A wireless headphone released in 2014 by Sony.

How do you fix the broken swivel part on them?

I got them this last Christmas and I broke them around 2 months ago when my mom told me my dad had a cancerous brain tumor. I dropped them on the hospital ground when she told me and the swivel part broke. The chord is still attatched and they still work but the one side hangs by the chord inside the headphones.

Hello,

I’m also looking for this part.I contacted Sony France, and some parts distributors. For now, I haven’t good news to share and I’m still waiting.

I saw on Amazon lot of people who have the same issue as us.

I wonder if the parts of XB950BT and XB950B1 are compatible with each other. Do you know guys ?

Thank you for the topic and your possible answers.

Cheers

Hi guys I have this problem, if you undo the screws, remove the metal plate and snapped off piece and then cut away on the other end of the snapped piece (thays still attatched to the headphones) untill it's pretty much flush then scuff each surface you can just super glue the ear piece back onto the band, it's the only solution I can find, I'll update you if it doesn't work but it looks alright just means you lose the pivot function, but with the big squashy earpads I think the fit shouldn't be effected as long as you superglue it flat! (Once you do this though there's no going back

All that pressure on such a tiny plastic part - for shame, Sony, for shame. What a terrible design.

I bought a replacement swivel part on eBay but once I disassembled the headphones it was clear that unless you cut and splice that wire, and who knows how many tiny little wires it contains, it is for all intents and purposes impossible to remove the broken part and install the new part. That’s when I stumbled across this page.

I fixed my headphones by holding the broken side headphones in an aligned, “neutral” position, and by then drilling two tiny holes through the opposing swiveling parts. It was not too hard to maneuver a small hand drill with a very small 1/16” bit coming at the parts from the earphone side. The holes were drilled parallel to the direction of the headband. I then sanded all the faces with a bit of 100 grit sandpaper, slathered 5-minute epoxy on the faces, and ran a few simple stitches through the holes and the walls of the swiveling parts, and pulled/tied them as tightly as I could, drawing the sanded faces together into the epoxy. Space is tight in there so I used a small curved upholsterer’s needle, a pair of pliers to pull the needle through, and some very strong V-92 sailmaker’s thread that I happened to have lying around. (It’s similar to upholstery thread; not particularly thick but quite strong.)

The epoxy cured quickly as I did this and the stitches provide a little bit of extra structural support fairly near the outer edge of what had been the swiveling parts, so, they’re in a place where they can minimize any twisting effect of the headphones on the repair. On reassembly the faceplate completely covers the stitches, and even though the threads are sticking out a bit they don’t misalign the faceplate at all. Except for the loss of the swiveling function, the repair is invisible except for a thin line of epoxy on the inside of the band.

I opened the area up where the swivel piece is located and super glued it. I worked all of 2 hours before my son dropped the headphones and the broke again. The part I need is specific to ordering it...Really simple to repair, I just need the part. You might be able to go here to order the part. I'll check tomorrow to see and provide my results here.

Good fix Jaz. This isn’t a spam link - it shows very clearly how to drill through the two broken pieces with a 1.5mm bit (I think a 1/16” bit would work in the US) and use two of the casing screws to hold the broken pieces together. No glue, thread, or soldering.

Hi. Mine did not break at swivel. It actually cracked between exterior screws where the model number is displayed as if screws were fastened too tightly. I purchased a new bracket to replace left and only outside bracket that holds the earpiece. Will I have problems removing old and simply basically screwing on new bracket onto earpiece and in tact swivel? I mean this is the latest model and I notice plastic thin covers on the inside of each side of each "fork" that holds ear piece. Please tell me it's an easy fix....

