The Sony WF-1000XM4 is well on its way and may arrive sooner than expected. The upcoming pair of TWS earbuds will feature a revised design, improved functionality and possibly even a charging case that can be recharged wirelessly.

The Walkman Blog has revealed more information about the WF-1000XM4, Sony's next premium pair of wireless earbuds. Leaks about the WF-1000XM4 emerged in February, which were then followed last month by Bluetooth SIG and FCC certifications. While the former seemingly revealed the earbud's design, the latter confirmed technical specifications and a revised charging case.

Now, The Walkman Blog has published multiple product renders, including those of the new charging case. Both match previous leaks and confirm that Sony has overhauled the design of both. Details around the charging case remain limited, but its charging output is higher than the WF-1000XM3's. Additionally, a menu in the Xperia 1 III implies that the WF-1000XM4 will support wireless charging, too.

Incidentally, Sony and the FCC's short term confidentiality agreement has been moved forward over three months. Initially, the confidentiality agreement expired in late September, but Sony has amended this to June 9. We should stress that there are no guarantees that Sony will launch the WF-1000XM4 within a month. However, the change indicates that the earbuds will arrive a few months earlier than expected and this side of autumn.

According to previous leaks, the WF-1000XM4 will support Bluetooth 5.2, LDAC and up to 6 hours of battery life from a single charge. The earbuds should support Active Noise Cancelling (ANC) too, although the presence of a MediaTek SoC precludes any Qualcomm aptX, aptX HD or aptX Adaptive support.
