The Sony WF-1000XM4 takes yet another step nearer to launch with Bluetooth SIG and FCC certificates; new MediaTek SoC with Bluetooth 5.2 onboard rules out aptX or aptX HD support

Meanwhile, the FCC describes that the WF-1000XM4 has a MediaTek MT2822S SoC, up from the MT2811S found in the WF-1000XM3.

Meanwhile, the FCC describes that the WF-1000XM4 has a MediaTek MT2822S SoC, up from the MT2811S found from the WF-1000XM3. Based on The Walkman Blog’s findings, the MT2822 has a faster CPU combined with an improved DSP coprocessor. The MT2822 supports up to 24-bit and 192 KHz audio like the MT2811S, but the prior utilises Hardware Active Noise Cancellation (ANC) and hardware gain control, among other capabilities.

The FCC has given a sketch of the WF-1000XM4’s charging case also, although possibly only of the top of its lid. While the existence of some MediaTek SoC rules out the WF-1000XM4 from supporting some aptX codecs, leaked box art points into Sony for example its proprietary LDAC codec. It’s unclear when Sony will launch the WF-1000XM4, but the FCC indicates the earbuds will arrive ahead of September.
