Sony YY2978 Wireless Headset appears on FCC

Another Sony wireless headset has appeared on the FCC, the YY2978.  The first thought that comes into my head is, this looks like the WS-Series Walkman, but this is a headset and not Walkman. So the next thought, could this the production model of the WI-EO600? The original WI-EO600 (YY2962) had a limited production run, so perhaps Sony has decided to have a larger global release.

Update 2

Whatever this headset ends up being, it just showed up on E-ComM, Malaysia’s certification site.

Update

The device has appeared on Korea’s FCC.  The headset is made in Thailand.

If this is the WI-OE600, the label drawing is missing the 2 small extra pieces on the body where the drivers are located. Perhaps these have been excluded from the drawing as they are not necessary for the label position document.

The FCC documents reveal little, the internal battery is a 3.7V one, not 3.85V as with other recent headsets. The testing site is Shenzhen, so I suspect these might be made in China. The Bluetooth software being used is Bluetooth RF Test Tool v5.2.2.16. Digging into some other testing documents, I found the exact same program version and with RTLBTAPP name attached to it. So this appears to be Realtek Bluetooth testing software, and coincidentally the WI-OE600 uses a Realtek RTL8763B chip. Looking back at the original WI-OE600 FCC documents, the same software is used, Ss perhaps this the WI-OE600 production model after all.

I could be wrong and this might end up being a completely different model but gut is telling me this is just the WI-OE600 in production form.

If I find out anything more, I will update the post.
