With the WH-1000XM4, I am a Sony repair agent. The "wind rushing sound when ambient noise is enabled" is often due to faulty ambient noise microphones. These are located directly under the ear cup foams, right on top of the speakers. They are very easy to replace however spare parts are difficult to get. Shout out to JoesGE though, he has heaps of spares for all types of headphones and small accessories

The world need more people like you. We should repair our electronics, instead of just throwing it out, when something is wrong with it. Often it's just a minor thing.

You can check the polarity of a speaker by applying a small voltage. If the polarity is connected correctly, it will push out, if wrong it will pull the speaker in.

I like the "figure it out" tinkering aspect. Sometimes things are just junk and honestly not worth repairing, but tinkering anyway can be its own reward, and you can use those skills to work on things of more import. Kudos.

Lol the binoculars issue is very familiar to me I was having this issue with my oven where it wouldn’t turn on randomly or would turn itself off after a short while I tried everything deep cleaning it slamming the door or gently closing it Tried putting something infront of the door everything you could think of i tried We were just about to call it a write off and get a new one when I had one last go at really scrubbing the pin and socket that latches the door closed and tells the oven it’s ok to turn on when I realised the pin itself had just come unscrewed slightly Itd been a couple months of frustration trying to cook anything Almost several hundred pounds to get a new one And all it was was a screw thatd came loose All that hassle and it took five seconds to fix And here we are a year later and it’s still working perfectly

I'm no techie at all, but I really enjoy your powers of deduction, how you find and fix faults, and ultimately the little squeals of delight when you do so.

Spent a life time fixing electrical things, from tiny escapement to 2000 hp motors . So I enjoyed watching someone else, fight such problems . Take care.

Hey Vince, here's a handy trick for determining a speaker's polarity. Take a 1.5v battery and connect it to the speaker terminals. Observe which way causes the cone to move outward. Remember the battery's polarity. That's it! Getting this right is crucial for optimal bass performance, so be sure to pay attention to wire orientation.

Why is no one asking how you got the products from Amazon? I just ran across this video so please be gentle if your a long time viewer and already know. This was great anyway I was literally glued to the screen. Very, very informative.

I follow you several years now, i could watch your videos all day because i find your voice and your way of handling stuff very calming and relaxing. And i just realized you're straight on the road to one million subscribers, that is terrific and well deserved! All the best and keep going with that great content!

Company utility truck - has a big camper on the back for tools - eliminates your view out the back window of course. I hated not having a rearview mirror anymore, just big sideviews. Saw those rearview dashcams on Amazon... can't live without it. LOVE it. I bough the 'Wolfbox' brand. Cheap, but it sure works great. Great seeing behind me again and it's even better at night than having a mirror.

Your enthusiasm, curiosity, and genuine enjoyment won me over... Subscribed. Interestingly, you managed to tap into my own affinity and long forgotten desire to take things apart and try to fix them. thank you 🙂

PCBWay is great, a genuine Krups part for my coffee machine was 20 euros, I got 10 of them from PCBWay for $5, and populated one of them with parts (the ones that tested OK) from the old board and less than 3p of components from my parts bin

You could maybe solder that gearbox to keep it together.

Hi Vince! For the correct polarity of the speaker. Briefly connect an AA battery across the speaker terminals. The cone should move out to denote the (+) side.

Love this kind of video. I usually only try and repair things I don't mind throwing away because they rately get fixed or go back together but I have fun with it.

You're right to side-eye random software like that. I have a VM I can blow away at any time for when I need to run software like that, which isn't often, but isn't zero times ever either.

34:45 Vince has a 3rd hand now! 😁

I just want to say that I love your channel. We live in such a disposable society now and I think it's great that you fix stuff. It's also super satisfying when you something to work.

Personal experience: The Wolfbox is an awesome rearview camera mix. I have one wired up to BE the rearview mirror for a vehicle that has no rear windows. This allows my work truck to have rearview as well as the security of having the dashcam. Those Blackview phones are just imitations of better phones. That's what the camera thing is all about.

Quick tip vince - to find polarity of a speaker, simply use a 1.5v battery across the terminals - check which way round pushes the cone out - make a note of the polarity of the battery - job done (it does matter which way round the wires go as incorrect polarity will affect base.

I wonder if it would be worth it to float a little solder on each of the tabs of the camera's motor housing to make it a little more solid?

To test the night mode of the game game camera, just walk through your garden after dark. It should certainly detect your presence. It may be the IR array is not being turned on or perhaps just a broken wire / loose connector. Enjoyed the video!

