Sony WF-1000XM6 (YY2985) Import Filing
Back in May. the internal code for the WF-1000XM6 was revealed by none other than Sony in their Sound Connect app. Since that post, not only has Sony removed any mention of the WF-1000XM6 in the app, they also removed all of the YY codes.
Apart from the information from Sony’s app, we had no direct evidence of the WF-1000XM6, until today. An import filing has appeared which shows the WF-1000XM6 (YY2985).

Funny enough, the new earbuds are described as “Headphones without a frame”. The new model was imported into Vietnam for testing, and in black. This import filing is a good indicator that we should see the earbuds later this year. I am hopeful we will see an actual certification soon, which will reveal more details.
I know people have been waiting for some information about the new model, but I have not received anything from my sources yet, but at least we know the earbuds are coming.
Bluetooth SoCÂ
I forgot to add this information earlier. I wrote about the Mediatek MT2855 in previous posts, but only the Google Fast Pair compatibility page showed the chip. But a while back, the chipset was finally certified on Bluetooth SIG. There is no certainty we will see this in the new WF-1000XM6, but it would make sense.

Update 8 – January 22
New import filing from mid December, mock ups in black and silver, confirming the colours again. The import filing is most likely for retail store mockups as the imported is Sony Philippines Inc.


I had my suspicion in the past, but it this info seems to suggest that Goertek is the manufacturer of the WF-1000XM6 earbuds. They do have a factory in Vietnam where the new model will be made. If Goertek sounds familiar, that is because they make the SiPs for Sony’s recent earbud models.

Update 7 – January 11Â
The headset has been imported into India for testing purposes in late November 2025. For comparison, the WF-1000XM5 was imported into India for testing in late April 2023, with the announcement in September 2023. With the headset set to debut earlier than past models, perhaps an announcement in India will also be earlier than September 2026.

Update 6 – December 31Â
A lot more recent import filings. The earbuds were imported into many different countries, possibly for testing.

Update 5 – November 19Â
News is slow on the WF-1000XM6 front, but we have some more import filings, 1 to Vietnam, and 3 to Japan. Maybe they are being imported into Japan for testing or internal review?

Update 4 – October 26Â
New import filing for battery testing for the new WF-1000XM6. At least this is my understanding of the filing description.

Update 3 – October 11Â
Some new import filings have appeared from early August finally. These look to be the molds for the paper box. Unless it is the material for the paper box. Regardless, either Sony has already started production of the boxes and possibly earbuds, or they will soon. Hopefully more import filings will go up soon.

Update 2 – September 20
I would not normally update this post since we have a certification but I feel this information fits better in this post then the cert post. A newer import listing of a mould knife for the WF-1000XM6.

I suspect we will see more import filings, but they could be backdated to August. If any of the import filings reveal anything major, they will go into their own post, otherwise I will just post them here.
Update – July 7Â
I had another import filing from mid March but it did not provide enough context. But now with a second import filing from early May, it makes more sense. We do not have all of the data in the first photo, but the second photo from another import site does. This filing only recently went up online.


We can see HDX-2985. Sony still uses HDX for their headsets internally, and HDX-2985 is the WF-1000XM6. The import filing looks to be for the paper box which holds the charging case. We have the top, bottom, inner, and accessory tray, along with their measurements. The description includes EVT, which stands for “Engineering Validation Test”. From this website (thanks LG), this is the first stage of 3 before a product goes into mass production. Next would come DVT and PVT. DVT is when the model would go for certification. Seeing as these filings are from mid March, I would think Sony has submitted the headset for certification. I hope we see some certifications popping up soon.
Next up, we have this early May import, also using the HDX-2985 code.

This filing has the molds which are used to produce the various parts of the box. The moulds are for the box (top), box (bottom), accessorize tray and inner frame. The various sections match the March filing.
The WF-1000XM5 itself has the same parts, the top and bottom boxes, the inner frame to hold the charging case, and underneath, the accessory tray. We are missing the instruction manual tray present in the WF-1000XM5, so perhaps Sony has removed this from the new model. We can use the dimensions from the import filing to compare it to the WF-1000XM5. Unfortunately I do not own a pair of calipers, so the WF-1000XM5 measurements are from my own headset using a ruler, so not 100% accurate.
| WF-1000XM6 | WF-1000XM5 | |
|---|---|---|
| Box (top) | 84 x 70 x 27.5 mm | 99 x 66.5 x 26.5 mm |
| Box (bottom) | 84 x 70 x 27.5 mm | 99 x 66.5 x 26.5 mm |
| Inner Frame | 81.7 x 67.7 x 26.2 mm | 96 x 60.5 x 25 mm |
| Acc. tray | 80.8 x 66.8 x 13.1 mm | 95 x 60 x 13 mm |
From the table, we can see the box on the new WF-1000XM6 is slightly taller and wider, but the length is less, about 15mm. Using the dimensions of both, here is a comparison photo.

The actual boxes will have rounded corners, which is not possible in the online comparison tool. But what good are case dimensions? Well for one, they reveal that Sony has not decided to go for a different design, ie square case like the LinkBuds Fit. And second, the size of the charging case and earbuds should be similar to the current model. It is definitely possible to make the box smaller. but maintain the similar size of charging case.
We know Sony reduced the battery capacity 12.5%Â on the WH-1000XM6 compared to the WH-1000XM5, so it is possible we will see a similar decrease on the WF-1000XM6. Personally, I would rather Sony keep the same batteries, considering newer more efficient components would help increase the battery life.
Btw, if anyone wishes to 3D model some more accurate comparisons, here are the full dimensions for both models.
- WF-1000XM5 – 99mm x 66.4mm x 53mm
- WF-1000XM6 – 84mm x 70mm x 55mm
End of update.
