Sony LinkBuds Clip (WF-LC900) FCC Teardown
The LinkBuds Clip were announced earlier this week, and the lack of LC3 made me wonder if Sony has switched up the Bluetooth chipset from the V2 (MT2833), to something else. The FCC internal photos became available on Friday, so time to dive in to see what they reveal.
The FCC teardowns for the LinkBuds Fit and LinkBuds Open can be found below. Unfortunately they are not very detailed.

This will not be a step by step teardown as the photos in the files just show the components and not the process to take the earbuds apart. For a step by step teardown, we need to wait for 52Audio or iFixit.
We will begin with the case. The lower half of the case looks to be clipped in on the sides, but also possibly glued in as well. I think there is glue or tape on the bottom of the middle section (red arrows). So in order to take the bottom piece off, one may need to heat the front part of the bottom piece to soften the adhesive.
There does not appear to be much empty space in the bottom section, so questionable whether a wireless charging coil would even fit inside the case, without a redesign to the case.
We have no comparison photos of the LinkBuds Fit and Open cases, so it is uncertain how much they share in terms of design and build. The battery compartment is screwed into the middle section with 2 screws. This also holds the case PCB in place.
The battery is connected to the case PCB using a connector (red arrow), which means relatively easy battery replacement in the future.

The case battery is held on with double stick tape.
The battery in the FCC photos is from Springpower, but there are actually 3 suppliers according to the Taiwanese certification, with the same rating and capacity, 3.85V, 500mAh.
- VDL –Â model 772130
- Highpower – model 772030
- Springpower – model 772030