I know iPhone's will boot loop sometimes with a dead battery but you are right that could just be a firmware fault and not hardware, had a ton of fun watching this video... also, how do you get these amazon returns? this looks very fun to do

Regarding the first speaker, I believe the one who returned it for a refund was not happy with his purchase and cut the speaker leads in order to complain that it wasn't working when they got it. Many of that going on for those that think they want an item and then have instant regret after the purchase.

hello the phone batteries may be deeply discharged. Certain phones cannot recharge the batteries if they are too discharged what would be necessary is to check the voltage of the batteries if they are too low it will be necessary to recharge them up to 3.7 volts no more with a laboratory power supply

Hi Vince love the channel. How can I buy a box of "faulty/ returned" items such as you did for this video?

Lucky you - the last time I bought a job lot of faulty electronics someone decided to "decommission" them by snapping all the circuit boards into 2 or 3 pieces...

Ive never seen one of those tiny tactile switches taken apart. Your comm sense and creative ways of repair has resulted in me subscribing to your channel. Very cool work. Im not sure if you use a Hakko but what tip is that you have on your iron? I need to invest in one. How much does a box of returns like that cost?

"Positive" is always on the left if you stand the driver (speaker) on the motor (magnet). With one driver you're correct and there's no worries about phase issues unless you link speakers I suppose.

I was just looking to waste some time and I came across your YT. In fact I thought it would be boring, but I was totally fascinated by it. Thanks!

I loved this video! Like Sherlock Holmes of electronics. I was also genuinely excited when you figured out the binoculars. Also, Hugh Jeffries from Australia is a great resource for the phones.

Love this content Vince, looking forward to the next one.

34:40 - Vince suddenly grows a third hand! Great vids Vince, been watching for a long time, especially the Rolls series.

lol I found epidemic electronic today for the first time and now seeing it in the video is quite funny. really enjoy your videos. have learnt so so much!!

Thank you for taking apart my binocular model, i will refer to this video if I need to repair it.

I could see that on the binoculars, one side had jumped out the grooves to move it up or down as the other side it was sat in the grooves.

32:23 this is a common fault/problrm, its a high pitch whistling sound that has something to do with the microphone that is mounted right above the speaker when noise cancelling and ambient sound is on, some reports say its caused by moisture, hope this helps and hope you find a fix 🤞🏼 please look into it.

Oh man, what a pleasant video to watch! The JOY when tinkering the binoculars is unmatched!

Make more of these idk how I never came across you video, alogorithm matters. Keep up good work.

Wow, what a cool selection of items to look at =D Some great fixes too Vince!

I wouldn't put it past some buyers that they would actively damage the item prior to returning it as "defective" so they don't have to pay the return cost, as opposed to when you choose the "I changed my mind" option or "bought by mistake" etc.

this was a very interesting and awesome video! I really did enjoy seeing all the different products and the way you solved them was Amazing :).

I keep seeing those small binoculars at the thrift stores. I've been wondering how they actually work. Perfect timing for this video. Explains exactly what I was looking for

The xm4's are known to have an issue where they make a loud screeching sound in noise cancelling mode, due to humidity and condensation in the microphones. Maybe that was the issue with the ones in your video? Mine have this issue, would be interested in seeing if you could find a solution to the problem.

On those Sony headphones, check for condensation inside the ear cups. Condensation on a mic diaphragm can make the noise canceling go a bit crazy.

well i like to tinker with broken things and i really enjoyed this on a Sunday afternoon, thanks and new sub

I really enjoyed the binoculars.some pretty neat design work there.simple but affective

A windshield repair kit might fix that mirror well enough. (It fills the cracks with a polymer that has the same refractive index as glass.)

Maybe you can hold or press the buttons as you connect the USB to the PC to keep the connection going. I had to do that when i needed to update an firmware on an bluetooth speaker.

I have those Sony headphones and I love them. You're right that the noise cancelling is amazing.

I have had one of those vices for years now, If you dampen the surface you are useing it on like a workbench or table top the suction cup at the bottem works realy well and it should not move as much, just thought you may like to know.

Thanks for the I Geek camera fix, I bought one from Amazon,,, with the solar panel, it worked for around 3 days, then would not pan up/down like your one. Exact same fault, getting the locating/fixing lugs back on again is not easy plus theirs not enough length on the lugs to hold it tightly, I got out my spot welder on full blast and blitzed the lugs in welds. I;ve done the same with the rotation motor, didnt take this one to bits, just spot welded it. All good. I had gone through the process to have anoyher camera sent as a replacement, the seller sent me a new one but did not want me to send the broken one back (more than likely Knew about this fault) So I got one for free. I'll do the same with the new one. Cheers Ray

Absolutely enjoyed this Vince great selection, can’t wait for the rest of the items… I’m really considering getting a box of returns for myself 😊

Thoroughly enjoyed this video, great work 👍

The dash cam rear view mirror is amazing. Had one for a few years now!