It's not that simple to repair the hinge, as soon as you remove the screws you'll see that the wire is direct connected to it with no option to disconnect unless you disassemble it all

the wire threads through, is not direct connected, but yes you would have to take the earpiece apart to remove the wire and rethread it through if your could replace that one plastic part of the headband where the swivel is attached. Clearly this is a design defect (intentional - after ~70 years in the electronics business of course they know it's going to break there); as all the stresses upon the ear cup/headband connection is focused on a cylindrical area, narrowed from ~7 mm to 3-5mm wide, with a 1mm thick plastic wall. This obviously should be made of metal. I can only conclude that they intended it to break.

por

I should say that the wire is direct connected to components in each earcup on both ends. Makes repair more complicated, where a better design would have made repair completely unnecessary.

por

Yes. I got the part from ecopart,. After I received it, the other side broke. I had to essentially remove all connections from the motherboards, disassemble (a real pita) resolder connections. After all that, my left channel has no sound now. I have procured a new motherboard from ecopart, and a new headband with wires, but it is so needlessly complex (should have plug in connectors, and don't let me get started about the crap design of the swivel) I am not sure I want to invest another 2 hours trying to do it. Not to mention that the motherboard is visibly different, (different revision?) and I am not sure that it will work if I am lucky enough to do it right.

por

I have a pretty good idea for reverse-engineering a better swivel, but I am not sure I would want to take on the task of disassembling and reassembling with the soldering the units for people who wanted to pay for it. I am confident it would work though.

My 11yr old has this same issue. It’s now 2019 and it still going on, sad. He’s had and broken umpteen different headphones but as a twitch gamer these are by far his favorite, even over the more expensive ones. So dad the tinkerer and locomotive electrician has been tasked with the repair. Sony does sell the entire headband setup for around $43, google the model # and it’s the first hit. Of course I’m going to TRY to pull a 6million dollar man repair and make them BETTER!! I’m thinking I may try to get on my buddies CNC and machine the part of aluminum or maybe something even stronger. And since so many seem to break I bet I could do ok online selling them with good instructions and needed tooling. The thread and epoxy trick sounds pretty good but I hate to lose the swivel. I will report back!

Yeah mate just do what me and tpe2 did, there's no need to drill it out just use something to cut the broken plastic piece of and then superglue the earpiece back on (but you do lose the swivel function) I have had mine like this for over a month without any problem, be sure to use plenty of super glue tho and make sure the earpiece is in a neutral position!

por

I ended up doing this, thank you!! I used baking soda as a filler to get a stronger hold.

por

Would you mind sharing what you mean by using baking soda as a filler to get a stronger hold please? I am about to attempt to fix my son’s broken headphones. Thank you

por

Once the superglue is in place, dribble a little baking soda over it. This causes a chemical reaction with the superglue, making it very hard and filling in gaps. (Superglue by itself is terrible at filling gaps.) There are lots of interesting examples on YouTube for this trick.

My daughter handed me her Sony headphones in 3 pieces, both legs of the swivel had broken off - SONY! whatever happened to quality control? Anyway, gluing was out of the question as fragments of plastic were also missing. On Amazon, I bought a pack of 'mouldable glue' by a company called 'Sugru'. The pack contains 8 Saches, each containing a piece of 'putty'. Before opening a pouch, I had to remove the broken legs from the dangling headphone - (carefully remove the earcushion, it has a tacky base which will hold the earcushion again on completion, remove the 4 Philips screws and lift the cover). Pushed the broken legs out easily. Placed one broken leg in position and moulded the putty around the joint. The putty is a silicone rubber and takes 24 hours to cure. Then did the other leg ditto. I'm positively surprised at the result, and still have movement of the earpiece. Thank you Sugru, and I hope this info helps others. Kind regards Kerry.

Kerry would you be able to explain in a bit more detail what's you did? Getting lost with the pushed the leg out and put it into position and used the putty... would love to use your method as you still get the movement

What I did and has held up for at least 6 months now is to tape round the swivel, pushing the two broken parts together and then leaving a gap at the top. Make sure it’s in line and slowly fill it with gorllia glue. No the headphones won’t be able to swivel again on that side but it hasn’t made a difference to their use, the other side swivels and that’s enough.
