Sony Headphone internal codes and Bluetooth SoCs
![]() |
Sony WF-1000X BT |
In a previous article I outlined many of the current and past Walkman model internal codes Sony uses. While the Walkman models use ICX for their prefix, the headphones use HDX. I will try to keep this updated with the latest information but it is not always possible to find the code, the Bluetooth chip or both.

Most of the information is from FCC documents, Bluetooth certifications, Apple Certifications, Country specific certifications, and from teardowns. Not all of the data in the table is complete and there will be gaps.
Here are the list of the Bluetooth SoCs Sony has used for the past few years in their headphones. I used to have links to the chip pages, but many stopped working, so I removed the links.
- Qualcomm CSR8675
- Qualcomm CSR8670
- Airoha AB1522
- Airoha AB1531
- Airoha AB1552
- Airoha AB1561M
- Airoha AB1562M
- Airoha AB1562A
- Airoha AB1563E
- Airoha AB1565D
- Realtek RTL8763B
- Mediatek MT2811
- Mediatek MT2822
- Mediatek MT2833
- NXP NXH3670
- Sony CXD3277
Sony has switched to the YY naming scheme for all of their Bluetooth devices, like headphones, wireless mice, and wireless keyboards. I suspect Sony still uses the HDX-#### scheme internally for development, as seen with the WF-C500 teardown, but this could be specific to certain models made by OEMs (ex Cresyn).
Here is the latest list (September 22 2025). Please keep in the mind that these codes are not just for wireless headphones, but also for wired, and their accessories like cables, and dongles. I have also added links to the the table of the unreleased models.

Hi! Great post!
ReplyDeleteIs there any chance you know which buttons are used on the HDX-2936 board? I drowned two of them and would like to replace them.
Do you mean what kind of buttons? I do not know the model of buttons, but I can post a photo of the board below from a teardown.
