Beware of AirPods, the Sony WF-1000XM4 is the long-awaited successor to one of the best wireless headphones of all time – and they could come with two major upgrades.
A prototype of an upcoming pair of Sony wireless noise canceling headphones with model number YY2948 has been certified by the FCC and Bluetooth SIG and if the code name really matches that of the Sony WF-1000XM4, we might be in store for a number of major upgrades.
Chief among them is the use of Bluetooth 5.2 which will give true wireless headphones better battery life thanks to its low power consumption and higher bandwidth to transmit data – potentially allowing better his.
The FCC filing of the same Sony headphones reveals a new MediaTek MT2822S chip inside, which would bring an improved digital signal processor (DSP), hardware ANC, feedback mics, voice prompts, and a smaller overall footprint.
FCC documents also include a rendering of the bud housing. While that doesn’t reveal much, it does appear to be a bit rounder, as seen on other recent Sony offerings such as the Sony WF-SP800N.
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 believes that the higher power consumption ratings could be an indication of LDAC support – which was a notable omission on the XM3.
Unveiled in July 2019, the 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 the use of LDAC – but we hadn’t heard if the headphones support aptX or not.
So far, things are not going well in this department.
Of course, Sony has yet to confirm any of the information from the leak and the FCC filings, so it’s best for now to treat everything with a grain of salt until we get an official word. .