One thing I do is save the electronics out of anything , including kiddy toys for things like that little switch you found broken in that alarm. I ended up breaking into a toy my grandson had to fix another he really wanted working again. I go to resale shops often and will pick up electronics for cheap. Now days, with the cost of replacement parts on some items, its best to have a box of parts available. I hate waiting for a parts order and would rather just swipe parts from a dead unit. I tried fixing a trail camara once, it turned out to be a loss. I tried anyway. Good video! Feel free to make those type of video's anytime.

Where do you buy these Amazon returns? Once you fix these things, where do you sell it? Thanks!

Love this. I worked in electronics for a long time before I switched to computers. I have the same spatula and almost the same vise 😮

Really good video, man! For the cellphones I would recommend having a laptop with no important/personal data where you could download and access those dubious software and websites

the blackview phone is definitely a software issue , when you flash it via software on your pc, the computer will hold the usb connection live until its finished flashing the software then drop the connection.

Bit surprised to see you install the software for the security camera on your phone after not wanting to install the Blackview software. I wouldn't trust the camera on my network either without it being on a separate VLAN.

Excellent video, as always. Nice come up with those headphones.

Dinner’s ready! 42:08. A repairman after my own heart. I am happiest repairing things too. Make way, new subscriber coming through!

Should stick the trail-cam in your dads back garden, that seems to be a hotspot for random wildlife, and not so wild life 😁

This vid inspired me to try and fix my PTZ Camera. Mine would pan up but not down. I was not able to fix it but mine seems to have been way more complicated inside. And while I was at it I found something interesting. My cam, like yours, has 2 antenna but only 1 is attached. I thought maybe it was broken but no, the MOBO itself only has one connection for it. The other antenna was still wired, but the wire was super short and just glued into the case, but otherwise not attached to anything.

just came across your channel great video, keep up the good work !

What fun!! I don’t know how to solder so I haven’t been able to fix things I’ve taken apart where it was clear a wire was broken off. Will try next time, instead of tossing.

Great watch as ever Vince 👏🏻👏🏻👏🏻👏🏻 I'd have added solder to those failed clips on that little motor as well as what you did 👍🏻

for the binoculars, the push thingies goes into the slot of the slider.

When soldering the wires to the speaker...check the polarity with a small (AAA or AA) alkaline battery first. BATT POS to Speaker positive (RED) / BATT NEG to Speaker neg (BLACK or WHITE) should push the cone out. Not to be done for an extended amount of time...just a quick check to make sure the wires are soldered correctly vis a vis polarity.

Managed to watch a few minutes of this, but I'm afraid KZfaq has become unwatchable now because of the number of adverts.

great video! how much did you pay to get this box of returns?

Vince, how and where do you get these little boxes of treasure? What's the approximate price for a box like that?

I Geek camera. Seeing just those 4 gears reminded me on repairing my quartz clock movement. Bought in 1991 with a Westminster chime to add to a brass carriage clock. It died in 2021. So looked for a replacement, but non like this German one, now all the speakers are not internal like this one. Time for a fix. Took lots of photos of disassembly of many cogs. All that was left was a circuit board and speaker, plus the drive motor. Connected it to AA battery and motor dead. Then discovered no power exiting the quartz crystal. Had to buy 10 in a pack. Very fiddly job soldering this little tube in place. Anyway replaced all the cogs with a wipe of silicon fluid. It worked and now today still working like new. Well pleased. Love your channel as before knowing have fixed lots of stuff, mostly electronics.

Brilliant video , I love this kind of content , subbed 😎👍🏼

Hey Vince, where did you buy those? Directly from amazon or another website?

We also learned that Vince has three hands, (phone repair) haha, no wonder hese so good at fixing things haha Brilliant video as always, thanks Vince.

I have one of those dash cam mirrors. Same company. I love it. Great resolution.

Great video by the way i have learnt a few tips in the process Another Sub added Thank You for sharing !!

what a great hobby. Where did you get the return package? I would love to try my luck with these :D

How does one go about buying returned items from Amazon? I’m also someone that really loves troubleshooting and fixing electronics. Would be a lot of fun if the price were right. Hopefully lots of broken things.

