buy Bose then know that they release headphones with speakers in them that have a design flaw such that a speaker dying within a year or two is relatively common and possibly even likely. Buy a different brand.

I replaced my Bose QC25 driver after it went out from a decade of happy use. Soldering this driver back into the headset was probably the easiest part of the overall installation, and it immediately worked and I could not tell a difference between it and the original driver still functioning on the other side. 10/10 would recommend replacing your driver instead of dropping $300 on new Bose
