Tech News: Rumor suggests Sony WF-1000XM4 to come with improved battery life and HD audio upscaling.
Watch out for the AirPods, the Sony WF-1000XM4 is the long-awaited successor to one of the best wireless earbuds ever and could come with two major updates. A prototype of an upcoming pair of Sony wireless noise canceling earbuds with model number YY2948 has been certified by the FCC and Bluetooth SIG, and if the codename really matches the Sony WF-1000XM4, we might be interested in some important updates. .
Chief among these is the use of Bluetooth 5.2, which will give the wireless earbuds longer battery life due to lower power consumption and higher bandwidth for data transmission, which could also improve audio.
The FCC filing for the same Sony earphones reveals a new MediaTek MT2822S chip inside, which reportedly brings with it an improved digital signal processor (DSP), hardware ANC, feedforward microphones, voice prompts, and a smaller overall footprint. The FCC documents also include a rendering of the sprout dwellings. While it doesn’t reveal much, it appears to have a somewhat rounder shape, as seen on other recent Sony offerings such as the Sony WF-SP800N.
The choice of MediaTek and not Qualcomm for the processor could mean that the Sony WF-1000XM4 will once again skip aptX and aptX HD support. However, The Walkman Blog believes the higher power consumption could be an indication of LDAC support, which was a notable omission on the XM3.
Revealed in July 2019, the Sony WF-1000XM3s were praised for their sound profile and effective noise cancellation. Understandably, fans waited to see how Sony would outdo themselves.
We first heard about the WF-1000XM4 in February, where an alleged retail box revealed a new design and some key specs – such as the use of LDAC – but we hadn’t heard if the earbuds would support aptX or not.