The ptz camera motor is an off the slf stepper motor you can find everywhere. But all the fun is in repair 😅That's what we're all here @ MMV ❤

Have been fixing stuff like that since I was a kid, 50 years ago. Very nice. Broken cassette deck, kid opens it looks at how it works, fixes it.

Love the videos, sad thing is although Amazon have a dispatch centre in Australia, I believe we're too stingy to send stuff back so no mystery boxes in Australia except for fake ones on ebay. As to the Sony headphones I was lucky enough to pick up a set for 5 dollars op shop wise, and your right you get the buzzing if it's not set right but it's very eerie noise cancelling wise because your right it's dead quiet in cancellation mode. Lovely video again Vince very watchable and great to see all the good stuff Amazon put into their English mystery boxes. Also I may be wrong but on the white lead mount on the speaker there is usually a plus sign in the plastic. As to making a difference, I would think it would because you want the speaker to push out in the right part of the sound sine wave, which means positive it pushes out, and if reversed some audiophiles say even a single speaker will sound different, but I'm usually wrong.

Hi Vince, could you please let us know where you bought your Amazon returns from? Is there a specific websit? Some years ago I bought a 40ft truck load of customer return bikes from Argos via there trade website, and about 30% of them were unopened and brand new. After that I bought about 500 telephones from them.

You did a very good job with the binoculars. I work with optics all the time an yes I was telling you or the screen how to do it 😂. Much respect for jumping in it and figuring it out. A lot of times the lenses will come off like a pop bottle top. But be careful and dont squeeze cause most binoculars are made from thin and light aluminum.

Re mirror cam, these are really popular with van drivers, as you can set the rear cameras to default display….that way you have a rear view mirror, even though you have no windows.

About phones. For me 5V 0.3A looks more like a hardware issue, battery have to be charged at least 1A, and anyway even at 0.3A ,after 1h, it have to hold charge. I think there is a short on the MB in one of the power rails

The spring sticking out of the back of the Yale door/window contact is a tamper switch. You stick or screw the mounting plate to your door or window and if anyone tries to tamper with it by removing the door contact it will sound the alarm. The spring just applies pressure to the microswitch keeping it pressed in.

A phone charging like this means the battery is flat. The charge controller tries to safely kick start it by applying a little current until it comes back to life. It may take 2-3 hours depending on how much juice was left in the battery. You can't turn on the phone nor see any indication on the screen while it's in this state. Once the battery come back to life (if it ever does) the screen will come on and display an image of a battery. You still have to wait a bit until it changes to at least 5% before you can turn the phone on. The USB issue is related to this aswell. The USB controller chip is powered by the USB port and it initialize itself so you hear the connected noise but then it tries to talk to the phone to actually transfer data to the computer - you can connect to a phone that's off to recover data or flash the software. It can't come on since the battery has no power so the USB controller resets, that's the disconnect noise. If the battery has power then the charge controller is faulty.

The only HW fault behaving like a SW issue that came to my mind is a broken decoupling capacitor on a processor supply, allowing too large ripple on the supply, yielding erratic computer behavior. But most often these devices do not use just a single capacitor on a processor supply, so just one broken won't immediately cause such issue...

With the binoculars... all you do was lift up the fork & drop it back over the pin on the lens slider. Look at the video before you take it to bits. One fork is each side of the pin, the other fork is completely behind the pin. 12:17. Yes, I was shouting at the screen 🤣🤣

How do you buy these Amazon customer returns boxes I would love to try fix some things like this 😊

These videos are joy to watch!

Nice repairs! Not needed in this video, but a 3D printer have helped me fixing several things in my household, where I have printed plastic parts like gears for mixers, broken retainers etc. I'm new to your channel so don't know if you have one, but it might be a good investment :).

With binoculars, what you should have done was lower both sides to their lowest point before snapping them in

Hey just want to say thank for the content! And I’m wondering where you buy these boxes? There are so many scams out there… 😊

I like how Vince prefers hardware based faults over software based faults! I'm the exact opposite. I have fixed too many software problems on devices to count, but only fixed hardware faults that I could find tutorials for the exact model and exact problem for my devices. This is why I'm watching Vince, because he understands circuitry and explains things in a way that it's understandable! He's showing us all how to fault find and repair hardware faults! If I understood hardware on his tier, my next step in life would be learning to write my own drivers so I can create my own circuitry!

I have just stumbled upon your channel and really enjoyed this video, in fact I might even buy a box of returns myself! A new sub for you. :D
