Information about the fully wireless headphones Sony WF-1000XM4 continues to arrive-dosed and regularly. This time, from the materials of the Bluetooth certification of the Special Interest Group (SIG) and the Federal Communications Commission (FCC), it became known that the novelty will receive support for Bluetooth 5.2. In the certification materials, the headphones are designated “YY2948” — it is known that this is really the code name of Sony WF-1000XM4.
In addition to the previous leaks, this information makes the description of the future Sony WF-1000XM4 even more complete. It is clear that Bluetooth 5.2 has certain advantages over the current Bluetooth 5.1. It is more economical and will provide several synchronous connections at once.
On the other hand, from the latest leak of certification data, it became known that the novelty will not be equipped with aptX or aptX HD codecs. Instead, Sony’s proprietary LDAC Bluetooth codec is not excluded, which can provide the XM4 with the proper level of sound quality.
What will be the Sony WF-1000XM4, whether they will support the 360 Reality Sony Audio format, whether they will receive the DSEE Extreme audio chip working in premium WH-1000XM4 – it is still unclear. Moreover, so far from Sony there is not even confirmation of their development.
