Sony WH-1000XM4 passes through Malaysia's SIRIM for Certification

The SIRIM certification does not reveal anything specific or new, but with every new certification this brings the device closer to market. The approval date is January 22nd 2020 as seen above, and looking back at the WH-1000XM3, its date was July 9th, 2018, so around 2 months before debut at IFA 2018.

Sony HDX-2944 certified on Bluetook SIG

Another Sony device has appeared on Bluetooth SIG, the HDX-2944. Unlike the HDX-2947, the HDX-2944 is using the MT2811 Bluetooth chip found in the WF-1000XM3. Therefore, this could end up being either the WF-SP800N or the WF-XB700 in my opinion.

Sony HDX-2947 certified on Bluetook SIG

An unknown Bluetooth 5.0 wireless headset from Sony has appeared on Bluetooth SIG. The possible candidates for the unknown model are as follows: WH-1000XM4, WH-CH710N, WI-SP510, WF-SP800N, and WF-XB700. We can rule out the WF-SP800N since the MT2811 is mentioned in the FCC filing and that chip has been identified as the Airoha AB155x.
