A prototype of an upcoming pair of wireless noise canceling headphones from Sony with the Model number YY2948 has been certified by the FCC and Bluetooth SIG and if the code name matches really to that of the Sony WF-1000XM4, we might be in store for a number of major upgrades.

Better battery life, better sound - but no aptX
Choosing to use MediaTek and not Qualcomm for the processor could mean that the Sony WF-1000XM4 will again ignore aptX and aptX HD support. However, The Walkman Blog estimates that the power consumption ratings plUses high could be an indication of LDAC support - which was a notable omission on the XM3.
Unveiled in July 2019, on Sony WF-1000XM3 was acclaimed for its sound profile and effective noise cancellation. Naturally, fans were waiting to see how Sony stood out.
We first heard about the WF-1000XM4 in February, where an alleged retail box revealed a new design and some key specs, like using LDAC - but we hadn't heard whether the headphones would support aptX or not.
