Sony WF-1000XM4 earbuds could launch this twelvemonth — hither'south proof
A new pair of Sony wireless headphones take been discovered in an FCC filing, potentially revealing the first Sony WF-1000XM4 specs — also as a charging example design.
Spotted by the Walkman Blog, the filing doesn't proper noun the WF-1000XM4 — Sony'due south expected answer to the Apple AirPods 3 and AirPods Pro 2.

The charging case design image is simply drawn and only shows a tiptop-downward view, but is consequent with the long, slim cases of previous Sony earbuds like the original WF-1000XM3 and the WF-SP800N. Further show that this filing covers the WF-1000XM4 comes in a reference to the product as a "wireless noise cancelling stereo headset" — the WF-1000XM3 featured agile noise cancellation (ANC) and the WF-1000XM4 is all merely guaranteed to keep this major feature.
As for new upgrades, the earbuds in this certificate apply Bluetooth 5.ii. That would grant the WF-1000XM4 a number of wireless performance benefits over the WF-1000XM3 likewise as the current-gen AirPods Pro, both of which use Bluetooth 5.0. For case, the WF-1000XM4 could apply the Low Free energy (LE) Audio feature in Bluetooth v.2 to play music with lower bandwidth and power drain.
Bluetooth five.2 also introduces the Isochronous Channels feature, which more than hands allows a single pair of headphones to connect to multiple source devices at once, as well as to switch betwixt them seamlessly.
It likewise looks like the WF-1000XM4 will include an upgraded MediaTek SoC, the MT2822S. This chip hasn't been publicly detailed even so, but the Walkman Blog claims it'south a rebranded Airoha AB1568. If so, this would give the WF-1000XM4 the same 24-bit/192 kHz lossless audio back up as the WF-1000XM3, while significantly improving its power management.
The filing fifty-fifty contains a hint at a potential release window, with the FCC's brusque-term confidentiality understanding catastrophe on September 27 of this year. Any this new pair of headphones is, Sony will desire to formally reveal it before then, so the WF-1000XM4 could well release earlier Winter 2021.
This would likely bring the Sony buds into competition with the AirPods 3, which is too rumored to launch in the second half of 2021, besides equally the upcoming Google Pixel Buds A. With ANC and meridian-of-the-line Bluetooth connectivity, though, the Sony WF-1000XM4 would exist a more premium proposition than either.
